Lower surface of living fronds of Freris aguilina. California. 
Prof. M. A. Howe. 
This fungus imitates Phydlachora pteridis in habitat and general 
appearance, and might easily be supposed to be the conidial state 
of it. The lines of the perithecia are more narrow and less prom- 
inent. The masses of discharged spores are rather large and very 
numerous and partly conceal the black perithecia beneath them. 
CAEOMA ABERRANS. Pustules suborbicular, slightly elevated, 
.5 to 1 line broad, at first covered by a whitish membrane which 
finally disappears revealing the mass of orange-yellow spores; 
spores subglobose or elliptical, smooth or nearly so, .0007 to .0009 
* in. long. 
Bark of living alder. Newfoundland. May. Waghorne. 
This fungus is peculiar in its habitat. The spores do not easily 
separate from each other, but possibly this is due in some measure 
to immaturity. 
ASPERGILLUS SUBGRISEUS. Grayish; sterile hyphae creeping; 
fertile erect, continuous, simple, .0003 in. thick, terminating above 
in an inflated subglobose vesicle .0012 to .0016 in. broad; sterig- 
mata none or obsolete; spores globose, .00016 in. broad. 
On Corticium amorphum. Newfoundland. Waghorne. 
This species is separated from the related A. griseus by its 
larger spores, continuous fertile hyphae and by the absence of 
distinct sterigmata. 
LerroGLossum LATuM. Club 3 to 6 lines long, nearly or quite 
as broad, soft when moist, rather fragile when dry, compressed 
and somewhat irregular, black; stem about as long as the club, 
black ; asci clavate-cylindrical, .0045 to .005 in. long, about .0005 
broad, 8-spored; spores crowded in the ascus, oblong or cylindri- 
cal, straight or slightly curved, continuous, obtuse, colorless, .OO! 
to .0o16 in. long, .0002 to .00024 broad; paraphyses colored, 
thickened at the top and sometimes recurved. 
Sandy soil. Labrador. September. Waghorne. 
A species very peculiar in its broad compressed club. The 
colored paraphyses are conspicuous under the microscope. They 
project slightly above the surface of the receptacle and give it a 
soft, almost velvety appearance. : 
VaLsa BREVIS. Pustules numerous, rather prominent, peri- 
thecia 10 to 20 or more in a pustule, nestling in the inner bark; 
ostiola even, black, barely emerging from and dotting or oblitera-
