(aR. J. B. ELLIS. ) 
Perisporium Wrieutiu B. & C. 
On Opuntia Tuna (L.) Mill. Inagua. 
PHYLLACHORA OXxALINA. E. &E. N. A. P. 602 
On Oxalis corniculata L. Nassau. 
PARODIELLA GRAMMODES (Kze.) Cke. 
On Crotalaria retusa L. Lucea. 
Crrcospora Metocurak Carleton in litt. 
On Melochia tomentosa L. Eleuthera. 
MELIoLa smuituima E. & E. n. sp. 
On Hehites Browneti J. Miill. Nassau. Dec. 1890. 
Mycelium branched, radiating, forming patches 2-4 mm. diam. or 
larger by confluence. Threads about 5 / diam. with alternate hyphopo- 
dia. Capitate hyphopodia narrowed below, ovate, faintly uniseptate, 
15 8-10. Mucronate hyphopodia flask-shaped, about 15 6-7 4, 
paler brown. Bristles arising from the mycelium, simple, straight or a 
little curved, 150-200 5-6 1, septate, soon opake. Perithecia globose, 
rough, 100-115 # diam. Asci ovate, 80 20 #, 2-spored; paraphyses 
none, Sporidia cylindrical, obtuse and rounded at the ends, 4-septate 
and slightly constricted at the septa, 24-28 10-12 pw, 
This comes near M. microspora Pat. and Guill., but that has stouter 
bristles, coarser subcrustose mycelium and smaller sporidia, and is 
found on a different order of plants. 
SPHAERELLA Raganiar E. & E. n. sp. 
On leaves of Rajania hastata LL. Nassau. Nov. 1890. 
Perithecia hypophyllous, gregarious in small groups, not on very 
decided spots, about + mm. diam., subcuticular, black, subcollapsing, 
the minute, papilliform ostiolum barely piercing the blackened epidermis. 
Asci oblong-cylindrical, sessile, 60-65 X 8-10 /, obscurely paraphysate, 
8-spored. Sporidia biseriate, oblong-fusoid, hyaline, faintly uniseptate, 
18-20 & 4-5 #. 
Puy.uosticta Cocconopan E. & E. on. sp. 
On leaves of Coccoloba uvifera (L.) Jacq. Nassau.

Spots amphigenous, orbicular, 3-5 mm. diam., purplish-red, with a 
slightly raised, darker colored border, outside of which is a narrow, 
paler, shaded margin, bordered with an appressed, coarse, light colored 
fringe. Perithecia innate, mostly hypophyllous, minute, invisible with-
