This work provides new information about five interesting and uncommon hypogeous fungi from Greece – Balsamia vulgaris, Geopora clausa, Hydnocystis piligera, Sclerogaster compactus and Wakefieldia macrospora. Descriptions of the five species are included based upon Greek collections, accompanied by colour macro- and microphotographs, and molecular data of four of them. On the basis of molecular results, the genus Wakefieldia seems to be closely related to Hebeloma in the Hymenogastraceae, while Geopora clausa appears to be related to Geopora in the Pyronemataceae.

Examples from the spectacular and economically important fungus genus Boletus illustrate the current state of and recent events in fungal conservation in Bulgaria. National legislation is reviewed as a base for conservation and sustainable management of fungi. The evaluation approach and application of IUCN criteria for boletes on the new national Red List are illustrated by suitable examples.

Fifty-eight species and seven varieties of fungi and one protozoan associated with Cistus spp. have been collected and studied in the Sierra Calderona Nature Reserve, Castellón–Valencia, Spain. Significant diagnostic characteristics are given for some of them. Several species that belong to Myxomycota, anamorphic fungi and Basidiomycota are of special interest: Agrocybe ochracea, Cladosporium tenuisimum, Cortinarius scobinaceus var. volvatus, var. nov., Entoloma malenconii, Gymnopus lanipes, Hebeloma plesiocistum, Inocybe amblyspora, I. splendens, Inocybe cf. squarrosa, Lindbladia tubulina, Lyophyllum cistophilum, Melanoleuca polioleuca, M. subpulverulenta, Panaeolina foenisecii, Tomentellopsis pusilla and Tulostoma macrocephalum.

Information about the first finding in Bulgaria and the Balkan Peninsula of Boletus roseoalbidus (= Xerocomus roseoalbidus) is presented. A description and illustrations are provided upon the Bulgarian collections. Cytospora sacculus on Ailanthus altissima is a new record for Bulgaria. Four ascomycetes, Hyponectria buxi, Plagiosphaera immersa, Pleuroceras pleurostylum, Pseudovalsa umbonata, are reported for the first time from Bulgaria.

Fourteen species of hypogeous fungi have been collected and studied in the province of Castellón in Spain. Significant diagnostic characters are given for some of them. Several species that belong to the Basidiomycota are of special interest: Alpova microsporus, Hymenogastser bulliardii, H. hessei, H. luteus, H. lycoperdineus, H. muticus, H. niveus and Protoglossum aromaticum (= Hymenogaster remyi).

The distribution and ecology of forty hypogeous fungi from Sicily (southern Italy) is here pointed out. Hysterangium stoloniferum, Protoglossum aromaticum, Sclerogaster compactus and Tuber maculatum are reported as new records from Sicily. Gymnomyces xanthosporus and Melanogaster umbrinigleba are also new for Italy.

Physarum galbeum is reported for the first time from Turkey. Four species of fungi are recorded for the first time from Bulgaria (Botryosphaeria visci on Viscum album, Erysiphe elevata on Catalpa bignonioides, Erysiphe flexuosa on Aesculus hippocastanum, and Scleroderma polyrhizum). Additionally, Botryosphaeria visci is a new record for Romania.

The paper provides information about the first findings in Bulgaria of four rare and noteworthy taxa of Boletus. A new combination, B. persicolor, is proposed for the accommodation of Xerocomus persicolor into Boletus. Boletus depilatus, B. luteocupreus, B. permagnificus, and B. persicolor are described and illustrated. In addition a second locality in Bulgaria is reported for B. dupainii, which is one of the candidates for inclusion of the Appendix I of the Bern Convention. The potential conservation status of the five species is briefly discussed.

This paper provides information about the distribution of 22 species of Boletales. New data are reported or confirmations of previous older records are made.

The paper provides a preliminary checklist of Boletales in Bulgaria. It includes 77 species belonging to 18 genera. For each recorded taxon the distribution throughout the country, references to literature sources as well as the collection in which herbarium specimens are kept are given.
