The study area is the half island Sarepta, located on the territory of Krasnoarmeisky district of Volgograd. The study of the biota of fungi of the territory was held for the first time. The collection and processing of material was carried out according to the method A. S. Bondartsev and P. A. Singer. Identification of samples was carried out by standard methods in the laboratory of Experimental biology of Volgograd state University (VolSU) with the use of domestic and foreign determinants. The collected mushroom species stored in the herbarium of the VolSU. As a result of preliminary mycological studies in the period from September to November 2017 revealed 33 species of xylotrophic fungi. The greatest number of species was recorded in the ash trees and sokolnikah on wood in various stages of decomposition: the dry and dead trunks, branches, stumps. The article presents an annotated list of fungi with the indication of habitat, substrate timing, date of collection at a single discovery, the sample number in the Mycological herbarium of the VolSU and the name of the collector, if the collection was not carried out by the authors. Species names are arranged alphabetically and are aligned with the international electronic database CABI «IndexFungorum» (www.indexfungorum.org) as of February 2018.

First records of Myxomycetes for the Republic of Belarus, Basidiomycetes for the Novosibirsk and Volgograd regions, the Republic of Altai, lichens and lichenicolous fungi for the Tver Region, the republics of Altai and Tyva, bryophytes for Novaya Zemlya, the Pskov, Tula and Saratov regions, the Republic of Ingushetia, the Khanty-Mansi Autonomous Area — Yugra, the Republic of Buryatia, the New Siberian Islands Archipelago, the Peninsula and excluded lichens for the Republic of Altai are presented. Data on localities, habitats, substrates and herbarium specimens of all species are provided.

For the first time, ecologically pure A4 and A5 paper was obtained from aphyllophoroid fungi. Classical methods of mycological research and methods of creating paper web were used.

Мета-вивчити структуру інфекцій, викликаних представниками роду Candida, проаналізувати чутливість до сучасних антимікотиків. Використовували бактеріологічні, мікроскопічні і статичні методи досліджень. Одержані результати: встановлений видовий склад грибів роду Candida. Показано, що із сучасних антимікотиків найефективнішим виявився ехінокандин. Результати представляють інтерес для клінічної практики, бо нададуть можливість запобігти подальшій хронізації мікотичної інфекції. Ключові слова: кандидоз, кандиди, антимікотики. The purpose of the work is to study the etiological structure of infections caused by the genus Candida, and to analyze the sensitivity of isolated strains to modern antifungals, which are most widely used in clinical practice. The work used bacteriological, macroscopic and static methods of research. The results obtained and their novelty: the species composition of yeast-like fungi of the genus Candida, isolated from clinical material, was established. It is shown that echinocandin, the caspofungin, which inhibited the growth of Candida albicans by 92.7%, was the most effective antifungal agent, and C. krusei, C. glabrata and Candida spp.in 100% of cases. The most resistant yeast-like fungi of the river Candida were to derivatives of triazolefluconazole and intraconazole. The percentage of susceptible C. albicans strains to these antifungals did not exceed 50.5 and 54%, respectively, and the species C. krusei, C. glabrata and Candida spp.showed absolute resistance to both drugs. This work is interesting for medical microbiologists and clinicians. The present results have considerable practical interestas its will allow to adjust the treatment regimen and prevent the chronization of the process of mycotic infection.

An analysis of the biota of the aphyllophorales mushrooms carried out in the territory of the Volga-Akhtuba floodplain natural park within the Volgograd region. Based on the results of the conducted researches, 170 species of the study group are noted in the park. The great majority of identified species are saprotrophs on dead fallen wood. The largest number of species was found on Quercus robur, Populus alba, P. nigra и Fraxinus lanceolata. The largest number mushrooms ecological groups for moisture are mesophiles and xerophiles, which is typical for the arid zone.
