Abstract:Vertical ectomycorrhizal (ECM) community composition was assessed on silver fir (Abies alba Mill.) in beech-silver fir forests in Bosnia and Herzegovina. Organic and upper mineral horizons were described by pedological analyses. Silver fir root tips were divided into vital ECM, old and non-mycorrhizal for each horizon separately. Morpho-anatomical classification of vital ECM root tips with an assessment of abundance was followed by ITS-based molecular characterization and classification into exploration types. The percentage of vital ECM root tips was not affected by the soil horizon. Altogether, 40 ECM taxa were recorded. Several taxa have not previously been reported for silver fir: Hebeloma laterinum, Inocybe fuscidula, I. glabripes, Lactarius acris, L. albocarneus, L. blennius, L. fluens, Ramaria bataillei, Russula badia, R. lutea, R. mairei, Sistotrema sp., Tarzetta catinus, Tomentella atroarenicolor, T. badia, T. cinerascens, T. bryophylla, and T. ramosissima, indicating high potential for diversity of ECM fungi in silver fir stands. No significant differences in community composition, species richness and diversity were detected between mineral and organic horizons. Community composition was affected by CaCO3, organic carbon, organic carbon stock, total nitrogen stock, C:N ratio and soil density. No significant effects of soil parameters were detected for exploration types. The contact exploration type was dominant in both soil horizons. Significantly different relative abundances of dominant taxa Tomentella stuposa, Cenococcum geophilum and Piloderma sp. 1 were detected in the two horizons. Twelve taxa were limited to the organic horizon and eight to the mineral horizon.
