FAIRMAN — PYRENOMYCETE^ OF ORLEANS COUNTY. l8l 



There are small oblong conidia and larger, 40 x 6 //, multiseptate 

 fusiform spores found on the basal threads. The paraphyses are 

 indistinct. On the surface of wood (bassvvood?) under moist bark. 

 Lyndonville, N. Y. , Oct., 1900. LasiosphcEria sulphurella Sacc. is 

 seated on a sulphur-colored subiculum and the appendages of the 

 sporidia are 25-30 p. long, LasiosphcBria viridicoma (C. & P.) is 

 clothed with a dense greenish tomentum and Lasiosphcpria midabilis 

 has a yellowish-green tomentum which turns brown and disappears. 

 The iiavo-virescent color of the crushed perithecia and the occasional 

 appendages of the sporidia render our species difierent from the type 

 of L. ovina (Pers.). At first we considered it a new species {Lasio- 

 sphceria aiireliana Fairman, in herb. ) but Mr. J. B. Ellis, the veteran 

 American pyrenomycetologist, to whom specimens were submitted, 

 thought that the color of the crushed perithecia did not entitle it to 

 specific rank. It is to be noted, however, that in Eutypa flavo- 

 virescens (Hofi. ) Tul. and Lccanidion indigoticuni (C. & P.) Sacc. 

 the interior color of the fungus is a diagnostic feature.

 station for this in the United States, so far as reported. According to 

 Ellis and Everhart, "asci and sporidia in the New York specimens are 

 smaller than the measurements given by Dr. Winter (170-220 x 

 35-42 // and 45-65 X 17-21 /A)."
