Receptacle consisting of two small superposed colls from Trliich arise the single pcrilhocinni 
and the single antheridial api)endage. Perithecium largo, pointed, borne on a single stnlk-cell 
surmounted by three basal cells. Antheridial appendage consisting of a basal cell surmounted 
by a terminal body, the antlicridium, entirely divided by anas'toniosin.-r sqifa into numerous small 
cells, and furnished with a short lateral projection, b.gcther wilh a sub-terminal short spine- 
jrn a rounded base. Asci four-sporcd, arising from eight ascoo-cnic cells.

Spores once septate. 
Owing to the fact that no fresh material of this gCTius, or any of its younger stages have 
been examined, there arc numerous poinfs connected with it which need to bo made clear. 
Unlike the succeeding genus, Cantharomyccs, its nearest ally, the antheridium ai)pcars to be ter- 
minal, not lateral. No discharge of anthcrozoids was observed in any of the specimens cxammcd, 
and it is uncertain how and where such discharge takes place. Certainly not through the ter- 
minal spine-like process, so characteristic in the genus, whicii is undoubtedly a peculiarly 
modified sterile cell, perhaps the remains of the original terminal spore segment. It seems 
more probable that a lateral projection prominent in some specimens (at the right in fig. 3) rep- 
resents the point of discharge; but what relation the irregularly honeycomb-like mass of cells 
composing the body of the antheridium bears to this projection, or how many of these cells are 
really spermatic, it is impossible to say. Examined with an immersion, indications of a central 
cavity, containing small i-oundish bodies, probably antherozoids, and extending upward and out- 
ward to the external projection previously mentioned, may be made out, though not with sulli- 
cient definiteness to enable one to figure these structures. From analogy with related genera, 
however, there can be little doubt that some such arrangement of the spermatic cells about a 
common cavity must exist. 
The perithecium is remarkable from the fact tliat it contains eight ascogcnic cells arranged 
symmetrically in four pairs, a condition only occurring in this and, perhaps, in the succeeding 
genus. 
The hosts of these curious little forms all belong to the staphylinid genus Bledius, common 
further south along the sandy or gravelly margins of streams, especially in shady places, where 
they may be found under stones or burrowing in the sand. The only material examined has 
been that contained in the collection of the Museum of Comparative Zoology at Cambridge.

Pcrithecia olive brown, tapering abruptly to the small blunt apex, greatly inflated exter- 
nally, intei-nally nearly straight ; a distinct prominence, the base of the old trichogync, usually 
visible on its anterior face below the apex, its basal cells short, wider than long, more or less 
suffused with olive brown, the stalk-cell stout, sub-triangular, hyaline. Receptacle small ; its 
basal cell nearly hyaline, more than twice as large as the sub-basal, which is intensely blackened
