This pale form was found in numbers and in good condition on the large Staphyiinid above mei 
tioned. Though it possesses no very marked individuality, it is easily distinguished by Its relatively short 
and broad receptacle, cells III and VI of which are almost equal, though .,11 III may Ik- slightly the 
longer of the two. The perithecium, which is usually straight and relatively long, is often t on the 
receptacle a little within the external margin and, as in L. Anaphgcnii, the ins. rtion-cdl h: a charac- 
teristic red-brown or claret-colored tint.

transverse striations which are less distinct on the cells above it. 
Appendages concolorous, the outer simple (always?), the inner consisting of a basal cell similar to thai 
of the outer, about twice as long as broad, giving rise on either side to a single bra .
