“…Sixty-three specimens from Northern Europe, Svalbard, and North America were targeted for sequencing in this study, including the holotype of I. favrei (Bon 84095,LIP!). In addition the ITS sequence of the lectotype of I. taxocystis (JN580884) and paratype of I. rivularis (JN580885) from the study by Kokkonen and Vauras (2012), the epitype of I. praetervisa (KT201675), I. tabacina Furrer-Ziogas and I. phaeosticta Furrer-Ziogas from the study by Esteve-Ravent os et al 2016were included. Also a few additional ITS and LSU sequences of Inocybe section Marginatae published in Ryberg, Larsson, and Jacobsson (2010) were included.…”

“…Analyses of ITS sequence data have become an important tool for evaluating the morphological characters used to determine and diagnose species. This has been especially valuable for groups with morphologically similar characters and seemingly broad ecology as often encountered within Inocybe (Cripps, Larsson, & Horak, 2010;Kokkonen & Vauras, 2012;Larsson, Vauras, & Cripps, 2014;Vauras & Larsson, 2015). The ITS region is now agreed upon as the bar code marker for fungi (Schoch et al, 2012) and has been found to be suitable and to work well for delimitation and segregation of species in the majority of the Basidiomycetes (Kõljalg et al, 2013).…”

Sequence data from a broad geographical region and different habitats show that the Inocybe praetervisa clade is comprised of four closely related species. These species of section Marginatae are characterized by having nodulose spores and a stipe that is abundantly pruinose only in the upper half. Inocybe praetervisa occurs in Southern Europe in mountainous mixed coniferous forests, and is not confirmed from Northern Europe. Inocybe rivularis occurs in northern boreal forests up to the lower alpine zone, associated with Betula in moist habitats, and is not confirmed from Southern Europe. Inocybe taxocystis is confirmed as a later synonym of I. favrei. The species has a wide geographical distribution range in Europe, mainly restricted to the alpine zone and moist soils, associated with Salix herbacea. Inocybe arctica is here described as a new species. It occurs in the arctic and higher alpine zones, associated with Dryas octopetala, Salix polaris, S. reticulata and S. herbacea. All species except I. arctica are shown to have an intercontinental distribution range and are confirmed from North America. Sequence data suggest the occurrence of one additional species in the alpine zone of China. A key to the species in the I. praetervisa group is provided.

“…Recent taxonomic revisions presenting both morphological and molecular characterizations (e.g. section Rimosae sensu lato in Larsson et al 2009 and an element of section ''Cortinatae'' in Kokkonen and Vauras 2012), however, should provide helpful comparisons with North American taxa.…”

A common new species ofInocybein the Pacific Northwest with a diagnostic PDAB reaction

2013

View full text Add to dashboard Cite

A species of Inocybe common in Washington, Oregon and British Columbia is documented and described as new. The species, I. chondroderma, is characterized by these features: pileus with a fulvous disk and ochraceous to chamois margin, presence of a cortina, densely mycelioid stipe base, smooth spores and fall phenology. The most reliable and distinctive feature of the species is a blue-green or turquoise reaction in response to application of a solution of pdimethylaminobenzaldehyde (PDAB), indicating the presence of what is most likely an indole alkaloid. PDAB use provides a quick and diagnostic character easily implemented in a laboratory setting. ITS sequences from recent collections of I. chondroderma and from materials collected in the 1940s in Washington and Oregon fully match numerous mislabeled sequences from specimens in British Columbia and Oregon. The species is most closely related to an unclarified taxon from Colorado and Japan (I. cf. chondroderma) and a rare European species, I. subnudipes. Nine different species names in Inocybe and one in Hebeloma attributed to I. chondroderma based on GenBank BLASTN searches of the ITS locus match with 99-100% similarity, reinforcing concerns about taxonomic inaccuracies in public DNA sequence databases. A complete morphological description, illustrations and phylogenetic assessment are provided.
