Syncephalis depressa van Tieghem et Le Monnier, Ann. Sci. Nat. 5 ser. 17: 375, pl. 25. Figs. 122, 123. 1873.
Description：
Vegetative hyphae growing over the hyphae of Backusella circina the host, white, thin, 1-1.2 μm in diam giving rise at places clusters of merosporangiophores. Merosporangiophore simple, produced singly or in a cluster up to three, 175 – 312.5 μm height, 7.5 -23.75 μm in diam at the base, gradually tapering. Rhizoids irregularly branched and septate. Head obconical, truncate, 20-30 μm in diam, funnel shaped, bearing many merosporangia in a circle around the vesicles on the top, wall smooth, colorless, conspicuous warts seen after basal cells fell off. Merosporangia differentiate into a basal cell and 2-5 cylindrical sporiferous branches, fragmenting into 8-10 spores when mature, spore cylindrical, smooth, 2.5-2.75 μm in diam, 5-7.5 μm long. Heterothallic.

Note：
This fungus possesses two distinctive characters: 1.) merosporngia produced on the periphery of the flattened top vesicle arranged in a circle, 2.) the merosporangia differentiate into a basal cell and several cylindrical sporiferous branches. The present isolate differs from the one isolated form India in not having branched sporangiophore and also, the length of sporophore are shorter than India isolate (Mehrotra d Prasad, 1964). This isolate is more closer to S. depressa from Japan (Indoh, 1962).
