Algae-inhabiting marine fungi represent a taxonomically and ecologically interesting group of microorganisms still largely neglected, especially in temperate regions. The aim of this study was to isolate and to identify the culturable mycobiota associated with Flabellia petiolata, a green alga frequently retrieved in the Mediterranean basin. Twenty algal thalli were collected from two different sampling sites in the Mediterranean Sea (Elba Island, Italy). A polyphasic approach showed the presence of a relevant alga-associated mycobiota with 64 taxa identified. The fungal isolates belonged mainly to Ascomycota (61 taxa), while only three Basidiomycota were detected. The phylogenetic position of sterile mycelia and cryptic taxa, inferred on the basis of LSU partial region, highlighted the presence of putative new phylogenetic lineages within Dothideomycetes and Sordariomycetes. This work represents the first quali-quantitative analysis of the culturable mycobiota associated to a green alga in the Mediterranean Sea.

“…The strain MUT 4775 was identified as Coprinellus radians and MUT 2331 as Psathyrella candolleana. The species C. radians is not new to the marine environment and was found in association with the marine sponge Dragmacidon reticulatum (Passarini et al, 2015) and with the zoanthid Palythoa haddoni (Qin et al, 2015). Species of Psathyrella occur mainly in terrestrial habitats, even though the ability to occupy uncommon niches is not rare for this genus (e.g.…”

Basidiomycota isolated from the Mediterranean Sea – Phylogeny and putative ecological roles

et al. 2018

Basidiomycota are an ecologically and taxonomically diverse fungal phylum, colonizing all terrestrial ecosystems, with 30,000 described species. By contrast, in marine habitats Basidiomycota are underrepresented when compared to the more abundant Ascomycota. Recently, we investigated the marine mycobiota mainly in the Mediterranean Sea, confirming the scarcity of Basidiomycota. However, a low rank taxonomic identification based on morphological features, proved impossible, since most of the strains remained sterile in axenic culture. Nevertheless, considering the great potential and biotechnological value of Basidiomycota, it would be useful to define their precise taxonomic placement. To this end, 34 marine Basidiomycota isolated from different marine substrates underwent molecular analyses and 123 newly generated sequences were obtained and deposited in GenBank. Sequencing of the Internal Transcribed Spacer (nrITS) regions allowed us to affiliate the 34 strains with six classes, but a lower taxonomic identification was reached with a multi-locus phylogenetic analysis.
