Russulales > Russulaceae > Russula. Russula brevipes creates a choice edible and according to Tom Volk’s can give your lobster chowder a boost. Russula brevipes is also known as the short stemmed russula. 1) R. brevipes has an acrid-tasting variety! [8] The milk-cap mushroom Lactifluus piperatus can be distinguished from R. brevipes by the production of latex when the mushroom tissue is cut or injured. The fungus grows in a mycorrhizal association with trees from several genera, including fir, spruce, Douglas-fir, and hemlock. Russula brevipes is a species of mushroom commonly known as the short-stemmed russula or the stubby brittlegill. Identifying the Russula family (in most cases) is pretty easy, they are very common, very colourful and lots of them are edible! Fairly common and widespread in woodland that contains broadleaf trees, Russula delica occurs throughout Britain and Ireland but is reported more frequently from regions of alkaline or neutral soil. However Lactarius piperatus has an exceedingly hot flavor that renders it inedible for most people-- but that hotness is neutralized by the parasite Hypomyces , making it very delicious. The surface of the mushroom becomes bright orange or reddish-purple and unpalatable host mushrooms are transformed into a delicious edible. Lactarius piperatus has a hot, peppery flavour that makes it inedible for most of us but the parasitic mold does help neutralize the flavour and this combination can make its way to the dinner table.

russula brevipes edible

- December 6, 2020 -

[12], The variant R. brevipes var. [9] In western North America, where the mushroom is quite common, it is encountered most frequently in late autumn. More acrid than var. Similar to R. brevipes in overall morphology, it has somewhat larger spores (9–12 by 7–8.5 µm) with a surface ornamentation featuring prominent warts interconnected by a zebra-like patterns of ridges. Not only are both of those mushrooms edible, but the lobster mushrooms infection actually changes them completely into, well, lobster mushrooms. [15] R. angustispora is quite similar to R. brevipes, but has narrower spores measuring 6.5–8.5 by 4.5–5 µm, and it does not have the pale greenish band that sometimes develops in the latter species. There are, of course, many exceptions to the drop-kick rule (such as the tough Russula brevipes and the very dense Russula compacta group), but it's fun to try anyway, especially in frustration in trying to identify most Russula species. Short-stalked russula2 photograph by Alexander H. Smith with permission from the Denver Botanical Garden. Short-stalked russula partly hidden under forest litter, photograph by David Carmean. [11] The spore print is white to light cream. This fungus is edible but is best when parasitized by the ascomycete (a fungus like yeast) Hypomyces lactifluorum. In reality the mushroom originally was a Russula brevipes, a commonly white russula found in the Pacific Northwest. brevipes except for faint blue-green gill color, especially at top of stipe where tint may appear as a colored apical ring. [21] In contrast, there was little genetic differentiation observed between populations sampled from a smaller area (less than approximately 1000 meters). & Bruns, T. D. Extreme specificity in epiparasitic Monotropoidaeae (Ericaceae): widespread phylogenetic and geographical structure. In the forest, caps can be completely invisible, making only a bulge covered by duff and soil. They become more palatable once parasitized by the ascomycete fungus Hypomyces lactifluorum, a bright orange mold that covers the fruit body and transforms them into lobster mushrooms. In this form, the surface of the fruit body develops into a hard, thin crust dotted with minute pimples, and the gills are reduced to blunt ridges. Taste not distinctive. Russula benwooii is often mistaken for a species in the complex of the shrimp russula, Russula xerampelina, but it is less likely to stain brown on the stem and it lacks the fishy or shrimp-like smell. This common russula is initially white, but it soon develops tan, brownish, or flat-out orangish brown colors—though it can also remain fairly pale overall. Luckily for the mushroom hunter, H. lactifluorum is either an exceptional taxonomist or produces compounds that neutralize the host mushroom’s toxins. [16], It is a common ectomycorrhizal fungus associated with several hosts across temperate forest ecosystems. A good test for Russulas is the taste test, if a tiny amount is placed on the tongue and chewed a burn like chilli means the mushroom is poisonous, a pleasant mushroomy taste means it is edible. 