 Fxsicc. Fckl. F. Rh. 950. Ell. N. A. F. 893. Roum. F. Gall. 793. 



Perithecia mostly gregarious, on a thin subiculum of brown, creep- 

 ing, broadly effused hyphas, globose or subovate, about J mm. or a 

 little more in diain., tubercular-roughened, dull black, clothed with 

 scattered, brownish-black, spreading hairs. Texture coriaceo-membra- 

 naceous. Asci cylindrical, mostly narrowed above, p. sp. 150 x 12-15 /i, 

 8-spored. Sporidia biseriate, vermiform-cylindrical, narrower and 

 curved below, hyaline, nucleate, becoming yellowish and more or less 

 distinctly 5-7-septate, 55-60 x 5-6 /i. 



On rotten wood, Canada, Carolina, Louisiana, New Jersey and 

 west to Iowa and Montana. 



The Louisiana specc. have the head of the sporida ovate-elliptical, 

 subolivaceous, but not brown, 8-10 /jl thick. Sporidia about 55 ji long.

Lasiosphceria Rhacodium, Ces. & De Not. Schema, p. 55. 

 Exsicc. Fckl. F. Rh. 951. Rab. Herb. Myc. 649. id. F. Fur. 829. Sydow. M. March 381. 



Perithecia gregarious, \ mm. diam., coriaceo-membranaceous, 

 seated on a felt-like subiculum of black, branching, interwoven hyphas, 

 clothed with spreading, black hairs. Asci stipitate, fusoid-clavate, 

 about 180 [x long by 10-15// thick. Sporidia biseriate, cylindrical, 

 curved below, hyaline or yellowish, faintly septate, 50-60 x 4-6 [i. 



On rotten wood, Carolina to Michigan and Canada. 



The orthography "Rhacodium" is doubtless etymologically cor- 

 rect, though Persoon wrote Racodium. This is scarcely more than a 

 form of L. hirsuta, Fr., with the subiculum more highly developed.
