The comprehensive checklist of myxomycetes of Ukraine, based on extended occurrence and reference datasets.

Background: A significant body of valuable data about the myxomycetes of Ukraine lies in a "grey zone". This encompasses undigitised historical books and articles published in languages such as Polish, French or German, as well as proceedings from local conferences, articles featured in local scientific journals and annual reports submitted to public authorities by employees of protected areas, published in Ukrainian or Russian. Yet, due to their exclusive existence in print and often the Cyrillic alphabet, these publications remain neither findable nor accessible to a wider audience.

Two new species of (Geoglossaceae, Ascomycota) from south Mexico.

Two new species of are described from south Mexico based on morphological and molecular evidence. is characterized by the caespitose ascomata, rough and coiled paraphyses and the ascospores with 9-11 septa. is characterized by the capitate ascomata, clavate and straight paraphyses and the ascospores with 10-12 septa.

An overview of Estonian woodlice (Isopoda, Oniscidea).

An overview of the Estonian terrestrial isopod fauna is given, based on literature data and material collected from 1984 to 2021. The identified material consisted of 10915 specimens belonging to 14 species and collected from 172 localities throughout Estonia. In combination with previous data from the literature data, there are now reliable records of 16 species of woodlice from Estonia.

The West Palaearctic genera of Nematinae (Hymenoptera, Tenthredinidae).

Keys to adults and larvae of the genera of West Palaearctic nematine sawflies are presented. Species of some of the smaller genera are keyed, and their taxonomy, distribution, and host plants reviewed, with a geographic focus on north-western Europe, particularly Sweden. Lacourt, 2006 is a new junior subjective synonym of Latreille, 1810, resulting in the new combination (Lacourt, 2006) for the type species of .

Microsatellite based genetic diversity of the widespread epiphytic lichen (Parmeliaceae, Ascomycota) in Estonia: comparison of populations from the mainland and an island.

Understanding the distribution of genetic patterns and structure is an essential target in population genetics and, thereby, important for conservation genetics. The main aim of our study was to investigate the population genetics of , a widespread lichenised fungus, focusing on a comparison of genetic variation of its populations amongst three geographically remote and disconnected regions, in order to determine relationships amongst environmental data, variation in lichen secondary chemistry and microsatellite data in genotyped populations. In all, 928 thalli from 17 populations were genotyped using seven specific fungal microsatellite markers.

A benchmark dataset of herbarium specimen images with label data.

Background: More and more herbaria are digitising their collections. Images of specimens are made available online to facilitate access to them and allow extraction of information from them. Transcription of the data written on specimens is critical for general discoverability and enables incorporation into large aggregated research datasets.
