white tomentum, all except the protruding papilliform ostiola, 
which are bare. Inner substance of the perithecia, when crushed 
upon the slide, flavovirescent: asci straight or curved, oblong 
sub-fusoid or arcuate, with an occasional shining oil drop in the 
hyaline, rounded apex, ioo x 12/x; sporidia imperfectly biseriate 
or fasciculate, abruptly bent at the lower fourth, at times slight¬ 
er and flexuous in the middle, continuous, hyaline, 40 x 5/x. 
The sporidia are at times furnished with a short (about 6/x) 
acute hyaline tip, at one end or both ends, which appendage may 
also be absent or indistinct. The appendages are mostly seen in 
young sporidia and may become absorbed with age. There are 
small oblong conidia and larger, (40 x 6/x) multiseptate fusiform 
spores, found on the basal threads. The paraphyses are indis¬ 
tinct. 
On the surface of wood (Tilia Americana, “basswood”?) 
under moist bark. Lyndonville, N. Y., October, 1900. This is 
no. 302 in an unpublished paper, Fairman, Pyrenomycetese of 
Orleans County, N. Y. from which this description is extracted, 
in advance. 
Lasiosphaeria sulphurella Sacc. is seated on a sulphur 
colored subiculum and the appendages of the sporidia are 25-30/x 
long. Lasiosphaeria viridicoma (C. & P.) is clothed with a 
dense greenish tomentum and Lasiosphaeria mutabilis has a yel¬ 
lowish-green tomentum which finally turns brown. 
The flavo-virescent color of the crushed perithecia and the 
occasional appendages of the sporidia render our species different 
from the type of L. ovina (Pers.) At first we considered it a 
new species (Lasiosphaeria aureliana Fairman) but Mr. J. B. 
Ellis, the veteran American pyrenomycetologist, to whom speci¬ 
mens were submitted, thought that the color of the crushed peri¬ 
thecia did not entitle it to specific rank. It is to be noted, how¬ 
ever, that in Eutypa flavo-virescens (Hoff.) Tul. and Lecanidion 
indigoticum (C. & P.) Sacc., as well as in Gibberella pulicaris 
(Fr.), the interior color of the fungus is a diagnostic feature. 
Hypoxylon Sassafras has also a dirty or rusty yellow stroma 
which is characteristic. And Mr. Ellis has recently named a 
species of Diatrypella after the yellow stroma, viz., Diatrypella 
xanthostroma E. & E., in the Journal of Mycology, Dec., 1903, 
page 225, and says (loc cit.) “this comes near D. Frostii Pk. 
but the sporidia are longer and the yellow color of the stroma 
inside is different.” 
Some day, therefore, our variety may be raised to the rank 
of a species.

elevations of the surface, through the center of which the com¬ 
pressed ostiola protrude: asci clavate-cylindrical, tapering into