1. https://en.wikipedia.org/w/index.php?title=Russula_brevipes&oldid=952361562, Creative Commons Attribution-ShareAlike License, This page was last edited on 21 April 2020, at 21:27. [4] The cap cuticle is arranged in the form of a cutis (characterized by hyphae that run parallel to the cap surface) comprising interwoven hyphae with rounded tips. Considered edible. The specific epithet brevipes is derived from the Latin words brevis "short" and pes "foot", hence "short-footed". Robert Shaffer summarized the taxonomic conundrum in 1964: Russula delica is a species that everybody knows, so to speak, but the evidence indicates that R. delica sensu Fries (1838) is not R. delica sensu Singer (1938), which in turn is not R. delica sensu Kühner and Romagnesi (1953)… It is best to use R. brevipes for the North American collections which most authors but not Kühner and Romagnesi (1953), call R. delica. The fungus grows in a mycorrhizal association with trees from several genera, including fir, spruce, Douglas-fir, and hemlock. [21], Studies have demonstrated that geographically separated R. brevipes populations (globally and continentally) develop significant genetic differentiation, suggesting that gene flow between these populations is small. If possible, save the mushrooms or some of the leftover food containing the mushrooms to help confirm identification. I have found no records of this species from North America, but a very similar brittlegill Russula brevipesis common across much of the US… Fruit bodies are white and large, with convex to funnel-shaped caps measuring 7–30 cm (3–12 in) wide set atop a thick stipe up to 8 cm (3 in) long. brevipes Peck. Cooks love this mushroom for ease of … . A choice edible mushroom that is delicious and meaty. [14] Another lookalike, R. vesicatoria, has gills that often fork near the stipe attachment. The fungus grows in a mycorrhizal association with trees from several genera, including fir, spruce, Douglas-fir, and hemlock. [10] The flesh of the mushroom—normally brittle and crumbly—becomes compacted and less breakable. It is widespread in North America, and was reported from Pakistan in 2006. However, many Lactarius species are poisonous or too peppery for most people to eat. [26], Sesquiterpene lactones are a diverse group of biologically active compounds that are being investigated for their antiinflammatory and antitumor activities. It is one of several Russula species harvested in the wild from Mexico's Izta-Popo Zoquiapan National Park and sold in local markets in nearby Ozumba. Russula brevipes. [3] It is classified in the subsection Lactaroideae, a grouping of similar Russula species characterized by having whitish to pale yellow fruit bodies, compact and hard flesh, abundant lamellulae (short gills), and the absence of clamp connections. Russula brevipes is a known edible, so it's not too surprising that the complex of these two species is edible. Almost white spores . Regionally, the short-stalked russula is known from Alaska, BC, and southwards to forested areas of Washington and Oregon1. Tricholoma apium. Russula brevipes, with their low stature and brownish scales, make for especially deceptive and frustrating pine mushroom lookalikes. To add to the confusion, Rolf Singer and later Robert Kühner and Henri Romagnesi described other species they named Russula delica. [2] In a 2012 publication, mycologist Mike Davis and colleagues suggest that western North American Russula brevipes comprise a complex of at least four distinct species. [11] The European look-alike R. delica is widely distributed, although rarer in the northern regions of the continent. Edible, but usually mediocre. These gifts of the forest with colorful hats are not delicious, although their taste is not inferior to other mushrooms. However, if a Russula brevipes is attacked by parasitic ascomycete it is turned from white to orange. [17] The fungus has been reported in Pakistan's Himalayan moist temperate forests associated with Pinus wallichiana. Poison Centres provide free, expert medical advice 24 hours a day, seven days a week. Engulfed by a parasite in rich conifer humus, and the host mushroom may hold its shape or another odd shape, but it is the fresh steamed red or red orange lobster color that … 2) Russula vesicatoria 3) Russula piperatus & Others SP dark cream Taste acrid, bitter. [1] The nomenclatural database Index Fungorum does not consider these varieties to have independent taxonomical significance. [25], Fruit bodies are commonly parasitized by the ascomycete Hypomyces lactifluorum, transforming them into an edible known as a lobster mushroom. Beug, M. W., Shaw, M. & Cochran, K. W. Thirty-plus years of mushroom