Abstract Calvatia is a genus of gasteroid fungi, comprising about 47 species worldwide. In this paper we report the second worldwide occurrence of two poorly known species of Calvatia, recorded in the Cerrado biome of Brazil: C. oblongispora and C. nodulata. Detailed morphological descriptions and illustrations, including scanning electron micrographs of hyphae and basidiospores are provided, as well a discussion on their taxonomy and geographic distribution.

A taxonomic synopsis of the genus Cyanus in Turkey is presented. Cyanus hekimhanensis, C. cheiranthifolius var. purpurascens and C. reuterianus var. phrygius are proposed as new combinations. Some new synonymizations are proposed: Centaurea cana var. sultanensis with C. matthiolifolius, Centaurea pichleri var. ancyrensis with C. pichleri, Centaurea cana f. fulgens with C. triumfettii. Cyanus akcadaghensis is a synonym of C. matthiolifolius, Cyanus ermenekensis is a synonym of C. reuterianus, Cyanus banchevae is a synonym of C. thirkei. Lectotypes are designated here for ten accepted or synonymed names. The recognized taxa, the relevant synonyms, type details, lists of specimens examined, and a taxonomic key are provided for this genus in Turkey. In addition, the geographic distribution of all the taxa recognized in Turkey is presented and mapped.

Pesticides are a large and heterogenous group of chemicals with a complex geographic distribution in the environment. The purpose of this study was to explore the geographic distribution of pesticides in Danish drinking water and identify potential patterns in the grouping of pesticides. Our data included 899,169 analyses of 167 pesticides and metabolites, of which 55 were identified above the detection limit. Pesticide patterns were defined by (1) pesticide groups based on chemical structure and pesticide–metabolite relations and (2) an exploratory factor analysis identifying underlying patterns of related pesticides within waterworks. The geographic distribution was evaluated by mapping the pesticide categories for groups and factor components, namely those detected, quantified, above quality standards, and not analysed. We identified five and seven factor components for the periods 2002–2011 and 2012–2018, respectively. In total, 16 pesticide groups were identified, of which six were representative in space and time with regards to the number of waterworks and analyses, namely benzothiazinone, benzonitriles, organophosphates, phenoxy herbicides, triazines, and triazinones. Pesticide mapping identified areas where multiple pesticides were detected, indicating areas with a higher pesticide burden. The results contribute to a better understanding of the pesticide pattern in Danish drinking water and may contribute to exposure assessments for future epidemiological studies.

Anoplocaryum (Boraginaceae), a small genus previously known from Russia and Mongolia, is newly recorded from China. The specimen was discovered in the rock crevices of Zhangjiakou City, Hebei province, China, and was identified as A. helenae Volot. based on both morphological and molecular data. This study updates our knowledge on the geographic distribution of the genus Anoplocaryum. Two taxonomic keys were provided to distinguish Anoplocaryum and Chinese related genera, also to index taxa in Anoplocaryum.

Relevance. Tick-borne relapsing fevers caused by Borrelia species pathogenic for humans are not well understood. Aim of this review is to assess the genetic diversity of Borrelia with special attention to the relapsing fever group and phylogenetically related species carried by ticks. The review also provides up-to-date information on the main vectors and their geographic distribution, reservoirs of borrelia – pathogens, and potential pathogens of tick-borne recurrent fevers. Conclusions. New types of Borrelia, including a candidate, of relapsing fever clade and related phylogenetic lines/groups, which are carried not only by argasid, but also by solid-body ixodids ticks, deserve further study. The preservation of the epidemic potential of tick-borne relapsing fever can be facilitated by climatic changes, and poorly studied adaptation mechanisms of Borrelia to the range of vectors.
