BURT—ODONTIA SACCHARI AND О. SACCHARICOLA 235 
among the hyphae between the hymenium and the substratum, 
and the basidia with two sterigmata. The spores of the inte- 
rior of the fructification are borne singly on short lateral out- 
growths along the hyphae of the fructification, as shown in 
the accompanying figure. Only two basidiospores have been 
found, one of which was attached to the sterigma. Deeply 
staining basidia form a normal hymenium but are apparently 
immature, for only a very few basidia show sterigmata yet.
