Xeromphalina kauffmanii [ Basidiomycetes > Agaricales > Tricholomataceae > Xeromphalina . . . ] by Michael Kuo This tiny mushroom often fruits in stunning numbers on stumps and dead logs in hardwood forests. It has a white spore print, gills that run down the stem, and a wiry stem that is yellow above, and brownish below. On close inspection, the gills are often connected by many cross-veins--one of the defining features of the genus Xeromphalina. The very similar Xeromphalina campanella appears on the wood of conifers and has slightly larger spores. Description: Ecology: Saprobic on the dead wood of hardwoods; growing in dense clusters (sometimes by the hundreds!) on stumps and logs, or occasionally in small clusters or even alone; spring and summer; widely distributed in eastern North America. Cap: .5-2.5 cm; convex to broadly convex or flat overall, but with a deep central depression; bald; lined or pleated on the margin; brownish yellow, rusty, or yellowish, paler towards the margin; fading. Gills: Running down the stem; more or less distant; with many cross-veins; pale yellow. Stem: 1-4 cm long; 1-2 mm thick; more or less equal; rusty yellow above, darker brown below; smooth or finely hairy; rather wiry. Flesh: Insubstantial. Odor and Taste: Taste mild; odor not distinctive. Spore Print: White. Microscopic Features: Spores 4-6 x 2.5-3 µ; elliptical; smooth; faintly amyloid. Pleuro- and cheilocystidia fusiform to narrowly clavate; up to 27 x 8 µ. Caulocystidia clavate to fusiform; thin-walled. Clamp connections present. REFERENCES: A. H. Smith, 1953.
