More than one fungus in the pepper pot: Integrative taxonomy unmasks hidden species within Myriostoma coliforme (Geastraceae, Basidiomycota). [PDF]
PLoS ONE, 2017 Since the nineteenth century, Myriostoma has been regarded as a monotypic genus with a widespread distribution in north temperate and subtropical regions. However, on the basis of morphological characters and phylogenetic evidence of DNA sequences of the

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens
PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1304-1321, July 2026.Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

Quantification of gene-specific methylation of DNMT3B and MTHFR using sequenom EpiTYPER®
Data in Brief, 2016 Among 272 patients undergoing a screening colonoscopy, DNA methylation of DNMT3B and MTHFR, genes encoding enzymes critical to one-carbon metabolism, was quantified in blood leukocytes using Sequenom EpiTYPER®. DNA methylation was quantified in 66 and 28 CpG sites of DNMT3B and MTHFR respectively, and conceptualized using two approaches.

The epigenetic memory of temperature during embryogenesis modifies the expression of bud burst-related genes in Norway spruce epitypes [PDF]
Planta, 2017 Epigenetic memory affects the timing of bud burst phenology and the expression of bud burst-related genes in genetically identical Norway spruce epitypes in a manner usually associated with ecotypes. In Norway spruce, a temperature-dependent epigenetic memory established during embryogenesis affects the timing of bud burst and bud set in a reproducible

MycoKeys, 2017 Recent reclassification of the Ceratocystidaceae (Microascales) based on multi-gene phylogenetic inference has shown that the oak wilt fungus Ceratocystis fagacearum does not reside in any of the four genera in which it has previously been treated.

Henry Trimen: Under‐appreciated pioneer in the typification of Linnaean plant names?
TAXON, Volume 75, Issue 3, June 2026.Abstract In 1887, Henry Trimen published a paper summarising the contents of the Hermann Herbarium, in what is now the Natural History Museum, London (BM), in terms of the plant names published by Linnaeus. Trimen referred to the Hermann specimens as types of Linnaeus's names.

Boletín de la Sociedad Argentina de Botánica, 2021 The neotypification of Opuntia australis F.A.C.Weber, basionym of Pterocactus australis (F.A.C.Weber) Backeb., is made here thanks to the discovery of Weber's personal notes about it, and of two notebooks containing respectively a drawing and a short ...

The liverwort genus Metzgeria (Jungermanniopsida) in Europe – An integrative taxonomic update
TAXON, Volume 75, Issue 3, June 2026.Abstract Species delimitation in liverworts, such as Metzgeria, is hampered by their limited morphology and hence morphologically determined specimens often turn out to belong to other taxa using molecular data. Metzgeria is a simple thalloid liverwort genus with over 100 species and a worldwide distribution. Seven species are listed to occur in Europe.

Typification of Linnaean names in the genus Passiflora (Passifloraceae)
TAXON, Volume 75, Issue 3, June 2026.Abstract Between 1753 and 1771, Carl Linnaeus described and named 30 species of passionflowers (Passiflora, Passifloraceae). As was customary at the time, he did not explicitly cite herbarium specimens that could serve as types for these species. Beginning in 1926 through 2024, 18 of the 30 Linnaean species names were typified and 2 were found to be ...

Mycotaxon, 2012 A neotype designation for Helvella fusca proposed in 1997 proves to have been erroneous because an illustration accompanying the original description was overlooked. Such illustrations normally have served as the lectotype when all known specimens of the author's taxon have been lost.
