Index Fungorum number: IF 816827; Facesoffungi number: FoF 05463,
≡ Melanopsammella gonytrichii F.A. Fernández & Huhndorf, Fungal Diversity 18: 42 (2005)
Culture characteristics – Colonies on PDA, from above: whitish gray in the center with white concentric zones at the initial stage, reaching a diam. of 2–3 cm in 7 days, becoming grayish brown, with reverse becoming grayish brown with grayish center at 25 ℃ when mature. Colony smooth to hairy at surface, effuse, raised, with circular margin, sometimes with gray to black erect, flexuous synnemata. Mycelium 2–4 μm (x̅ = 3 μm) wide, superficial, composed of septate hyphae, hyaline to sub-hyaline when immature, latter becoming branched and melanized, sporulated after 4 weeks. Sexual morph: Previously reported by Fernández & Huhndorf (2005). Asexual morph: Conidiophores 100–250 × 2–4 μm (x̅ = 175 × 3 μm, n = 20), hyaline to sub hyaline, macronematous, mononematous, solitary, septate, unbranched, percurrently 2–5 times proliferating, with monophialidic aperture at the apex, with 2–5 intercalary percurrent phialides. Conidiogenous cells phialidic, cylindrical to lageniform, each with multiple enteroblastic conidiogenous loci producing conidia. Conidia 2.5–3.5 × 2.5–3 μm (x̅ = 3× 2.8 μm, n = 20), globose to subglobose, aseptate, hyaline, with minutely rough surface.
Material examined – Thailand, Krabi Province, Khao Phanom District, Na Khao 8.3811N, 98.9286 E, in tropical forest soil, 28 April 2019, E. Yasanthika, B103 (MFLU 21-0142), living culture (MFLUCC 21-0110).
Notes –Chloridium gonytrichii was initially introduced by Réblová et al. (2016), which was previously known as Melanopsammella gonytrichii (Fernández & Huhndorf 2005). Chloridium gonytrichii seems to have cosmopolitan distribution since it has been reported from both terrestrial and freshwater habitats (Fernández & Huhndorf 2005, Wei et al. 2018, Luo et al. 2019). Balami et al. (2021) recorded Chloridium gonytrichii from soils of agricultural land in Nepal by high throughput sequencing technology. We provide the first record of soil-inhabiting C. gonytrichii (MFLUCC 21-0110) in Thailand, with morpho-molecular descriptions.
