250 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
4: 168. 1832; Fries, Elenchus Fung. 1: 198. 1828. — Odontia 
sistotremoides (Schw.) Fries, Epicr. 529. 1838. 
Type: a fragment in Herb. Schweinitz and portions in 
Herb. Fries and in Kew Herb. probably. 
Effused, papery, papillate, sulphur-cinereous, 
q 0 the margin byssoid and white; papillae minute, 
A © pilose. 
Fig. 7 Broadly effused here and there on wood. Pa- 
C. sistotre pilae abnormal, minute, occurring in the hy- 
SOR NE menium in seattered distant clusters, with the 
form in all respects of the teeth of Sistotrema and 
clothed with hairs as in T. botryoides. 
—Translation of original description. 
The portion of the type in Herb. Schweinitz is very small 
and not well preserved. I found its spores Saccardo’s mel- 
leus, even, 8 Х 3-4 и, and hyphae of Ше same color, but did 
not detect scattered, clustered granules in the hymenial sur- 
face. The portion preserved may, however, have been from 
the even region between the clustered granules. Fries re- 
ceived a specimen of C. sistotremoides from Schweinitz and 
in *Epierisis! transferred this species to Odontia, placing it 
next to Odontia fimbriata and describing the granules as wart- 
like, minute, dentiform, with apex concolorous and fimbriate. 
I have been on the lookout for a Coniophora which com- 
bines in one specimen both the granular surface described by 
Schweinitz and Fries and the spore characters of the authen- 
tie specimen but have not yet found it. Coniophora olivascens 
has a granular surface to its fructification, but its spores are 
smaller than those of C. sistotremoides, more subglobose in 
form, and its hyphae are hyaline. Schweinitz's statement that 
the papillae are clothed with hairs as in his Hypochnus botry- 
oides is important in showing that he refers to a surface com- 
posed of matted hyphae as seen with a lens in the сазе of 
Hypochnus botryoides and not necessarily to the presence of 
hair-like cystidia protruding from the granules in sections, 
although Fries must have had the latter type of structure in 
mind to lead him to place this species in Odontia between 
O. Barba Jovis and O. fimbriata.
