Lentistoma

Lentistoma A. Hashim., K. Hiray. & Kaz. Tanaka

Index Fungorum number: IF823136

 

Saprobic on woody plant or submerged wood. Sexual morph: Ascomata scattered, immersed to erumpent, subglobose or conical, with ostiolar, elongate, laterally compressed neck, surrounded by a well-developed clypeus or with ostiolate, short papilla. Peridium composed of globose, brown or black cells. Pseudoparaphyses numerous, cellular, hypha-like, narrow, indistinctly septate, branching and anastomosing. Asci 8-spored, bitunicate, fissitunicate, cylindrical-clavate. Ascospores fusiform, hyaline, septate, with or without a bipolar sheath (Hashimoto et al. 2018). Asexual morph: Undetermined.

 

Type species: Lentistoma bipolare (K.D. Hyde) A. Hashim., K. Hiray. & Kaz. Tanaka

 

Notes: Lentistoma was introduced based on Massarina bipolaris K.D. Hyde (Hashimoto et al. 2018), which was collected from woody plant or submerged wood. Dong et al. (2020) introduced the second Lentistoma species which was collected from submerged wood in Thailand. (Notes from Dong et al. 2020)
