In these notes, fifteen basidiomycete species are reported as new to Luxembourg, with some comments regarding their ecology, frequency, nomenclature or taxonomy. Among the five aphyllophoroid fungi, Bartheletia paradoxa, probably a “living fossil” like its host Ginkgo biloba, is the most striking species. Other interesting aphyllophoroid fungi are...

... Corylus, Eucalyptus, Fagus, Fraxinus, Juglans, Populus, Prunus, Sorbus, Tilia et Ulmus (Ryvarden & Gilbertson 1993). Le basidiome typique de la Dédalée du chêne est pérenne, sessile, tenace, subéreux, fortement adné. Le chapeau est largement attaché à dimidié, semi-circulaire, aplani ou légèrement convexe, chamois à brun pâle. L'hyménophore ( fig. 2) est formé de pores irréguliers, sinueux, dédaloïdes, labyrinthi- formes, allongés à presque lamellés-furqués vers la marge, à dissépiments larges de 1 à 3 mm, profondément lacérés sur les parties obliques. Dans la base de données Mycobank (http://www.mycobank.org, consultée le 29.01.2017), le genre Daedalea Pers. appa- raît comme un ...

Közleményünkben három szaprotróf gombafaj észak-magyarországi előfordulásáról szolgáltatunk adatokat. Hazánkban kevés adat áll rendelkezésre a korhadó növényi részeken élő gombafajokról. Így munkánk során új hazai előfordulását ismertetjük a fajoknak. Beszámolunk a Bartheletia paradoxa fajnak a Typhula gyrans fehér fűz (Salix alba) levelén, továbbá a Volutella ciliata páfrányfenyő (Ginkgo biloba) szubsztrátumon való meg jelenéséről. Összegzésként elmondható, hogy az adathiányos, kevésbé kutatott fajok vizsgálata is fontos a lebontó tevékenységükből és ökológiai helyzetükből adadóan. Továbbá bővítettük a hazai gombafajok listáját.
Three new species of Leucocoprinus (Lc. tephrolepis, Lc. parvipileus, Lc. domingensis) are described, based on material from the Dominican Republic and the US Virgin Islands. These species belong in the Lc. heinemannii species complex, based on their morphological and molecular characteristics. The type collection of Lc. heinemannii was sequenced, and we confirm the tropical distribution of this species originally described from Italy. We discuss the problematic taxonomy of dark-centered species of Leucocoprinus, including the application of the names Lepiota montagnei, Lepiota atrodisca, and Lepiota phaeosticta.
In these notes, thirteen agaricoid basidiomycete species are reported as new to Luxembourg, with some comments regarding their ecology, frequency, nomenclature or taxonomy. All of them live as saprotrophs. Among them, Galerina perplexa, G. discreta (on mosses), Tubaria minutalis (on bare soil), Coprinellus bisporus (on manure), Coprinopsis insignis and Panellus ringens (on wood). Furthermore, two tropical species of the genus Leucocoprinus were collected inside a building (L. lilacinogranulosus, L. cepistipes var. rorulentus). An ascomycete species of the genus Trichoglossum (provisionally named T. cf. octopartitum) is also mentioned. New stations of eight more or less common agaricoid basidiomycetes collected in the last decades are also reported, such as the winter species Meottomyces dissimulans. Some of them were simply listed in previous publications and/or not preserved as herbarium material (Lactarius obscuratus, Coprinopsis patouillardii and Lepista panaeolus for example). Finally, the Golden cup (Caloscypha fulgens) is mentioned too ; this remarkable ascomycete was rediscovered recently, more than hundred years after its first documented record.
In these notes, twenty-five basidiomycetes and one ascomycete species are reported as new to Luxembourg, with comments regarding their nomenclature, taxonomy, macro- and microscopic characteristics, including field observations. Most of these species are uncommon or overlooked and were recorded, for the most part, during habitat-specific surveys, including Alder swamps or wet areas (Alnicola striatula, Cystolepiota adulterina), a Reed marsh (Mycena belliae), a Nardus grassland (Hygrocybe helobia, Entoloma caesiocinctum), calcicolous or unimproved grasslands (Mycenella salicina, Geoglossum fallax), semi-natural broadleaved forests (Cortinarius vaginatopus, Flammulaster limulatus) or coniferous forests (Cortinarius emollitoides). Three tropical species were also found, among which Panaeolus antillarum (on horse dung) and Leucocoprinus heinemannii (in a plant pot in a hospital). Lastly, Cheimonophyllum candidissimum for which the first record in Luxembourg dates back to 1995, was observed again.
In these notes, one hyphomycete, one ascomycete and twenty-five basidiomycete species are reported as new to Luxembourg, with comments regarding their ecology, frequency, nomenclature or taxonomy. The hyphomycete species Nodulisporium cecidiogenes lives as a parasite on Coniophora puteana, a corticioid fungus; the ascomycete species Pithya vulgaris is a cup fungus growing on dead branches of firs (Abies). Most of the basidiomycete species (eighteen) are agaricoid and are either mycorrhizal (e.g. Cortinarius argutus, C. saniosus and Inocybe fulva), saprotroph on soil or litter (Conocybe inocybeoides and Lepiota ochraceofulva) or lignicolous (Crepidotus crocophyllus and Psathyrella silvestris). The remaining seven basidiomycete species are aphyllophoroid; they include Elmerina caryae (a heterobasidiomycete), Neofavolus alveolaris (a polypore), Aleurobotrys botryosus and Dendrothele tetracornis (both corticioid), which are also known to be thermophilous. Among the newly found agaricoid fungi, eleven species were collected during the survey of a strict forest reserve (financed by Luxembourg’s national Nature and Forestry Agency), including Cystoderma superbum, which had not been seen for twenty years.
