2. Pleurage anserina (Os.) Kuntze, Rev. Gen. Plant. 3 ': 504. 1898. 
Sphaeria anserina Ces.*, Rab. Hedwigia 1: 116, as synonym. 1857. 
Malinvernia anserina Rab. Hedwigia 1: 116. 1857. 
Mycelium superficial, hyaline to brown, branched, septate; perithecia 
scattered uniformly or aggregate, usually half-sunken but often entirely 
superficial, pyriform, with beak papilliform or slightly cylindric and usually 
curved, 500-730x190-380 mic., black above with a tinge of green below 
due to young spores, opaque, thin, membranous, smooth except portions of 
the beak which bear tufts of hairs which are simple, straight, 140-290x3-4 
mic., sparingly septate, smooth, light-brown to pale towards the tip, 
persistent; paraphyses simple, filiform or slightly ventricose below, 
decreasing in diameter upward, numerous, 1.5-2 times the length of the 
asci, septate, indistinct at time spores are mature; asci cylindric, slightly 
contracted and rounded above, and contracted below into a long, slender, 
often crooked stipe, 175-305x22-30 mic., 4-spored, opening by a cap-like 
lid, quite persistent; spores generally obliquely 1-seriate, ranging from 
hyaline when young through olivaceous to dark-brown and opaque, ellipsoid, 
27.5-40x15-17.5 mic., terminated below by a short hyaline primary 
appendage 1-1.5 times the length of the spore, this as well as the apex of 
the spore terminated by a long lash-like, gelatinous appendage of variable 
length, which by proper illumination can be resolved into 2 closely united 
strands which gradually merge into one another distally, primary append¬ 
age persisting longer than secondary appendages, often found on mature 
spores. 
Habitat: On dung of horses, cows, sheep, rabbits, and dogs; also 
on old pasteboard and Chinese mats. 
Distribution: Vermont to Ohio, South Dakota, and New Mexico; also 
in Europe.

Club 11: pi. 5, f. 4-6. 
Type Locality: Europe. 
Distinctive Characters: Dorsal tufts of long hairs and 4-spored 
asci. 
Notes: Griffiths and Seaver give perithecia 400-500x300-350 mic., asci 200-400x17-22 mic. 
and spores 34-42x18-20 mic 
Plants cultivated in the laboratory, Feb. 10, 1917, on rabbit dung collected by Wm. Schaeffer, 
near Wyoming, Oct 3, 1914; also June 13, 1917. on cow dung collected by the author, near Georgetown, 
Sept. 7, 1914; on potato hard agar from March 21. to April 2, 1917, maturing in 12 days or less.
