The article presents the results of a detailed survey of cultivated roses growing in the European territory of Russia for their infestation by fungi of the genus Phragmidium causing rose rust disease. The main study area was the rose garden of the Peter the Great Botanical Garden of BIN RAS (St. Petersburg). A total of five wild species and 43 vari...

Basidiomycota is one of the major phyla in the fungal tree of life. The outline of Basidiomycota provides essential taxonomic information for researchers and workers in mycology. In this study, we present a time-framed phylogenomic tree with 487 species of Basidiomycota from 127 families, 47 orders, 14 classes and four subphyla; we update the outli...

The paper continues a series of publications devoted to the new finds of fungi (Ascomycota, Basidiomycota) in Sverdlovsk Region (the Middle Urals, Russia). Totally, 75 species of macro-and microfungi reported on alien and aborigine woody plants for the first time in the region. The most numerous group are alien plant pathogenic fungi (71%) developi...

Taxonomy of Pseudohydnum gelatinosum and its sister taxa is revised via morphological data and a four-gene dataset (ITS, ncLSU rDNA, TEF1, RPB1). Identity of P. gelatinosum and Tremellodon pusillus is re-established based on newly collected and sequenced material from their type localities. Pseudohydnum alienum from Europe; P. umbrosum from tempera...

Eighteen specimens of Pluteus collected from the tropical forests of Vietnam were studied using morphological and molecular approaches. Pluteus podospilloides, P. semibulbosus, P. chrysaegis and P. septocystidiatus are registered as additional or new records for Vietnam. Four species (P. conformis, P. lucidus, P. subroseus, and P. ornatus) are prop...

The paper is devoted to ecological and biodiversity studies on basidiomycetes associated with common juniper (Juniperus communis) from subtaiga zone of Belarus as well as several taiga regions of the European part of Russia, namely, the Leningrad Region, the Republic of Karelia, the Komi Republic, the Arkhangelsk Region, the Murmansk Region. The ta...

For Vietnam, a small number of obligate parasitic fungi are given, in powdery mildew (Erisiphales) and rust fungi (Pucciniales). Basically, these are old lists of species that require confirmation or revision. In 2021, a joint expedition was conducted by the staff of the Joint Vietnam-Russia Tropical Science and Technology Research Centre and the K...

The monitoring of trees and shrubs state in the arboretum of the Peter the Great Botanical Garden during 2016‒2020 has revealed the frost cracks in 410 species of trees and shrubs belonging to 34 genera and 20 families of vascular plants. The most common frosts cracks are found in hardwood species such as Acer platanoides (124 exemplars) and Quercu...

The present notice opens a paper series devoted to rare and interesting species of micromycetes causing rust and leaf spots found in various regions of Russia. In June 2019, an interesting species Chrysomyxa succinea, new to the European territory of Russia, was revealed at Peter the Great Botanical Garden of Komarov Botanical Institute (Saint Pete...

The rust fungus Melampsora arctica was described by Rostrup from Greenland in 1888. The uredinium and telium stages of this fungus were confined to polar Salix spp. In 1899, the spermatogonium and aecium stages associated with this species were revealed on Saxifraga spp. During the XX century, M. arctica has been consistently recorded in all region...

Exobasidium representatives cause various deformations of the aerial part of ericaceous, theaceous, and lauraceous plants. In the course of the present research carried out on the territory of the oceanic sector of the European middle taiga subzone in the vicinity of the Vaskelovo settlement (Leningrad Region), we found rather little-known species,...

Ganoderma applanatum is one of the most common polypore in the world. However, due to the variability of its macro- and even micro-characters, it is rather difficult to compile an exact picture of distribution of this fungus both in the world as a whole and in its different regions. At the same time, in cities all the Ganoderma representatives are...
