Paradictyoarthrinium comprises four species P. aquatica, P. diffractum, P. hydei and P. tectonicola (Index Fungorum 2020). Paradictyoarthrinium species have been reported in both terrestrial and aquatic habitats from decaying wood in freshwater, dead twig in stream, dead decaying spathe of Cocos nucifera, dead stumps and dead stem of Tectona grandis. They are known in China, India, Thailand and South Africa (Matsushima 1996, Prabhugaonkar & Bhat 2011, Liu et al. 2015, 2018a, Doilom et al. 2017).

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

Other accepted species: Species Fungorum – search Paradictyoarthrinium.
