MONOGRAPH OF THE LABOULBENIACE2E. 



inner also similarly branched, the branches long, tapering to a blunt point, often suffused with 

 brown near the base. The inner appendages commonly arise from two basal cells, the inmost 

 smaller and lower in position, each giving rise to a variable number of branches, usually not 

 more than once branched, hyaline except the outer ones, which are larger and usually suffused 

 with brpwn below. Receptacle elongate. Spores about 55 long. Perithecium, 185 x 50 

 Longest appendages, 370 n. Total length to tip of perithecium, 630 fi. 

 On the upper surface of abdomen of Quedius vernix Lee, Illinois. 



The material on which this species is based is somewhat scanty, only one of the six specimens 

 being mature. In these the insertion-cell, with one exception, does not become wholly black- 

 ened, and seems to give rise on the inner side to a small appendiculate cell. The outmost 

 branch of the outer appendage is deeply suffused with brown and bent outward. The large an- 

 theridia, of the ordinary form, are borne terminally or laterally, singly or in pairs, on short 

 branchlets. The form of the perithecium, especially at its tip, is peculiar, but more abundant 

 material is much needed to clearly define the species.

Amber brown, often tinged with olive. Perithecium straight, but slightly inflated, amber 

 brown or olive ; the tip deeply blackened below the hyaline tips of the lip-cells, which are turned 

 slightly outward. Appendages consisting of an outer and somewhat smaller inner basal cell, 

 the outer producing invariably two branches, one terminal, simple, erect, slightly flexuous ; the 

 other external, sub-terminal, outwardly divergent, long, simple, deeply suffused as a rule near its 

 base ; its first septum blackened and coustricted in many cases. The inner basal cell bears, as a 

 rule, a single long, slender branch on either side, simple or with a short, fertile branchlet at its 

 base ; the antheridia terminal in groups of three to five. Within these primary appendages one 

 to three secondary, simple, elongate appendages are produced by the proliferation of as many 

 cells, which become cut off from the upper inner angle of cell V by oblique septa. Receptacle 

 rather elongate, normal, except for the division and proliferation of cell V, which carries the 

 black insertion-cell out free from the perithecium. Spores, 60-70 x 5.5 /a. Perithecia, 165-170 

 X 55 fi. Longest appendages, 460 \x. Total length to tip of perithecium, 435-540 //..

This species is readily distinguished from all others by the division and proliferation of cell 

 V between the black insertion-cell and the base of the perithecium. In the specimens on E. tro- 

 picum the external branch of the outer appendage is more sub-terminal and not blackened at its 

 base, and the perithecia are somewhat more inflated, but there can be no doubt as to the iden- 

 tity of the different forms. The Japanese host is doubtfully determined, and is very likely a 

 Chlaenius. For the excellent Algerian material I am again indebted to the kindness of Professor 

 Giard.
