  • Neptunomyces aureus gen. et sp. nov. (Didymosphaeriaceae, Pleosporales) isolated from algae in Ria de Aveiro, Portugal
    Publication . Gonçalves, Micael F. M.; Vicente, Tânia F. L.; Esteves, Ana C.; Alves, Artur
    A collection of fungi was isolated from macroalgae of the genera Gracilaria, Enteromorpha and Ulva in the estuary Ria de Aveiro in Portugal. These isolates were characterized through a multilocus phylogeny based on ITS region of the ribosomal DNA, beta-tubulin (tub2) and translation elongation factor 1 alpha (tef1-a) sequences, in conjunction with morphological and physiological data. These analyses showed that the isolates represented an unknown fungus for which a new genus, Neptunomyces gen. nov. and a new species, Neptunomyces aureus sp. nov. are proposed. Phylogenetic analyses supported the affiliation of this new taxon to the family Didymosphaeriaceae. Copyright Micael F.M. Gonçalves et al.
  • Three new species of Neocamarosporium isolated from saline environments: N. aestuarinum sp. nov., N. endophyticum sp. nov. and N. halimiones sp. nov.
    Publication . Gonçalves, M. F. M.; Aleixo, A.; Vicente, T. F. L.; Esteves, A. C.; Alves, A.
    Neocamarosporium species are typically halotolerant, being commonly found in saline environments like saline water, hypersaline soils and especially in association with halophytes. Several isolates were obtained from saline water, dead leaves of the seaweed Zostera noltii and live tissues of the halophyte Halimione portulacoides. Phylogenetic analysis based on ITS sequence data placed these isolates into three clades within the genus Neocamarosporium distinct from the currently known species. Isolates from each clade showed clear differences in conidial morphology. Three new species N. aestuarinum sp. nov., N. endophyticum sp. nov. and N. halimiones sp. nov. are described and illustrated. Our results show that the salt marsh plant H. portulacoides harbours a high diversity of Neocamarosporium species.
