With the simultaneous growth in interest from the mycological community to discover fungal species and classify them, there is also an important need to assemble all taxonomic information onto common platforms. Fungal classification is facing a rapidly evolving landscape and organizing genera into an appropriate taxonomic hierarchy is central to be...

The widely treated order Capnodiales is one of the most important orders in the class Dothideomycetes. Recently, the order Capnodiales s. lat. was reassessed and split into seven orders (Capnodiales s. str., Cladosporiales, Comminutisporales, Mycosphaerellales, Neophaeothecales, Phaeothecales and Racodiales) based on multi-locus phylogeny, morpholo...

Novel species of fungi described in this study include those from various countries as follows: Australia, Baobabopsis sabindy in leaves of Eragrostis spartinoides, Cortinarius magentiguttatus among deep leaf litter, Laurobasidium azarandamiae from uredinium of Puccinia alyxiae on Alyxia buxifolia, Marasmius pseudoelegans on well-rotted twigs and l...

Novel species of fungi described in this study include those from various countries as follows: Argentina, Neocamarosporium halophilum in leaf spots of Atriplex undulata. Australia, Aschersonia merianiae on scale insect (Coccoidea), Curvularia huamulaniae isolated from air, Hevansia mainiae on dead spider, Ophiocordyceps poecilometigena on Poecilom...

Lophium arboricola is known as a saprotrophic fungus from different substrates, but it was mainly reported from conifers. In this study, two strains of fungi found growing on resin were molecularly identified as Lophium arboricola. The species was isolated from the resin of Picea abies and Abies alba in Poland. It is the first report of L. arborico...

Coniochaeta fodinicola is an acidophilic fungus which has been isolated only several times from extremely acidic environments. In this study, Coniochaeta fodinicola was isolated from a sulphurous spring with slightly acidic, nearly neutral pH water (pH = 6.8) in Poland. The identification of this fungus was conducted based on sequencing and phyloge...

The fungal genus Rachicladosporium (Cladosporiales, Cladosporiaceae), typified by cladosporium-like Rachicladosporium luculiae, includes a morphologically diverse assemblage of species. The species of this genus were reported from different substrates, habitats and environments, including plant leaves and needles, twig, black mould on baobab trees,...

The boxelder maple (Acer negundo, Sapindaceae) is one of the most common tree species of the genus Acer natively growing in North America. In the 17th century, A. negundo was introduced to Europe as an ornamental plant, and from this time, it started an uncontrolled expansion into new territories, threatening local ecosystems. Fungal development on...

Novel species of fungi described in this study include those from various countries as follows: Australia, Aschersonia mackerrasiae on whitefly, Cladosporium corticola on bark of Melaleuca quinquenervia, Penicillium nudgee from soil under Melaleuca quinquenervia, Pseudocercospora blackwoodiae on leaf spot of Persoonia falcata, and Pseudocercospora...

The anthropogenic pressure on the environment depends on the spatial scale. It is crucial to prioritise conservation actions at different spatial scales to be cost-efficient. Using horizon scanning with the Delphi technique, we asked what the most important conservation problems are in Poland at local and national scales. Twenty-six participants, P...

A clade where the most halotolerant fungus in the world – Hortaea werneckii, belongs (hereafter referred to as Hortaea werneckii lineage) includes five species: Hortaea werneckii, H. thailandica, Stenella araguata, Eupenidiella venezuelensis, and Magnuscella marina, of which the first species attracts increasing attention of mycologists. The specie...

Pseudodidymella fagi, described from infected leaves of Fagus crenata in Japan, has recently been spreading in Europe, where it causes leaf blotch of European beech Fagus sylvatica. In the years 2008–2016, an outbreak of P. fagi was observed on European beech in Switzerland, Germany and Austria, and it is reported here for the first time from Slova...

In order to recognize interactions between alien vascular plants and soil microorganisms and thus better understand the mechanisms of plant invasions, we examined the mycorrhizal status, arbuscular mycorrhizal fungi (AMF) colonization rate, arbuscular mycorrhiza (AM) morphology and presence of fungal root endophytes in 37 non-native species in Cent...
