18 x 12 y, borne at the ends of delicate hyaline hyphae, about 
12x 3y. What connection, if any, these have with the

Micropeltis longispora sp. nov. 
Epiphyllous; perithecia scattered, easily separating, dark 
brown, slightly roughened, 300-400», hemispheric-appla- 
nate, umbilicate, the ostiolum slightly sunken, of prosen- 
chymatous tissue composed of fine interwoven threads, which 
extend beyond the fertile portion, forming a flat, sterile sub- 
iculum 100-200 # wide; asci elliptical, aparaphysate, 70- 
80 x 25-304; spores cylindrical, often curved, hyaline, 
multiseptate, granular, ends obtuse, 50-70 x 8 yu. 
On living leaves of Coffea Arabica, Porto Rico, Heller, 
no. 6349. 
The leaves are also overrun by the sterile mycelium of 
some Aprosporium. 
This differs from Micropelt’s Tonduztd Speg. in the 
larger, much more frequently septate spores which have the 
cells all equal, not one or two of them enlarged as in that 
species.

ostiolum short, smooth, umbilicate; asci broadly ns 
crowded with spores, short-stipitate, 70-80 x 10-12 /£; asco-
