COPRINUS FLOS-LACTUS sp. nov. 
Solitariis vel agregatis ; pileo hemispherico dein plano-ex- 
panso, 2.5 ad 4 cm lato, brunneo-flos-lacto, plicato-sulcato, flocce 
sparcis praeditis, margine integro vel late fisso; lamellis griseis 
dein nigris, a stipite leviter adherentibus, dein libris, 3 mm latis, 
obtusis; stipite tenaci cylindraceo, 2.5 ad 3.5 cm longo, 3 ad 4 
mm crasso, lucidulo-albo, cavo, fibrilloso, basi incrassato; sporis 
ovoideo-pyriformibus, atro-brunneis, levibus, 3.5 ad 5.5 p latis, 
7.5 ad 11.5 p longis, vacuolatis; basidiis clavatis, 9 p latis, 23 p 
longis; sterigmatibus 4 p longis. 
Plants solitary to gregarious. Pileus hemispheric, with age 
becoming flatly expanded, 2.5 to 4 cm in diameter, a light creamy 
brown in color, remanants of a universal veil remain as a few 
scattered floccose scales, sulcate, the margin entire at first but 
splitting later. While young the cap is crisp and brittle, crum- 
bling on being handled, and on becoming mature tends more 
toward drying up than deliquescing. Lamellae pale-gray at 
first, later changing through grayish-brown to dark brownish- 
black and black. The darkening begins first at the margin of 
the pileus and slowly advances toward the center, edge of the 
gills usually remaining conspicuously white even at maturity, 
slightly adherent to the stipe at first then becoming free after 
the pileus has become expanded, 3 mm broad at the broadest part, 
somewhat obtuse at either end. Stipe cylindrical and of an 
equal diameter throughout, 2.5 to 3.5 cm long, 3 to 4 mm thick, 
shining white, hollow, fibrillose, with an unthickened base. 
Spores from ovoid to pyriform, very dark brown at maturity,
