 Scientific Name: Syncephalis clavata

Syncephalis clavata Ho et Benny, sp. nov. Bot. Stud. 48:319-324. 2007.

 Description: Hyphae aeriae 1-2 μm. Sporangiophora recta, simplices, (75)-124-155(-163) μm im alta, basi 11.3-13.8 μm crassa, apice 7.5-10 μm crassa. Rhizoidei crassa, simple vel 2-3 lobati, nonseptati. Vesiculae obovatae, 8.8-13.8(-15) μm in diam, cum 8 merosporangiis superiorem vesiculae. Merosporangia dichotomosin ramose, 3 merosporas gignentia. Merospora doliiformis, 8-9 μm longa, 4-4.2 μm crassa. Zygosporae ignotae. (Typus: TNMF19552). Vegetative hyphae slender, creeping on the host, 1-2 μm wide. Sporangiophores hyaline, erect, simple, standing singly or in groups of two, (75-)124-155(-163) μm height, 11.3-13.8 μm in diameter at the broadest portion near the base, slightly tapering gradually upwards reaching 7.5-10 μm just below the vesicle, with a septum near the base. Rhizoids stout, short, 2-3 lobed. Vesicle not distinct, club–shaped, 8.8-13.8(-15) μm in diameter, slightly rounded above, attenuated below gradually, bearing about eight branched merosporangia on the top of the vesicle. Merosporangia branched once forming V-shaped arms, each containing 3 spores. Basal cells of the merosporangia cordate, symmetrical or asymmetrical, 8-10 × 4-5 μm, detached when mature leaving warts on top of the fertile vesicle. Merospores barrel-shaped, 8-9 × 4-4.2 μm, hyaline. Zygophoric structure not observed.

 Note: Several species of Syncephalis produce branched merosporangia and barrel-shaped merospores but S. clavata most closely resembles S. pygmae M. S. Patil & B. J. Patil which also has clavate sporangiophores without a distinct vesicle. Syncephalis pygmae, however, has shorter sporangiophores (25-30 μm), smaller merospores (4-6 × 1-2 μm), narrower sporangiophores top (7-8 μm wide), and more spores per merosporangium (4-6) (Patil & Patil, 1994). These differences merit the establishment of a new species. S. Mehrotra & Baijal, 1963. Sydowia, Ann. Mycol. Ser. II, 1.
