Agrocybe pediades



Cortinarius husseyiKey to Gilled Mushrooms     Key
This is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.



TricholomaAgaricales     Order
Fruiting body containing fibers (usually in the stalk)



Inocybe pyriodoraBrown, Olive, Orange or Tan Spored     Suborder
Gills not free
Spore print tan, orange, deep ochre, yellowish olive, olive brown, rusty or cinnamon brown or deep brown
Ring usually either absent or not membranous



Pholiota albocrenulataLignicolous Brown Spored     Family
Growing on wood



Gymnopilus spectabilisMedium To Big Lignicolous Brown Spored     Subfamily
Cap usually more than 2" across, and sometimes up to 8; usually tan, yellow, or pumpkin-colored


AgrocybeAgrocybe     Genus
Cap dull brown to tan; glabrous (occasionally slimy or viscid); often cracking open like an overripe tomato in age; usually 2-3" across
Fruits in great quantity in wood chips in the springtime
Growing either on hardwood or in grass

Comments

A. E. Bessette, D. W. Fischer & A. R. Bessette (1997) synonymizes this species with Agrocybe semiorbicularis; R. Phillips (1991) keeps them separate. Arora (1986) summarizes the issues well, I think, by saying that "Agrocybe semiorbicularis is said to have a slightly viscid cap and broader spores, but is otherwise identical." For the splitters among you, the spore ranges that R. Phillips (1991) gives are 9-13 x 6.5-7.5 Ám for Agrocybe pediades, and 11-13 x 7.5-8 Ám for Agrocybe semiorbicularis
