An agaric (/ ˈ æ É¡ ər ɪ k, ə ˈ É¡ ær ɪ k /) is a type of mushroom fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. Portion of vesiculose trama in the pileus of a Russula. and we have this from a DNA study that included four Gymnopilus penetrans specimens and two specimens of Gymnopilus sapineus (Guzmán-Dávalos et al., 2003): There you have it. In certain genera, particularly in Coprinus when the basidiocarp is mature, a process of autodigestion or autodeliquescence begins. Description. (Saccardo, 1887; Hesler, 1969; Smith, Smith & Weber, 1979; Arora, 1986; Phillips, 1991/2005; Lincoff, 1992; Barron, 1999; Guzmán-Dávalos et al., 2003; McNeil, 2006; Miller & Miller, 2006.) Etymology: atrodicus means black disc, and here refers to the dark disc of pileus surface. Agaricus is a genus of saprobic Basidiomycetes including species of nutritional and medicinal interest. Material examined: THAILAND, Chiang Mai Prov., Mae Sa Waterfall, 14 September 2012, collector Jie Chen & Asanka Bandara, LD 2012185 (MFLU12-1010 holotype), (isotype, HMAS). Pleurocystidia and cheilocystidia both present (but the former scarcely projecting beyond the basidia); variously shaped. (i) Grows as a saprophyte in decaying organic substances, such as cow dung, crop field, tree trunk, a heap of hays, etc. Kuo, M. (2007, February). Description – Pileus 42–98 mm in diam., convex and umbonate, cap margin entire, surface dry, covered with appressed, triangular … More, I'm sure, than you ever wanted to know about Gymnopilus sapineus and Gymnopilus penetrans .

Retrieved from the MushroomExpert.Com Web site: http://www.mushroomexpert.com/gymnopilus_sapineus.html. These species have been so thoroughly confused by so many authors over the past 200 years that I have decided to return almost to Square One, with Elias Fries's 1821 account; see the discussion below if you are interested. On the underside of the pileus are fine, feathery gills which extend from the center of the pileus to the outer edge. Classification of Agaricus campestris Agaricus (=Psalliota) is a saprophytic fungus which occurs on dead and decaying leaves, wood logs, manure piles and other similar surroundings in rainy season. Zhao & K.D. The pileus is then quite regular in … & Gooss.-Font (Heinemann 1956; Kerrigan et al. Agaricus atrodiscus L.J. The margin is incurved, then decurved, overlapping the gills. Agaricus campestris is the most common ‘field mushroom’. According to the phylogenetic analysis, A. atrodiscus appears as an unbranched lineage arising near the common ancestor of the clade named Xan III by Thongklang et al. (Europe, Asia, and America, in dry places, especially in dry pine woods.) Herb. (2014), which is one of the three major clades constituting the section Xanthodermatei also in our tree, Agaricus atrodiscus (holotype) a Cheilocystidia b Basidia c Basidiospores d Pileipellis. I found this conflict irritating enough that I followed it all the way back to its source--and the culprit appears to be old Elias Fries, whose 1821 description of Agaricus penetrans is worded a little confusingly. Though he named Agaricus penetrans seven years earlier in 1815, in 1821 he described Agaricus sapineus as new and called his previous species, Agaricus penetrans, a form of the new species. Schäffer’s reaction negative. 418 Agaricus L. is a large and well-known edible mushroom genus that also includes a small number of species that are toxic if eaten (Kerrigan et al. Brain, softening of. . The upper end of gills is attached to the lower surface of pileus. Agaricus exilissimus L.J. Chen, Callac, R.L. Figure 240. According to regional lore, Agaricus blazei was first believed to have medicinal properties when outsiders noted that the people of Piedale rainforest of Brazil, who consumed the mushroom as part of their diet, had lower rates of aging-related disorders like cancer and heart disease.1 Alternative practitioners believe that many of the compounds in the mushroom (including isoflavonoids and plant-based steroids) can prevent or treat certai… Peterson, Desjardin & Hemmes and A. xanthosarcus Heinem. The pileus diameter of A. microvolvatulus and A. xanthosarcus can reach to 10 cm, but they differ in having a distinctively bulbous stipe (Heinemann 1956; Thongklang et al. The basidia of agaricus are the cells on the apex of which the spores of such plants are formed. Both stipes and pileus are formed of compact mass of hyphae. other Agaricus species are its chain-like cheilocystidia, longer basidiospores, NaOH reaction turns weakly green, odor of phenol. Habitat and distribution: scattered or gregarious on soil, under Bamboo. In general, Agaricus mushrooms are medium-sized to large and display boring colors. One of these is the presence of a pileus, or cap, which tops the mushroom in a similar fashion to the canopy of an umbrella. Pileus 90–130 mm diam. Hyde. Trituration of the carefully dried-up cap (pileus), or tincture of the fresh fungus. 2012). The sporophore emerges from an extensive underground network of threadlike strands . but if you have been struggling to figure out which of the two names best matches your collection, I hope I have convinced you that you have better things to do.