poisoning, Summary of the approximately 2,000 reports in the NAMA case registry. Russula brevipesvar. lactifluorum Bluish-green tinted gills & stalk apex. They found that the infected and edible lobster mushroom mostly contains the DNA of the parasitic fungus with only trace amounts of … Russula brevipes is a non-descript edible species that tends to assume the flavors of meats and sauces it is cooked with. [24] The mushrooms are suitable for pickling due to their crisp texture. It is the product resulting of the infection, most commonly of Russula brevipes by Hypomyces lactifluorum. Summary 4 Russula brevipes is a species of mushroom commonly known as the short-stemmed russula.It is edible, although its quality is improved once parasitised by the ascomycete fungus Hypomyces lactifluorum, transforming it into an edible known as a lobster mushroom.. Bioactive compounds 5 Sesquiterpene lactones are a diverse group of biologically active compounds that are … Spores: 8-10 x 6.5-9 µm, with scattered warts. The bright orange-red parasitic fungus actually transforms an ordinary nonedible white mushroom (possibly a Russula brevipes or Lactarius piperatus) into an excellent edible mushroom, by changing its color, shape, and flavor. Shaffer defined the Russula brevipes varieties acrior and megaspora in 1964 from Californian specimens. [9], Fully grown, the cap can range from 7 to 30 cm (3 to 12 in) in diameter, whitish to dull-yellow, and is funnel-shaped with a central depression. The mushrooms of Russula brevipes often develop under masses of conifer needles or leaves of broadleaved trees, and fruit from summer to autumn. This beautiful mushroom is fairly common in the oak forests of eastern North America. On mainland Europe this brittlegill occurs from Scandinavia down to the Mediterranean countries. [22] R. brevipes is one of several Russula species that associates with the myco-heterotrophic orchid Limodorum abortivum. [10] R. brevipes var. Some early 20th-century American mycologists referred to it as Russula delica, although that fungus was described from Europe by Elias Fries with a description not accurately matching the North American counterparts. These mushrooms are also used as a filling for pies. Its dry cap and stem are bright yellow, and the cap margin is only faintly lined, if it is lined at all. British Columbia: 604-682-5050 or 1-800-567-8911. An entertaining way to confirm a mushroom is a Russula is to throw it at something (a tree, the ground, a friend) and watch for its explosion into little pieces. Siegel and Schwartz 3 warn that some forms of short-stalked russula taste good while others are 'down right awful'. The mold attacks and grows on Short-stalked White Russula (Russula brevipes) and Peppery Milky (Lactarius piperatus) transforming and changing their appearance and taste. It is initially white but develops yellowish-brownish discolorations with age. [27][28] Some of these compounds have been isolated and chemically characterized from Russula brevipes: russulactarorufin, lactarorufin-A, and 24-ethyl-cholesta-7,22E-diene-3β,5α,6β-triol. by Michael Kuo. In general, members of the genus Russula are fairly large, gilled with a white underside and a cap that most often is a variation of white or red. Russula brevipes is a species of mushroom commonly known as the short-stemmed russula or the stubby brittlegill. Other related Russula species with a similar range of spore ornamentation heights include Russula delica, R. romagnesiana, and R. United States (WA, OR, ID): 1-800-222-1222. The stipe is 3–8 cm long and 2.5–4 cm thick. Habitat: In all kinds of forests, both with oaks (Quercus spp.) Edible russula is one of the most common mushrooms in our latitudes. It is a edible by not choice. In cooking, all varieties of edible russula are used in boiled, fried, salted and pickled forms. [18] Fruit bodies grow singly or in groups; fruiting season occurs from summer to autumn. Russula brevipesis one of the most common Russulaspecies on the west coast, and is easily identified by its stature, large size, and white coloration which does not stain when handled. To speculate, different species within the complex may differ in flavour. All strains were maintained on Malt extract … There is no known species of Russula that is deadly and the Russulas that have a mild taste are edible. Short-stalked White Russula (Russula brevipes) The Short-stalked White Russula (Russula brevipes) is a large mushroom in the Russula Family (Russulaceae) and order Russulales. This test should only be attempted when you are certain you have a mushroom from the Russula … "Biodiversity of mushrooms and ectomycorrhizas. Today's