veloped hyaline stroma are the perithecial cavities. In teasing 
“ specimen the asci and paraphyses adhere together and often 
fall out entire, like the meat from the shell of a nut, leaving a 
mold of their form behind. 
Meliola Fries. 
Mehola melastomacearum Speg. On Miconia impetiolarts, 
Mayaguez, 3922; on Heterotrichum cymosum, Utuado, 4359, 
Meliola sp. indet. On Podocarpus coriaceous, Maricao, 
6774. 
The mycelium here is unquestionably that of Meliola, but 
no perithecia are present. The specimen is worthy of note 
since no Meliola is recorded on this host or its family.

Hyalosphaera, gen. nov. type H, micomae. 
Hyalosphaera micontae, sp. nov. 
Spot indefinite, roughly circular, above pale to yellow, 3-10 
mm. in diameter; below pale and coated with buff mycelium 
centers ashen-grey due to ascospore color, mycelium 5 », sep- 
tate, branched, hyaline. 
Perithecia, smooth, spherical to ovate when mature, hyaline, 
transparent, entirely closed when young, open at top when ma-~ 
ture, 80-100 » in diameter, without stroma or subicle; wall 4 u 
thick at top, and sides, transparent, opening by apical rupture 
but without a differentiated ostiole. Asci clavate to oblong, 
cbtuse, thin-walled, numerous, originating from the pseudopar- 
enchymatous base of the perithecium, 8-spored, spores longi- 
tudinal. Paraphyses numerous, exceeding the asci, very fine, 1
