A new Halosarpheia species, collected from driftwood from Hakkeijima beach, Yokohama, Japan, is described and illustrated and is compared with other species of the genus. The new fungus was growing together with its anamorph on a piece of decaying wood. SSU and LSU rDNA sequences for both morphs were 99% similar. Phylogenetic analyses of SSU and LSU rDNA sequences of ... Read more

A new genus, Gesasha Abdel-Wahab & Nagahama, and three new species therein are described and illustrated from Gesashi mangroves, Okinawa, Japan. Molecular phylogenetic analyses of the partial SSU and LSU rDNA placed the three new species into a clade distantly related to morphologically similar fungi with a high statistical support in the Halosphaeriales, Sordariomycetidae, Sordariomycetes, Ascomycota. The new genus is ... Read more

Annulatascus nilensis sp. nov., from freshwater habitats in Egypt, is described, illustrated and compared to other species in the genus. Phylogenetic analyses of its LSU rDNA sequence with similar fungi placed the new species in the genus Annulatascus (Annulatascaceae, Sordariomycetidae incertae sedis). Annulatascus nilensis is characterized by immersed ascomata with an ascomatal neck oriented horizontally to the substrate surface, asci ... Read more

The motile cells of chytrids were once believed to be relics from the time before the colonization of land by fungi. However, the majority of chytrids had not been found in marine but freshwater environments. We investigated fungal diversity by a fungal-specific PCR-based analysis of environmental DNA in deep-sea methane cold-seep sediments, identifying a total of 35 phylotypes, 12 of ... Read more

An unknown coelomycete that was collected from the River Nile and associated irrigation canals in Egypt is described. The fungus is characterized by gelatinous pearl white acervuli, a peridium that forms textura intricata, holoblastic conidia that have one basal excentric cellular appendage, and up to 3-5 sub-apical cellular attenuating appendages. Based on morphology, no described genus can accommodate this new ... Read more

Forty-eight fungi (34 Acomycota, 13 anamorphic fungi and one Basidiomycota) were collected from 141 driftwood samples collected from one sandy and one rocky beach around Yokosuka city in two seasons (summer and winter). Of these, 28 (58%) fungi are new records for Japan including 16 (33%) potentially new taxa. Thirty-six and 26 fungi were recorded from Hakkeijima and Umikaze beaches, ... Read more

Twenty-seven fungi (18 ascomycetes, 9 anamorphic fungi) were recorded from 91 driftwood samples collected from Sarushima Island, Japan. Ceriosporopsis halima, Corollospora maritima, and Halosphaeria appendiculata occurred most frequently in the fungal community. Other common fungi include: Remispora maritima, Tirispora sp., Monotosporella sp., Phoma sp., and Trichocladium achrasporum. Among the 27 fungi collected, 7 are possibly new to science. Nemania maritima ... Read more

Four new helicoid anamorphic fungi collected from marine habitats in Egypt and Japan are described. Three marine and one terrestrial Cirrenalia species along with two Cumulospora species and the four new fungi were sequenced for LSU and SSU rDNA. Phylogenetic analyses of the generated sequences, along with those from GenBank, confirmed the polyphyly of the genera Cirrenalia and Cumulospora, and ... Read more

Two new species of the genus Corollospora, namely, C. anglusa sp. nov. with its anamorph Varicosporina anglusa sp. nov. and C. portsaidica sp. nov., which were isolated from the coast of the Mediterranean Sea in Egypt, are described in this article based on morphological and molecular evidence. The two new species have one-septate ascospores. Corollospora anglusa resembles C. gracilis by ... Read more

Dipodascus tetrasporeus sp. nov. is described as a novel yeast species in the family Dipodascaceae to accommodate an isolate recovered from sediments collected on the deep-sea floor in the north-western Pacific Ocean. In the clade comprising the genera Dipodascus, Galactomyces and Geotrichum, this is the only species that forms asci that bear four ascospores. The ascospore is surrounded by an ... Read more