mushroom, Russula brevipes is one of the most common mushrooms this time of year in this area. Laperriere and his team extracted DNA from infected (edible) and non-infected (non-edible) mushrooms collected from various sites around Quebec. Under pines or in mixed woods. There has been considerable confusion in the literature over the naming of Russula brevipes. A post by my talented student Ben Hoffman, who took my Mushrooms class in 2013. Russula's are very common, and infamous for being very hard to positively identify. Six wild edible mushroom cultures namely Russula lepida, Russula brevipes, Russula nigricans, Pleurotus sajor-caju, Lentinus tuberregium and Calocybe indica were used for the study of biomass production in different medium. The gills typically bruise brownish, and the stem is often fairly short in proportion to the cap ( brevipes means "short-stemmed"), and … Toxicity Mild-tasting russulas are often eaten. If it is acerbic, it is a good indication that it will result in intestinal distress. The resulting mushroom is called a Hypomyces lactifluorum (or Lobster) and it is them a very desirable edible. Some are edible, some are acrid. Russula brevipes Peck., is widely distributed t hroughout North America, and mai nly associated with species of Abies, Picea, Tsuga and Pseudosuga (Stani s, 1979; Kraiger et al , 1995). Taste: Mild to acrid. [23], Russula brevipes is a non-descript edible species that tends to assume the flavors of meats and sauces it is cooked with. . There are no cystidia on the cap (pileocystidia). Cup: None. Gills: Very crowded, with many short gills interspersed among the long gills, decurrent onto the stem, white. Avoid eating acrid/hot specimens, which may be cascade russulas rather than short-stalked russulas. [10], Spores of R. brevipes are egg-shaped to more or less spherical, and measure 7.5–10 by 6.5–8.5 µm;[9] they have a partially reticulate (network-like) surface dotted with warts measuring up to 1 µm high. 'Short-footed Russula'. They contain only 19 kcal, a lot of protein, vitamins, carbohydrates and microelements. Russula brevipes was initially described by American mycologist Charles Horton Peck in 1890, from specimens collected in Quogue, New York. The name, R. brevipes, is attached to a type collection, has a reasonably explicit original description, and provides a stable point about which a species concept can be formed.[1]. The lecithin contained in the composition prevents cholesterol deposition. acrior. It is widespread in North America, and was reported from Pakistan in 2006. Treatment: Contact your regional Poison Control Centre if you or someone you know is ill after eating russulas. Oct 29, 2013 - Based on noted mycologist David Arora's list, I have compiled photos and a brief description, so we can become more familiar with these common mushrooms. Hypomyces luteovirens (also Russula brevipes var. Lobster mushroom is a wild edible mushroom with potential commercial value. This study undertook quantitative polymerase chain reaction analysis of tissues sampled at different infection stages, to investigate R. brevipes/H. Russula brevipes is a North American species closely related to Russula delica in a group of Russula species resembling members of Lactarius, with white-to-yellow cap colors staining sordid yellow-to-umber in age, whose flesh is compact and unchanging in color, with abundant lamellulae, and having a blue-green reaction to the application of iron salts. acrior Shaffer has a subtle green shading at the stipe apex and on the gills. Russula brevipes var. One of the most common hosts is Russula brevipes, which is edible (but not especially good). megaspora has spores measuring 9–14 by 8–12 µm. Some of the cover of litter usually remains adhering to the cap. The gills are narrow and thin, decurrent in attachment, nearly white when young but becoming pale yellow to buff with age, and sometimes forked near the stipe. It is widespread in North America, and was reported from Pakistan in 2006. brevipes. Neither the bruised stem nor the sliced flesh turns grayish, and the taste is mild. Forms of the mushroom that develop a bluish band at the top of the stipe are sometimes referred to as variety acrior. Odour: Mild. Although edible, Russula brevipes mushrooms have a bland or bitter flavor. pseudodelica.