Pseudocryptoclypeus

Pseudocryptoclypeus A. Hashim. & Kaz. Tanaka, in Hashimoto et al., Persoonia 39: 67 (2017).

Index Fungorum number: IF 819250; Facesoffungi number: FoF 08290, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Saprobic on bamboo. Sexual morph: Ascomata scattered to grouped, immersed. Ostiolar neck crest-like, elongated, laterally compressed, with less-developed clypeus. Peridium composed of compressed, rectangular, thin-walled, brown cells. Pseudoparaphyses septate, branched and anastomosed. Asci bitunicate, fissitunicate, cylindrical, 8-spored. Ascospores fusiform with acute ends, multi-septate, hyaline, smooth. Asexual morph: Conidiomata pycnidial, globose to subglobose, grouped, immersed, ostiolate. Peridium composed of rectangular, pale brown cells. Conidiophores absent. Conidiogenous cells holoblastic, ampliform to cylindrical, hyaline. Conidia cylindrical with rounded ends, hyaline, smooth, uniseptate (adapted from Hashimoto et al. 2017).

Type species: Pseudocryptoclypeus yakushimensis A. Hashim. & Kaz. Tanaka

Notes: Pseudocryptoclypeus is characterised by scattered to grouped ascomata, cylindrical, 8-spored asci and fusiform with acute ends, multi-septate, hyaline ascospores. Pseudocryptoclypeus resembles Cryptoclypeus in having less-developed clypeus in ascomata, multiseptateascospores, pycnidial conidiomata, anduniseptate, hyaline conidia (Hashimoto et al. 2017) but differs in that the former has an ascomatal peridium comprising 2 zones and holoblastic conidiogenous cells while Cryptoclypeus has 1 zone and phialidic conidiogenous cells. The ideal molecular markers to differentiate between species of Pseudocryptoclypeus are ITS, RPB2 and TEF1. Pseudocryptoclypeus is morphologically and phylogenetically a distinct genus in Lophiotremataceae with high support. Molecular markers available for Pseudocryptoclypeus are ITS, LSU, SSU, RPB2 and TEF-1.
