Amanita gemmata
3-766.44.00English: Gemmed amanita; Jonquil amanita; European gemmed Amanita.
German: Narzissengelbe Wulstling.
Synonym: Agaricus gemmatus; Amanitopsis gemmata; Amanitaria gemmata; Venenarius gemmatus.
Region: Europe, Asia, from Iran to China, North America, Mexico, Dominican Republic, South America, from Chile to Colombia.
Habitat: sandy and slightly acidic soils; coniferous and mixed forests; alongside paths and roads; fruits in summer and fall; mycorrhizal with Picea abies, Arctostaphylos, Pinus contorta, Pinus pinaster.
Content: muscarine, muscimol, ibotenic acid.
Use: toxic.MycologyType: mycorrhizal; singly or in groups; no distinctive odour.
Cap: dull creamy yellow to golden yellow to buff; 2 to 12 cm diameter; sticky when moist; with white warts, flimsy, easily washed by rain or detached; initially convex, flattens when mature; flesh is white and does not change colour when cut.
Hymenium: gills white and closely spaced; adnate to adnexed.
Stem: pale yellow; 4 to 12 cm long, 5 to 19 mm thick; with ring; white volva at the base.
Spore print: white.
Spores: thin-walled; roughly elliptical, ellipsoid; 8 to 10 by 6 to 8 μm; no amyloid; smooth; contain one to several small oil droplets; basidia are usually four-spored, club shaped, and measure 30 to 40 by 8 to 11 μm.TaxonomyAmanita gemmata resembles the false death cap, tawny grisette and panther cap mushrooms. Some mycologists believe that Amanita gemmata is not different from Amanita russuloides. Two molecular studies show that Amanita gemmata is part of a clade within Amanita with its close relatives Amanita muscaria, Amanita farinosa and Amanita roseitincta.
