5. Pleurage tetraspora ( Wint.) 
Sordaria tetraspora Wint. Hedwigia, و‎ : 161. 1871 ; Zeitschrift 
gesammt. Naturwissen. // 6.f. r. 1883; Griffiths, Bull. Torr. 
Club, 26: 435. M. T. f. 70-72. 1899. 
Perithecia superficial, pyriform to conical, scattered, thin, mem- 
branaceous, colorless to fuscous and so transparent that the spore- 
bearing area which occupies rather less than halfthe length of 
the perithecium can be readily distinguished by transmitted light, 
covered with short septate agglutinated hairs which are more 
prominent around the smooth black naked erect or curved beak, 
140-180 # x 360-510 1 
Asci 4-spored, cylindrical, rounded above and contracted below 
into a stipe one-half the length of the spore-bearing portion, 15— 
18“ xX 100-110 4: ive gë ventricose, longer than the asci, 
but not much mixed with t 
ores uniseriate, deeg broadly but acutely rounded, 
fugacious ; both primary appendage and apex of spore tipped 
with long lash-like, gelatinous secondary appendages which are 
made up of two or more filaments closely united. 
Distinctive characters: Agglutinated hairs, 4-spored asci, and 
small size. 
Cultivated specimens: On dead culms of Poa Nevadensis, 
Big Horn Mountains, near Buffalo, Wyo., Aug. 1898 ( Williams 
& Griffiths); horse dung, Summit Mont., Aug. 1900 ( Griffiths 
& Lange). 
This species was established by Dr. Winter * upon a single 
perithecium collected in Saxony in 1871. Two years later, in 
1873, when he published his monograph } of the German species, 
he remarked that he was hasty in his judgment in his former 
paper and reduced the above name to a synonym, at the same 
time remarking that as the 4-spored characteristic appears con- 
stant it might be well to retain the name, ¢e/raspora, for the va- 
riety. Later he found many specimens of the 4-spored form in 
his own collections; but from Dr. Lange and Herr Fuckel he 
received specimens which contained the 8-spored form as well. 
The specimen from Fuckel was accompanied by a diagnosis and
