On leaves of ee stiata, Porto Rico, Heller, no. 6435. 
This species is nearest to AZ. stenosfora Wint., but differs 
in the straight, not lobed or bent, capitate hyphopodia, in the 
larger, straight and more abundant mucronate hyphopodia 
and in the broader, more obtuse spores. 
Pseudomeliola (?) collapsa sp. nov. 
Parasitic on the mycelium of a Me/ziola; mycelium of slen- 
der agglutinated colorless hyphae, 214-3 yw thick; perithecia 
densely aggregated, complete, at first lenticular, soon col- 
lapsing to saucer-shape, 100-120 #4, conspicuously ostiolate, 
on radiating agglutinated hyphae that are at length closely 
septate forming a tissue of oe sae 4-5 #2 in diam- 
eter, ostiolum with the opening 8 n diameter with a 
slightly raised border which is creed with a circle of 
thread-like, closely appressed, radiating appendages which 
slightly exceed the margin of th e perithecium ; asci obovate, 
short-stipitate, 30-35 « 12 4; paraphyses not seen ; ascospores 
inordinate, cylindrical or subclavate, hyaline, conspicuously 
3-guttate, I2-I4 K 3p. 
On the mycelium of Afeliola torulosa Wint. on leaves of 
Piper peltatum, Porto Rico, Heller, no. 6400 (type), also 
Heller, no. 6401, on MMelola sp. on Mesosphaerium capi- 
tatun. 
This peculiar species is referred to the above genus with 
much doubt. The radiating prosenchymatous tissue of the 
perithecium and its conspicuous ostiolum point to a relationship 
with the Microthyriaceae rather than to the Perisporiaceae
