Hymenium are present on both surfaces of the gills. The hyphae are compact in the trama. Another secotioid Agaricus, A. deserticola, formerly known as Longula texensis, is fairly common in the Central Valley along edges of agricultural fields and waste areas. Agaricus xanthodermus looks similar to the field mushroom (Agaricus campestris), but when the surface of the cap or stem is scraped it stains a distinct yellow colour.With time, the yellow stain fades to dull brown. In basidiocarp of Agaricus campestris, each gill has (1) Two zones of monokaryotic hyphae (2) Three zones of monokaryotic and diploid hyphae Agaricus deserticola, commonly known as the gasteroid agaricus, is a species of fungus in the family Agaricaceae.Found only in southwestern and western North America, A. deserticola is adapted for growth in dry or semi-arid habitats. note inrolled cap margin, even at age. this Agaricus does not strike me as deserticola either, but you held it in hand.

Fill in the table below with the functions of the major structures of the mushroom. Atkinson claims that the gill rudiments appear first in a longitudinal medi'an section of the young carpophore as two deeply stained areas. Critically observe and identify different species representing the major lineages of Fungi Mushrooms in the genus Agaricus have a worldwide distribution, with up to 90 species recorded in Europe.The genus includes the most economically important and commercially cultivated mushroom in the world, A. bisporus (button mushroom) as well as many other edible species [].Some Agaricus species are inedible, including A. placomyces and A. pseudopratensis Bohus, which are … (formerly Psalliota sp.).
