laeformis” These specimens I have not seen at the Kew Her¬ 
barium. But there are specimens from a collection of fungi by 
Ravenel, which came to Cornell University in the “Horace Mann 
Herbarium” from South Carolina, and marked in Ravenel’s 
hand “Dothidea vorax Berk, et Curt., S. C. Rav.” These speci¬ 
mens belong to Balansia hypoxylon and seem to agree in size 
more nearly with the specimens from Texas than with the speci¬ 
mens from Ohio, New York, etc., on Danthonia spicata. The 
pseudosclerotia as well as the stromata are larger than those 
on Danthonia spicata. This may be accounted for by the fact 
that the grass hosts of the Texas as well as the South Carolina 
specimens are stouter than the Danthonia spicata. The stromata 
are larger also than those in the Khasia specimen and this is 
probably what Berkeley refers to when he says “but others on 
Uniola are much larger than the Khasia specimens,” since in 
his description of the Khasia specimens he refers to the stromata 
and not to the pseudosclerotium. “Dothidea pilulaeformis 
B. & C.” seems never to have been described. It may be only 
a manuscript name and therefore is a (C nomen nudemf and can¬ 
not take precedence over Balansia hypoxylon (Pk.). 
The name of the plant and its synonym with emended 
description would therefore be as follows:

Pseudosclerotium curved, or more or less irregular, formed 
in the fruiting axis of the plant, 4-15 mm. long x 1-5 mm. in 
diameter, gray or blackish in color, whitish within and compact 
and somewhat brittle when dry, an abundant development of 
sclerotium elements in which the elements of the host (palae, 
leaves, axis, etc.) are imbedded, some of which are intact, others 
materially disintegrated and deformed. Stromata (fruit bodies) 
black, prominently pulvinate, depressed or rounded, plane or con¬ 
stricted at point of junction with the sclerotium, 1-4 mm. broad x 
1-2 mm. high, surface minutely papillate from the ostiola of the 
perithecia. Perithecia flask-shaped, immersed, 200-400 x 100-200 
fi, wall not very distinct from the stroma but evident from its dif-
