Description: The uptake ability toward arsenic(V), chromium(VI), and boron(III) ions of ad hoc functionalized magnetic nanostructured devices has been investigated. To this purpose, ligands based on meglumine have been synthesized and used to coat magnetite nanoparticles (Fe3O4) obtained by the co-precipitation methodology. The as-prepared hybrid material was characterized by infrared spectroscopy (IR), X-ray diffraction, thermogravimetric analysis, and scanning electron microscopy combined with energy-dispersive X-ray analysis. Moreover, its magnetic hysteresis properties were measured to evaluate its magnetic properties, and the adsorption kinetics and isothermal models were applied to discern between the different adsorption phenomena. Specifically, the better fitting was observed by the Langmuir isotherm model for all metal ions tested, highlighting a higher uptake in arsenic (28.2 mg/g), chromium (12.3 mg/g), and boron (23.7 mg/g) sorption values if compared with other magnetic nanostructured materials. After adsorption, an external magnetic stimulus can be used to efficiently remove nanomaterials from the water. Finally the nanomaterial can be reused up to five cycles and regenerated for another three cycles.

Description: A new subspecies of the African species Spermacoce bequaertii is described and illustrated. This new subspecies (subsp. brevituba) is restricted to the Kasai district in the Democratic Republic of Congo, and differs from the typical subspecies in having smaller mature flowers with a glabrous corolla tube inside.

Description: Type material and additional collections of 11 taxa of Gautieria described in Europe and North Africa have been studied, namely G. dubia, G. graveolens, G. morchelliformis var. globispora, G. morchelliformis var. magnicellaris, G. morchelliformis var. morchelliformis, G. morchelliformis var. stenospora, G. otthii, G. pseudovestita, G. retirugosa, G. trabutii and G. villosa. At the same time, morphological and genetic studies on recent and herbarium collections from several European countries have been carried out. This enabled clarification of sections within Gautieria and differentiation of 28 taxa, of which 21 are new to science. However, the deeper relationships and nomenclature changes related to the phylogenetic position of the genus Gautieria within Gomphaceae will not be addressed in this study because they would require a more complete molecular analysis together with that of related genera, e.g., Gomphus, Turbinellus, and the four subgenera of Ramaria. In addition, a lectotype for G. villosa var. villosa and reference specimens for G. graveolens and G. morchelliformis var. morchelliformis are selected, and the new combination G. morchelliformis var. dubia is proposed. Detailed descriptions, macro- and microphotographs and distribution maps of all taxa are provided, as well as extensive information on their ecology, chorology and phylogeny. A key is included to facilitate identification of taxa.

Description: A revision, based on morphological and multigene analysis, of the Clitocella species currently present in Europe is provided. Portions of nrITS rDNA, nr28S rDNA (LSU), RNA polymerase II second largest subunit (RPB2), translation elongation factor 1-alpha (EF-1α), and ATPase subunit 6 (ATP6), were used to sort out the relationships of the species within the genus. Three subgenera were recognized: Clitocella subg. Clitocella encompassing C.popinalis, C.colorata, C.mundula, C.nigrescens, C.obscura and the new species C.solaris from Switzerland; the new Clitocella subg. Paraclitopilus including C.fallax and C.blancii; and the new Clitocella subg. Rhodopleurella for accommodating C. termitophila, a peculiar entity characterized by a pleurotoid habit and growing on decaying, abandoned termite nests in the Dominican Republic. Clitocella colorata originally described from China is here reported and described for the first time in Europe (Italy and Estonia). Rhodocybe cupressicola and Clitopilus ammophilus are reduced to later synonyms of Rhodopaxillus nigrescens; similarly, Clitopilus amarus is treated as a later synonym of Omphalia fallax while Rhodocybe amarella and R. ochraceopallida of Rhodopaxillus blancii. Finally, Austrian and Swedish herbarium collections identified as Rhodocybe, a doubtful taxon considered by several modern authors occasionally as either a similar but distinct species from R.popinalis or as a dwarfish, puny and odourless form of R. popinalis, have been proved to be R. tugrulii, a species recently described from Turkey and Estonia, and also later reported from Italy and USA.

