Neospadicoides Luo et al.
Index Fungorum number: IF 555652, Facesoffungi number: FoF 05425
Etymology: Referring to the genus similar to Spadicoides.
Saprobic on decaying wood. Sexual morph: Undetermined. Asexual morph: Colonies effuse, hairy, brown to dark brown. Mycelium partly superficial, partly immersed, composed of septate, branched, smooth, pale brown hyphae. Conidiophores macronematous, mononematous, solitary or in groups, erect, unbranched, septate, straight or flexuous, cylindrical, brown, paler towards the apex, smooth. Conidiogenous cells holoblastic, enteroblastic, percurrent, polytretic, integrated, terminal. Conidia acrogenous or acropleurogenous, fusiform, obovoid, septate, smooth-walled.
Type species: Neospadicoides lignicola Z.L. Luo, K.D. Hyde & H.Y. Su
Notes: Neospadicoides is morphologically similar to Spadicoides in having effuse, hairy colonies on natural substrate, mycelium composed of septate, branched, smooth hyphae, conidiophores macronematous, mononematous, erect, straight or flexuous, cylindrical, smooth, conidiogenous cells integrated, terminal and smooth conidia (Hughes 1958; Seifert et al. 2011). However, Neospadicoides differs from Spadicoides in having unbranched conidiophores and acrogenous or acropleurogenous, septate conidia while Spadicoides have branched or unbranched conidiophores, tretic conidiogenous cells and acropleurogenous, aseptate or septate conidia (Hughes 1958; Goh and Hyde 1996; Seifert et al. 2011). The phylogenetic analysis of Luo et al. (2019) showed that Neospadicoides species cluster together with good support value and form a distinct subclade from Spadicoides within Xenospadicoidaceae (Xenospadicoidales).
