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 » diam., and brown 4-septate spores 45-50 

 m- long by 18-20 v- 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 /* 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 fx 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 & 

 Edano, 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 m long and 3 m in diameter; measurements of spores 

 as given do not include this beak.
