420 THAXTER. — MONOGRAPH OF THE LABOULBENIACE^ 
ally basally curved, broader at the distal end where it is rather deeply suffused with brown; cell II 
much longer, its lower two thirds often distinctly inflated, deep brown distally, rather abruptly constricted 
lo less than half its greatest diameter, the constricted portion hyaline, the short remaining portion above 
the constriction becoming deep brown, concolorous with the upper portion of the receptacle. Insertion- 
cell normal, oblique, often concave above, the appendages consisting of an outer and an inner basal cell, 
the two producing in all from three to six outgrowths, hyaline, except the first one formed from the outer 
basal ceil which is always external to those subsequently formed and is often divergent, deep brown or 
opaque, the suffusion involving the basal cell which bears it: each branch consists of a single simple 
cylindrical cell the distal portion of which is usually broken off, leaving the deep brown contrasting base.

This species possesses a strangulate habit somewhat similar to that of L. const r icta ; but is otherwise 
quitr different, being most nearly allied to L. coardata. The small protruding lip-cells vary somewhat 
in their conformation, sometimes merely papillate, sometimes slightly spreading, subtended on the inner 
side by a blackish suffusion which is more or less conspicuous. Fig. 20 represents one of the specimens 
from Timor which are regarded as the type forms.

Perithecium short and stout, dark brown and opaque, its upper half free, its contour evenly rounded, 
the small papillate translucent tip turned slightly inward and abruptly differentiated, the lips well defined. 
Receptacle dirty brown finely and obscurely punctate, of the typical form, lighter below, short, stout, cell 
I much narrowed below, cell II very broad, slightly inflated. Insertion-cell normally differentiated, 
broad and black. Basal cells of appendages well developed bearing about eight erect short stout simple 
branches with broad basal constricted blackened septa, their rounded tips slightly exceeding the tip of 
the pentheemm. Spores 70 X 7 p. Perithecia 140-170 X 62 p. Total length to tip of perithecium 
ft; to insertion-cell 250-300 p; greatest width 100 p.

depression of elytra. 
This species, which was found on several specimens growing along a groove of the elytra, is most 
nearlj related to I ,trangufata, but is abundantly distinct in a variety of ways. The material is in un- 
usually good com htion and abundant, and the characters appear to be very constant. Although the 
ueternnnat.on of the host is doubtful, there can be little chance of confusion in the case of so well defined '
