of ;i slightly .smaller basal cell bearing a branch on either side, the basal cell of each branch shorter, and 
giving ris<- typically to paired branchlels from the basal cells of which the large, long, slender deep red- 
brown antheridia are produced in pairs. Perithecia 400-7G0 p. Total length to tip of perithecium, 
average 550 /<; longest over 1 mm.; average breadth 50 //. Appendages, longest 375 pi.

A very distinct species, readily recognized by its long large slender dark paired antheridia, its slender 
■ oarse tipped perithecium, etc. It docs not appear to be very closely allied to any described species, unless

IVritliccium relatively large, as long or longer than the receptacle, straight, erect, almost wholly free, 
rather dark dull brown; the outer margin distally converging rather abruptly in an almost straight line 
to the apex; one (the right) of the lateral lip-cells prolonged obliquely inward and upward to form a large 
tooth-like projection. The receptacle relatively short and stout, the basal cell longer, hyaline and con- 
trasting, except distally, where it is involved in the general uniform dark dirty olive-brown suffusion of 
the rest of the receptacle, the cells of which are short and broad, punctate, hardly distinguishable. The 
insertion-cell thick, black, rather narrow, the basal cell of the outer appendage short and stout, bearing 
distally an inner and an outer branch, the basal cell of the outer bearing two branches, the black con- 
trasting constricted base, only, of the outer, persisting; the appendages otherwise hyaline, stout, tapering 
li-htly; the basal cell of the inner appendage very small, roundish, bearing a branch on either side with 
ungle antheridia near the base. Perithecium 125 X 32 p, the tooth-like appendage 20 ft. Receptacle

A more careful 1 examination of the type of this species suggests that the very peculiar conformation 
ot the tip o the pentheemm may be to some extent abnormal.. It is to be hoped that more material may 
be obtained Iron, winch its characters may be more exactly determined. It is hardly possible to say to 
what species it is most nearly allied.
