Classification: Dictyosporiaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on rotten leaves or submerged wood. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Conidiomata on natural substratum sporodochial, superficial, punctiform to effuse, velvety, scattered to gregarious, pale brown to dark brown, olive. Conidiophores micronematous, aseptate, simple, hyaline to pale brown, smooth. Conidiogenous cells holoblastic, monoblastic, integrated, terminal, determinate, doliiform to cylindrical. Conidia acrogenous, solitary, dry, cheiroid, pale brown, smooth-walled, septate, composed of three rows of cells arising parallelly from a truncate basal cell, compactly, non-complanate, with or without appendages (Matsushima 1971; Li et al. 2017).
Notes: Pseudodictyosporium wauense is a terrestrial species collected from New Guinea. It was re-collected from submerged wood in China and described as cheiroid conidia containing three parallel rows of cells arising from a basal cell (Li et al. 2017). The parallel rows of cells of Pseudodictyosporium are similar to Vikalpa, however, phylogeny separates them as distinct genera (Boonmee et al. 2016; Li et al. 2017; Yang et al. 2018).
Type species: Pseudodictyosporium wauense Matsush.
Other accepted species: Species Fungorum – search Pseudodictyosporium.
