　Description： Sporangiophora recta, simplices, 700-790 μm im alta, basi (28-)30-47 μm crassa, apice 13.8-33 μm crassa, colore ochracea. Rhizoidei irregulariter ramose, septati. Vesiculae ovatae, (33-)40-58(-65) μm in diam, (38-)50-70(-83) μm im alta, cum pleuribus merosporangiis supra partem superiorem vesiculae. Merosporangia dichotomosin ramose, 7.5μm in diam, 55-70 μm im alta, 4-5 merosporas gignentia. Merospora cylindracea, 13-15(-17) μm longa, 5-6 μm crassa. Paries merosporangii persistens, potius crassus. Zygosporae ignotae. (Typus: TNMF19551). Vegetative hyphae slender, 1 μm in diameter. Sporangiophores simple, 700-790 μm high, (28-)30-47 μm in diam at the broadest part near the base, gradually attenuated upward, 13.8-33 μm in diam just below the vesicle, golden yellow. Rhizoids branched irregularly, with several septa. Vesicles ovoid, (33-)40-58(-65) μm in diam at the broadest part, (38-)50-70(-83) μm high, bearing merosporangia on the upper one third of the vesicle. Merosporangia branched dichotomously once or rarely twice at the base; the branches cylindrical, 7.5 μm in diam, 55-70 μm long, containing 4-5 spores; basal cells of the merosporangia cordate, symmetrical or asymmetrical, 7.5-12.5 μm in diam, 12.5-15 μm long, tending to remain on the fertile vesicle after merosporangia detached. Merospores cylindrical, 13-15(-17) × 5-6 μm in size, surrounded by a wrinkled sporangial wall remnant when mature. Zygospores not observed.

　Note： Among the species of Syncephalis, S. asymmetrica van Tieghem et Le Monnier, S. cordata van Tieghem et Le Monnier, S. intermedia van Tieghem and S. ramosa van Tieghem are closely related to S. formosana in having simple, yellow, straight sporangiophores, V-shaped branching merosporangia over the upper surface of the vesicle and heart-shaped basal cells of the branching meosporangia, but all these species have smaller spores (4-8 × 2- 4 μm in S. asymmetrica; 8-10 × 6 μm in S. cordata; 6-13 × 6 μm in S. intermedia and 6-12 μm in S. ramosa) than the present fungus (13-15(-17) × 5-6 μm). Also, two species have shorter (400-600 μm in S. intermedia; 500-600 μm in S. ramosa) and one has longer (up to 3mm in S. cordata) sporangiophores than S. formosana (700-790 μm). In addition, the spore number per branch of merosporangium are 10 in S. cordata, and 5-7 in S. intermedia, while the spore number per merosporangium is 4-6 in S. formosana. Syncephalis ramosa differs also because the merosporangia have various branching forms, which are simple, bifurcate or trifurcate at the base, bearing many branches at various heights along its length. Also S. ramosa has different spore shape (oval or globose) than the spore of S. formosana. Besides, S. asymmetrica and S. intermedia lack secondary branches (Indoh, 1962; Van Tieghem & Le Monnier. 1873; Van Tieghem, 1875, Zycha et al. 1969); thus we propose S. formosana as a new species.
