Beltraniella fertilis
Beltraniella fertilis Heredia, R.M. Arias, M. Reyes & R.F. Castañeda, Fungal Diversity 11: 100 (2002) Fig. X
Index Fungorum number: IF489903; Faces of fungi number: FoF 03632
Colonies on PDA pale white, reaching a diam. of 2–3 cm in 4 days at 25oC, flat and circular-shaped, pale brown, smooth at surface and produce highly branched melanized hyphae with brownish exudates in old cultures, after 16 weeks, with conidiophores forming on the mycelium; reverse light yellow to dark brown. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Mycelium mostly immersed in the substratum, composed of septate, branched subhyaline hyphae. Setae numerous, erect, straight or flexuous, unbranched, single or in small groups, thick-walled, verrucose, dark brown at the base, paler at apex, 61.7–149.8 μm long, 2.5–7 μm wide (x̅ = 113 × 4 μm, n = 30) at the base, tapering to a pointed apex. Conidiophores macronematous, sometimes setiform; single, straight, septate, partly verrucose, thick-walled to smooth-walled, 6.4–91.5 μm long, 2.3–6.5 μm wide (x̅ = 37 μm × 3.4, n = 30), sometimes branched at the apical region, dark brown to sub hyaline at the swollen base, paler and slightly tapering towards a pointed apex. Conidiogenous cells holoblastic, monoblastic to polyblastic, integrated, terminal. Conidia solitary to aggregated, acrogenous, simple, dry, straight, smooth, thin-walled, biconic, turbinate to pyriform, rostrate to pointed at proximal end, rounded at distal end, hyaline to sub hyaline, 5–15 µm long, 2–6.5 µm wide (x̅ = 10.11 × 3.97 μm, n = 30) in the broadest part.
Distribution – Atlantic forests, Brazil, Mexico, Thailand
Known hosts – Dead leaves of Mangifera indica and Parinari alvimii
Material examined – Thailand, Chiang Mai Province, Mae Tang district, Ban Pa Deng, Mushroom Research Center, N 19o 07’ 13.7”, E 98o 43’ 52,9”, 905 m, in forest soil (dominated by Dipterocarpaceae), 20th March 2019, Erandi Yasanthika, Erscm11 (MFLU 20-0506), living culture MFLUCC 20-0119.
Notes:
Beltraniella fertilis was introduced by Heredia et al. (2002) based on morphological characteristics. The sequence data for this species was provided by Lin et al. (2017) from strains which was isolated from decaying leaves collected in Thailand.
