“…In FW soils, P. chilensis roots were colonized by about double the number of unique ASVs as P. tamarugo ( Figure S3b ), although most of these were annotated as unknown, with a few, such as Cortinarius , S. terrea and Fusarium , successfully annotated ( Table S7 ). Unique fungal ASVs recruited by Prosopis tamarugo were dominated by Debaryomycetaceae spp., which corresponds to a yeast family often found within insect guts [ 70 ] and a decomposer from the Onygenales order [ 71 ] ( Table S7 ). Finally, a similar number of unique fungal ASVs were found in FO soils ( Figure S3b ), with P. chilensis being colonized by members of the Fusarium genera, as well as the arbuscular mycorrhiza Diversispora epigaea [ 72 ], and the beneficial soil yeast S. terrea ( Figure 5 c, Table S7 ).…”

Prosopis chilensis and Prosopis tamarugo, two woody legumes adapted to the arid regions of Chile, have a declining distribution due to the lack of new seedling establishment. This study investigated the potential of both species to establish in soil collected from four locations in Chile, within and outside the species distribution, and to assess the role of the root-colonizing microbiome in seedling establishment and growth. Seedling survival, height, and water potential were measured to assess establishment success and growth. 16S and ITS2 amplicon sequencing was used to characterize the composition of microbial communities from the different soils and to assess the ability of both Prosopis species to recruit bacteria and fungi from the different soils. Both species were established on three of the four soils. P. tamarugo seedlings showed significantly higher survival in foreign soils and maintained significantly higher water potential in Mediterranean soils. Amplicon sequencing showed that the four soils harbored distinct microbial communities. Root-associated microbial composition indicated that P. chilensis preferentially recruited mycorrhizal fungal partners while P. tamarugo recruited abundant bacteria with known salt-protective functions. Our results suggest that a combination of edaphic properties and microbial soil legacy are potential factors mediating the Prosopis establishment success in different soils.

“…These findings and others previously reported [27][28][29][30][32][33][34][35][36]38,76] suggest that fluvial sediments are a good source of onygenalean fungi, and further investigation on their diversity is required. On that point, special attention should be paid to fluvial sediments in humid regions in the Northern Hemisphere, particularly sites in Eastern Europe, which have recently been defined as important hotspots of Onygenales [90].…”

During the course of a project investigating culturable Ascomycota diversity from freshwater sediments in Spain, we isolated 63 strains of cycloheximide-resistant fungi belonging to the order Onygenales. These well-known ascomycetes, able to infect both humans and animals, are commonly found in terrestrial habitats, colonizing keratin-rich soils or dung. Little is known about their diversity in aquatic environments. Combining morphological features and sequence analyses of the ITS and LSU regions of the nrDNA, we identified 14 species distributed in the genera Aphanoascus, Arachniotus, Arthroderma, Arthropsis, Emmonsiellopsis, Gymnoascoideus, Leucothecium, Malbranchea, and Myriodontium. Furthermore, three novel species for the genus Malbranchea are proposed as M. echinulata sp. nov., M. irregularis sp. nov., and M. sinuata sp. nov. The new genera Albidomyces and Neoarthropsis are introduced based on Arachniotus albicans and Arthropsis hispanica, respectively. Neoarthropsis sexualis sp. nov. is characterized and differentiated morphologically from its counterpart by the production of a sexual morph. The novel family Neoarthropsidaceae is proposed for the genera Albidomyes, Apinisia, Arachnotheca, Myriodontium, and Neoarthropsis, based on their phylogenetic relationships and phenotypic and ecological traits. Pseudoamaurascopsis gen. nov. is introduced to accommodate P. spiralis sp. nov., a fungus with unclear taxonomy related to Amaurascopsis and Polytolypa. We traced the ecology and global distribution of the novel fungi through ITS environmental sequences deposited in the GlobalFungi database. Studying the fungal diversity from freshwater sediments not only contributes to filling gaps in the relationships and taxonomy of the Ascomycota but also gives us insights into the fungal community that might represent a putative risk to the health of animals and humans inhabiting or transient in aquatic environments.

“…Humidity and temperature, in general, are also the most critical factors affecting the presence of fungal particles. Coleine et al (2022) state that humidity, wet, and acid soils are essential for fungal sprouting. Daily air temperature and humidity fluctuations for the six months of testing are shown in Figure 11 for the residential site and Figure 12 for the arboretum.…”

Abstract. Nurhadi MW, Arinana A, Rahmawati AI, Herliyana EN, Andika R, Himmi SK. 2023. Wood decomposers on six community timber species in two different locations. Biodiversitas 24: 6629-6640. Wood has a close relationship with termites and fungi as decomposers. Decomposers are important as dead organic matter is broken down into elements and returned to the soil. This study aims to analyze the amount of wood attacked by termites and fungi on six types of community timber during six months of testing at two different locations, analyze the degree of damage, and identify the species of termites and fungi that attack them. The research was conducted in two locations: the Arboretum of the Faculty of Forestry and Environment of IPB and a residential area in Bogor Asri, Cibinong Sub-district, Bogor District. The wood tested were Acacia mangium, Falcataria moluccana, Anthocephalus cadamba, Maesopsis eminii, Pinus merkusii, and Hevea brasiliensis. Tests were conducted based on ASTM D 1758-06. Infested wood increased with the time tested, and infestation was higher in the arboretum (75%) than in the residential area (39.4%). The highest level of wood damage in the arboretum was Hevea brasiliensis (35.4 g); in residential, it was Pinus merkusii (18.9 g). The subterranean termite types found during the six months of testing are Macrotermes sp., Microtermes sp., Schedorhinotermes sp., and Odontotermes sp. The weathering fungi types found during the six months of testing were Aspergillus sp., Mucor sp., Trichoderma sp., Gliocladium sp., Mycelia sterilia, and red fungus. Soil type, moisture, and ambient temperature also strongly favored the development of decomposer life found in the two research sites.
