274. Ceuthospora Mahonise, sp. n. 



Stromatibus epiphyllis, gregariis, dimorphis : (1) pro ratione 

 magnis, durissimis, convexis, prominentibns, solidis, rotundatis v. 

 oblongis, ^-1 mm. diam., e folii cortice efformatis, intus brunneis, 

 extus nigrescentibus, epidermide lacerata velatis, dein cinctis, loculos 

 20-40 minimos confertos rotundos albo-farctos forentibus, (2) minori- 

 bus 250 /* 1-7-locellatis, truncato-conicis, denique in discum parvum 

 rotundum albido-furt'uraceum poro centrali perforatum erumpentibus. 

 Sporulis rectissimis, cylindricis, apice obtusis, continuis, hyalinis 

 eguttulatisque, 10-14 X 1^-2 jjl. 



Hab. in foliis emortuis Malionice jnponicfe, Studley ( Wk.), Junis. 



The state of things in this species on Malionia is very similar to 

 that of the species on Euonymus described in Journ. Bot. 1916, 

 p. 190 ; there are two kinds of stromata, differing in appearance, 

 (a) subunilocular or at least paucilocular, {b) multilocular, the latter 

 being later in development than the former, though the spores are 

 exactly identical in both. But the larger stromata of C. Mahonice are 

 quite different in shape from those of C. Euo7iymi, and resemble more 

 those of G. Alaterni Thiim.

Conceptacles amphigenous, roundish, immersed, then convex and 

 erumpent, splitting the epidermis into four or five lacinise, black, 

 about \ mm. diam. ; loculi one or several, immersed in a brownish 

 stroma and often imperfectly divided. Spores cylindrical, straight, 

 obtuse at both ends or somewhat tapering below, 8-10x1|-2/a
