“…Lineage Inocybe often occur as a pioneer fungi in primary succession sites 28 29 and are also frequently found in disturbed ecological conditions, such as mine wastelands 2 3 30 and post-fire forestland 31 . In the present study, Inocybe was present at all six sites, however, there was a clear decreasing trend in its relative abundance from north (QJ) to south (HL), which is displayed in Fig.…”

“…Ectomycorrhizal symbioses formed between special groups of fungi and plant fine roots, which are essential for plant growth through improving water uptake and nutrient acquisition 1 . In addition, ectomycorrhizal fungi (EMF) can improve their host partner adaptation to diverse stress conditions, such as pathogenesis, heavy-metal toxicity 2 3 , drought conditions 4 , and etc. Approximately 20,000–25,000 EMF species are estimated to exist in nature 5 6 , and ectomycorrhizal plants are often colonized by diverse EMF species, which comprised the important part of forest ecosystem, woodland system and shrub land.…”

The Loess Plateau region of northwestern China has unique geological and dry/semi-dry climate characteristics. However, knowledge about ectomycorrhizal fungal (EMF) communities in the Loess Plateau is limited. In this study, we investigated EMF communities in Populus simonii and Pinus tabuliformis patches within the forest-steppe zone, in pine forests within the forest zone, and the transitional zone between them. We revealed high species richness (115 operational taxonomic units [OTUs]) of indigenous EMF resources at the Loess Plateau, of which Tomentella (35 OTUs), Inocybe (16), Sebacina (16), and Geopora (7) were the most OTU-rich lineages. EMF richness within the forest-steppe zone and the transitional zone was limited, while the natural pine forest maintained diverse EMF communities in the forest zone. The changes of EMF community richness and composition along arid eco-zones were highlighted for the complex factors including precipitation, soil factors, host, DBH, and altitude. Indicator analysis revealed that some EMF showed clear host preference and some taxa, i.e., genera Geopora and Inocybe, were dominant in drought and alkaline-saline conditions attributed to their environmental preference. This study revealed that EMF communities were quite limited in the forest-steppe zone, while the forest region contained diverse EMF communities in the Loess Plateau.

“…Moreover, Rhizopogon spores can survive in soil for many years Nguyen et al 2012), dominating ECM fungal propagule banks in pine forests (Visser 1995;Baar et al 1999;Taylor and Bruns 1999;Kjoller and Bruns 2003;Rusca et al 2006;Glassman et al 2015;Huang et al 2015) and even in forests lacking pine trees (Miyamoto and Nara 2016). Many pine species are successful pioneer colonizers throughout the northern hemisphere due to the ubiquity of Rhizopogon spores in soil (Ashkannejhad and Horton 2006;Huang et al 2014).…”

Interactions between trees and ectomycorrhizal fungi are critical to the growth and survival of both partners. However, ectomycorrhizal symbiosis has barely been explored in endangered trees, and no information is available regarding soil spore banks of ectomycorrhizal fungi from forests of threatened trees. Here, we evaluated soil spore banks of ectomycorrhizal fungi from endangered Japanese Douglas‐fir (Pseudotsuga japonica) forests using bioassay approaches with congeneric P. menziesii and Pinus densiflora seedlings in combination with molecular identification techniques. Rhizopogon togasawariana was predominant in soil propagule banks and was found in all remaining P. japonica forests when assayed with P. menziesii, while no colonization of this fungus was observed on Pinus seedlings. Given the observed specificity of R. togasawariana for P. menziesii and its phylogenetic position within the Pseudotsuga‐specific Rhizopogon lineage, its geographical distribution is likely restricted to the remaining Japanese Douglas‐fir forests, indicating a high extinction risk for this fungus as well as its endangered host. Spore banks of R. togasawariana remained highly infective after preservation for 1 year or heat treatment at 70 °C, suggesting an ecological strategy of establishing ectomycorrhizal associations on regenerating Japanese Douglas‐fir seedlings after disturbance, as observed in other Rhizopogon–Pinaceae combinations. Therefore, the regeneration of Japanese Douglas‐fir seedlings may depend largely on the soil spore banks dominated by R. togasawariana, which has co‐evolved with the Japanese Douglas‐fir for over 30 million years. More attention must be paid to underground ectomycorrhizal fungi for the conservation of endangered tree species, especially in the era of human‐induced mass extinction.

“…Thus, EcM fungi can potentially facilitate revegetation and the development of soils, two key goals in restoration. A number of factors are likely to affect the composition of EcM fungal communities including the presence of particular host species (Ishida et al 2007;Huang et al 2014;Tedersoo et al 2016), variation in soil characteristics (Berg & Smalla 2009;Dickie et al 2009;Ding et al 2011), and time since disturbance (Dickie et al 2013; Barnes et al 2016;Kalucka & Jagodzinski 2016); these factors are also imitated in restoration. Specifically, restoration plans often include decisions on revegetation (i.e.…”

“…lower EcM fungal richness, lower EcM colonization rates, decreased tree seedling survival) (Danielson 1991;Bois et al 2005;Gebhardt et al 2007;Onwuchekwa et al 2014). And yet other studies reported a neutral effect of soils used in the restoration of mine sites on the dominant EcM fungal community (Huang et al 2012(Huang et al , 2014(Huang et al , 2018. As such, it is critical to determine the extent to which species planted, soil placement, and time interact to shape the community structure of EcM fungi.…”

The trajectory of forests establishing on reclaimed oil sands mines in the Canadian boreal forest is uncertain. Soil microbes, namely mycorrhizal fungi, partly underlie successional trajectories of plant communities, yet their role in restoration is often overlooked. Here, we tested the relative importance of common management tools used in restoration—species planted and soil placement—on the recovery of ectomycorrhizal fungal communities over 4 years. Importantly, we further compared the community assembly of fungi on reclaimed landscapes to that in reference ecosystems disturbed to different degrees. This latter test addresses whether disturbance intensity is more important than common management interventions to restore fungal communities in these ecosystems. Three main findings emerged. (1) The effect of tree species planted and soil placement on ectomycorrhizal fungal communities establishing on reclaimed landscapes was dynamic through time. (2) Disturbances that remove or disrupt the organic layer of soils substantially affect the composition of ectomycorrhizal fungal communities. (3) Shifts in the community composition of ectomycorrhizal fungi were driven to a greater extent by disturbance severity than either tree species planted or soil placement.
