 DIMERIUM TAYABENSE sp. nov. 



Mycelio ex hyphis tenuibus ramosis subhyalinis ca. 2 n eras-

 astomatis, membranaceis, obscure brunneis, pseudoparenchyma- 

 ticis, setis paucis (6-12), brunneis, septatis, ca. 20 M longis; 

 ascis numerosis, subclavatis, octosporis, 40 x 12 /a; sporidiis 

 distichis, brunneis, ovoideo-oblongis, 1-septatis, constrictis, lo-

Luzon, Tayabas Province, Mount Binuang, Bur. Sci. 28890 Ramos & 

 Edano, May 13, 1917, parasitic on the mycelium of Meliola and Asterina 

 on the upper leaf surface of Momordica sp. 



Dimerium tayabensis appears to be growing on both the Meliola and 

 Asterina momordicae Yates. The spots formed by the combination of the 

 three fungi are black, crustaceous and about 2-3 mm diameter. The 

 Meliola is an apparently undescribed species with brown 4-septate spores, 

 40-45 x 12-15 m, and with a rather coarse irregularly branching mycelium 

 of 9-10 ti broad hyphae. The capitate hyphopodia are mostly alternate, 

 and the end cell is ovate or irregular, 12-15 ^ in diameter. No setae 

 were seen.

Luzon, Rizal Province, Antipolo, Bur. Sci. 29572 Ramos & Edano, 

 July, 1917, on leaves of Barring tonia sp. 



The material appears to be rather young and the perithecia are smaller 

 than in the type, the largest attaining a diameter of only 140 m. 



MELIOLA BATAANENSIS Syd. in Ann. Myc. 12 (1914) 551. 



Luzon, Tayabas Province, Bur. Sci. 26741 Ramos, October, 1916, on 

 leaves of Millettia. 



The present specimen is probably best referred to this species, though 

 it differs in several respects from the type. The setae are much longer 

 (500-700 ii) and occasionally forked, and the perithecia average somewhat 

 larger. The material appears to be more mature and more fully developed 

 than the type.
