Rostriconidium
Rostriconidium Z.L. Luo, K.D. Hyde & H.Y. Su, in Su, Luo, Jeewon, Bhat, Bao, Li, Hao, Su & Hyde, Mycol. Progr. 17(5): 536 (2018).
Index Fungorum number: IF 823172; Facesoffungi number: FoF 03764, 2 morphological species (Species Fungorum, 2022), 2 species with molecular data.
Saprobic on submerged decaying wood. Sexual morph: Unknown. Asexual morph: Colonies effuse on natural substrate, scattered, hairy, brown. Mycelium immersed in the substrate, composed of pale brown, septate, unbranched hyphae. Conidiophores macronematous mononematous, single, erect, septate, smooth, straight to flexuous, dark brown to black, pale pigment at apex. Conidiogenous cells monotretic or polytretic, integrated, terminal, cylindrical, dark brown. Conidia solitary, dry, pyriform when young, rostrate at maturity, dark brown to black, with a thick, black truncate scar at base and pale pigment cell above the scar, narrowly cylindrical and obtuse at apex (Adapted from Luo et al., 2018).
Type species: Rostriconidium aquaticum Z.L. Luo, K.D. Hyde & H.Y. Su
Notes: Rostriconidium was introduced by Luo et al. (2018) with R. aquaticum as type species. Rostriconidium resembles Phaeotrichoconis but is unique in having longer and wider conidiophores. Rostriconidium is morphologically and phylogenetically a distinct and well-defined genus in Torulaceae. Molecular markers available for Rostriconidium include LSU, SSU, ITS, TEF-1 and RPB2.