[1]. Though in other European countries some are collected regularly for eating, and I … Bergemann, S. E. & Miller, S. L. Size, distribution, and persistence of genets in local populations of the late-stage ectomycorrhizal basidiomycete. The gills on the cap underside are closely spaced and sometimes have a faint bluish tint. Bidartondo, M. I. Funnel-shaped, large, white brittle caps C Like var. Russula can be easily identified by the "drop-kick" method-- the mushroom should shatter into a million pieces if properly kicked. [1], The subalpine waxy cap (Hygrophorus subalpinus) is somewhat similar in appearance to R. brevipes but lacks its brittle flesh, and it has a sticky, glutinous cap. [13] It is one of several Russula species harvested in the wild from Mexico's Izta-Popo Zoquiapan National Park and sold in local markets in nearby Ozumba. and with conifers including pines (Pinus spp. Fortunately, Russula brevipes are an edible, although unappetizing mushroom. One of the more common Russulas that fall into this category is the Russula emetica , the species name derived from the Greek emetiko s, to vomit, reported to be a strong purgative. Typical hosts include trees in the genera Abies, Picea, Pseudotsuga, and Tsuga. [4] According to MycoBank, the European species Russula chloroides is synonymous with R. brevipes,[5] although Index Fungorum and other sources consider them distinct species. Comments. The cap starts out rounded with a central depression, and becomes more vase-like depressed with a wavy edge. Stem: 2-8 cm long x 2-5 cm wide, white. [13] The Pacific Northwest species Russula cascadensis also resembles R. brevipes, but has an acrid taste and smaller fruit bodies. [29], "Although attractive when clean and crisp, this harmless, prolific mushroom is constantly maligned because it mimics prized edibles such as the white. The development is expressed in relation to the identity of the fungus associated with the maternal plants from which the seed was derived and that of the fungi initiating the germination. Thus, for example, b X b = Russula brevipes as maternal fungus X R brevipes as the fungus which initiated germination. [19] The mushrooms are usually found as "shrumps"—low, partially emerged mounds on the forest floor,[20] and have often been partially consumed by mammals such as rodents or deer. Ring or veil: None. ), and Douglas fir (Pseudotsuga menziesii), often only visible as a raised piece of forest floor; ectomycorrhizal4. Russulae are low-calorie and mushroom-flavored mushrooms. Spores are roughly spherical, and have a network-like surface dotted with warts. The only two species that we know are infected by the lobster mushroom fungus in North America are Russula brevipes and Lactifluus (Lactarius) piperatus. Poison Control: Amanita aprica. Grows under hardwoods/conifers. Cap: 7–30 cm in diameter. 'Stubby Short-footed Russula'. [10] The mushroom sometimes develops a pale green band at the top of the stipe. [6] Common names used to refer to the mushroom include short-stemmed russula,[7] short-stalked white russula,[8] and stubby brittlegill. The colour is white to cream, often with brown stains. ''Russula brevipes'' is a species of mushroom commonly known as the short-stemmed russula or the stubby brittlegill. The former is characterized by a greenish-blue band that forms at the top of the stipe, while the latter variety has large spores. The mushrooms are suitable for pickling due to their crisp texture. Short-stalked White Russula Russula brevipes Edible SP white to pale cream. The Russulas are often overlooked as as edible option in the UK. Russula flavida [ Basidiomycetes > Russulales > Russulaceae > Russula. Russula brevipes creates a choice edible and according to Tom Volk’s can give your lobster chowder a boost. Russula brevipes is also known as the short stemmed russula. 1) R. brevipes has an acrid-tasting variety! [8] The milk-cap mushroom Lactifluus piperatus can be distinguished from R. brevipes by the production of latex when the mushroom tissue is cut or injured. The fungus grows in a mycorrhizal association with trees from several genera, including fir, spruce, Douglas-fir, and hemlock. Russula brevipes is a species of mushroom commonly known as the short-stemmed russula or the stubby brittlegill.

Fairly common and widespread in woodland that contains broadleaf trees, Russula delica occurs throughout Britain and Ireland but is reported more frequently from regions of alkaline or neutral soil. However Lactarius piperatus has an exceedingly hot flavor that renders it inedible for most people-- but that hotness is neutralized by the parasite Hypomyces , making it very delicious. The surface of the mushroom becomes bright orange or reddish-purple and unpalatable host mushrooms are transformed into a delicious edible. Lactarius piperatus has a hot, peppery flavour that makes it inedible for most of us but the parasitic mold does help neutralize the flavour and this combination can make its way to the dinner table.
