Safagamyces marinus gen. et sp. nov. was recorded from decaying stem of Phragmites australis inside Safaga mangrove is described and illustrated in this article. Phylogenetic analyses of SSU and LSU rDNA sequences dataset placed the new fungus as a distinct branch basal to a node that contains the three asexual marine genera: Cirrenalia, Cucurbitinus and Pseudolignincola in the family Halosphaeriaceae. The fungus is characterized by straight or slightly curved, branched, smooth, 2-6 septate conidia and the sympodial conidial proliferation. Conidial cells increase in size and pigmentation from hyaline at the base to dark-brown at the apex. The new taxon is compared with other asexual fungi in Halosphaeriaceae.

A new species, Chaetopsina aquatica, collected from the River Nile, Sohag, Egypt, is described and illustrated. Phylogenetic analyses of the combined ITS and LSU rDNA placed the new species within Chaetopsina as a phylogenetically distinct species. Chaetopsina aquatica formed a basal clade to a node containing C. aurantisalinicola and C. penicillata. The new species is characterized by its longer conidia (20–35.2 × 5–8.5 μm on natural substrate, 27.5–41.5 × 5–7 μm in culture) than those reported in Chaetopsina species.
