Chemical investigation of the culture broth extracts of the marine-derived fungus Massarina sp. (strain CNT-016) has yielded two secondary metabolites, spiromassaritone (1) and massariphenone (2), as well as the previously reported fungal metabolites 6-epi-5'-hydroxy-mycosporulone (3) and enalin A (4). The structures of these compounds were established by a variety of one- and two-dimensional NMR experiments, while the relative configuration of ... Read more

The current study extends our knowledge of the biogeography of subtropical mangrove fungi from the Red Sea, which has not been well explored. Diversity of marine fungi in Red Sea mangroves in Egypt was assessed, and fungi dominating the communities were recorded and compared with those from other mangroves in subtropical and tropical regions. Intertidal decayed mangrove wood samples were ... Read more

This study extends our knowledge of the marine fungi in the Bahamas Islands (Atlantic Ocean) and of subtropical mangroves in general. Ninety-two fungal taxa have been recorded from seven mangrove sites, of which 81 are new records, bringing the total number of species for the islands to 112. Fungi dominating the community were Lulworthia grandispora, Kallichroma tethys, Leptosphaeria australiensis and ... Read more

Torpedospora and Swampomyces have not been classified into any family or order with certainty. Results, based on individual and combined analyses of the partial small and large subunit rRNA gene sequences, indicate that Torpedospora and Swampomyces form a monophyletic clade and group within the subclass Hypocreomycetidae, Sordariomycetes. Torpedospora is distantly related, morphologically and phylogenetically, to the Halosphaeriales. Swampomyces shows no ... Read more

Conidiogenesis and conidial appendage ontogeny of the coelomycete Bartalinia robillardoides Tassi was studied at the light microscope, scanning electron microscope, and transmission electron microscope levels. Conidiogenesis in B. robillardoides is holoblastic. Appendage ontogeny begins as a cellular outgrowth of the apical and the basal cells of the young conidium, the former developing prior to the basal appendage. Conidia detach from ... Read more

Decaisnella formosa sp. nov., an undescribed ascomycete, was discovered on intertidal wood from a beach on the Mornington Peninsula, National Park, Victoria, Australia. Of the eleven species described under the genus Decaisnella, none match D. formosa, which is described here as a new species.Key words: Loculoascomycetes, Melanommatales, marine fungi, muriform ascospores.

A new order is introduced (Jahnulales) to accommodate ascomycetes with stalked/sessile and dimorphic ascomata, hyphal stalk cells that are ca 40 μm wide, and ascospores that are unequally 2-celled with or without various types of appendages or sheaths. The order includes a single family, the Aliquandostipitaceae, and has affinities with the Pleosporales within the Dothideomycetes. Studies on freshwater ascomycetes in ... Read more

During a study of the intertidal mangrove fungi of Egypt, two new species of Swampomyces were found and are described here. The new species Swampomyces clavatispora differs from the other species in having clavate ascospores, while S. aegyptiacus differs from S. armeniacus and S. triseptatus in having longer and narrower ascospores. A key to Swampomyces species is provided. Read more

Trichocladium melhae, a mitosporic fungus, collected frequently on wood associated with sand in Hong Kong, Malaysia and Singapore is described as a new species. The fungus is compared with other Trichocladium species. Read more

Halosarpheia unicellularis sp. nov. is described from decayed attached wood of Avicennia 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 ... Read more
