FAIRIMAN — PYRENOMYCETE.E OF ORLEANS COUNTY. 185 



N. A. Pyr., it is stated that the specimens from Lyndonville differ 

 from the diagnosis in Sylloge " in having the asci and sporidia smaller: 

 asci 75-90 X 12-15 /^ : sporidia 25-35 i^ 6-7 //, 6-7 septate, only slightly 

 constricted and obscurely appendiculate."

329. Lophiostoma triseptatum Peck. Peck, 28 Rep. p. 

 76. N. A Pyr., p. 224. A common species and somewhat variable. 

 Ellis and Everhart in N. A, Pyren. say ' ' differs from L. quadrimic- 

 leatuin Karst. in its smaller sporidia, constricted at the apex". L. 

 triseptahmi Peck, should probably be referred to L. quadrimtcleatuTn 

 Karst, as a small spored variety. In the diagnoses of Lophiostomas 

 published in the Sylloge, there are a number of small spored forms, in 

 length from 15 to 25 /^, which are difificult to separate. The forms we 

 enumerate here as L. triseptatum occur on various habitats. Two of 

 them have been examined by Prof. Peck and pronounced to be his 

 species, viz. : On fallen branches of Fraximts, with the bark still on 

 and the perithecia erumpent, July 25, 1890. On decorticated, fallen, 

 branches of Acer, Oct. 8, 1891. Normally this fungus has triseptate 

 sporidia, but occasionally one or both of the terminal cells are divided 

 by a septum and we have forms 4-5 septate, enumerated as Lophios- 

 toma rhopaloides Sacc, V2.x. pluriseptata, n. var., in Fairman, Fungi 

 of Western, N. Y., Proc. Roch. Acad. Sc, Vol. i, page 49 and in 

 Farlow and Seymour's Provisional Host Index of the Fungi of the 

 United States, Part III., page 192, (sub Acer, sp. indeter. ) These 

 should be cancelled and the form known as Lophiostoma triseptatum
