New Species of Fungi 
IT 
Physalospora minima E. & E.— On dead canes of Rubus 
strigosus. Tuskegee, Ala. (Prof. G. W. Carver). 
Perithecia evenly scattered, subcuticular, the minute ostiolum 
barely rupturing the epidermis, small (80-90 11). Asci oblong- 
clavate, short-stipitate, paraphysate, 40-50 x 6 m . Sporidia irreg¬ 
ularly crowded in the asci, elliptical, mostly narrowed at the ends, 
9-11 x 3-4 ju. 
Smaller in all parts than P. vagans E. & E. var. rubi on the 
same host. 
Pleospora kanensis E. & E.— On dead stems of Meli- 
lotus alba. Rooks Co., Kansas, June, 1901. (Bartholomew, 
2888). 
Perithecia scattered, subcutaneous, ovate-globose J--J- mm. 
diam., raising the closely appressed cuticle into pustules pierced 
at the apex by the conical or short-cylindrical ostiolum, finally 
collapsing to cup-shaped. Asci clavate, rounded above, gradu¬ 
ally narrowed below to the short, nodular stipe-like base; para- 
physes stout (3 u thick), septate, hyaline; sporidia biseriate, ob- 
long-obovate, rounded above, narrowed below and bent a little 
to one side, 5-6-septate, with a longitudinal septum more or less 
distinct running through 2 or 3 of the middle cells, slightly con¬ 
stricted in the middle, bright straw-yellow, 20-22 x 7-9 n . 
This comes very near P. meliloti Rabh. on the same host, 
but the shorter clavate asci, the smaller sporidia and short-cylin¬ 
drical ostiolum may perhaps separate it. P. dura Niessl has 
larger perithecia which do not collapse. 
Leptosph^eria astericola E. & E.— On dead stems of 
Aster multiflora. Rooks County, Kansas, June, 1901. (Bar¬ 
tholomew, 2885). 
Perithecia erumpent-superficial, globose, becoming depressed 
or collapsing to cup-shaped, subseriately arranged, sometimes 
2- 3 confluent, ostiolum papilliform, more distinct in the col¬ 
lapsed perithecia. Asci subcylindrical, short-stipitate, paraphy¬ 
sate, 80-110x7-8 n ; sporidia biseriate, fusoid, slightly curved, 
3- septate, not constricted, straw-colored, 30-40 x 3-4 n . Pycni- 
dial perithecia resembling the ascigerous but not collapsing, 
sporules oblong or oblong-elliptical, hyaline, 6-8 x 2.\- 3 m , uni- 
septate. 
Allied to L. fusipora Niessl and L. leptospora DeNot., but 
both have much shorter, broader sporidia and the latter has the 
pycnidial spores continuous. 
Metasph^ria subseriata E. & E.— On dead culms of Pan- 
icum virgatum, Rooks County, Kansas, March, 1901. (E. Bar¬ 
tholomew, 2841). 
Perithecia buried in the unchanged substance of the culm, 
raising the epidermis into distinct pustules pierced by the papilli¬ 
form ostiolum, depressed-globose, J-J mm. diam., scattered
