Abstract
Halosarpheia unicellularis sp. nov. is described from decayed attached wood ofAvicennia marina collected from two mangrove sites in the Red Sea, Egypt. The ascomycete is compared with other marine taxa having ascospores with polar unfurling appendages. It is also compared with other marine genera with oval, round or ellipsoid hyaline, unicellular ascospores, but for which appendages have not been reported. Molecular data confirms the assignment of the fungus toHalosarpheia which forms a clade with the type speciesHalosarpheia fibrosa.
