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,

Luzon, Tayabas Province, Basiad, Bur. Sci. 25607 Yates, December 19, 
1916. On dead stems of Calamus. 
This species is very near Merrilliopeltis hoehnelii Rehm, differing 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.

“Luzon, Bontoc Subprovince, Bur. Sci. 25281 Yates, April 19, 1916. On 
the culms of Miscanthus japonicus. 
' This fungus presents a very characteristic appearance. The dead culms 
are covered by a dense velvety coating formed by the erect conidiophores. 
‘The perithecia are buried among and completely hidden by the conidiophores.
