Diaporthe tessera Fr. is mixed with it in the type material. In 

 several particulars this agrees with the European D. Tocciaeana 

 de Not., a species which Dr. Peck reported on hazel at Sandlake, 

 N. Y. ; but the latter is said to exhibit a dark circumscribing line 

 and to have brownish sporidia, 5-7 X 1-5/*. 



3. Botryosphaeria Sumachi Cooke, Grevillea 15: 80. 1887

Mr. S. H. Burnham's 125 on Rhus glabra, Warren Co., N. Y., 

 is ascigerous — a Botryosphaeria whose stromata externally and in 

 cross section are exactly like Prof. Peck's W. Albany collection 

 on the same host labeled Sphaeropsis Sumachi (Schw.) Cooke & 

 Ellis. The latter is really a Haplosporella consisting as it does 

 of flat, black stromata containing 2-8 internally white pycnidia, 

 75-90 fx. The former shows both the brown conidia of the latter 

 and thick-walled asci containing eight hyaline, fusoid sporidia 

 18-20 X 6-8 ft. It may be another of the numerous forms of 

 Botryosphaeria fuliginosa (M. & N.) but the perithecia are not 

 botryoidally aggregated and the asci and sporidia are smaller. 

 Cfr. Haplosporella Burnhami sp. nov. on a subsequent page. 



My copy of Fungi Columb. 105J labelled Sphaeropsis Sumachi 

 (Schw.) is not a Haplosporella. The spores are larger and 

 usually contain a single large nucleus instead of the usual two 

 nuclei of Haplosporella Sumachi. 



4. Sphaerella trichophila Karst. f. Saxifragae 



This Sphaerella has characters connecting it with S. minor 

 Karst. and with S. pachyasca Rostr. both of which inhabit Saxi-
