“…Piętka et al (2019) described a total of 32 taxa, with 25 being in the reserve stand and 12 in the managed stand. Kwaśna et al (2017) recorded wood samples of Scots pine basidiomata of four taxa (Armillaria ostoyae, Heterobasidion annosum, Hebeloma fasciculare, and Trichaptum fuscoviolaceum), which were also identified in the present study. Sierota et al (2016) found Phlebia tremellosa (identified here) on Norway spruce stumps; however, Phlebiopsis gigantea, a common fungus on coniferous stumps and in roots in Poland (Sierota, 1995), was not recorded on stumps of three assessed trees.…”

In fall 2018 and 2019, we assessed colonization by fungi on Douglas fir trees [Pseudotsuga menziesii (Mirb.) Franco], white pine (Pinus strobus L.), and red cedar (Thuja plicata D. Don.) on selected experimental plots of the former Prussian Experimental Station, where nonnative tree species were introduced from North America over a century ago. The presence of sporocarps on trunks, root collars, and stumps as well as the litter layer in the soil within a radius of 0.5 m around the trunk of the tree was determined. Additionally, the volume of dead wood on the forest floor of the entire plot was assessed. We recorded numerous fungi on trees and stumps as well as in the litter and soil. For the 31 plots in 12 forest districts, we determined 745 sporocarps of 48 taxa, with 335/19 on the wood of P. menziesii trees and stumps, 377/15 on P. strobus, and 33/6 on T. plicata trees. The highest share of trees with various trunk damage levels was found for T. plicata (70.3%) and the lowest for P. menziesii (6.2%). Among the root parasitic fungi, Heterobasidion sp. and Armillaria sp. were found, especially on the collars and stumps of T. plicata and P. strobus; we did not find basidiomata of both pathogens on P. menziesii. The volume of dead wood within the P. menziesii plots averaged 7.1 m3/ha, whereas in T. plicata plots, it was 56.3 m3/ha. We identified 10 taxa that have not been reported in association with P. strobus for Poland (Cylindrobasidium laeve, Dacrymyces sp., Exidia pithya, E. saccharina, Gymnopilus pnetrans, Leptoporus mollis, Mycena sanguinolenta, Tapinella panuoides, Trametes versicolor, and Xylaria hypoxylon) and three taxa (Exidia pithya, Leptoporus mollis, Serpula himantioides) associated with T. plicata.

“…Oomycetes dwelling the ground habitats are thus capable of feeding on the dead organic matter in the soil, leaf litter and deadwood samples. Deadwood on the forest floor has already been shown to harbour hemibiotrophic oomycetes (Kwaśna et al 2017a;2017b). In the canopy, however, deadwood harbours only little hemibiotrophic species, as they are dominated by obligate biotrophic species, like the other canopy habitats.…”

Oomycetes (Stramenopiles, Protista) are among the most severe plant pathogens, comprising species with a high economic and ecologic impact on forest ecosystems. Their diversity and community structures are well studied in terrestrial habitats, but tree canopies as huge and diverse habitats have been widely neglected. A recent study highlighted distinct oomycete communities in the canopy region compared to forest soils when taking oomycete abundances into account, in contrast to the homogeneity at the incidence level. It remains however unknown if this homogeneity also leads to a functional homogenisation among microhabitats. In this study, we supplemented functional traits to oomycete canopy and ground communities, which were determined over a time period of two years with a metabarcoding approach. Our results showed that even though most oomycetes occurred in all habitats, a strong discrepancy between the strata and correspondingly the distribution of oomycete lifestyles could be observed, which was constant over time. Obligate biotrophic species, exclusively feeding on living host tissue, dominated the canopy region, implying tree canopies to be a hitherto neglected reservoir for parasitic protists. Parasites highly specialised on hosts that were not sampled could be determined in high abundances in the canopy and the surrounding air, challenging the strict host dependencies ruled for some oomycetes. Our findings further contribute to the understanding of oomycete ecosystem functioning in forest ecosystems.

“…Temperature and precipitation are the two major determinants of macrofungi ( Zhai and Pan, 2003 ; Piao et al, 2006 ). Macrofungi are also affected by the chemical properties of soil ( Rühling and Tyler, 1990 ; O’Hanlon and Harrington, 2012 ), the chemical properties and structural characters of rotten wood ( Blaser et al, 2013 ; Kwaśna et al, 2017 ), and the age of forest ( Stokland et al, 1997 ; Nordén and Paltto, 2001 ). The consideration of more environmental factors will be more meaningful, because some factors may together significantly contribute to macrofungi community variance.…”

“…Spatial studies on macrofungi have mainly focused on describing species diversity in different types of forests ( Nordén and Paltto, 2001 ) and determining their relationship to plant community ( Ferrer and Gilbert, 2003 ) and topography ( Alday et al, 2017 ). Furthermore, the relationships between wood-decay and rotten-wood fungi have been widely investigated ( Nordén and Paltto, 2001 ; Blaser et al, 2013 ; Kwaśna et al, 2017 ). Although these studies may contribute to our understanding of macrofungi community assembly, the major drivers of macrofungi community remain unclear.…”

“…Rotten wood is an important habitat that can sustain the growth of macrofungi ( Blaser et al, 2013 ). Therefore, many more studies on rotten-wood macrofungi are available compared to those of macrofungi that grow on other substrates ( Nordén and Paltto, 2001 ; Blaser et al, 2013 ; Kwaśna et al, 2017 ). However, the characteristics of growth and distribution may differ among fungi growing on different substrates ( Senn-Irlet et al, 2007 ), and the drivers of community structure in rotten wood relative to soil macrofungi have not been well elucidated yet.…”

Drivers of Macrofungi Community Structure Differ between Soil and Rotten-Wood Substrates in a Temperate Mountain Forest in China

The effects of environmental and dispersal processes on macrofungi community assembly remain unclear. Further, it is not well understood if community assembly differs for different functional guilds of macrofungi, e.g., soil and rotten-wood macrofungi. In this study, using 2433 macrofungi sporocarps belonging to 217 species located within a forest dynamics plot in temperate mountain forest (China), we examined the explanatory power of topography, spatial eigenvectors (representing unknown spatial processes, e.g., dispersal), plant community, and light availability for local spatial variation in the macrofungi community through variance partitioning and partial least squares path modeling. We found spatial eigenvectors and light as the most important factors for explaining species richness and composition of macrofungi. Light was negatively correlated with species richness of macrofungi. Furthermore, species richness and composition of soil macrofungi were best explained by light, and species richness and composition of rotten-wood macrofungi were best explained by spatial eigenvectors. Woody plant community structure was not an important factor for species richness and composition of macrofungi. Our findings suggest that spatial processes, perhaps dispersal limitation, and light availability were the most important factors affecting macrofungi community in temperate deciduous broad-leaved forest. Major differences in influencing factors between soil and rotten-wood macrofungi were observed, with light as the major driver for soil macrofungi and unknown spatial processes as the major driver for rotten-wood macrofungi. These findings shed new light to the processes shaping community assembly in macrofungi in temperate deciduous broad-leaved forest and point to the potential importance of both intrinsic dynamics, such as dispersal, and external forcing, such as forest dynamics, via its effect on light availability.
