Hypholoma rugocephalum Atk. 



RUGOSE IIVPHOLOMA 

 Mushrooms, Edible and Poisonous, 2d ed., p. 30, pi. 8, fig.29 



Pilcus fleshy in the center, convex becoming expanded, broadly 

 unibonate, glabrous, irregularly wrinkled or rugose, tawny, the thin 

 margin often curved upward, flesh tinged with yellow ; la- 

 mellae thin, slightly sinuate, adnate, easily seceding from the 

 stem, spotted, purplish black when mature ; stem even, irregular, 

 fleshy, hollow, glabrous, subbulbous, colored like the pileus, paler 

 above the slight filamentous often spore-blackened remnants of 

 the annulus ; spores oval or broadly ellipsoid, inequilateral, pointed 

 at each end, echinulate or minutely tuberculate, 8-1 [ ',)■ long, 

 6-8 // broad, black ; cystidia cylindric, slightly enlarged at the top, 

 hyaline, clustered. 



Pileus 6-10 cm broad ; stem 7-10 cm long, 6-10 mm thick. 



Single or ces])itose. Damp places in woods. July and August. 

 Tompkins and Suft'olk counties. 



This is related to the preceding species from which it may be 

 separated by its wholly glabrous tawny pilcus and its rugosely 

 wrinkled continuous cuticle. Both are allied to Hypholoma 

 velutinum (Pers.) Fr., but may be distinguished from it by 

 the absence of the hygrophanous character and by their broader 

 spores. 



Hypholoma delineatum n. sp. 



DELINEATED IIYPIIOLOIM A 



Pilcus fleshy, thin, convex or nearly plane, often slightly de- 

 pressed in the center, glabrous, rugose or radiately wrinkled, com- 

 monly marked toward and on the margin even when dry with 

 irregular radiating lines or ridges, occasionally wavy or irregular 

 on the margin, brown, tawny brown or reddish brown, often darker 

 in the center, flesh whitish ; lamellae thin, close, adnate, brown 

 becoming blackish brown; stem equal, glabrous, hollow, pallid or 

 colored like the pileus ;. spores even, ellipsoid, not apiculate, 8-10 /' 

 long, 4-6 !'. broad; cystidia scarce, 40-60 ,". long, 16-20 !>. broad. 



Pileus 2.5-5 cm broad; stem 3-5 cm long, 3-6 mm thick.
