248 THAXTER. — MONOGRAPH OF THE LABOULBENIACE^. 
Strictly intercalary in its origin, and its development may be compared to the trichothallic growth of 
certain algse* 
Although from liis observations on the relation of this parasite to its host, Cavara appears to be in- 
cline 1 to regard the Laboulbeniales generally as saprophytes, the occurrence of a number of rhizoidal 
forms seems to render it quite certain that they feed on the juices of the insect which in this, as in a 
majority of cases, are absorbed, without penetration, through the sucker-like foot. 
The genua is closely allied to the succeeding one, from which it differs especially in the possession 
of an antheridium which is compound at maturity.

Basal cell about as long as, or longer than, the rest of the receptacle; the axial series of cells, ex- 
tending to a point nearly opposite the middle of the perithecium; consisting of about six colls, more or 
less; its lowest cell lying above the basal cells of the other two series: the anterior series consisting of 
from four to five cells, the two lower longer, the lowest only occasionally appendiculate ; the posterior 
scries consisting of usually five or six cells, exclusive of the two (rarely single) basal cells of the primary 
appendage which terminates this series. The members of both the anterior and posterior series, with 
the usual exception of the basal cell of the anterior series, cutting off a smaller cell distally and exter- 
nally, which usually cuts off a second small cell; each of these bearing either sterile appendages or an- 
theridia. Antheridia relatively small, flask-shaped, the venters evenly inflated and evenly curved to 
the narrow Decks which are about half as long as the venters. Secondary and primary appendages 
hyaline, or suffused with brown, simple, mostly inflated, short. Perithecium somewhat asymmetrical, 
its cuter margin and distal half tapering to the somewhat irregular blunt, or truncate, hardly differen- 
tiated tip. Perithecium 40-50 X 18-22 ft Spores 28 X 2.5 ft. Total length to tip of perithecium, 
avenge 150 /t, maximum 200 /*. Antheridia about 12 X 4 «.

This species is said to be abundant in the localities where it has been found, parasitizing a majority 
of the individuals in certain nests of its host. I have thus far been unsuccessful in attempting to find 
it in this country, where it seems to be replaced by the curious little Laboulbenia Formimmm. In ex- 
cases 
secondary pentheoa may arise from one or more cells of the receptacle below, as is the case in Peyrit- 
schiella and in other genera.

Receptacle consisting of a basal and subbasal cell, surmounted by two parallel series of cells of in- 
externally; one 
of the series ; ending in a perithecium, the other terminated t • the primary appendage. Appendages 
of the same type as those of Rtckia and Peyritschiella. Antheridia at maturity tenninal on a unicellular 
branch, becoming quite free in a compact group. 
This genus is distinguished from Uickia by its ultimately free antheridial cells which are apparently
