70 TWENTY-EIGHTH REPORT ON THE STATE MUSEUM. 
When moist the perithecium gaps widely, revealing the 
conspicuous white disk. This and the different habit dis- 
tinguish the species from Xyloma Ledi. 
AILOGRAPHUM SUBCONFLUENS 7. Sp. 
Perithecia, small, numerous, thin, scattered, or subcon- 
fluent ; orbicular, elliptical or elongated, black ; asci oblong ; 
spores oblong-clavate, hyaline, .003’-.004’ long. 
Dead stems of herbs. North Greenbush. June. 
This appears to the naked eye much like some Leptos- 
troma. 
TORRUBIA CLAVULATA Schw. 
On dead scale insects of black-ash branches. Lake Pleas- 
ant. August. 
Schweinitz describes his Spheria clavulata as growing on 
a fibrillose-membranaceous shield-shaped subiculum which 
adheres closely to the bark of living branches of oak trees, 
Quercus palustris and Q. coccinea. Our plant grows on the 
flattened discolored or blackened bodies of a scale insect 
found on living branches of Fravinus sambucifolia. Not- 
withstanding this difference in habitat and a slight discrep- 
ancy in the arrangement of the perithecia, the species is so 
remarkable and so well characterized that I cannot believe 
our plant to be specifically distinct. It is the smallest Tor- 
rubia known to me, and does not well agree with the gen- 
eric character. It occurs on young and half grown as well 
as on full grown insects, but I have not been able to deter- 
ee whether it attacks the insect while living or only after 
eath. 
TORRUBIA SUPERFICIALIS 7 Sp. 
Slender, about 1’ high, smooth, brown, the sterile apex 
eradually tapering to a point; perithecia crowded, super- 
ficial, subglobose, blackish-brown, sometimes collapsed, 
with a small papilliform ostiolum; ascicylindrical ; spores 
long, slender, filiform. 
Under hemlock trees on buried larve. Northville. Au-

~ Related to and intermediate between 7. Raveneléi and T. 
Carolinensis. The stem of the plant is about equal in 
length to the club or perithecia-bearing part. The perithe- 
cia are more loosely placed at the extremities of the club, 
thereby giving it a subfusiform shape. The spores are more 
slender than those of 7 Carolinensis but the plant itself is 
less elongated and slender.
