“Chorioactis Geaster. ( Urnula Geaster Peck, Reg. Rep. 
46:39. 1903.) Finally we come to the species which was called 
by Peck Urnula Geaster, and which, since it is not an Urnula, 
I propose to call Chorioactis. This is a very large leathery fungus 
from 4-7 cm. in diameter, narrowed to a stem about 3 cm. long 
and 1-1.5 thick. The apothecium splits into 4-6 rays, giving the 
plant an appearance very similar to a Geaster, so that Peck’s spe¬ 
cific name is an appropriate one. Both disc and stem are covered 
on the outside with a dense tomentum of soft brown hairs. The 
thickness of the apothecium is a striking characteristic; it some¬ 
times reaches 2.5 m. The outer layer of the apothecium is dark 
brown, the hymenium and flesh yellowish white; the asci are very 
large, 670 fx long; the spores are 49-60 /x long by 12-16 jx wide. 
The Geaster- like appearance of this fungus, the tough, leathery 
texture, the thickness of the disc, and the velvety tomentum which 
clothes the whole surface make of it an exceptionally characteristic 
and easily distinguishable genus and species. That it is not an 
Urnula seems to me just as evident from its external appearance 
as from examination of its tissues. A comparison of internal 
characters shows, however, that there is no possible relation with 
Urnula Craterium. The tissue is made up wholly of large 
parenchymatous cells; those of the excipulum averaging 34 ^ in 
diameter, those of the hypothecium 10-14 f x - The relative size 
of the cross sections of the various forms discussed can be seen 
from the fact that the sections of Chorioactis Geaster are magnified 
only thirty-five times, while all the others were magnified about 
two hundred times.” [Ascomycetae.]
