MEMORABILIA. 
Sphjiria caryophaga, Schwein. Amer. Bor. No. 1594, Sacc. 
No. 4332 ; Sphoeria nuclearia, De Not. Micr. Ital., ix., p. 462, f. 
iv. ; Trematosphceria nuclearia, Sacc. Syll. No. 3308 ; Sphoeria 
( Pertusce ) Curtisii, Berk, in Curt. Catalogue, p. 145 (from 
authentic specimen from Dr. Cnrtis) ; Hypoxylon nucitena , 
B. & C., North Amer. Fungi No. 844; Melanomma? nucitena, 
Sacc. Syll. No. 3239. From authentic specimens of Schweinitz, 
Berkeley, and Curtis, and the figure and description by Notaris, 
we are satisfied that the above are all one species. Sporidia 
triseptate, two middle cells dark -brown, extreme cells hyaline, 
015-018 x 005 mm. The colour is often so deep as to mask the 
central septum, which has caused some discrepancies in the 
descriptions. 
Chromosporium isabellinum, Ellis d’ Sacc., N. A. Fungi No. 
1391, is the same as Chromosporium pactolinum, Cke. 4' Hark., 
“ Grevillea,” ix., 81.
