Saprobic on submerged marine substrates. Sexual morph: Ascomata superficial, membranous to coriaceous, light-brown to orange-brown in colour. Peridium two-layered, outer layer orange-brown, inner layer hyaline to yellow-brown. Paraphyses absent. Asci 8-spored, fusiform, unitunicate, thin-walled, early deliquescing. Ascospores filamentous, curved, hyaline, tapering at each end into an elongate, conical process or apical chamber. Asexual morph: Hyphae septate, branched, light-brown, superficial or immersed. Conidiophores present or obsolete, micronematous. Conidiogenesis is holoblastic. Conidia terminal or lateral, consist of mass of cells, gray to brown, outer cells are larger than internal conidial cells.

Notes – Schmidt (1974) introduced the genus Vesicularia, a name already occupied and therefore proposed Cumulospora (Schmidt 1985) for collections made on submerged stems of Phragmites australis, in the Baltic Sea, Germany. Subsequently, Abdullah et al. (1989) described the same taxon as Basramyces, also from Phr. australis collected from southern marshes of Iraq and was synonymized under Cumulospora (Abdel-Wahab et al. 2010). In this monograph we describe and illustrate the sexual morph of the species.

No sequences are available for the type species. A molecular study based on 18S and 28S rDNA placed two isolates from Egypt and Thailand (MF46 and GR53, respectively) in a well-supported clade with Lindra species (Abdel-Wahab et al. 2010). 

 

Type species: Cumulospora marina I. Schmidt

Other accepted species: Species Fungorum – search Cumulospora.
