DELITSCHIA 105 
[ 200 4: paraphyses filiform, abundant, indistinctly septate, much 
longer than the asci, and mixed with them. 
‘Spo res biseriate, ellipsoid, sharply rounded at the ends, two- 
; celled, not constricted at the septum, 16-21 » x 28-344; hyaline 
envelope entirely absent, but the spore is tipped at each end with 
a short hyaline triangular apiculum. )۶۸ 73. f. 70-13.) 
Distinctive characters : Hyaline apicula of the spores. 
Cultivated specimen: On dead stems of Russian thistle, 
Aberdeen, S. D., March 1898. 
The species is not to be considered even semiparasitic. The 
stems of Salsola Kali tragus were collected in a rubbish heap 
where they were found infected with some other pyrenomycetous 
I fungus. These were placed in a moist chamber in March 1899 
and kept in a moist condition until the first of June. Some time 
in the latter part of May, the mature perithecia of this fungus 
were found in considerable numbers 
The septa of the spores do not appear as early as in the 
majority of the species of the genus. The illustration of the ascus 
| 3 was made when the spores were in the yellow condition, yet they 
| showed no signs of the septa which are visible in other species 
before the spores have left the hyaline state. 
9. Delitschia polyspora sp. nov. 
Perithecia scattered, sunken, with a projecting truncate black 
bare shining cylindrical straight or curved beak of variable length, 
about .65—75 mm. x I mm., subglobose to pyriform, slightly 
coriaceous, dark brown to black and opaque. 
Asci 16-spored, clavate to fusiform, broadly rounded above 
and rather abruptly contacted below into a short blunt stipe, 
85-100 4 x 340-375 ہم‎ rather persistent : paraphyses filiform, 
septate, abundant, longer than the asci, and mixed with them 
pores triseriate to crowded, ellipsoid, usually broadly rounded 
at the ends, uniseptate with a broad deep constriction, 21-24 م‎ 
x 52-62, ranging from hyaline when young through yellow to 
dark brown and opaque; hyaline envelope prominent and having 
an evident septum which may be distinctly seen when extended in 
water er to that of the spore. CL rg. Jr 
Distinctive characters: Large size throughout amd many- 
spored ascus. 
Cultivated specimen : On cow dung, Tucson, Ariz., Jan. 1900 
( Tyler).
