DIMEROSPORINA v. Hoehnel 
DIMEROSPORINA DINOCHLOAE Syd. sp. nov. 
Epiphylla, maculas minutas parum perspicuas rotundatas 
2-4 mm latas tandem confluentes atro-griseas formans; subiculo 
superficiali, parce evoluto, ex hyphis brevibus cellulos (cellulis 
ca. 8-12 » longis vel latis) conidia helminthosporioidea obclavata 
4-6-septata non constricta flavidulo-fuscidula 55-75 » longa 11-14 
» lata crasse tunicata (membrana 2-3 » crassa) generantibus 
composito, fusco, ubique setis numerosis erectis rectis vel vix 
flexuosis apice semper obtusis atro-olivaceis 100-220 » longis 9-11 
» latis septatis (articulis 15-25 » longis) obsito; pycnidiis nume- 
rosis, primitus globulosis, dein obovatis, stipitatis, spermatia mi- 
nutissima hyalina 2 » longa 1 » lata includentibus; peritheciis 
eadem forma et magnitudine ac pycnidiis, pedicello brevi crasso 
5-20 » longo 5-10 » lato suffultis, primitus globoso-clausis, dein 
obovatis, et imperfecte ostiolatis, 40-50 » diam., contextu tenaci 
olivaceo-fuligineo ex cellulis 6-8 ,» diam. composito; ascis 
sporidiisque nondum maturis. 
PALAWAN, Mount Capoas, Merrill 9089, April, 1918. On leaves of Dino- 
chloa scandens; Taytay, Merrill 8736, April, 1913. On leaves of same host. 
We regret not to have seen mature perithecia. They seem to include 
more than one ascus, hence we have placed the fungus in the genus Dimeros- 
porina.
