Index Fungorum number: IF554539         Facesoffungi number: FoF04547

 

Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Setae 60113 × 24 μm (x̄ = 92 × 3 μm, n = 10), hyaline, aseptate, cylindrical with conical apex. Conidiophores aggregated into sporodochia, with hyaline, stiff setae around the margin of conidiomata. Conidiogenous cells 24 × 23.5 μm (x̄ = 3 × 2.5 μm, n = 20), monophialidic, hyaline, subulate. Conidia 34 × 12 μm (x̄ = 3.4 × 1.5 μm, n = 30), slimy, aseptate, hyaline, oblong, guttulate, without mucilaginous sheath.

 

Culture characteristics: Conidia germinating on MEA within 12 h. Colonies on MEA, irregular, undulate edge with curled, white, flat on media surface.

 

Habitat: Known to inhabit Saprobic on dead leaves of Pandanus sp.

 

Known distribution: Thailand.

 

Material examined: Thailand, Krabi Province, Mueang Krabi District, on Pandanus sp., 14 December 2015, S. Tibpromma SF15-030 (MFLU 16-1932, holotype; HKAS 96281, isotype); ex-type living culture, MFLUCC 16-0268 = KUMCC 17-0305.

 

GenBank Accession No: LSU: MH376741; ITS: MH388367; SSU: MH388331; TEF1: MH388401.

 

Notes: Volutella krabiense has a close phylogenetic affinity to V. thailandensis in multi-gene phylogenetic analysis. Volutella krabiense has smaller conidia than V. thailandensis (4 × 1.3 vs. 5 × 2 lm) and conidiomata of V. thailandensis lack setae. In a BLASTn search on NCBI GenBank, the closest matches of SSU sequence of MFLUCC 16-0268 is V. aeria with 99% identity to the strain CGMCC 3.17945 (KY883302).
