Comophorella atrocinerea Karsten, Finl. Basidsv. 438. 1889. 
Type: type distribution in de Thiimen, Мус. Univ., 1806. 
Fructification effused, byssoid-membra- 
naceous, adnate, drying sepia, the margin 
somewhat mucedinous and paler, some- 
times whitish; hymenium even; in struc- 
ture 250-500 и thick, composed of loosely 
interwoven, nearly black, rigid, even 
hyphae 314-5 и in diameter, not nodose- 
septate, not incrusted; cystidia incrusted, 
co o 
septate, 9-15 шіп diameter, emerging up 
to 60 и; spores colored, even, 9-10 41/5—6 д. 
д | Fructifications 1—2 em. long, 1 em. broad,

oa esl Тһе Louisiana collection agrees closely 
with the type distribution from Finland in 
all respects except in having slightly broader spores, which 
are бу in diameter in the American specimen and usually 
about 4% u in the type, although published by Karsten as 
5-6 и. This species is very distinct by its firm, rigid, and 
nearly black hyphae. It is strange that two specimens of 
so similar and marked structure occur at such widely distant 
loealities without intermediate stations.
