The review is devoted to the taxonomic representation of the order Cantharellales in connection with problems of taxonomical history of the group and problems of its ecological diversification. The history of the taxonomy of Cantharellales is considered, and it is shown that at present the order is limited to no more than 550 species from 31 genera and 5 families: Aphelariaceae (Aphelaria, Phaeoaphelaria, Tumidapexus); Botryobasidiaceae (Botryobasidium with anamorphs, Suillosporium); Ceratobasidiaceae (Ceratoporia, Ceratobasidium pr.p., Rhizoctonia); Hydnaceae (Bergerella, Bryoclavula, Bulbilla, Burgella, Burgellopsis, Burgoa, Cantharellus, Clavulina, Craterellus, Gloeomucro, Hydnum, Ingoldiella, Membranomyces, Minimedusa, Multiclavula, Neoburgoa, Parastereopsis, Repetobasidiellum, Rogersiomyces, Sistotrema, Sistotremella); and Tulasnellaceae (Pseudotulasnella, Stilbotulasnella, Tulasnella). The unresolved problems of the Cantharellales taxonomy are discussed. The ecomorphological and ecological-trophic diversification of the order is consi-dered. A synopsis of families and genera is given with identification keys and detailed original taxa diagnoses down to the generic level. It is concluded that, during the evolution of the order Cantharellales and other large groups of Agaricomycetes, there is a parallelism associated with the development by fungi of similar adaptive zones that opened up in connection with the Early Cretaceous diversification of the terrestrial biota: the co-lonization of wood debris with the formation of hypochnoid, corticioid, and secondary resupinate forms; fo-rest litter with the formation of clavarioid and ramarioid forms; the development of sporulation within grasses with a reduction of cantharelloid and secondary formation of clavarioid forms; the formation of ectomycorrhizae and orchid mycorrhiza by lignotrophic fungi; and colonization of moss protonemata, films of aerophytic algae, and lichen thalli.

The species richness and composition of macro- and microfungi on vine species in the parks of Ekaterinburg City (the Ural macroregion, Russia) located in the southern boreal vegetation subzone in a continental climate was studied. The average annual air temperature has increased by 3.1 °C since the beginning of the 20th century; therefore, the conditions for the growth of vines have improved. These conditions include warmer winters and, consequently, less frost damage to perennial plants. Due to the warmer climate, the area of vines grown in the city has increased five times over half a century, and the yield of grapes has grown 3.7 times. The alien East Asian vines are the most dominate vine species cultivated, while European, North American, and native plant species, including archaeophytes, together only represent a handful of the species cultivated. At the same time, 65% of the area of woody vines in the city is covered by a North American species, namely Parthenocissus quinquefolia. An increase in the number of vine species, their biomass, and covered areas contributes to an increase in the number of fungal species growing on these vine species. In total, 81 species of phytopathogenic and 87 species of saprobic macro- and microfungi have been recorded during the century-long history of mycological research in Ekaterinburg City. Mycobiota of vines in Ekaterinburg City is biogeographically heterogeneous and 1.1–3.2 times richer in comparison with ones of the regions located on the northern limit of natural ranges of the vines. Recorded macrofungi (Basidiomycota) are predominantly present on native boreal species; however, some exotic tropical and subtropical East Asian fungal species (that have not ever been recorded on other substrates in the natural forests of the Urals and Siberia) are found here too. Recorded microfungi are highly specialized vine-associated species (mainly Ascomycota) that are widespread within the natural ranges of the vines and absent in the boreal zone of Eurasia: there are 63 vine-associated species (15 macro- and 48 microfungi) in Ekaterinburg that are not found in the Urals on other substrates. Many of these species have been recorded for the first time in this study, so we consider that they invaded Ekaterinburg City in the last 20 years, likely due to the warming climate observed over the last decades in the region. There are 19 and 32 species of phytopathogenic fungi collected in the families Cucurbitaceae and Vitaceae, respectively. During the past 40 years, the recorded fungal species richness has increased by 16% on Cucurbitaceae, as well as 37% on grapes. In this study, the distribution of vine-associated fungi, including phytopathogenic fungal species, from the nearest regions of ancient vine culture (Southern European Russia and the Caucasus, Central Asia, the south of the Russian Far East) to the boreal regions of the Urals were investigated. The increase in the range of these phytopathogenic fungal species can lead to significant economic losses to the regional agricultural sector.

The present review highlights the chitin/chitosan as biopolymers that are promising for biomedical research development. Our goal was to assess the potential for practical use of these biopolymers and to summarize information on traditional and innovative technologies for their production and purification. The widespread occurrence of chitin and chitosan in nature as well as the unique chemical and biological properties of chitosan are reasons of growing interest in the use of the latter in several pharmaceutical fields. The main stages of chitin extraction and its further modification into chitosan are deproteinization, demineralization, deacetylation, and the main methods of chitosan purification are filtration, dialysis and reprecipitation. The profitability of the production of chitin/chitosan from crustaceans and edible mushrooms is approximately at the same level. The cost of mushroom products can be reduced by using agricultural or forestry waste as nutrient substrates. This makes the use of fungi as sources of chitin/chitosan in forested regions a rather promising issue.

A review of research field related to well-known Russian medicinal fungal material, Chaga, is caused by the need to summarize information about the effects of its individual compounds on molecular targets of cancer cells. Chaga raw material (sterile bodies of the fungus Inonotus obliquus) is a complex fungus tissue which includes wood degradation products, and products of assimilation wood tissue components by the fungus. Chaga raw material is rich in polyphenols, triterpenoids of fungal and plant origin, and polysaccharides. In the early 1960s, Chaga raw material was included in the USSR State Pharmacopoeia and was recommended for use as a non-specific drug for the treatment of gastritis, stomach ulcers, polyposis, precancerous diseases and some forms of malignant tumors in cases where radiation therapy and surgical intervention are not destinated. However, large pharmacological potential of Chaga at the current moment seems to be still not realized. First of all, the multidirectional effect of various Chaga bioactive complexes on the molecular targets of the cancer cell is obvious: inhibiting cyclin-dependent kinases and proapoptotic (triterpenoids), immuno-mediated cytotoxic and pro-inflammatory (polysaccharides), genoprotective and antiapoptotic (polyphenols). It is obviously that complex action of these substances on cancer tissue has less pronounced effect than the targeted one. Consequently, the clinical trials of purified bioactive complexes of chaga, primarily of proapoptotic (inotodiol, betulinic acid) and anti-inflammatory (3,4-dihydroxybenzalacetone) action, are on the agenda. Based on the data reviewed, it is suggested that careful study of Chaga raw material in the future may lead to elaboration of new and more effective pharmaceuticals
