Family: Tricholomataceae
Collection date: October 8, 2011
Habitat: Growing on leaf litter
Location: Hiram field station
Description: Can be found growing individually, but usually found growing in tight dense clusters. Widely distributed throughout the summer and fall. The cap is about 1-4 cm; oval or bell-shaped when young, becoming broadly bell-shaped or convex; sticky to slimy when wet; bald; bright orange, fading to dull orange and eventually almost white; sometimes develops olive green stains when mature; the margin sometimes becomes lined. The gills are attached to the stem; close or crowded; the edges are bright orange while the faces of the gills are orangish to creamy. The stem tends to be 3-7 cm long; 2-4 mm thick; hollow; smooth; fairly tough and cartilagenous; sticky when wet; the base covered with orange to whitish powder or dust; orange or orangish yellow, but paler near the apex (Kuo, 2010).

Keying steps:
Key to the Basidiomycetes1A. Basidia and spores borne externally (on the exposed surfaces of gills, tubes,
spines, branches, lobes, etc.); spores forcibly discharged at
maturity, i.e., a spore print often (but not always) obtainable; fruiting body with a cap and stalk, or clublike,
or branched, or bracketlike, or crustlike (without a stalk or sometimes without a cap) or lobed or bloblike, etc. ... 2

3A. Underside of cap with radiating blades (gills)... Agaricales p. 59
