Boseliinia caespitosa E. & E. 



Ou (lead limbs of Celtis occldentalk, Rockport, Ks., Nov., 1893 

 (Bartholomew, No. 1,252). 



Perithecia densely gregarious or cespitose, minute (175-200/x 

 diara.) ovate-globose, rough, with conical or couic-papilliform ostio- 

 luiu. Asci cylindrical, 60-79 x 8// when the sporidia lie obliquely,. 

 75-90,". long when they lie end to end, paraphysate, 8-spored. 

 Sporidia uuiseriate, rather acutely elliptical, brown, continuous, 9- 

 13x6-7//. 



Distinguished by its small, rough, clustered perithecia. 



Rosellinia bicolor E. & E. 



Ou rotten wood, Louisiana (Langlois). 



Perithecia gregarious, hemispherical, black-brown, 2 mm. diam. , 

 thin and fragile, seated on a white subiculum of interwoven, branch- 

 ing hyphae. Asci cylindrical, 125-140 x 8//, 8-spored, paraphy- 

 sate. Sporidia uuiseriate, broad- fusoid, subinequilaterai, 3-4 

 nucleate, hyaline becoming brown, 20-23 x 6-7//. 



Perithecia only about half as large as in R. morthien Fckl. , and 

 not flattened at the apex. Ostiolum minute, papilliform. 



Eosellinia ostiolata E. & E. * 



On bark of Ulmus Americana, Rockport, Kansas, Apr.. 1894

 at the base, with a stout, obtuse, short- cylindrical, or conic-cylindri- 

 cal ostiolum. Asci clavate-cylindrical, 150x25//, paraphysate, 

 8-spored. Sporidia rhomboid- elliptical, longitudinally rugose, 

 brown, continuous, 25-38x20-22//. Some of them smaller and 

 suliglobose, but this may be a deformity. 



Rosellinia pinicola E. & E.

 times slightly compressed. Asci cylindrical, 60-65x45//, p. sp. 

 40-45//. long, paraphysate, 8-spored. Sporidia uuiseriate, elliptical, 

 5-8 X 3-4//, the shorter ones sub-globose, brown, 2-3-nucleate.
