Phylogeny and Taxonomic Revision of the Family (, ).

Species of are common macrofungi with a worldwide distribution. Some of them are commercially consumed, while a few others are reported as poisonous. Two genera were accepted in the family: the epigeous Gyromitra with discoid, cerebriform to saddle-shaped ascomata and the hypogeous Hydnotrya with globose or tuberous ascomata.

Phylogenetic overview of (Boletaceae, Boletales), with descriptions of six new species from China.

In this study, species relationships of the genus were studied, based on both morphological characteristics and a four-gene (nrLSU, , and ) phylogenetic inference. Thirty-five species of the genus have been revealed worldwide, forming eight major clades in the phylogenetic tree, of which twenty-four species have been found in China, including six new species: , , , , , and a new combination (Bi & Loh) Ming Zhang, N.K.

Descriptions of five new species in subgenus from China, with molecular phylogeny of s.l.

Entoloma subgenus Claudopus is widely distributed, yet the taxonomy and systematics of its species are still poorly documented. In the present study, more than forty collections of were gathered in China and subsequently analysed, based on morphological and molecular data. The results revealed first a high level of species diversity of in China and second, there is a wide ecological range regarding the substrates and the habitats ranging from temperate, tropical to subalpine locations.

The new genus is characterised by its sinuate to subdecurrent or short deccurent, usually furcate and interveined and relatively distant lamellae, dry and whitish tomentose stipe, thin-walled ellipsoid to oviod, non-constricted basidiospores and particularly elongated basidia and a ratio of basidiospore to basidium length of >5 to 8; it is close to genera and of the tribe Chromosereae, but morphologically differs from in less umbilicate basidiomata, tomentose stipe and usually longer basidia and differs from in more robust basidioma and less glutinous pileus and/or stipe surface. Phylogenetic analyses, with ITS-LSU-RPB2 data, also indicate that forms a very distinct and independent clade at the generic level.
