The present study reports the discovery of three bryophilous and six lichenicolous species of nectrioid Sordariomycetes in Hungary. The bryophilous species Bryocentria brongniartii was found to be growing on Frullania dilatata, B. metzgeriae on Radula complanata and Metzgeria furcata, while Nectria muscivora on Barbula unguiculata and Didymodon cor...

The relevance of forests in mitigating biodiversity loss and the negative effects of climate change on the biota is largely shaped by below-canopy microclimatic conditions, which are buffered, cooler and more humid compared to adjoining open habitats. Water-filled tree holes (dendrotelms, DTs) are special tree-related microhabitats that host semi-a...

Hornbeam (Carpinus betulus) is an economically significant tree species, serving as a valuable resource for timber and ornamental wood products. It plays a crucial ecological role within forest communities and exhibits wide distribution across Central Europe. During October 2022 and March 2023, we encountered instances of declining hornbeam trees i...

Aim Dead wood inhabiting bryophyte communities are formed by several important factors. Besides the amount, quality and continuity of the substrate, there are also external factors indirectly influencing their structure. One of the most important is local microclimate. This fact has been recognized by many previous authors, yet studies exploring th...

There is a paradigm shift in silviculture towards the not just economically but also ecologically sustainable continuous cover forestry (CCF) methods. Their aims are to provide timber, to maintain buffered microclimate and biodiversity, and to meet social requirements simultaneously. However, the concept and the details of these techniques has to d...
