In Greece, the study on the diversity and distribution of underground mushrooms is still incomplete. Little is known about the species that occur in our country, which forest species they associate with, their season of appearance and their rarity. In this paper, we present a summary of the underground mushrooms belonging to the phylum Ascomycota,...

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...

Two new tricharinoid species, Paratricharina confusa and Hellenicoscyphus hyalotrichus, are described and illustrated based on collections from Spain and Greece. The morphological features are compared with the most closely related species, especially Paratricharina poiraultii. A multigene analysis showing their taxonomic position is presented and...

A new species of Genea from southern Italy on the basis of morphological and genetics studies. Photographs of fresh specimens and of microcharacters, as well as line-drawings and philogenetic tree is also provided.

Context With the term "below ground fungι" we refer to fungi that form hypogeous or semi hypogeous fruiting bodies creating mycorrhizae, a symbiotic association between a fungus and a plant. Most hypogeous fungi form mycorrhizae, with few exceptions. A spherical potato-like shape, is the most common form of below ground fungal fruitbodies, resultin...

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...

A multigene phylogenetic analysis of Genabea, Myrmecocystis and related genera in Pyronemataceae was conducted to establish genetically supported generic limits. The nuc rDNA 28S gene, translation elongation factor 1-α (TEF1) and RNA polymerase II second largest subunit gene (RPB2) significantly supported the monophyly of several distinct genera of...

Thanks to the study of the original material of Stephensia peyronelii Mattir., recently discovered in the herbarium of the university of Turin, we propose a new combination in the genus Barssia. The work is accompanied by micrographs, an old plate by O. Mattirolo and an updated key to the genus Barssia.

Most Terfezia species establish mycorrhizal symbiosis with plants from family Cistaceae, mainly with perennial and annual Helianthemum species and with trees from different phyla (Bordallo et al. 2013). The soils of desert truffles show a remarkable variability that reflects the climatic conditions in which they form. Terfezia species (or their hos...

A new species of Genea Vittad. from Greek forests of Abies cephalonica is proposed based on morphological and genetic studies. Macroscopic images of fresh specimens, as well as observations made under optical microscopes, drawings, a 28S rDNA phylogenetic tree and a small key are provided.

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...

In this work, new information is provided on five interesting and uncommon Ascomycetes of Greece: Pseudoboubovia benkertii, Leucoscypha patavina, Pithya cupressina, Pulvinula archeri and Sowerbyella radiculata. The presentation consists of descriptions of the above specimens, which were collected in different Greek areas, and is accompanied by illu...

Two new species of Terfezia, Terfezia grisea and Terfezia cistophila, are documented from Spain and Greece, based on morphology and ITS-rDNA sequence data. Macro and micro descriptions with illustrations and ITS phylogenetic data for the two species are provided, which are discussed in relation to similar species in this genus and their host plants...

A new species of Barssia (Helvellaceae) is described from Greece based on morphological and genetic studies. Macroscopic images of fresh specimens, as well as observations made under optical microscopes, drawings and a 28S nLSU phylogenetic tree are provided.
