Resumen
Pinus trees are able to form associations with fungal species that have both ecological and economic benefits. The present study examined the macrofungal succession and correspondingsporocarp production in Pinus patula stands in Ethiopia. Fungal taxa composition was also explained based on edaphic variables of the study area. For this purpose, we surveyed nine permanent plots (100 m2) established in five-, eleven-, and thirty-six years old P. patulaplantations and estimated fungal taxa richness, diversity, and sporocarp yields. Composite soil samples were also collected from each plot to determine explanatory edaphic variables for fungaltaxa compositions. We found a total of 53 fungal taxa belonging to Basidiomycota, with the exception of Xylaria hypoxylon which is Ascomycota. The majority of the collected taxa were saprophytic and only 6% were ectomycorrhizal fungi (ECM). About 36% of the taxa were classified as edible. Taxa richness, the Shannon diversity, and sporocarp yields showed significant increasing trends towards the more mature P. patula stands. Fungal community composition was also correlated significantly with N, K, and pH. This study extends our knowledge on fungal diversity and community structure in managed P. patula plantations. Higher diversity and sporocarp production was found in older stands. Thus, the deliberate presence of mature trees in Pinus stands could provide incentives for the production and conservation of important fungal species in the study area.
