Soil-borne Ophiostomatales species (Sordariomycetes, Ascomycota) in beech, oak, pine, and spruce stands in Poland with descriptions of Sporothrix roztoczensis sp. nov., S. silvicola sp. nov., and S. tumida sp. nov. MycoKeys (IF 3.3) Pub Date : 2023-05-16 Piotr Bilański, Robert Jankowiak, Halvor Solheim, Paweł Fortuna, Łukasz Chyrzyński, Paulina Warzecha, Stephen Joshua Taerum
Ophiostomatales (Ascomycota) contains many species, most of which are associated with bark beetles. Some members of this order are plant or animal pathogens, while others colonize soil, different plant tissues, or even carpophores of some Basidiomycota. However, little is known about soil-inhabiting Ophiostomatales fungi. A survey of these fungi associated with soil under beech, oak, pine, and spruce

Three new species of Trichoderma (Hypocreales, Hypocreaceae) from soils in China MycoKeys (IF 3.3) Pub Date : 2023-05-02 Rui Zhao, Li-Juan Mao, Chu-Long Zhang
Trichoderma spp. are diverse fungi with wide distribution. In this study, we report on three new species of Trichoderma, namely T. nigricans, T. densissimum and T. paradensissimum, collected from soils in China. Their phylogenetic position of these novel species was determined by analyzing the concatenated sequences of the second largest nuclear RNA polymerase subunit encoding gene (rpb2) and the

Morphology and molecular analyses reveal three new species of Botryosphaeriales isolated from diseased plant branches in China MycoKeys (IF 3.3) Pub Date : 2023-04-26 Lu Lin, Yukun Bai, Meng Pan, Chengming Tian, Xinlei Fan
The Botryosphaeriales represents an ecologically diverse group of fungi, comprising endophytes, saprobes, and plant pathogens. In this study, taxonomic analyses were conducted based on morphological characteristics and phylogenetic analyses of multi-gene sequence data from four loci (ITS, LSU, tef1-α, and tub2). Thirteen isolates obtained from Beijing and Yunnan Province were identified as seven

Taxonomy and phylogeny of Sidera (Hymenochaetales, Rickenella clade) from China and North America revealing two new species MycoKeys (IF 3.3) Pub Date : 2023-04-20 Zhan-Bo Liu, Hong-Min Zhou, Hong-Gao Liu, Yuan Yuan
Sidera, belonging to the Rickenella clade of Hymenochaetales, is a worldwide genus with mostly poroid hymenophore of wood-inhabiting fungi. Two new species in the genus, Sidera americana and S. borealis, are described and illustrated from China and North America based on morphological and molecular evidence. They were mainly found growing on rotten wood of Abies, Picea and Pinus. S. americana is

Two new species of genus Leucoagaricus (Agaricaceae, Agaricales) from Pakistan MycoKeys (IF 3.3) Pub Date : 2023-04-10 Shazia Ashraf, Arooj Naseer, Muhammad Usman, Abdul Nasir Khalid
The genus of basidiomycetous fungi, Leucoagaricus, occurs worldwide, from subtropical to boreal latitudes. Several collections of Leucoagaricus were made during mycological field trips conducted in different forests of Margalla, Pakistan. An integrative framework combining morphological and phylogenetic data was employed for their study. As a result, the two species La. margallensis and La. glareicolor

How, not if, is the question mycologists should be asking about DNA-based typification MycoKeys (IF 3.3) Pub Date : 2023-04-10 R. Henrik Nilsson, Martin Ryberg, Christian Wurzbacher, Leho Tedersoo, Sten Anslan, Sergei Põlme, Viacheslav Spirin, Vladimir Mikryukov, Sten Svantesson, Martin Hartmann, Charlotte Lennartsdotter, Pauline Belford, Maryia Khomich, Alice Retter, Natàlia Corcoll, Daniela Gómez Martinez, Tobias Jansson, Masoomeh Ghobad-Nejhad, Duong Vu, Marisol Sanchez-Garcia, Erik Kristiansson, Kessy Abarenkov
Fungal metabarcoding of substrates such as soil, wood, and water is uncovering an unprecedented number of fungal species that do not seem to produce tangible morphological structures and that defy our best attempts at cultivation, thus falling outside the scope of the International Code of Nomenclature for algae, fungi, and plants. The present study uses the new, ninth release of the species hypotheses
