This species is represented by three or four individuals in good condition and is distinguished by 
its antheridial appendage, as well as by the short recurved appendage which subtends the tip of the peri- . 
thechm) on the inner side and appears to arise from the inner lip-cell, which is lateral and overtopped by 
the thiee others which appear to form the whole apex. This appendage may represent the indurated base 
of a triehogyne, the position of which in this genus may be unusual, but I have no available material which 
can determine this point. The terminal spine of the antheridium is long and conspicuous. In one speci- 
men there seem to be only four rows of antheridial cells of five, four, four and three cells each.

Peritlieeium (not fully mature) straw colored, somewhat asymmetrical, almost symmetrically and 
l)iit slightly inflated from base to apex; the tip short, well distinguished; the lip-cells rounded, and slightly 
inflated, forming a knob-like termination, one of them (the inner) protruding in the form of a slight 
tongue-like projection beyond the others: the stalk-cell about as long as the receptacle, from which it 
projects at an angle, being moreover turned at the same time a little to one side. The cells of the recep- 
tacle subequal, lying side by side, the basal one extending to the base of the stalk-cell of the perithecium, 
with which it is in contact. Appendage relatively large, the stalk-cell subtriangular, somewhat larger 
than the basal cell which is wholly overlapped externally by the well defined and distally somewhat in- 
flated marginal cell; the antheridial cells in four tiers of seven, six, five and four cells respectively; the 
discharge-tube long and curved outward. Spores about 36 X 4 p.. Perithccia 165 X 50 p., the" stalk-

The material of this species consists of but two specimens in which the perithecium is not quite 
mature. It cannot, however, be confused with either of the other species in which there are more than 
three rows of antheridial cells.

Receptacle consisting of two superposed cells, the basal cell (in the type) producing two characteristic 
outgrowths, the subbasal giving rise to antheridial appendages and to perithecia. The appendage con- 
surtmg of a stalk-cell followed by a pair of cells with which a small compound antheridium is associated 
distally, the appendage ending in a free cellular extremity above the antheridium. The stalked perithe- 
lium similar to that of Monmcomvces
