Externally this resembles Diatrype cornuta E. & E., but the 

 stroma is differently tinted, and the asci and spores are larger. 



Diatrype albopruinosa (Schw.) C. &. E. 



On dead branches of Acer neomexicanum Greene (14683 p.p.) 

 and on old scrub oak branches {Quercus Fendleri Liebm. ?) 

 (13660 and 14693 p.p.). 



Diatrypella Placenta Rehm. 



On dead branches of Alnus tenitifolia Nutt. (14771). Agrees 

 with specimens in Rehm's Ascomyceten, No. 1984 and Tranzschel 

 and Serebrianikow, Mycotheca Rossica, No. 225. 



Hyalosporae 



Physalospora Galii Rostr. 



Perithecia gregarious, single or 2-4 in a cluster, lenticular or 

 globose-depressed, membranaceous and of loose cellular struc- 

 ture, surrounded at base by brown mycelial hyphae, often seated 

 on yellow or brown discolored areas, immersed, then erumpent, 

 opening by a central pore, black or brown, 100-200 /x in diam. ; 

 asci oblong, broad, rounded at both apex and base, 8-spored, 40- 

 44 X 10-13.33 /x ; spores obliquely biseriate or crowded, fusoid- 

 oblong or cymbiform, mostly rounded at the ends, one end apt 

 to be a little broader, simple, continuous, minutely granular or 

 nucleolate, hyaline, 13-17 X 3-33 - 6/x> paraphyses few, filiform. 



On old stems of Galium borcale L. (14757 P-P-)- 

 The broad asci differ from Rostrup's original description 

 (Bidr. Ascom. Dovr. in Kristiana Videnskabs-Selskabs Forhandl. 

 9: 7. 1891. Accompanied by a Phoma and Rhabdospora too 

 scanty for determination, and Microdiplodia galiicola sp. nov.
