species seems to be 
host, which is the smallest insect thus far known to be infested by Laboulbeniales. It varies very consid- 
erably in the amount of secondary growth of its receptacle, the extremes in this respect being illustrated 
by figs. 15-17. The host i> often very abundant in piles of moist vegetable refuse.

Receptacle indeterminate, consisting of numerous cells superposed singly, or in tiers of two or three 
cells each, ending distally in an appendiculate portion not clearly distinguished from the receptacle, and 
a solitary perithecium, the two related to one another somewhat as the corresponding structures are re- 
lated in Lahoulbenia. (Antheridia simple and borne free on the short appendages?). 
In the absence of any exact knowledge as to the antheridia, it is not possible to define this type very 
precisely, although its general characters are such as to distinguish it very clearly from other genera un- 
less 
Th 
antheridia seem to be evanescent, and in even the youngest specimens, in which the perithecium is quite 
undeveloped, what appear to be the remains of them, only, have been seen. The appendages are not 
well developed and are irregular in their origin; the primary "appendage" from which they arise recalling 
thai of Ceratomyces, although less definitely differentiated and varying considerably. It seems safe to 
a tome from sn examination of the material available that the antheridia are simple and free, but it is 
to be hoped that Kuropean observers may obtain fresh material of the young conditions of M. Dyschirii, 
on various species of Dyschirius, in order definitely to determine this point. 
n » i* » s difficult to judge of the nearest relationships of the genus, but the 
ch;n-acte,- of its receptacle would appear to ally it to Ectelnomyces, although the primary appendage is 
clearly distinguished in this genus and the perithecium is different in character.

Rather rich amber-brown, the receptacle consisting of from eight to twenty-three superposed cells, 
the upper ones rarely divided longitudinally, the distal cell lying between several, usually three, smaller 
«vlls which become separated from it on either side, and which, together with its base, are united to the 
be of the pentheemm; while above it, and separated from it by a thin dark insertion, a cellular base
