occurring with the Hypomyces was not Gliocladium, as the character- 
istic mucilaginous covering of the heads was absent. 
On account of the characters shown in its conidial stage, and on 
account of the dark-coloured ascospores, it seems doubtful if the 
present Fungus should remain in the genus Eurotiunr, it should 
perhaps, as Winter and Matruchot think, be made the type of a new 
genus.

The present species is remarkable for the small size of the ascospores, 
and also for the manner in which they become exposed at maturity. The 
wall of the perithecium, which is at first sage-green in colour and then 
yellowish, becomes dry and very brittle when the perithecia are quite 
ripe, and completely falls away, exposing the chrome-yellow mass of 
spores. The perithecia occur singly, dotted at intervals on the dung, 
and when crushed under the microscope are seen to be filled with 
innumerable minute free ascospores. Except in the early stages of 
the development of the perithecium it is difficult to find any trace of 
asci, as the walls of the latter deliquesce almost immediately. The 
spores viewed from the front are roundish in outline ; from the side, 
biconvex.
