Neolentithecia
Neolentithecia C. Phukhams., K.D. Hyde & Y. Li, in Hyde et al., Mycosphere 12(1): 1101–1156 (2021).
Index Fungorum number: IF 558399; Facesoffungi number: FoF 09841, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on dried twigs. Sexual morph: Ascomata solitary, gregarious, scattered, immersed, as shiny, black, dots visible on the host surface, uniloculate, coriaceous, ostiolate. Ostioles central, black. Peridium thick, multilayered, of cells arranged in textura angularis, brown to dark brown, inner layer lined with sub-hyaline cells of textura angularis. Hamathecium composed of numerous, cellular pseudoparaphyses, with distinct septa, anastomosing at the apex. Asci 8-spored, bitunicate, clavate, with furcate pedicel, apically rounded, with well-developed ocular chamber. Ascospores biseriate, hyaline to yellowish-brown, oval or obovoid, ends rounded, muriform, constricted at the septa, with or without a mucilaginous sheath. Asexual morph: Unknown (adapted from Hyde et al. 2021).
Type species: Neolentithecia changchunensis C. Phukhams., K.D. Hyde, W.X. Su & Y. Li
Notes: Neolentithecia is characterised by solitary, gregarious, scattered ascomata, clavate asci with furcate pedicel and hyaline to yellowish-brown, oval or obovoid ascospores with or without a mucilaginous sheath. In the phylogenetic analysis of Hyde et al. (2021) based on LSU, ITS, SSU and TEF-1, Neolentithecia formed a distinct lineage close to L. aquaticum. Neolentithecia resembles Lentithecium in having globose, ostiolate ascomata with peridium cells of textura angularis, clavate asci and muriform ascospores (Wanasinghe et al. 2014, Hyde et al. 2021). Neolentithecia differs from L. aquaticum in that it occurs on woody substrate in terrestrial habitats while L. aquaticum was found from submerged wood in aquatic habitat. Neolentithecia is morphologically and phylogenetically a distinct and well-defined genus in Lentitheciaceae. Molecular markers available for Neolentithecia include LSU, ITS, SSU and TEF-1.
