Neolophiostoma
Neolophiostoma Boonmee & K.D. Hyde, in Ariyawansa et al., Fungal Diversity: 10.1007/s13225-015-0346-5, [48] (2015).
Index Fungorum number: IF 551404; Facesoffungi number: FoF 00961, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on dead wood in terrestrial habitats. Sexual morph: Ascomata immersed, scattered to gregarious, partially erumpent at maturity, subglobose, unilocular, black, apically carbonaceous, with wide papilla, ostiolate. Peridium composed of dark brown, carbonaceous, occluded cells. Hamathecium comprising filiform, septate, branched, pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical to subclavate, pedicellate or apedicellate, apically rounded, with an ocular chamber. Ascospores overlapping biseriate, hyaline, elongate-fusiform, narrow towards the sub-acute ends, 3–5-septate, constricted at the median septum. Asexual morph: Unknown (adapted from Ariyawansa et al. 2015).
Type species: Neolophiostoma pigmentatum Boonmee & K.D. Hyde
Notes: Neolophiostoma resembles Lophiostoma in having immersed, ascomata with minute crest-like papilla and elongate-fusiform ascospores with a thin gelatinous sheath (Mugambi & Huhndorf 2009, Hirayama & Tanaka 2011, Thambugala et al. 2015). In the phylogenetic analysis of Ariyawansa et al. (2015) based on combined LSU, SSU, RPB2 and TEF-1 sequence data, Neolophiostoma clustered with genera in Halotthiaceae hence it was accommodated in that family. Hyde et al. (2018) transferred Neolophiostoma to Phaeoseptaceae based on phylogenetic analysis of LSU, SSU, RPB2 and TEF1α sequence data. We follow Hyde et al. (2018) and treat Neolophiostoma in Phaeoseptaceae. Molecular markers available for Neolophiostoma are ITS, LSU, SSU, RPB2 and TEF1.
