PLEURAGE 91 
free with age, 375-525 2 x 550-7504, thin, membranaceous, 
greenish below, often somewhat transparent, pyriform with papilli- 
form to somewhat elongated cylindrical black bare usually curved 
beak, the whole lower portion of the perithecium and often the 
surface of the substratum covered with a considerable growth of 
mycelium in the form of rhizoids. 
Asci 64-spored, clavate to fusiform, contracted and narrowly 
rounded above and contracted below into a short narrow stipitate 
base, evanescent, 60-110 4 x 250-300 4: paraphyses ventricose 
below, tubular septate above, longer than the asci. 
Spores in several series, ellipsoid, rounded at both ends but 
usually more broadly so below, 18-22 # x 32-37 p, ranging from 
hyaline when young through olivaceous to dark brown and 
opaque; primary appendage cylindrical, equal to or longer than 
the spore; the base of this is surrounded with 2 to 4 hyaline 
gelatinous secondary appendages of various form and size, the 
apex of the spore being crowned by a tuft of very fine filaments 
closely united into a short blunt straight or curved appendage. 
Pl. ro. f. 7-10. 
Distinctive characters : The spore appendages. 
Cultivated specimens : On cow and horse dung, New York 
City and Ft. Lee, N. J., summer 1899; cow dung, Biloxi, Miss., 
Sept. 1899 (Tracy); cow dung, Auburn, Ala, Aug. 1899 
(Earle). 
Both the perithecia and the spores of this species resemble 
those of P. decipiens very closely. The upper appendage of the 
spores, however, is narrower and longer and contains fewer fila- 
ments in its composition. 
The measurements given are those of the New York specimens 
which were very thoroughly studied when the species was first 
found. The Alabama specimens show considerable variation in 
spore measurements, some being as low as 16 م‎ x 27 رم‎ these it 
appears to me had best be treated as simply a variation in the 
species because no other differences were observable. 
31. Pleurage adelura sp. nov. 
Perithecia sunken, scattered; about 450 x 750 رم‎ thin, mem- 
branaceous, brown and opaque, pyriform, with a smooth, black 
papilliform to cylindrical projecting beak. 
Asci 64-spored, fusiform-clavate, contracted and narrowly 
rounded above and tapering below into a stout stipe, about 75 م‎
