Ectomycorrhizal fungi of the genus Tuber (Ascomycota) produce hypogeous ascomata commonly known as truffles. Despite their high ecological and economic importance, a considerable gap of knowledge exists concerning the diversity of Tuber species in the eastern Mediterranean region. In the frame of this study, more than 200 Tuber collections, origina...

Type material and additional collections of 11 taxa of Gautieria described in Europe and North Africa have been studied, namely G. dubia, G. graveolens, G. morchelliformis var. globispora, G. morchelliformis var. magnicellaris, G. morchelliformis var. morchelliformis, G. morchelliformis var. stenospora, G. otthii, G. pseudovestita, G. retirugosa, G...

During the last 20 years citizen science has largely contributed at promoting knowledge about mushroom diversity in Greece. In the frame of an ongoing collaboration among amateur and professional mycologists, hundreds of specimens have been subjected to DNA sequencing, followed by phylogenetic analyses and detailed morphoanatomical examination of s...

The report describes and suggests the development of a new/updated legislative regulation for the collection, certification, and trade of Wild Edible Mushroom (WEMs) in Greece after an initiative taken by the Ministry of Environment and Energy, and the Ministry of Rural Development and Food.

A comprehensive morphological and genetic study of type material and new collections of sequestrate Russulales species formerly belonging to the genera Arcangeliella, Elasmomyces, Gymnomyces, Hydnangium, Hymenogaster, Macowanites, Martellia, Secotium and Zelleromyces is here undertaken, for the purpose of providing a complete taxonomical revision o...

Knowledge on the diversity of hypogeous sequestrate ascomycetes is still limited in the Balkan Peninsula. A new species of truffle, Tuberpulchrosporum , is described from Greece and Bulgaria. Specimens were collected from habitats dominated by various oak species (i.e. Quercusilex , Q.coccifera , Q.robur ) and other angiosperms. They are morphologi...

Data on the occurrence of macrofungi in the islands of the Aegean Archipelago are still scarce and fragmentary. Although the islands of Lesvos and Agios Efstratios (northeast Aegean Sea) are of particular biogeographic interest by serving as "land-bridge" between Asia Minor and Europe, very limited information is available regarding their fungal di...

We constructed a comprehensive phylogeny of the genus Genea, with new molecular data from samples collected in several countries in temperate and Mediterranean Europe, as well as North America. Type specimens and authentic material of most species were examined to support identifications. The molecular identity of the most common species in Genea w...

Here we revisit the species diversity within the genus Genea in Europe. Nine new species are proposed: Genea brunneocarpa, G. compressa, G. dentata, G. fageticola, G. oxygala, G. pinicola, G. pseudobalsleyi, G. pseudoverrucosa, and G. tuberculata to accommodate new collections that do not match any previously described taxa. The new species are des...

The noteworthy hypogeous fungus Stephensia bombycina is recorded for the first time for the mycota of Bulgaria and Greece. Description is provided, based upon the collected specimens, accompanied by illustrations of the macro-morphological and the microscopic features of the species.

Several samples of Delastria rosea, Fischerula macrospora and Hydnocystis piligera from the Mediterranean basin are studied, and the first molecular data of these species are reported. A colour plate showing the external morphology of their ascomata is also included.
