CLASSIFICATION OP AGARICS 581 



Solitary <>r scattered. <>n low, wet, itiossj or swamps ground, 

 on leaf mold, etc., in hemlock regions. Ba.i view. South Qav< 

 New Richmond. July-September. Infrequent. 



This species is known by ilif covering of the cap and stem, its 

 color and the very large tuberculate spores. It is very variable 

 and was considered an Entoloma i>\ Peck, who first described the 

 form with the thin, striate pileus whose surface is onlj granular- 

 furfuraceous or mixed with the characteristic hairs. Later Atkinson 

 described the form in which the hairy covering is more highly 

 developed, often as if matted, as Solaneu nodospora. I have found 

 the two forms in differenl parts of the siatr ami consider them 

 variations oi the same plant. The trama of the pi I en- is two layered, 

 the Layers being separated by a dark line of narrow hyphae. A form 

 occurs in frondose woods, of which the hair-like fibrils of the Btem 

 arc almost ferruginous. The gills of V. dysthales remain dark 

 grayish-brown a long time and hence it is easily mistaken lor an 

 Inocvhe: at Length, however, they are somewhat colored by the 

 rather bright spores. It seems that in very moisl situations the 

 cap is less hairy scaly and then striate, especially when more fully 

 expanded. The size of the basidia varies as the plant slowly ma- 

 tures and the cystidia seem to take on a different shape in ; _
