Citation when using this data: Yuan HS et al. 2020 – Fungalpedia, Ascomycota.

Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1

Classification: Paradictyoarthriniaceae, Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi

 

Notes: The genus Paradictyoarthrinium, typified by P. diffractum, was firstly reported by Matsushima (1996). This taxon was subsequently reported by Prabhugaonkar and Bhat (2011) from palm litter from India and later by Liu et al. (2015). The genus is characterized by superficial, gregarious, black, powdery fruitbodies and macronematous conidiophores with unevenly dictyoseptate, subglobose to ellipsoid dark brown conidia. Paradictyoarthrinium includes four accepted species which are supported by both morphological and molecular data (Index Fungorum 2020). 

 

Type species: Paradictyoarthrinium diffractum Matsush., Matsush. Mycol. Mem. 9: 18 (1996)

Other accepted species: Species Fungorum – search Paradictyoarthrinium.
