“…The old-growth beech forests, rich in arboreal species, showed greater evenness but low abundance of macrofungi. In most unmanaged beech forest plots, besides highly productive and frequent species such as the lignicolous Bisporella citrina, Trametes hirsuta, Micromphale foetidum, Schizophyllum commune, the more rare ectomycorrhizal fungi with low abundance such as Cortinarius alboviolaceus, C. terpsichores, Inocybe asterospora, I. furfurea, Lactarius flavidus, Russula fellea and Thelephora palmata can be found in greater proportion, presumably because of the host trees and forest structure (Bujakiewicz 1992;Pál-Fám et al 2007) as well as the physical and chemical properties of the humus (Nantel and Neumann 1992). The abandoned oak wood-pasture is the richest in vascular plants, but fungal abundance is low there.…”

The diversity of easy-to-study organisms (e.g. vascular plants) is often used as a proxy for the diversity of other organisms whose investigation needs more effort, time and specialist knowledge. Some previous studies have found positive relationships between plant and macrofungal diversity and thus support this approach, while others question this practice. Our aim was to explore the possibility of using plant diversity as surrogate for macrofungal diversity in the forests of the Pannonian ecoregion. A total of 19 permanent plots in north-east Hungary were sampled for vascular plants and macrofungi. The effect on macrofungal abundance and diversity, of plant evenness and richness as well as degradation level was tested using generalized linear models. Species richness of macrofungi assemblages proved to be independent of the diversity and naturalness of vascular plant communities; however, there was congruence in the composition of the two communities. In contrast to diversity, macrofungi abundance was significantly negatively correlated to plant species richness. There was a hump-backed relationship between the abundance of terricolous macrofungi and the degradation level estimated on the basis of the occurrence of vascular plants, although degradation did not influence the abundance of lignicolous macrofungi. Our results question the reliability of decisions on nature conservation actions based on a few groups of easy-to-observe organisms, and underline the necessity of studying as wide a range of taxonomic groups as possible.

“…For this reason, it is considered as a distinct ecological region (Pannonian ecoregion) in the Natura 2000 programme. Only some preliminary investigations of macrofungi-plant interactions have been published for the Pannonian ecoregion (Benedek et al 2005;Pál-Fám et al 2007). …”

“…On the basis of the results it can be established that the diversity and structure of the terricolous macrofungi assemblages are mainly affected by climatic and habitat conditions [20] and the degradation of the plant associations to a lesser degree. The terricolous macrofungi (ectomycorrhizal and saprotrophs) community of the semi-natural beech forest, in which forestry management hasn't been practiced, shows the highest diversity.…”

“…Some surveys have been dealt with composition and diversity of macrofungi assemblages in different vegetation types using different diversity indices and statistic methods [13][14][15][16][17][18][19][20] The communities which are rich in species can be characterized log-normal or "broken stick" distribution [21]. Rank-abundance curves for comparison of macrofungi assemblages have been used only in a few cases [20,22], whereas it is a wellknown method of the disturbance research for other taxa (i.e. vascular plants [23]).…”

Macrofungi play an extraordinarily important role in the catalysis of the nutrient cycle of deciduous and coniferous forests. Habitat degradation adversely influences the number of fruiting bodies of macrofungi and diminishes the diversity of the fungal community. The diversity of the terricolous- and lignicolous macrofungi assemblages were compared in stands of semi-natural and two plant associations modified by humans in different degrees in North-East Hungary. We used data from 15 permanent plots that were sampled for vascular plants and macrofungi. Rank-abundance curves and Rényi’s diversity profiles were applied for diversity research. The results indicated that structure and diversity of the terricolous macrofungi assemblages were mainly influenced by climatic and habitat conditions and the degradation of the plant associations to a lesser degree. The diversity of lignicolous macrofungi was primarily affected by the continuous presence, quality, and quantity of deadwood. Accordingly, the form and degree of forest management, as well as the age of the growing stocks, influenced community structure. If nature conservation planning and conservation activity are based on those biodiversity indicators which are good proxies for macrofungi biodiversity, the latter might be optimal for preserving macrofungi biodiversity.

“…and whitebeam (Sorbus spp.). With respect to basidiomycetes, to which the majority of ECM fungi belong, the current knowledge with regard to taxonomic diversity and distribution in Northern Hungary is based on sporocarp studies (Bohus and Babos, 1960;Takács and Siller, 1980;Rimóczi, 1992Rimóczi, , 1994Tóth, 1999;Siller et al, 2002aSiller et al, ,b, 2006Albert and Dima, 2005;Egri, 2007;Pál-Fám et al, 2007;Rudolf et al, 2008;Siller, 2010;Siller and Dima, 2014). In addition, several taxa in the ECM genera Humaria, Genea, Tomentella, and Tuber were characterized morphologically and molecularly in beech root tip studies carried out in a protected montane beech forest reserve in the Bükk Mountains (Kovács and Jakucs, 2006;Erős-Honti et al, 2008;Jakucs et al, 2015).…”

Abiotic environmental factors drive the diversity, compositional dynamics and habitat preference of ectomycorrhizal fungi in Pannonian forest types

Ectomycorrhizal (ECM) fungi are among the most diverse and dominant fungal groups in temperate forests and are crucial for ecosystem functioning of forests and their resilience toward disturbance. We carried out DNA metabarcoding of ECM fungi from soil samples taken at 62 sites in the Bükk Mountains in northern Hungary. The selected sampling sites represent the characteristic Pannonian forest types distributed along elevation (i.e., temperature), pH and slope aspect gradients. We compared richness and community composition of ECM fungi among forest types and explored relationships among environmental variables and ECM fungal alpha and beta diversity. The DNA sequence data generated in this study indicated strong correlations between fungal community composition and environmental variables, particularly with pH and soil moisture, with many ECM fungi showing preference for specific zonal, topographic or edaphic forest types. Several ECM fungal genera showed significant differences in richness among forest types and exhibited strong compositional differences mostly driven by differences in environmental factors. Despite the relatively high proportions of compositional variance explained by the tested environmental variables, a large proportion of the compositional variance remained unexplained, indicating that both niche (environmental filtering) and neutral (stochastic) processes shape ECM fungal community composition at landscape level. Our work provides unprecedented insights into the diversity, landscape-level distribution, and habitat preferences of ECM fungi in the Pannonian forests of Northern Hungary.
