EXTRA-AMERICAN LABOULBENIALES. 705 



separated, hardly longer than broad; cell V long and narrow, reaching 

 a little lower than the inner margin of cell IX. Outer appendage 

 rather stout, the three lower cells somewhat similar, longer than broad, 

 slightly constricted at the septa; the basal shorter, deep olive brown, 

 concolorous with the clearly defined insertion-cell; the distal part of 

 the appendage slightly soiled with brown, bearing a few irregular 

 hyaline branches: basal cell of the inner appendage very small, 

 hyaline above, and producing right and left branches, the basal cells 

 of which are rather long, bearing one or two long slightly brownish 

 antheridia and a few hyaline branchlets; both appendages and their 

 branches appressed and curved against the perithecium, the branch- 

 lets reaching above its tip. Perithecium straight, its axis sometimes 

 slightly divergent, the two lower tiers of wall-cells deeper olive brown, 

 faintly granular-punctate; the diA'isions marked by rather clearly 

 distinguished lines; the venter but slightly inflated, tapering to the 

 blunt apex; the coarse lips nearly hyaline, the inner more prominent 

 ■and subtended by a darker blackish area. Perithecium 60-65 X 22 /x. 

 Appendages 70 fx. Total length 120-140 /x, the bullions foot 16 /jl.

Laboulbenia porrigens nov. sp. 



Basal cell relatively short, bent to one side, more or less swollen or 

 distorted, bearing the foot on its under side, somewhat paler than the 

 subbasal cell which is stained with pale dirty brownish, and punctate- 

 roughened, almost its whole distal margin obliquely separated from 

 cell VI. Cells III-V replaced by a single cell somewhat more deeply 

 suffused, and more closely punctate than the subbasal, of nearly uni- 

 form diameter, and two to three times as long as broad, and pro- 

 jecting outward, almost at right angles, free from the receptacle; this 

 finger-like projection bearing the appendage and insertion-cell at its 

 extremity. Insertion-cell well developed, deep olive brown, concolor- 

 ous with the basal cells of the appendages. Axis of the outer append- 

 age consisting of two cells ; the upper longer and much paler, bearing 

 distally usually two stout branches, which branch successively about 

 five times; the divisions above the second perfectly hyaline, slender; 

 the ultimate branchlets tending to bend downward, and to produce 

 rounded tooth-like projections from their lower surfaces, which are 

 more or less irregular: basal cell of the inner appendage less than half
