Sugarcane (Saccharum officinarum, Poaceae) is cultivated on a large scale in (sub)tropical regions such as Brazil and has considerable economic value for sugar and biofuel production. The plant is a rich substrate for endo- and epiphytic fungi. Black yeasts in the family Herpotrichiellaceae (Chaetothyriales) are colonizers of human-dominated habitats, particularly those rich in toxins and hydrocarbon pollutants, and may cause severe infections in susceptible human hosts. The present study assessed the diversity of Herpotrichiellaceae associated with sugarcane, using in silico identification and selective isolation. Using metagenomics, we identified 5833 fungal sequences, while 639 black yeast-like isolates were recovered in vitro. In both strategies, the latter fungi were identified as members of the genera Cladophialophora, Exophiala, and Rhinocladiella (Herpotrichiellaceae), Cyphellophora (Cyphellophoraceae), and Knufia (Trichomeriaceae). In addition, we discovered new species of Cladophialophora and Exophiala from sugarcane and its rhizosphere. The first environmental isolation of Cladophialophora bantiana is particularly noteworthy, because this species up to now is exclusively known from the human host where it mostly causes fatal brain disease in otherwise healthy patients.

It has been established that in order to get good quality grain and timely harvesting all yield along with direct combine operator usage, application of separate way during grain humidity is acceptable.

It is common practice in scientific journals to print genus and species names in italics. This is not only historical as species names were traditionally derived from Greek or Latin. Importantly, it also facilitates the rapid recognition of genus and species names when skimming through manuscripts. However, names above the genus level are not always italicized, except in some journals which have adopted this practice for all scientific names. Since scientific names treated under the various Codes of nomenclature are without exception treated as Latin, there is no reason why names above genus level should be handled differently, particularly as higher taxon names are becoming increasingly relevant in systematic and evolutionary studies and their italicization would aid the unambiguous recognition of formal scientific names distinguishing them from colloquial names. Several leading mycological and botanical journals have already adopted italics for names of all taxa regardless of rank over recent decades, as is the practice in the International Code of Nomenclature for algae, fungi, and plants, and we hereby recommend that this practice be taken up broadly in scientific journals and textbooks.

Purpose. Analysis of species and varietal diversity of the genus Salvia L. cultivated flora of the world, including Ukraine; prognostic assessment and determination of the directions of ornamental representatives of the genus introduction to the conditions of the Forest-steppe of Ukraine. Methods. Analysis and synthesis, comparison and generalization of information data, introduction forecast. Results. The modern assortment of the genus Salvia is presented in quantitative, taxonomic, arealogical and ecological-cenotic terms. Belonging of the species of the genus to 6 main centers of origin of cultivated plants was determined, and a significant diversity of life forms (nanophanerophytes, microphanerophytes, hamephites, hemicryptophytes, theophytes), naturally formed under the influence of factors determined by different geographical and ecological-phytocenotic conditions of plant growth was reflected. Species assortment of the genus Salvia from the collection fund of the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine was analyzed in comparison with the collections of other Ukrainian botanical gardens. The list of decorative species of the collection, found in the natural flora of Ukraine, was given. Three groups of species have been identified by origin, what determines the conditions for plant cultivation in the Forest-Steppe of Ukraine. In terms of taxonomic structure, introduced sage species belong to eight (according to Bentham, 1833) out of twelve sections, which represent biomorphological diversity and confirm the high introduction potential of these plants.  The species and interspecific hybrids most fully used in breeding work and represented by a significant varietal diversity were distinguished, as well as the sage assortment of the collection of ornamental plants of the NBG was presented. Conclusions. It has been revealed that the species and varietal diversity of the genus Salvia of the world cultivated flora has a significant introduction potential for the Forest-Steppe zone of Ukraine. It was determined that the main base for the introduction of the ornamental species of the genus Salvia in Ukraine is the collection of the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine. The main directions of further introduction and breeding work with representatives of the genus Salvia in the Forest-Steppe conditions of Ukraine were highlighted.

ABSTRACT True fungi (Fungi) and fungus-like organisms (e.g. Mycetozoa, Oomycota) constitute the second largest group of organisms based on global richness estimates, with around 3 million predicted species. Compared to plants and animals, fungi have simple body plans with often morphologically and ecologically obscure structures. This poses challenges for accurate and precise identifications. Here we provide a conceptual framework for the identification of fungi, encouraging the approach of integrative (polyphasic) taxonomy for species delimitation, i.e. the combination of genealogy (phylogeny), phenotype (including autecology), and reproductive biology (when feasible). This allows objective evaluation of diagnostic characters, either phenotypic or molecular or both. Verification of identifications is crucial but often neglected. Because of clade-specific evolutionary histories, there is currently no single tool for the identification of fungi, although DNA barcoding using the internal transcribed spacer (ITS) remains a first diagnosis, particularly in metabarcoding studies. Secondary DNA barcodes are increasingly implemented for groups where ITS does not provide sufficient precision. Issues of pairwise sequence similarity-based identifications and OTU clustering are discussed, and multiple sequence alignment-based phylogenetic approaches with subsequent verification are recommended as more accurate alternatives. In metabarcoding approaches, the trade-off between speed and accuracy and precision of molecular identifications must be carefully considered. Intragenomic variation of the ITS and other barcoding markers should be properly documented, as phylotype diversity is not necessarily a proxy of species richness. Important strategies to improve molecular identification of fungi are: (1) broadly document intraspecific and intragenomic variation of barcoding markers; (2) substantially expand sequence repositories, focusing on undersampled clades and missing taxa; (3) improve curation of sequence labels in primary repositories and substantially increase the number of sequences based on verified material; (4) link sequence data to digital information of voucher specimens including imagery. In parallel, technological improvements to genome sequencing offer promising alternatives to DNA barcoding in the future. Despite the prevalence of DNA-based fungal taxonomy, phenotype-based approaches remain an important strategy to catalog the global diversity of fungi and establish initial species hypotheses.
