moutliy which is usually, but not always, bent abruptly outward almost at right angles to the 
nearly straight inner marghi of the perithccium. A short, straight, bluntly -pointed, rather 
stout appendage arises on one side only of the pcrithecium, just holow this tubular apex bej^ond 
which it projects. The basal and sub-basal cells of the receptacle about equal in length, the lat- 
ter broader: distal portion of the receptacle composed of the usual four cells, the sub-termi- 
nal cell forming a distinct external prominence below the terminal cell, which is bent toward and 
partly overlaps the pcrithecium. Perithccium (main body), 60 x 1'8/x, its tubidar apex, 18-25 X 
6/1. Spores, 20 x 3/i. Length of receptacle, 110 /jl. 
On Zaecophtlus maeiilosiis Germ., Connecticut. 
A singular species appearing at first sight malformed or abnormal. It occurs in company 
with C. appendiculatus on the anterior legs of its host, and is at once recognized by the tubular 
prolongation of the apex of its perithccium.

Erownisli yellow. Perithecium small, its tip slightly exceeding that of the receptacle ; its 
extremity blunt, lobcd, curved outward, and bearing two projections unequal in size just below 
the tip, one of which extends outward beyond the perithecial margin as a blunt prominence. 
Basal cell of the receptacle often bent, expanding distally, much longer than the flattened sub- 
basal cell : the distal portion of the receptacle with greatly thickened external walls, and 
consisting of the usual four cells, the terminal one short, with a broad bas^ and bent towards the 
apex of the penthecium. Thrcesmall cells are distinct below the perithecial cavity, from the 
outer of which is produced externally a prominent spur-like process. Perithccia,' 55 X 15 /..
