June 2, 1917, on a Meliola on the lower surface of the leaves of Leucosyke 
capitellata. 
The Meliola on which this grows appears to be an undescribed species 
having perithecia 150 to 200 p diam., and brown 4-septate spores 45-50 
p long by 18-20 p wide. The conidiophores of the Helminthosporium 
are not at all torulose. The two end cells of the spores are hyaline and 
the apex is prolonged into a beak 7-8 p long. 
HELMINTHOSPORIUM FLAGELLATUM sp. nov. 
Mycelio abundante, ex hyphis subhyalinis 2.5-4 p crassis for- 
mato ; conidiophoris numerosis, erectis, obscure brunneis, septatis 
200-300 p longis, 10 p crassis, prope apicem (50-75 p) torulo- 
sis; conidiis ad basim truncatis, 3-4 septatis, 40-50 p longis, 
10-12 p latis, brunneis, ad septa non constrictis. 
Luzon, Rizal Province, Mount Lumutan, Bur. Sci. 2980b Ramos & 
Edaho, July 2, 1917, on the sterile mycelium of a Meliola on the lower 
surface of leaves of Ardisia disticha. 
The mycelium of this species of Helminthosporium is almost hyaline, 
though certain filaments have a distinctly yellow tinge. The spores are 
mostly either 3- or 4-septate, the terminal cells being much lighter in 
color than the others. The apex is often prolonged into a hyaline beak 
or flagellum 20-30 p long and 3 p in diameter; measurements of spores 
as given do not include this beak.

cibus; conidiis globosis, castaneo-brunneis, papillatis, 3. 5-4.0 p
