10 Rhodora [JANUARY 
a typical tremelline structure, with hyphae embedded in jelly and 
basidia divided vertically into four parts. The spores, which were 
not very abundant in specimens examined, were broadly allantoid 
or broadly elliptic with one side flattened and the lower part apiculate 
on the inner side. They measured 8 p-10  X 5 w-6 u. The germi- 
nation could not be studied. 
When fresh and in good condition the fungus is very striking and 
does not resemble any other of our Tremellinaceae known tome. An 
examination of the literature led me at first to think that the species 
was Tremella fucijormis Berk. from the Amazon, described in Hooker's 
Jour. Bot. 1856, p. 277 and later recorded from Cuba in Jour. Linn. 
Soc. 10, 340, 1869. A later examination, however, convinced me 
that the fungus is the same as that described by Berkeley under the 
name of Corticium tremellinum В. & Rav., var. reticulatum Berk. in 
Grevillea 1, 180, June, 1873. In explanation of my reasons for 
forming this opinion it is necessary to refer to certain specimens which 
I have examined. 
In Herb. Curtis are four specimens marked Corticium tremellinum 
including the variety reticulatum. The first, from the collection 
cited in Grevillea, is marked “In caudice Filicis? Cotoosa Springs, 
Ga., 1853. Ravenel (1754)”; the second is marked “Ad basin culm. 
et gramin., Sept. 1855. Ala. Super. Peters (897)"; the third is 
marked “ (6393) Wisconsin, coll. Lapham. Sprague (996)." The 
three specimens above named are all called C. tremellinum, the fourth 
is marked “Corticium reticulatum. Damp naked earth under shrub- 
bery in a garden, Penna., 1851. Michener (1212) (3942)," the collection 
cited in Grevillea under the variety reticulatum. There are besides 
two duplicate specimens from Michener inserted in Herb. Curtis and 
all three specimens are identical in structure. 
'The specimen of Lapham from Wisconsin may be excluded from 
consideration, since it shows no characteristic structure and is a 
mixture of different things entangled in hyphae which cannot be 
referred to any particular genus. In the next place, an examination 
of the other three specimens shows that none of them belongs to the 
genus Corticium but that all are Tremellinaceae, since they have the 
characteristic 4-parted basidia. The specimen from Cotoosa Springs 
(Ravenel) and that from Alabama (Peters) appear to be the same 
species, but the so-called variety, Pennsylvania (Michener), is quite 
different. "Тһе former are more or less bullate masses, wrinkled and
