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, areas of several hundred square metres, unexploited as they are often private, are of great biological richness. Rhone-Alpes, as a consequence of great climatic variability and woodland diversity, is particularly rich in polypores: 260 species recorded, 81% of the French fauna. Here are found polypores of northern Europe throughout the alpine zone and the mountains of upper Forez, with southern species in southern Drôme and Ardèche. The increase in population density seems to be linked to climatic and related factors: increased temperature, spore dispersal by wind and an abundance of windblown trees following the 1999 hurricane. The attention of institutional managers is drawn to the need to protect biotopes essential for biodiversity and to the urgent need to train young researchers and taxonomists in mycology.

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 regions from 42 samples, representing 18 species, were sequenced for phylogenetic analysis. Based on both morphological and phylogenetic analyses, three new species of Ceriporia, C. bubalinomarginata, C. pseudocystidiata and C. variegata, are described and illustrated. An annotated identification key is provided for all 20 species of this genus thus far known in China. Our phylogeny shows that (1) Ceriporia is not monophyletic, (2) C. spissa and C. viridans as morphologically circumscribed are polyphyletic, (3) C. inflata is retained for both C. inflata and C. jiangxiensis, and (4) presence or absence of hymenial cystidia is not a useful character in delimiting species relationships in Ceriporia. © 2013 German Mycological Society and Springer-Verlag Berlin Heidelberg.

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 information about flagship or rare species.
