Type speciesPseudomassariosphaeria bromicola Phukhams., Ariyaw., Camporesi & K.D. Hyde, Fungal Divers. 75: 40 (2015).

Notes – Ariyawansa et al. (2015a) introduced Pseudomassariosphaeria to accommodate P. bromicola and P. grandispora (= Massariosphaeria grandispora). This genus is characterized by globose to erumpent or rarely superficial ascomata with a papillate ostiole covered by periphyses, cellular pseudoparaphyses, cylindrical to clavate, short pedicellate asci with an ocular chamber, fusiform to lunate, granulate ascospores with a wide mucilaginous sheath. Pseudomassariosphaeria bromicola was introduced from a dead terrestrial stem of Bromus sterilis and Pseudomassariosphaeria grandispora (Zhang et al. 2009c) is based on sequence data from a specimen collected from driftwood of Alnus glutinosa from the banks of Garonne River in France. Extensive sampling of these species should be carried out in different regions and hosts to better understand their natural classification.
