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...

Aquatic hyphomycetes play a key role in decomposition of submerged organic matter and stream ecosystem functioning. We examined the phylogenetic relationships among various genera of aquatic hyphomycetes belonging to the Leotiomycetes (Ascomycota) using sequences of internal transcribed spacer (ITS) and large subunit (LSU) regions of rDNA generated from 42 pure cultures including 19 ex-types. T...

The diversity of local Mediterranean food elements is not known in detail, but offers itself to search for new vegetables, salads, fruits and spices which could be used in to enrich diets outside their region of origin. Most amid those interesting local elements are edible wild plants and weeds. Ethnobotanical research has identified ca. 2,300 different plant and fungi taxa, which are gathered ...
