Pseudodictyosporium
Pseudodictyosporium Matsush., Bull. natn. Sci. Mus., Tokyo, N.S. 14: 473 (1971).
Index Fungorum number: IF 9568; Facesoffungi number: FoF 01266, 4 morphological species (Species Fungorum 2022), 4 species with molecular data.
Saprobic on submerged decayed wood in aquatic habitats. Sexual morph: Unknown. Asexual morph: Hyphomycetous. Conidiomata on natural substratum sporodochia, superficial, punctiform to effuse, scattered, sometimes coalescing, pale brown to dark brown, with or without a mucilage covering, rarely inconspicuous. Mycelium immersed, composed of septate, branched, subhyaline to pale brown, smooth-walled hyphae. Conidiophores micronematous, aseptate, simple, hyaline to pale brown, smooth. Conidiogenous cells integrated, holoblastic, terminal, determinate, doliiform to cylindrical. Conidia acrogenous, solitary, dry, cheiroid, very pale brown, smooth-walled, euseptate or distoseptate, consisting of a truncate basal cell on which three rows of cells arise parallelly and compactly with all 3 rows in different planes, with or without appendages (adapted from Li et al. 2017).
Type species: Pseudodictyosporium wauense Matsush.
Notes: Pseudodictyosporium is characterised by superficial, punctiform to effuse, scattered conidiomata, micronematous, aseptate, simple, hyaline to pale brown conidiophores, and cheiroid, very pale brown smooth-walled conidia. Pseudodictyosporium differs from Dictyosporium in having long conidiophores and heart-shaped conidia. Pseudodictyosporium is morphologically and phylogenetically a distinct genus in Dictyosporiaceae. Molecular markers available for Pseudodictyosporium are ITS, LSU, SSU, RPB2 and TEF-1.
