“…Due to the high frequency of symbiotic interaction in the restinga, ECM have a potentially critical role in restoration and management interventions in these ecosystems. 26 ECM can improve host plant resistance to pathogens through direct competition; 27 they can increase plant drought tolerance by improving plant-soil contact surface, host plant water conductivity, and resistance to high soil salinity by restricting sodium uptake by plant tissues and activating stress response pathways. 28 Sadly, anthropic activities are negatively affecting the diversity and functionality of the ectomycorrhizal community in forest soils due to soil erosion, changes in land use, inorganic toxins, fire, and non-native plant invasions.…”

Background: The Brazilian Atlantic Forest is one of the most biodiverse terrestrial ecoregions of the world. Among its constituents, restinga vegetation makes a particular case, acting as a buffer zone between the oceans and the forest. Covering some 80% of Brazilian coastline (over 7,300 km in length), restinga is a harsh environment where plants and fungi interact in complex ways that just now are beginning to be unveiled. Ectomycorrhizal symbiosis, in particular, plays a so far ungauged and likely underestimated role. We recently described the morpho-anatomical and molecular features of the ectomycorrhizae formed by several basidiomycetous mycobionts on the host plant Guapira opposita, but the mycorrhizal biology of restinga is still largely unexplored. Here, we report new data on the ectomycorrhizal fungal symbionts of G. opposita, based on the collection of sporomata and ectomycorrhizal root tips in restinga stands occurring in southern Brazil. Methods: To obtain a broader view of restinga mycorrhizal and ecological potential, we compiled a comprehensive and up-to-date checklist of fungal species reported or supposed to establish ectomycorrhizae on restinga-inhabiting host plants, mainly on the basis of field observations. Results: Our list comprises some 726 records, 74 of which correspond to putative ectomycorrhizal taxa specifically associated with restinga. These include several members of Boletaceae, Amanita, Tomentella/Thelephora, Russula/Lactifluus, and Clavulina, as well as hypogeous fungi, like the recently described Longistriata flava. Conclusions: Our survey reveals a significant diversity of the restinga ectomycorrhizal mycobiota, indicating the importance of this symbiosis for the ecological functioning of a unique yet poorly known and threatened ecosystem.

“…ECM presents an alternative to strengthen the sustainability of plantation forests and reduce dependence on chemical fertilizers from non-renewable sources (Wu et al 2023). Generally, ectomycorrhizal fungi are used as biological fertilizers for food crops, plantations, forestry and even rehabilitation of degraded lands (Kałucka and Jagodziński 2016;Weidlich et al 2020;Sánchez-Ledesma et al 2022). The ectomycorrhizal fungi include three divisions namely: Ascomycota, Basidiomycota and Zygomycota, there are >250 genera and an estimated 20,000 species (Janowski and Leski 2023).…”

Abstract. Sufaati S, Suharno, Agustini V, Suwannasai N. 2023. New records of the diversity of Scleroderma spp. from Papua, Indonesia. Biodiversitas 24: 4269-4276. Papuan forest is one of the highest diversity tropical rainforests in the world. However, in some areas it is undergoing in process of land degradation. Reforestation using local plant inoculated with native mycorrhiza may have better results since they will be more adaptable. Mycorrhiza helps in plant nutrient uptake and ameliorates heavy metals in mining areas. Genus Scleroderma is a group of ectomycorrhiza that can be found at early stage of succession. However, to date there has been little study on its taxonomy. This study was conducted to construct the database on the diversity of Scleroderma spp. in Papua, Indonesia. Samples were collected from several areas in the provinces of Papua and West Papua from 2003 to 2022. Morphological characters and its habitat were observed. The results show, that 23 isolates had been documented. Molecular identification using ITS sequences was used to confirm the Scleroderma to the species level. The results found at least 3 species of Scleroderma, namely: Scleroderma suthepense, S. xanthochroum, and S. sinnamariense were identified based on morphological and molecular analysis, while S. citrinum was identified morphologically. This finding provides new data on the distribution of Sclerodermataceae in Papua. The results of this preliminary study are important for selecting native Scleroderma spp. for inoculation programs in degraded land.
