globose free branches, 10-15^ in diameter and also echinulate, 

 margin of pileus with free clavate branches in the form of a 

 fringe. Cells of the trabeculae 25-30 X 6-10 /x. Hymenium 

 plane or with few short, narrow gills. Gills when present nar- 

 rowed at each end, not reaching the stipe. In the plant observed 

 8-10 long lamellae, 4-6 intermediate ones much shorter. Sub- 

 hymenium loosely branched, obovate cells arising from the tra- 

 beculae and terminating in the basidia, or in the forms with 

 lamellae arising from a rudimentary trama in the lamella. 

 Basidia short clavate, abruptly narrowed into a pedicel, 9-12 X 

 6-9 /x, 4-spored. Spores obovate-oblong, elliptical, proximal 

 end pointed, 6-8 X 3-4 /a, hyaline, smooth, granular. Stipe 

 thread-like, with scattered hairs bearing a short echinulate cell 

 on the end. Base of stipe only slightly broadened. 



Eomycenella is related to Discocyphella^ P. Hennings, but differs in the 

 dissolving hymenium and the fact that the pileus is not gelatinous nor the 

 stem horny. From Cyniatella^ Patouillard (placed with Agaricaccae) it 

 differs in the trabecular pileus and the dissolving hymenium ; and from 

 Gloeocephala*' (Clavariaceae) Massee, which has one-spored basidia. The 

 latter should be placed in the Thelephoraceae.

II. EOTERFEZIA, THE TYPE OF A NEW GENUS AND FAMILY OF 



ELAFHOMYCETES. 



This fungus appeared as a parasite on Sordaria grown in the 



F 



laboratory in the spring of 1897. Cow dung which had been 

 lying on the ground all winter was collected early in the spring 

 of 1897 in a pasture field just beyond Buttermilk creek, near 

 Ithaca, N. Y. This was placed in a moist chamber and in the 

 course of a few weeks the Sordaria made its appearance. The 

 species of Sordaria was not determined. After the cultures had 

 been kept a week or so longer, there appeared on the perithecia 

 of Sordaria minute white, knot-like protuberances which were 

 smaller than the perithecia and stood out in strong contrast to the 

 dark brown wall of the host. These minute bodies, subglobose 

 or kidney shaped, were nearly smooth, possessing a few scatter- 

 ing free threads arising from the surface, and their texture was 

 soft and fleshy.
