Hyphodontia (Hymenochaetales, Basidiomycota) and similar taxa from Central Asia

Abstract

Wood-inhabiting fungi are noteworthy components of woody ecosystems that are responsible for the decomposition and turnover of wood nutrients. While the diversity and ecology of these fungi in the temperate forests has been relatively well explored, little is known on diversity of these fungi in the arid and semi-arid forest ecosystems. This is the first study on diversity, distribution, and ecology of the fungal genus Hyphodontia s.l. in the five countries of Central Asia, viz., Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. Altogether, 11 species are confirmed for the region, among which the following six species are reported for the first time from Central Asia: Hyphodontia alutaria, H. pallidula, Kneiffiella alutacea, Lyomyces crustosus, L. erastii, and L. sambuci. In addition to the morphological evidence, the identity of three species is confirmed with phylogenetic analysis based on ITS nuclear ribosomal DNA region. The spectra of known hosts for many of the studied species were expanded. An annotated species list and geo-referenced distribution maps are provided as well as notes on taxonomy, ecology, and local, regional, and global distribution. An identification key to the species of Hyphodontia s.l. recorded in arid and semi-arid regions of Central Asia is also provided.

Morphological and molecular identification of four new resupinate species of Lyomyces (Hymenochaetales) from southern China

“…The members of Lyomyces grow on dead, still-attached or fallen branches of angiosperms, on dead wooden and herbaceous stems, or occasionally on gymnosperm wood (Yurchenko et al 2017). Twentythree species are currently known in Lyomyces worldwide (Rabenhorst 1851;Karsten 1881Karsten , 1882Peck 1903;Bourdot and Galzin 1911;Cunningham 1959Cunningham , 1963Wu 1990;Hjortstam and Ryvarden 2009;Yurchenko et al 2013Yurchenko et al , 2017Gafforov et al 2017;Riebesehl and Langer 2017) and five species were recorded in China (Xiong et al 2009;Gafforov et al 2017;Riebesehl and Langer 2017).…”

“…During investigations on wood-inhabiting fungi in southern China, four additional taxa were found, which could not be assigned to any described species in Lyomyces. In this study, the authors expand samplings from previous studies (Gafforov et al 2017;Riebesehl and Langer 2017) to examine taxonomy and phylogeny of them within Lyomyces, based on the internal transcribed spacer (ITS) regions sequences.…”

New data on the diversity of lignicolous fungi in communities of Juniperus excelsa (Cupressaceae) in Bulgaria

“…General distribution. Asia (Hjortstam & Ryvarden 2004;Dai 2011;Ghobad-Nejhad 2011;Gafforov & al. 2017), Europe (Langer 1994;Bernicchia & Gorjón 2010); North America (Gilbertson 1980;Tapia & al.…”

“…2016); South America (Langer 1994;Hjortstam & Ryvarden 2008). The species is distributed in temperate and tropical regions with cold and hot seasonable climate (Gafforov & al. 2017).…”

“…The general distribution covers North America, Europe, and temperate Asia. According to data provided by Kriegelsteiner (2000) According to Gafforov & al. (2017) this saprotrophic odontoid species is well adapted to the arid and semi-arid environments.…”
