CLASSIFICATION OF AGARICS 



559. Crepidotus putrigenus I'.. & < . 

 Annals Nat. I list.. L859. 



PILEUS 3-9 fin. broad, Bessile, dimidiate or subreniform, convex 

 to conchate or snbexpanded, densely short villosi tomentose, Lustre 

 dull, whitish or yellowish-whiU . moisl or watery, even on margin 

 when dry. margin incurved. FLESH thickisb behind, white (dry) 

 under the somewhat separable pellicle. GILLS close, broad (width 

 l -."i limes the thickness of the flesh), radiating from the villose 

 basal tubercle, aarrowed in front, rounded-adnate behind, becom- 

 ing crisped <>n drying, edg\ entire. SPORES spherical, smooth, 

 about 6 micr. diam., rusty-fuscous. BASIDIA t-spored. CYS 

 TIDIA none. ODOB rather disagreeable. TASTE tardily some- 

 what nauseous. 



Gregarious <>r imbricate on decaying logs, stumps, etc., of mixed 

 woods. Smith Haven and New Richmond. July to September. 

 Infrequent. 



Whether this species is ;i mere form of C. malachius is hard to 

 determine. The spores are alike, but in our plants the pileus 

 averaged a large size (for a Crepidotus) and its surface was rillose 

 throughout, the villosity becoming denser .-it the base; this may be 

 the resull of luxuriant development. All my collections of C. 

 malachius average smaller, and the pileus is glabrous excepl the 

 base. The gills are somewhat closer than in C. malachius, and T 

 am no1 certain that the pileus is truly hygrophanous. It would 

 seem that the villose, non-hygrophanous, large pileus with margin 

 not striate (dry) and the closer .uills separate it.
