334 THAXTER. MONOGRAPH OF THE LABOULBENIACE.E. 
On the inferior thorax of Chlccnius biguttatus Motsch., Japan; Berlin Museum, No. 923. 
Allied to /,. hvmilis, but differing in its appendages, and in the conformation of the spreading tip of 
its perithelium which is itself differently shaped, and differently related to the insertion-cell.

Rather slender, nearly uniform dirty olivaceous. Perithecia relatively large, straight, erect, the 
outer margin nearly straight to the lips, or slightly convex; the tip not well distinguished, with darker 
shades below the rather coarse, pale, outwardly oblique lips. Basal cell of the receptacle relatively large, 
somewhat paler; the cells above it darker, and transversely, rather coarsely, striate-punctate especially 
cell 11 ; 11 III separated from cell II by a short horizontal septum; cell VI separated from cells II and 
III by oblique septa; the anterior margin of the receptacle slightly convex, the posterior strongly diver- 
gent above cell II. Insertion-cell relatively narrow and thick, the outer appendage short, simple, taper- 
ing, four to five-celled, slightly divergent above the basal cell, which is rather long, irregular and paler; 
the subbasa! cell separated by a more or less distinctly oblique septum, where the appendage is slightly 
geniculate; the inner appendage erect, simple, or the small basal cell producing two pale, short, few-celled, 
simple branches. Spores about 50 X 5 /£. Perithecia 100-125 X 30 //. Receptacle about 185 ;i. Ap- 
pendages 60-75 /i. Total length to tip of perithecium 250-275 fi.

This species, although insignificant, is well distinguished by its feebly developed appendages, the 
form of its perithecium and the conspicuous striation of cell II. It seems to be as nearly allied to Z. Cras- 
pidophori and L. exigun as to any other species, but could hardly be confused with either. The form on 
C. cyanireps is taken as the type and illustrated in fig. 10.

Proc. Am. Acad. Arts and Sci., Vol. XXXV, p. 162. December, 1899. 
Perithecium wholly free, rather deeply suffused with smoky or reddish brown, subclavatc or almost 
symmetrically inflated, tapering from the middle to the nearly symmetrical, or externally slightly oblique 
blunt tip, the basal wall-cells contracted to form a long slender neck-like subhyaline stalk. Receptacle 
abnormally developed, cells I and II nearly equal, cells III to V forming a stalk which is deeply suffused 
with blackish brown especially externally, and rather coarsely punctate in the darker areas, of equal diam- 
eter throughout and quite free, except at its very base, from the rest of the receptacle: cell IV larger than 
cell III, cell V small and separated by an oblique septum; cell II often somewhat suffused and distinctly 
finely punctate; cell I about as long as cell II, and faintly punctate above; cell VII and the basal cell's 
of the perithecium very small. Outer appendage consisting of a basal cell deeply blackened externally, 
and bearing a long slender simple branch, distally hyaline, more or less suffused with smoky brown to- 
ward the hase: the inner appendage consisting of a basal cell about half as long as that of the outer 
producing a single branch on either side which may be once or twice branched, the antheridia borne 
UM.ally m twos or threes on short branchlets near the base. Spore 110 X 7 p. Perithecia exclusive of 
stalky 270-340 X 65 /<; including stalk 340-430 fL Total length to tip of perithecium 650-800 /<; to
