Ectomycorrhizae of Norway spruce from its southernmost natural distribution range in Serbia
Hojka Kraigher, Milan Drekić, Saša Pekeč, Tine Grebenc, Marko Bajc, Saša Orlović, Marina Katanić

Povzetek: Norway spruce (Picea abies Karst.) reaches its southernmost limit in the mountainous regions of south Serbia and Bulgaria. The species is a regionally important timber species for the wood industry and a significant host for various ectomycorrhizal fungi, including edible species. We analysed ectomycorrhizal community and fine root parameters of high continental / subalpine Norway spruce stands at three sites (Stara planina, Kopaonik, Tara) located in protected areas in Serbia. In addition, we assessed the potential effects of altitude and growing season on the ectomycorrhizal diversity and fine root parameters. Using standardised sampling in combination with morpho-anatomical and molecular identification of ectomycorrhizae, we recorded 29 different anatomorphotypes. None of the identified fungi belonged to commercial edible fungal species. Compared to other Norway spruce ectomycorrhiza studies in central Europe, sites in Serbia exhibited lower species diversity and different dominant species composition, with Cenococcum spp. and Russula spp. as the dominant ectomycorrhizal fungi. A number of ectomycorrhizal types and the value of the species richness index differed between Stara planina and Tara in the autumn, but the influence of site and season on the studied diversity indices was not significant. The total number of fine roots increased in the spring, while percentage of vital ectomycorrhizal root tips increased in the autumn. This study was the first examination of Norway spruce ectomycorrhizal communities at the edge of the natural geographical range of the species.

Ectomycorrhizal fungi from southern Brazil - a literature-based review, their origin and potential hosts
Marcelo Aloisio Sulzbacher, Tine Grebenc, RJS Jacques, Zaida Ines Antoniolli, 2013

Povzetek: A first list of ectomycorrhizal and putative ectomycorrhizal fungi from southern Brazil (the states of Rio Grande do Sul, Santa Catarina and Paraná), their potential hosts and origin is presented. The list is based on literature and authors observations. Ectomycorrhizal status and putative origin of listed species was assessed based on worldwide published data and, for some genera, deduced from taxonomic position of otherwise locally distributed species. A total of 144 species (including 18 doubtfull species) in 49 genera were recorded for this region, all accompanied with a brief distribution, habitat and substrate data. At least 30 collections were published only to the genus level and require further taxonomic review.

Brown rotting fungus closely related to Pseudomerulius curtisii (Boletales) recorded for the first time in South America
DB Baldoni, G Coelho, RJS Jacques, RMB Silveira, Tine Grebenc, Zaida Ines Antoniolli, 2012

Povzetek: In the region of Santa Maria, Southern Brazil, we have analyzed morphologically and molecularly some interesting brown-rotting mushroom specimens closely related to Pseudomerulius curtisii. Except for minor differences in morphology and ITS sequence similarity, collections have corresponded to P. curtisii by basidiospore size and shape, the kind of hyphal system, the macromorphology, the slightly unpleasant pungent spicy smell turning stronger upon drying and, particularly, by the highly supported and closely related clade after phylogenetic analysis. Perhaps due the rarity in nature, morphological data are not abundant in literature and appears to be somewhat incomplete to discordant for the species, so we provide a more detailed description and illustrations from collected specimens.
