New Species of Fungi 
167 
Sporidia biseriate or oblike, oblong-fusoid, hyaline or with a 
yellowish tint, uniseptate in the middle and slightly constricted, 
14-18 x 4-6^. 
Metasphaeria silphii E. & E. On dead stems of Silphium 
integrifolium, Rooks Co., Kansas, May 1902. (Bartholomew 
2951)- 
Perithecia gregarious, subcuticular becoming superficial 
when the cuticle falls away, ovate, rough except the upper part 
and the papilliform ostiolum, soon collapsing to cup-shaped, 150- 
200 p diam. Asci cylindrical or clavate-cylindrical, 45-55 x 6-7 p } 
rather abruptly contracted into a short, stipe-like base,!paraphysate. 
Sporidia biseriate or oblike, fusoid-oblong, 2-3-septate, con¬ 
stricted at the septa, 12-16 x 3J-4A, slightly brownish. In some 
perithecia the sporidia are 2-septate and in others all 3-septate. 
Cryptovalsa pirina E. & E. On dead limbs of Pirus coro- 
naria, River Forest, Ill. Oct. 1902. (E. T. & S. A. Harper, 600.) 
Com. E. Bartholomew. 
Stroma effused, blackening the inner bark and the surface 
of the wood beneath. Perithecia ovate-globose, with thick, cori¬ 
aceous walls, the inner cavity mostly less than ^ mm. diam., col¬ 
lected in valsoid groups (generally 4-8), with short necks, their 
entire or faintly sulcate, obtuse or subconical ostiola erumpent 
in an acutely elliptical or round disk which bursts out through 
short, transverse cracks in the thick epidermis. Asci polysporous, 
on long, slender pedicels, p. sp. 65-70 x 10-12 p. Sporidia allan¬ 
toid, yellowish, not strongly curved, 11-13X \\- 2 p. 
This differs from C. protracta (Pers.), C. nitschkei Fckl., 
and C. rabenhorstii (Nitsch.) in its ostiola being collected in an 
erumpent disk. 
Valsella minima Niessl. Not. Kr. Pyr. p. 53. What we 
take to be this species has been sent by Prof. E. T. Harper, from 
Indiana, on Sambucus canadensis. 
Stroma -J-J mm. diam., sunk in the inner bark which is 
uniformly blackened on the surface. Perithecia 3-6 in a stroma, 
angular from mutual pressure, white inside, minute, about 200 p 
in diameter. Sporidia 8-ioxiJ-2£t. Ostiola scarcely penetrat¬ 
ing the minute, white, farinaceous disk. 
Anthostomella thyridioides E. & E. On decorticated, 
weather-beaten limbs of Populus deltoides, Rooks Co., Kansas. 
July 1902. (Bartholomew 2969). 
Perithecia gregarious, one or two together, globose, thin 
walled, sunk in the wood without any definite stroma and raising 
the surface of the wood into short, subelongated pustules pierced 
by the papilliform ostiola and blackened by the discharged spo¬ 
ridia. Asci clavate-cylindrical, 70-75 x 10-12^, paraphysate. 
Sporidia oblong-cylindrical, continuous, brown, 15-22 x 4-6 p 
Has the aspect of Thyridium.
