Acremoniisimulans thailandensis Tibpromma & K.D. Hyde, in Tibpromma et al., Fungal Diversity: 10.1007/s13225-018-0408-6, [89] (2018)

Index Fungorum number: IF555330         Facesoffungi number: FoF04536


Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies on natural substrate consisting of erect conidiophores. Mycelium immersed in the substrate, composed of septate, branched, brown hyphae. Conidiophores 106–112 × 3– 4.5 μm (= 109 × 4 μm, n = 10), macronematous, mononematous, scattered, brown, pale brown to subhyaline at apex, smooth, thick-walled, 3–4-septate, unbranched, straight or slightly flflexuous. Conidiogenous cells 28.5– 44 × 3–4.5 μm (= 37 × 3.5 μm, n = 20), monophialidic, subhyaline, cylindrical. Conidia 5.5–8 × 3–4 μm ( = 6.5 × 3.5 μm, n = 30), solitary, pale brown to brown, oval, aseptate, rounded at each end, smooth-walled, slimy, without mucilaginous sheath.

Culture characteristics: Conidia germinating on PDA within 12 h. Colonies on PDA reaching 9 cm in 2 weeks at room temperature, circular, undulate with white to cream, raised on surface media, velvety.

Habitat: Known to saprobic on dead leaves of Pandanus sp.


Known distribution: Thailand.


Material examined: Thailand, Prachuap Khiri Khan Province, Bang Saphan District, Sai Khu Waterfall, on Pandanus sp., 30 July 2015, S. Tibpromma SF15-028 (MFLU 18-0012, holotype); ex-type living culture, MFLUCC 16-0372 = KUMCC 16-0159.

GenBank Accession No: LSU: MH260315; ITS: MH275081; SSU: MH260355.

Notes: Acremoniisimulans thailandensis is described as a unique new species based on our phylogenetic analysis where it formed a well-separated clade from other genera with high support. It has pale brown to brown, oval, aseptate conidia.
