234 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
spores 9-11X3—4 и; basidia simple, with 2 sterigmata; basid- 
iospores hyaline, even, subglobose, 3343-354 ш; cystidia 
septate, cylindric, more or less granule-incrusted, hyaline, 
6-9 џ in diameter, protruding 20-60 y, about 1-3 to a granule 
at the apex. 
Fig. 1. О. Sacchari. Section of granule of fructification, 
showing young basidia and incrusted cystidium, 0; basidia with 
two sterigmata, b; basidiospores, в; hyphae and lateral spores 
from interior of fructification, n. 855. 
Fructifications 3-5 em. in diameter. 
On dead sheath bases and cane trash of sugar cane. Cuba 
and Porto Rico. April, July, and August—the best specimen 
in August. 
When specimens of this species were originally received 
from the Cuban Experiment Station in 1905, I was disposed 
to place the species in the genus Peniophora, because the hy- 
menium was so nearly even in the dried condition. Collections 
recently received from Mr. Stevenson, Rio Piedras Experi- 
ment Station, show granules distinctly visible in the dry fruc- 
tification. In all specimens granules show distinctly in sec- 
tions prepared for microscopical examination, and each gran- 
ule has one or more cystidia emerging from its apex, hence 
this species is a true Odontia. The noteworthy characters of 
О. Sacchari are its minutely granular hymenium, which is 
sometimes nearly even under a lens, the numerous spores
