PLEOSPORACEAE 
MERRILLIOPELTIS P. Hennings^ 
MERRiLLIOPELTIS CALAMI P. Henn. in Hedw. 47 (1908) 262. 
Alabat, back of Sangirin, Merrill 10530, December 21-30, 1916. On dead 
stems of Calamus. 
MERRILLIOPELTIS TAYABENSIS sp. nov. 
Peritheciis solitariis vel plus minusve dense maculiformiter 
dispositis, subcortice positis dein epidermide elevata et pertusa; 
pseudostromata atra, effusa, saepe conjuncta, sublenticularis, 
350-500 /X lata, 100-150 /x alta; ostiolo minutissimo, vix perspicuo, 
contextu opaco; ascis elongato-clavatis, apice valde incrassatis, 
stipitatis, 210-230 /x longis, 12-14 latis in perithecio fere 
horizontaliter dispositis; paraphysibus paucis; sporidiis plerum- 
que distichis, fusiformibus, ad medio 1-septatis, non constrictis, 
hyalinis, utrinque longe et acutissime attenuatis, 90-100 /x longis 
5-7 /X latis. 
Luzon, Tayabas Province, Basiad, Bur. Sei. 25607 Yates, December 19, 
1916. On dead stems of Calamus. 
This species is very near Merrilliopeltis hoehnelii Rehm, diifering from 
it in the size of spores and asci and in the superficial appearance of the 
perithecia which are covered by the cortical layer of the host and are 
exposed only through cracks in the latter. It agrees with Rehm’s species 
in the peculiar arrangement of the asci. 
PLEOSPORA Rabenhorst 
PLE03PORA MISCANTHIAE sp. nov. 
Culmicola, superficium culmis obtecta, velutinas, atras; myce- 
lio ex hyphis obscure brunneis 6-10 p crassis composite; perithe- 
ciis paucis, atris, laevis, 100-200 ^ diam.; ascis clavatis, 140 
p. longis, 26-32 p. crassis, octosporis, paraphysatis ; paraphysis 
filiformibus, hyalinis; sporidiis muriformibus, oblongo-fusoideis, 
hyalinis, 16-20-septatis, 60-75 p longis, 10-12 /x latis; conidiopho- 
ris erectis, 350-400 /x altis, 6-8 p latis; conidiis brunneis, 9-11- 
septatis, 75-90 x 10-12 p. 
Luzon, Bontoc Subprovince, Bur. Sci. 25231 Yates, April 19, 1916. On 
the culms of Miscanthus japopicus. 
This fungus presents a very characteristic appearance. The dead culms 
are covered by a dense velvety coating formed by the erect conidipphores. 
The perithecia are buried among and completely hidden by the conidiophores.
