DASYSCYPHA. 345 



A very minute and delicate species, and when examined 

 after being dried, the long, delicate hairs, said to be present 

 in the living state, are not apparent. Phillips gives the 

 spore measurements as 12 X 2 jx, which are certainly much 

 larger than the specimen I have examined, which was sent 

 by Roberge to Berkeley. 



B. Externally coloured. 

 f Paraphyses lanceolate. 



* Disc brownish, reddish, or buff. 



Dasyscypha horridula. Mass. 



Gregarious or scattered, sessile but attached by a point 

 only, hemispherical then expanded, about § mm. across ; 

 excipulum thin and delicate, parenchymatous, cells small, 

 slightly elongated radially ; densely pilose externally, hairs 

 somewhat spreading, simple or rarely with 1-2 short 

 branches originating at right angles and near the apex, 

 wall thin, rather closely septate, cylindrical, smooth, some- 

 times wavy ; bright brown, becoming colourless towards 

 the tip, 80-150 X 5-6 /x ; disc pallid ; asci narrowly clavate, 

 8-spored; spores linear-fusiform, hyaline, smooth, distinctly 

 1-septate at maturity, 15-20 x 1*5 \x, irregularly biseriate; 

 paraphyses lanceolate, apex acute, longer than the asci, 

 about 4 fx broad at the widest part, hyaline.

Very close to D. canescens, under which species the two 

 are contrasted. 



Dasyscypha fragariastri. Mass. 

 Gregarious, stipitate, firm, cyathiform, faint purplish-red,
