330 MOXOGRAPH OF THE LABOULBEXIACE^. 
This small species is allied to L. parvula in general form, but is at once separable by its 
stouter carved appendages. It occurs only on the legs of the host mentioned, usually in small 
nnmbcrs, and is very constant in its characters.

Olivaceous. Perithecinm straight, rather small, symmetrically inflated, the sliort, almost 
truncate, black apex abruptly distinguished ; the wall-cells distinctly spiral. Outer appendage 
consisting of a basal cell bearing distally a terminal and on the inner side a sub-terminal branch ; 
each usually once branched above its basal cell: the inner appendage consisting of a much 
smaller basal cell, producing two branches, each of which may be once branched, the ultimate 
branchlets of both appendages stiff, erect or diverging slightly towards the pcrithccium, taper- 
ing slightly, rather closely septate and about equal. Receptacle long, straight and rather 
slender. Spores, 75-80 x 6-7 /x. Appendages, longest, 200-250 ^l. Terithccia, 150-180 x 50- 
75 ii. Total length to tip of perithecium, 350-430 /u. 
On Platynus extensicoIUs Say, Maine and Connecticut, 
This rare species was found in several localities about New Haven and at York, Maine, 
attached to the anterior legs of its host in company with L. scelophila, winch is, perhaps, its 
nearest ally ; although readily distinguished by its smaller size, different shape and curved 
appendages.
