Two new species of (Hymenochaetales, Basidiomycota) from southern China based on morphological characters and molecular evidence.

MycoKeys 2019 12;61:75-89. Epub 2019 Dec 12.

Beijing Advanced Innovation Center for Tree Breeding by Molecular Design, Beijing Forestry University, Beijing 100083, China Beijing Forestry University Beijing China.

(Hymenochaetaceae) is characterized by annual to perennial, resupinate to pileate basidiocarps, a dimitic hyphal system, presence of hymenial setae, and hyaline, thin-walled, smooth basidiospores. Phylogenetic analyses based on the nLSU and a combined ITS, nLSU and RPB2 datasets of 18 species of revealed two new lineages that are equated to two new species; grouped together with , , and with a strong support; formed a strongly supported lineage distinct from other species. The individual morphological characters of the new species and their related species are discussed. Read More

Phylogeny of the genus and taxonomic assessment of the group.

Mycologia 2019 May-Jun;111(3):423-444. Epub 2019 Apr 9.

a Beijing Advanced Innovation Center for Tree Breeding by Molecular Design , Beijing Forestry University , Beijing 100083 , China.

The genus of the Hymenochaetaceae is characterized by resupinate to pileate basidiocarps, a dimitic hyphal system with fine crystal aggregates and encrusted generative hyphae in dissepiment edge and tube trama, the presence of hymenial setae, and hyaline, thin-walled, smooth basidiospores. Members of the group are easy to distinguish from other species of because of the moderately large pores, presence of mycelial setae, and large hymenial setae. Here, we explore phylogenetic relationships among 20 species of based on examination of some 90 collections sampled worldwide. Read More

The Inocybe geophylla group in North America: a revision of the lilac species surrounding I. lilacina.

Mycologia 2018 May-Jun;110(3):618-634. Epub 2018 Jun 22.

a Department of Ecology and Evolutionary Biology , University of Tennessee , Hesler 332, Knoxville , Tennessee 37996-1610.

The Inocybe geophylla group is circumscribed based on phylogenetic analysis of DNA sequences largely sampled from North America and Europe. Twenty-nine phylogenetic species are uncovered after analysis of combined nuc 28S rDNA (28S) and RNA polymerase II second largest subunit (rpb2) DNA sequence data. Species in the I. Read More

Sparassis cystidiosa sp. nov. from Thailand is described using morphological and molecular data.

Mycologia 2004 Sep-Oct;96(5):1010-4

Department of Biology, San Francisco State University, 1600 Holloway Ave., San Francisco, California 94132.

Sparassis cystidiosa, collected recently from a primary montane cloud forest in northern Thailand is described as new. It is distinct from all others species in the genus because of the presence of hymenial cystidia, relatively large basidiospores and flabellae composed of six distinct layers of tissue. Analyses of a combined dataset of DNA sequences from three genes support its distinction and suggest that the S. Read More

Cretaceous and Eocene poroid hymenophores from Vancouver Island, British Columbia.

Mycologia 2004 Jan-Feb;96(1):180-6

Department of Biological Sciences, University of Alberta, Edmonton, Alberta, T6G 2E9 Canada.

Two fossil poroid hymenophore fragments, one from the Cretaceous Period and the other from the Eocene Epoch, are described. The permineralized specimens were obtained from marine calcareous concretions on Vancouver Island, British Columbia, Canada, and were studied using the cellulose acetate peel technique. Size and distribution of pores in the hymenophores, as well as the hyphal anatomy of the dissepiments and some hymenial elements, were examined. Read More

A phylogenetic study of the genus Cookeina.

Mycologia 2002 Jul-Aug;94(4):673-82

Harvard University Herbaria, 22 Divinity Avenue, Cambridge, Massachusetts 02138.

Cookeina, with seven recognized species, is one of the commonly encountered genera of the Sarcoscyphaceae (Pezizales) in tropical and subtropical areas around the world. Morphologically the species are distinguished by combinations of several features including ascospore shape and surface relief, presence and origin of apothecial hairs and presence or absence of gelatinous material within the cortical layer of the excipular tissue. Color of the hymenium, attributed to carotenoid pigments, is particularly variable in some collections especially those referred to as C. Read More

Genetics of speciation in the basidiomycetous genus Polyporus.

Authors:
P Hoffmann K Esser

Theor Appl Genet 1978 Nov;53(6):273-82

Deutsche Sammlung von Mikroorganismen, Göttingen, FRG.

The wood rotting basidiomycete Polyporus (subgenus Leucopori Quel.) was chosen in order to investigate by genetic parameters the validity of the classical species concept based on typological characters.Species deliminations in this genus are derived from morphological characters and depend mainly on the size of hymenial pores.
