Based on seven-and three-gene datasets, we discuss four alternative approaches for a reclassification of Fomitopsidaceae (Polyporales, Basidiomycota). After taking into account morphological diversity in the family, we argue in favour of distinguishing three genera only, viz. Anthoporia, Antrodia and Fomitopsis. Fomitopsis becomes a large genus wit...

In the present study, fourteen Exidia -like specimens were collected from China, France, and Australia. Based on morphological characteristics and phylogenetic analyses using the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU), four species in Exidia sensu lato , including Exidia saccharina and T...

Descriptive and illustrated presentation of a rare species from xeric mediterranean environment: Adustomyces lusitanicus found in Southern Corse.

Taxonomy of the Postia caesia complex is revised based on morphology and two genetic markers, ITS and tef1. In total, we recognize 24 species, multiplying the known species diversity in the complex. We provide descriptions for 20 temperate Northern Hemisphere taxa. Identity of the core species, P. caesia, is re-established, and a neotype from the t...

First record of the albino form of Sarcoscypha coccinea (Pezizales, Ascomycota) in the French department of Rhône. The discovery of some pure white specimens of Sarcoscypha coccinea in the south of Lyon (France), in an alluvial forest along the Rhône river, is an opportunity to present and illustrate this remarkable taxon, about 60 years after the...

We explored whether DNA-phylogeny-based and morphology-based genus concepts can be reconciled in the basidiomycete family Phanerochaetaceae. Our results show that macromorphology of fruiting bodies and hymenophore construction do not reflect monophyletic groups. However, by integrating micromorphology and re-defining genera, harmonization of DNA ph...

Taxonomy of the Ceriporia purpurea group is revised based on morphological and DNA data. Neotype is selected to settle current species concept of C. purpurea s.str. Ceriporia bresadolae is reinstated as a good species, and four new species from subtropical and temperate forests of Europe (C. torpida, C. triumphalis) and North America (C. manzanitae...

Taxonomy of the Antrodia malicola group is revised based on DNA, morphological, ecological, and geographic data. This species complex is not related to Antrodia s. str. but constitutes its own lineage within the large Fomitopsis – Daedalea clade. The A. malicola group includes five species. Antrodia malicola s. str. is distributed in North America...

Tubulicrinis incrassatus, récolté sur résineux en France, est décrit et illustré. Cette espèce du groupe des Tubulicrinis à cystides non capitées et à sommet arrondi est proche de T. calothrix et T. borealis. Les différences avec ces taxons sont commentées. Mots-clés.-Basidiomycota, corticiés, Tubulicrinis. Summary-Tubulicrinis incrassatus is descr...

Tubulicrinis incrassatus is described and illustrated from a French collection made on conifer. This species of Tubulicrinis with non capited cystidia and obtuse apex is closed to T. calothrix and T. borealis. The differences with these species are discussed.

Samples of the so-called Auricularia mesenterica complex from Europe, China, and Brazil are studied, and two new species, A. orientalis and A. brasiliana, are described from the species complex based on both morphological characters and molecular evidence. Phylogenetic analysis by combined ITS, nLSU, and rpb2 sequences shows that Auricularia mesent...

Baranowskiella ehnstromi is cited from the mountains of Vercors (Isere), Chartreuse (Savoy) and Jura (Ain). Numerous individuals of this hyper-specialized species have been recorded directly on their host fungus: Phellinopsis conchata. These new localities extend the distribution area of B. ehnstromi southward and in altitude.

Deadwood stocks and the diversity of saproxylic beetles and fungi was studied in seven stands of the alluvial forest of the Rhone river. The volumes of deadwood ranged from 22 to 184 m3/ha. The most represented trees by volume, were Poplars. Deadwood resulted from large natural collapse of mature stands driven by storms or tree-by-tree in younger s...

Baranowskiella ehnstromi est citée des massifs du Vercors (Isère), de la Chartreuse (Savoie) et du Jura (Ain). De nombreux exemplaires de cette espèce hyper-spécialisée ont été récoltés directement sur son champignon hôte : Phellinopsis conchata (Pers.) Dai, 2010. Ces stations prolongent vers le sud et en altitude l’aire de distribution de B. ehnst...

Cartilosoma rene-hentic a new Antrodia s.l. species, is described from France. It is characterized by a monomitic hyphal system localizated in the trama and by the presence of scarce skeletal hyphae in the context. This peculiar structure situates it close by Antrodia ramentacea (Berk. et Broome) Donk 1966.

A tiny heterobasidiomycete fungus is described and illustrated from a recent collection made in Lyons region (France, Rhone). The presence of myxaroid basidia allows to link this species to genus Myxarium Walk.; other characters of this collection are very close to Myxarium grilletii (Boud.) D.A. Reid. The extremely littleness of basidioma, invisib...

Ceriporia accommodates a kind of wood-inhabiting polypores producing resupinate basidiocarps and causing a white rot. More than 30 species of this genus have been described; however, only a few species were referred to molecular phylogeny. In this study, a total of 203 specimens of Ceriporia were studied morphologically, and the ITS and/or nLSU reg...

A new species is described belonging to the genus Antrodiella Ryvarden & Johansen, 1980. It grows on dead basidiomes of Trametella trogii (Berkeley) Domanski, 1968. A key is proposed for the species of Antrodiella found in France on broad-leaved trees and with elliptical basidiospores.

Bois Bouchat is a forest characteristic of the eastern foothills of the "monts du Lyonnais". The permanence of this ancient woodland site suggests that his group of fungi is representative of similar backgrounds in the nearby region. Twenty-five years of exploration allow to approach the diversity of this forest polypore. Comments provide informati...

Le bois Bouchat est une forêt caractéristique des contreforts est des monts du Lyonnais. La permanence boisée ancienne de ce lieu permet de penser que sa fonge est représentative de celle de milieux semblables dans la région proche. Vingt-cinq années de prospection ont permis d'observer la diversité des polypores de cette forêt. Des commentaires ap...

Antrodiella pirumspora, a new species living off the dead sporocarps of Trametella trogii. - A new species is described belonging to the genus Antrodiella Ryvarden & Johansen, 1980. It grows on dead basidiomes of Trametella trogii (Berkeley) Domanski, 1 968. A key is proposed for the species of Antrodiella found in France on broad-leaved trees and...

A new species of Antrodia is described in France : Antrodia pulverulenta, characterised by a resupinate basidiome which, in its natural environment, produces on itself and in proximity numerous whitish mitospores.

The polypores (Basidiomycota) occupy a special niche with their growth on the bark of a large variety of trees. The existence of polypores depends on "natural" biotopes wherein plants live and die without too much human intervention. Overexploited forests, where only profitable, healthy trees are grown are biologically dead forests. Conversely, are...

Les Polypores (Basidiomycota) occupent une niche particulière par leur vie corticole sur une grande variété de supports ligneux. L'existence des polypores est dépendante de biotopes «naturels», là où les végétaux vivent et meurent sans trop d'interventions humaines. Les forêts surexploitées, où seuls prospèrent les arbres de rapport en bonne santé,...

Une nouvelle espece a' Antrodia est decrite de France : Antrodia pulverulenta, caracterisee par un basidiome apilee qui, en milieu naturel, produit, sur lui-meme et a proximite, de nombreuses mitospores blanchâtres.

For this taxon, three shapes are retained: irpicoides (Bourdot et Galzin) Domanski, OrloS et Skirgiello, resupinata (Bourdot et Galzin) Bondartzew and a new shape called poroides. The shape albida Bondartzew is not retained.
