Skoliomycella Réblová & Hern.-Restr. gen. nov.

Etymology.

From Greek skolios (crooked, bent, or twisted) and the Latinised diminutive suffix - mycella, derived from Greek mykēs (fungus). Referring to a “ small crooked fungus ” with characteristically bent, geniculate or flexuous conidiophores observed in culture.

Type species.

Skoliomycella flava Réblová & Hern.-Restr.

Description.

Sexual morph. Not observed. Asexual morph. Colonies in vitro effuse. Mycelium composed of hyaline or lightly pigmented, septate hyphae. Conidiophores macronematous, mononematous, sometimes reduced to a single conidiogenous cell, erect, cylindrical, unbranched, flexuous to sinuous, sometimes becoming geniculate exhibiting a zig-zag pattern, percurrently elongating, pigmented, septate. Conidiogenous cells integrated, terminal and intercalary, monoblastic or polyblastic, extending sympodially, with denticles; conidiogenesis holoblastic-denticulate. Conidia solitary, dry, acropleurogenous, oblong to fusiform to ellipsoidal, pigmented, transversely septate; conidial secession schizolytic.

Notes.

Skoliomycella , typified by S. flava , known to reproduce only asexually, is proposed here as a new monotypic genus in the Tubeufiaceae . In overall morphology, it resembles Camporesiomyces ( Hyde et al. 2020; Han et al. 2025) and Zaanenomyces ( Crous et al. 2021) , which, together with Skoliomycella and several other genera, form a well-supported subclade within the Tubeufiaceae .
