SPH ARIA CALLISTA B. & C. 
Dead branches of Cornus alternifolia. Buffalo. Clin- 
fon. Sandlake. Autumn and spring. 
I do not know that any description of this species has 
been published, but our specimens agree with those repre- 
senting it in Ravenel’s Hungi Hasiccati Caroliniani. The 
perithecia become pezizoid-collapsed, and the asci contain 
numerous small curved colorless spores, as in some species 
of Nectria. 
SPH.ZRIA PHEZOSTROMOIDES 72. Sp. 
Conidia. Flocci simple or branched, septate, some of 
them nodose, globosely inflated at the apex ; spores apical, 
oblong, obtuse, uniseptate, centrally constricted, colored, 
.0005’-.0007’ long. 
Ascophore. Perithecia gregarious, minute, globose, then 
collapsing, rugulose, seated on a black subiculum ; asci 
subfusiform ; spores crowded, subfusiform or cylindrical, 
slightly curved, triseptate, colored, .001’ long, the terminal 
cells colorless, the others sometimes nucleate. 
Dead branches lying on the ground. North Greenbush. 
September. (Plate 2, figs. 30-365.) 
This plant appears to be the American analogue of 8S. 
pheostroma, from which it scarcely differs except in its 
shorter spores and uniseptate conidia. So closely does the 
subiculum of our plaut resemble Cladotrichui triseptatum, 
that it might readily be taken for a Cladotrichum with uni- 
septate spores. 
SPHARIA SUBCORTICALIS 2. Sp. 
Perithecia rather large, thin, sometimes collapsed, black, 
involved in a dense blackish-brown tomentum which is some- 
times confluent, forming a subiculum; spores oblong 
colorless, .0003’ long.

Dead bark of water beech, Carpinus Americana. North 
Greenbush. June. 
When the perithecia are crowded the tomentum runs 
together forming a subiculum, when scattered, it surrounds 
each separately. They are seated on the inner bark and are 
entirely concealed by the epidermis. When this is torn 
away the perithecia usually come off with it. The specific
