12. Lachnella subochracea (Cooke & Peck) Seaver, comb. nov. 



Peziza subochracea Cooke & Peck, Grevillea 1: 6. 1872. 

 Trichopeziza subochracea Sacc. Syll. Fung. 8: 408. 1889. 



Apothecia sessile, or substipitate, scattered, at first subglo- 

 bose, then expanded and becoming discoid with the margin 

 slightly elevated, yellowish, clothed with white hairs; hymenium 

 ochraceous, nearly plane, or slightly concave with the margin 

 slightly elevated; hairs poorly developed, hyaline; asci clavate, 

 reaching a length of 80 ^ and a diameter of 8 /x; spores partially 

 2-seriate, or irregularly disposed, fusiform, hyaline, 3 X 12-13 ju; 

 paraphyses filiform, or slightly enlarged above. 



On dead stems of Rubus. 



Type locality: Adirondack Mountains.

Although this has been placed in the genus Trichopeziza by 

 Saccardo, the apothecia are not conspicuously hair>^ as in most 

 of the species of the genus. The apothecia are delicately pubes- 

 cent but the hairs poorl}^ developed. 



13. Lachnella fasciculata (Seaver & Waterston) Seaver, comb, 

 nov. 



Dasyscypha fasciculata Seaver & Waterston, Mjcolgia 32; 397. 1940. 



Apothecia thickly gregarious, occurring singly, or more often 

 in dense, fasciculate clumps, several apparently springing from 

 the same base and so closely compact that they appear to be one 

 compound fruit body, short-stipitate, externally clothed with 

 a dense covering of white hairs, the clumps scarcely exceeding 

 1 mm. in diameter, the individual apothecia much less; hy- 

 menium concave, pale-orange; hairs flexuous, hyaline, externally 

 roughened, about 2 ^i in diameter; asci clavate, reaching a length 

 of 35-40 n and a diameter of 4 /z, 8-spored; spores minute, fusoid,
