340, The American Naturalist. [April, 
small patches of yellowish, smooth, waxy hymeium. Spores elliptical, 
hyaline, abundant, 4 x 3% 
PENIOPHORA GLOBIFERA E. & E. On bark of Abies, Canada (Ma- 
coun). Effused, thin, soft when fresh, brittle when dry, cinereous, not 
cracking, closely adnate, margin at first fringed with appressed, silky, 
white hairs, which soon disappear. Cystidia at first globose, soon pro- 
longed above into stout, rough, lanceolate processes, 40-70 x 8-10z, 
hyaline. Spores small, globose, 3» diam. The cystidia are very 
abundant and easily seen with a low power, causing the hymenium to 
appear pubescent. 
ÅSTERELLA PROSOPIDIS E. & E. On living bark of Prosopis duleis 
(Mesquite), near Monterey, Mexico, July, 1896. Dr. B. F.G. Egeling. 
Perithecia gregarious or scattered, superficial, depressed-conical, 2 
mm. diam., with a black, shining subconical ostiolum. Asci clavate- 
oblong, 30-35 x 8-10y, subsessile, 8-spored, with stout linear paraphy- 
ses. Sporidia biseriate, fusoid, hyaline, uniseptate, not constricted, 
subacute, 12-14 x 4—43p. 
CHAETOMIUM SETOSUM E.& E. On damaged hay in stacks, Rooks 
Co., Kansas, August 1896 (Bartholomew, No. 2214). 
Perithecia at first ovate or ovate-conical, or cylindric-conical, becom- 
ing obovate and often flattened above, and contracted below so as to 
appear stipitate, 400-500, high, clothed with straight, erect-spreading, 
smooth, black hairs, 150-200 long and 5-6» thick below, tapering 
above, not branched, with mycelium of reticulate, rough hyphe and 
a fringe of brown, subundulate, short hairs around the base. Asci 
subelliptical, 10-12 x 6-7». Sporidia elliptical, brown, 4-5 x 3-4y, 
and 2-23, thick. 
Differs from Ch. melioloides C. & P.in the simple, smooth hairs that 
clothe the perithecia. 
SoRDARIA VIOLACEA E. & E. On horse dung, Rooks Co., Kansas, 
September 15, 1896 (Bartholomew, No. 2263). 
Perithecia semiemergent, 2-4 confluent, 700-800y diam., slightly de- 
pressed-globose, more or less roughened, with thick walls consisting of 
an outer dark-colored coriaceous sheet lined inside with a thinner, 
violet-colored membrane. Ostiolum hemispherical-papilliform or sub- 
discoid-depressed. Asci clavate-oblong, rounded at both ends, sessile. 
Paraphyses abundant, but indistinct. Sporidia 8 in an ascus, oblong- 
elliptical, becoming opaque, 30-45 x 19-214. The perithecia are 
mostly in confluent groups, but there is no true stroma.
