HYPOCOPRA 99 
measurements given are inaccurate. Specimens distributed by 
Plowright and named by Dr. Winter are at hand in which the 
spores measure exactly as quoted above. 
The development was very profuse in both the South Dakota 
and the Kansas specimens—four of the samples sent me by Mr. 
Bartholomew having more or less of this fungus on them. 
8. Hypocopra parvula sp. nov. 
Perithecia sunken and aggregated into small clusters with small 
black smooth papilliform beaks extending through a black smooth 
crust like stroma which is definitely bounded, 300-450 y in diam- 
eter, thin membranaceous, white below the stroma, and densely 
covered with fine flexuous hairs which bind the perithecia of the 
group firmly to each other and to the substratum. 
Asci 8-spored, cylindrical, rounded above and contracted be- 
low into a long crooked stipe, 9-12 x 95-105 ,م‎ rather per- 
sistent; apical structure coloring blue with iodine: paraphyses 
filiform, not numerous, guttulate, sparingly and indistinctly septate, 
slightly longer than the asci and mixed with them. 
Spores obliquely uniseriate, ellipsoid, rounded at both ends but 
often more acutely so below, 10-13 م‎ x 6-7 u; gelatinous cover- 
ing swelling moderately in water ; germinal slit lateral and extend- 
ing nearly the entire length of the spore. (PZ 19. f. 7-9.) 
Distinctive character: Small size throughout but more espe- 
cially of the spores. 
Cultivated Specimens: On cow dung, Summit, Mont., Aug, 
1900 (Griffiths & Lange). 
9. Hypocopra rostrata sp. nov. 
Perithecia sunken, aggregated in small clusters in a dense felt- 
work of white to light brown mycelium which scarcely assumes 
the character of a true stroma, subglobose to oval, 300-400 م‎ 
in diameter, colorless below and densely covered with a fine white 
mycelium which becomes but slightly condensed toward the sur- 
face; beak black, shining, prominent, hood-like and projecting 
through the pseudostroma. 
Asci 8-spored, cylindrical, rounded above and contracted below 
into a short stipitate base, 21 / x 213—286 بر‎ : apical structure prom- 
inent and coloring bright blue with iodine: paraphyses filiform, 
septate, longer than the asci and mixed with them. 
Spores obliquely monoseriate, ellipsoid, rounded at both ends, 
13-18 p x 29-32 ,م‎ ranging from hyaline when young through 
yellow to dark brown and opaque ; germimal slit lateral, promi-