Description: Arthroderma is the most diverse genus of dermatophytes, and its natural reservoir is considered to be soil enriched by keratin sources. During a study on the diversity of dermatophytes in wild small rodents in the Czech Republic, we isolated several strains of Arthroderma. To explore the diversity and ecological significance of these isolates from rodents (n = 29), we characterised the strains genetically (i.e., sequenced ITS, tubb and tef1α), morphologically, physiologically, and by conducting mating experiments. We then compared the rodent-derived strains to existing ITS sequence data from GenBank and the GlobalFungi Database to further investigate biogeography and the association of Arthroderma species with different types of environments. In total, eight Arthroderma species were isolated from rodents, including four previously described species (A. crocatum, A. cuniculi, A. curreyi, A. quadrifidum) and four new species proposed herein, i.e., A. rodenticum, A. simile, A. zoogenum and A. psychrophilum. The geographical distribution of these newly described species was not restricted to the Czech Republic nor rodents. Additional isolates were obtained from bats and other mammals, reptiles, and soil from Europe, North America, and Asia. Data mining showed that the genus has a diverse ecology, with some lineages occurring relatively frequently in soil, whereas others appeared to be more closely associated with live animals, as we observed in A. rodenticum. Low numbers of sequence reads ascribed to Arthroderma in soil show that the genus is rare in this environment, which supports the hypothesis that Arthroderma spp. are not soil generalists but rather strongly associated with animals and keratin debris. This is the first study to utilise existing metabarcoding data to assess biogeographical, ecological, and diversity patterns in dermatophytes.

Description: A new species of Freycinetia Gaudich. (Pandanaceae; Freycinetoidea) with a lateral infructescence and \nrostrate berries each with 4\xe2\x80\x938 stigmatic remains, rarely 4, fairly common 8, mostly 5\xe2\x80\x936. The possession of rostrate \nberries places this new species in the section Devrieseella. The existence of F. wiharjae extends the distribution of the \nsection further east to mainland New Guinea, while it was previously only known from Sulawesi and the Philippines.

Description: Species in Diaporthe have broad host ranges and cosmopolitan geographic distributions, occurring as \nendophytes, saprobes and plant pathogens. Previous studies have indicated that many Diaporthe species are associated with Citrus. To further determine the diversity of Diaporthe species associated with citrus diseases in China, \nwe conducted extensive surveys in major citrus-producing areas from 2017\xe2\x80\x932020. Diseased tissues were collected \nfrom leaves, fruits, twigs, branches and trunks showing a range of symptoms including melanose, dieback, gummosis, \nwood decay and canker. Based on phylogenetic comparisons of DNA sequences of the internal transcribed spacer \nregions (ITS), calmodulin (cal), histone H3 (his3), translation elongation factor 1-alpha (tef1) and beta-tubulin (tub2), \n393 isolates from 10 provinces were identified as belonging to 36 species of Diaporthe, including 32 known species, \nnamely D. apiculata, D. biconispora, D. biguttulata, D. caryae, D. citri, D. citriasiana, D. compacta, D. discoidispora, \nD. endophytica, D. eres, D. fusicola, D. fulvicolor, D. guangxiensis, D. hongkongensis, D. hubeiensis, D. limonicola, \nD. litchii, D. novem, D. passifloricola, D. penetriteum, D. pescicola, D. pometiae, D. sackstonii, D. sennicola, D. sojae, \nD. spinosa, D. subclavata, D. tectonae, D. tibetensis, D. unshiuensis, D. velutina and D. xishuangbanica, and four \nnew species, namely D. gammata, D. jishouensis, D. ruiliensis and D. sexualispora. Among the 32 known species, \n14 are reported for the first time on Citrus, and two are newly reported from China. Among the 36 species, D. citri \nwas the dominant species as exemplified by its high frequency of isolation and virulence. Pathogenicity tests indicated that most Diaporthe species obtained in this study were weakly aggressive or non-pathogenic to the tested \ncitrus varieties. Only D. citri produced the longest lesion lengths on citrus shoots and induced melanose on citrus \nleaves. These results further demonstrated that a rich diversity of Diaporthe species occupy Citrus, but only a few \nspecies are harmful and D. citri is the main pathogen for Citrus in China. The present study provides a basis from \nwhich targeted monitoring, prevention and control measures can be developed.
