*' Light yellomsh brown; pseudoparaphyses in small numbers, bent, about as Iqng as the 
pcrithecium and colorless." 
On the legs of Anchomenus viduus Pz., vicinity of Yienna, Austria. 
As in the previous instance^ this species cannot be determined from published data. It seems 
peculiar from the elongation of cell IIIj but is otherwise without characters which would 
distinguish it It may have to be ultimately united with one or both of the preceding species.

Becoming more or less deeply suffused with olive brown. Pcrithecium often irregularly 
bent, its lip cells prominently distinguished, distally nearly truncate. Appendages arising side 
by side in a plane at rigiit angles to the usual position, so that there appears to be but one 
appendage, the larger (outer) usually once branched above its sub-basal cell, the smaller (inner) 
cunsisting of a small basal cell bearing usually two short branches more commonly .simple, and 
bearing small groups of antheridia. Receptacle rather small ; hyaline, becoming more or less 
deeply suffused with brown, except the lower part of the rather large basal cell ; cell V twisted 
out of its normal position and only visible on one side, as a rule. Spores, 45 X 4.5 fi. Tcri- 
thecia, 100-120x40^. Appendages, longest, 250-350 /.. Total length to tip of pcrithecium, 
160-222 u.

This small species appears to be constant in its characters, and is at once separable by the 
(IV) 
of the receptacle, and which would lead one to suppose, at first sight, that the plant had but one 
appendage, as was stated in the original description. It usually occurs on the thorax of its hosts 
and on the adjacent bases of the elytra.

More or less deeply tinged with olive brown. Perithecium becoming almost or quite opaque, 
somewhat mfla ted, a slight depression at its base above the more or less bulgi„g tern.inal portion 
the reeep .ncle, .ts apex stout, snout-lilce, bent slightly inward. Appendages arising from t.o 
basal cells the outer of which gives rise to a single simple or rarely once branched rigid branch, 
branches almost mvanably simple, and bearing near the base solitary sessile antheridia. Recep-
