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 and East Asia, and a few records of this species are reported from Azores and Africa. Its European counterpart is A. kuzyana, comb. nova, with wider pores. Infraspecific variability of A. malicola and possible gene flow between it and A. kuzyana in East Asia are detected based on tef1 sequence data. Antrodia cyclopis, sp. nova, is described as a large-spored relative of A. malicola from New Guinea. Antrodia minuta is reported here from several European countries and Siberia, and its morphological characters and host preferences are discussed. Its close relative is A. tuvensis, sp. nova, from Central Siberia, an unusual member of the group with sparse, flexuous skeletal hyphae. © 2016, 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.

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.

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 mesenterica, A. orientalis, and A. brasiliana are closely related as a monophyletic clade. However, Auricularia mesenterica has longer and narrower basidiospores (14–17 × 4.7–5.2 μm) and a distribution in Europe. A. orientalis has shorter and wider basidiospores (12.5–14.2 × 5–6 μm), and is found in China so far. A. brasiliana has hyphae distinctly inflated in KOH (up to 13 μm), the shortest basidia in the complex (30–47 × 3–5 μm), and was discovered in Brazil. Illustrated descriptions of the two new species are given based on the materials in the present study. © 2015, German Mycological Society and Springer-Verlag Berlin Heidelberg.


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.


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.
