Isaria gives rise to peculiar forms in gelatine cultures; for example, 
according to Alfred Giard, reported in the Journal of Mycology, 
Vol. V., p. 174, Isaria destructor assumes the form of Coremium. Core. 
miurn is, however, a genus of Stilbecc very close to Isaria , while Pacliy- 
basium is in the Mucedinece. By the plate-culture methods it is hoped 
that absolutely pure cultures of the Isaria may be obtained, and if 
there is this genetic connection between Pacliybasium and Isaria it may 
then become capable of demonstration. The preceding note is intended 
simply to direct attention to the fact that Pacliybasium has been dis¬ 
tinguished in American habitat, and that it may be looked for in con¬ 
nection with Isaria sphingum , Schw. on gelatine cultures of the latter 
form.

A FEW NEW FUNGI. 
By J. B. Ellis and S. M. Tracy. 
Phyllachora stenostoma, n. s. On leaf of Panicum brizantliemum 
from Africa. Com. Prof. S. M. Tracy. No. 501. Stromata innate, only 
slightly prominent, black, rather indefinitely limited, subelongated, 1-2 
millimeters long, punctate from the slightly prominent hysteriiform os. 
tiola. Ascigerous cavities small, subglobose, numerous. Asci subfas- 
ciculate, sessile, oblong cylindrical, 40-45 by 7-8/*. Sporidia biseriate, 
oblong, 1-septate and slightly constricted at the septum, yellow-brown, 
12-15 by 3-3£/*. Bears a general resemblance to P. graminis , but less 
prominent, sporidia different besides in the narrowly compressed osti- 
lum which resembles a minute Hysterium. 
Fusarium celtidis, n. s. On fruit of Celtis occidentalism Starkville, 
Miss., May, 1890, Tracy, 1333. Sporodochia scattered, erumpent, pul- 
vinate, pale orange, J-l millimeter in diameter. Basidia subfascicu- 
lately branched above, branches erect, 40-60 by 4/4, septate. Oonidia 
fusoid, nearly straight, only the obtusely pointed ends slightly curved, 
5 septate, 40-60 by 4-5/4. 
Cladosporium velutinum, n. s. On Plialaris Canariensis , Stark¬ 
ville, Miss., March, U90. Forming velutinous, olive-brown patches 
£-1 centimeter long, or by confluence longer, slightly thickening and 
distorting the leaf; hyphrn erect, simple, septate, subundulate, pale 
brown, 50-75 by 4-5/4; condia terminal, 8-20 by 4-5/4, 1-3-septate, 
subhyaline, the shorter ones elliptical, the louger ones oblong or cylin¬ 
drical. 
Puccinia apocrypta, n. s. On Asprella Hystrix, Canon City, Colo., 
Tracy, August, 1887. Hypophyllous, sori oval or oblong, occupying 
the entire under surface of the lower leaves and remaining covered in¬ 
definitely by the epidermis ; uredospores oval, epispore thin, minutely
