Verruconissoli Yasanthika, Tennakoon & Wanas., sp. nov.

Index Fungorum number: IF 558479, Faces of Fungi number: FoF 12888, FIGURE 5.

Etymology – The specific epithet "soli", from Latin, refers to the soil, the substrate of which the holotype was collected.

Holotype –MFLU22-0257

 

Asexual morph: Conidiophores 20–62 × 1–3.5 µm (x̅ = 39 × 2 μm, n = 20), micronematous, mononematous, solitary, unbranched, cylindrical to sub-cylindrical, straight to slightly flexuous, hyaline to brown, smooth. Conidiogenesis cells holoblastic, determinate, and rarely intercalary. Conidia 5–11 × 3–4.5 µm (x̅ = 8 × 3.5 μm, n = 20), hyaline, obovoid, smooth becoming sub-cylindrical or ellipsoidal, slightly verruculose thick and sometimes pale brown, 1-septate and constricted at the septum at maturity. Sexual morph: Undetermined.

Culture characteristics : — Colonies on PDA at 25 °C after 7 days become 3.5 cm diam., irregular margined, velvety, dark brown, raised, grayish brown at center, reverse dark brown. Mycelium hyaline, become pale brown to brown at maturity, 1–3 µm (x̅ = 1.5 µm), smooth to verruculose, septate.

Material examined: — Thailand, Chiang Rai, 20°4'35"N,100°5'43"E, 450 m, from forest soil, 7 January 2020, W.A.E. Yasanthika (MFLU22-0257, holotype); ex-type living culture MFLUCC 22-0082; (MFLU22-0253, paratype), ex-paratype living culture MFLUCC 22-0090.
