“…A. Goychuk et al (2022) described that the overall sanitary condition of dark coniferous forests forms a close correlation between biotic predictors and abiotic factors. Currently, the phytopathogenic bacterium Lell iottia nimipressuralis (Carter 1945) (Brady et al, 2013) is a major contributor to the general pathology of white fir, characterised by its dynamic spread within the range of forests with white fir and causing massive mortality of trees of different age groups.…”

The current state of dark coniferous forests on Earth is a bio-indicator of global environmental change, in particular, the process of gradual degradation of tree species of the genera Pine, Spruce and Fir, due to the negative impact of anthropogenic activities, abiotic and biotic factors. The purpose of the study is to establish the symptoms, prevalence and harmfulness of the causative agent of ulcerative tumour-like disease on the shoots and trunks of white fir. The research was conducted on the territory of the forest fund of the Pokuttia Carpathians, in particular, within the branch Kutske forestry of the State Specialised Economic Enterprise “Forests of Ukraine” in the Kosivske forest enterprise. The study uses classical phytopathological and mycological methods, which are used to investigate the aetiology of the disease, analyse typical symptoms (starting from the early stages), and perform microscopy of the affected parts of fir. The symptoms, aetiology, and pathogenesis of white fir ulcer-like disease, which tends to spread, were investigated. A new name for the disease is substantiated, in particular, it is proposed to use the name “ulcerative tumour-like disease” of fir instead of the current name “cancer”. It is shown that a typical sign of infection is the development of tumours, which eventually transform into ulcers. It was found that the tumour-like type of lesion prevails on the undergrowth of fir, and on plants of the upper tiers – ulcerative. It is noted that a typical sign of ulcerative tumour-like disease of white fir is also the presence of pathologies such as “witches’ broom”. It is proposed to remove affected trees with typical signs of infection with ulcerative tumour-like disease to reduce the infectious background, especially during lighting and cleaning, since affected trees are not released from infection. Therefore, assessing the risk of infection of white fir trees with ulcerative tumour-like disease at the level of specific stands and ensuring an appropriate response to potential infection risks is an important part of sustainable forest management

Aphyllophoroid macromycetes are a key link in natural and artificial biocenoses, in particular, forest ecosystems. Their peculiarity is due to the variety of morphological forms and the ability to colonise various substrates. The establishment of fundamental issues of the biotic organisation of this group of fungi, which considers both their specific features and integration into general ecological patterns, forms the necessary basis for their further research, protection, and practical use (in particular, when indicating and monitoring the state of forest biocenoses). The purpose of the study was to establish the species composition, taxonomic structure, and distribution (by mycohorizons) of aphyllophoroid macromycetes of forest stands in Zhytomyr Polissia. In the course of the study, classical phytopathological and forestry-inventory (biometric) analysis methods were used. Special methods of mycology, in particular, mycoindication, were also used in terms of identifying and examining aphyllophoroid macromycetes. Mycoflora of aphyllophoroid macromycetes of forest stands of Zhytomyr Polissia has 27 species belonging to 17 families, 8 orders of the Agaricomycetes class of the Basidiomycota division and is typical for the European temperate zone. The systematic component of the group under study is represented by the following orders: Polyporales (40.7% of their total number), Hymenochaetales (18.5%), Agaricales (14.8%), Russulales (11.2%), Cantharellales, Thelephorales, Auriculariales, and Gomphales (3.7% each). Analysis of the food structure of aphyllophoroid macromycetes shows that most of the mycoflora is represented by a complex of saproxilotrophic species, to a lesser extent parasite fungus (for example, Inonotus hispidus, Phellinus robustus, Heterobasidion annosum) and humus saprotrophs (Thelephora terrestris) are noted. The distribution of macromycetes by mycohorizons identifies that more than 70% of all finds were located in the subsurface mycohorizon, and the root mycohorizon is characterised by the smallest number of finds and species of macromycetes. There is a gradual decrease in the species diversity of aphyllophoroid macromycetes in the forest edge areas, which demonstrates fundamentally different stages of forest ecosystem degradation processes. The investigation of historical relationships between woody plant species and aphyllophoroid macromycetes, which act as biological indicators of the state of forest ecosystems, will further allow forming the of “maps of disruption of the integrity of forest biocenoses” for the analysis of sanitary risks, which should be implemented in the practice of forest protection
