1. Truffle mycorrhization in a pecan orchardMylla Trisha Mello Souza, Joice Aline Freiberg, Tine Grebenc, Marcelo Aloisio Sulzbacher, Diniz Fronza, Juliano Borela Magalhães, Vanessa da Rosa Gonçalves, Nathalie Caroline Hirt Kessler, Lucas Moura Somavilla, Zaida Ines Antoniolli, 2024, izvirni znanstveni članek Povzetek: The ectomycorrhizal association of Tuber spp. in orchards is essential for truffle production. In this sense, this study aimed to evaluate the ectomycorrhizal association of Tuber aestivum Vittad. and Tuber brumale Vittad. in pecan after five years of cultivation in an orchard. The experiment was conducted in Santa Maria – Rio Grande do Sul, Brazil, in a pecan orchard planted with seedlings inoculated with these two species of truffles. The orchard was characterized in terms of soil physical and chemical properties and soil type. Initially non-inoculated plants, plants inoculated with Tuber aestivum (TA), and plants inoculated with Tuber brumale (TB) were evaluated for the percentage (%) of roots colonized by Tuber spp., other ectomycorrhizae, and non-mycorrhizal roots. A reduction in the colonization of both truffle species was observed five years after transplanting the seedlings to the orchard but they have the potential to maintain the ectomycorrhizal association with pecan seedlings.

2. Fungos ectomicorrízicos em plantações de nogueira-pecã e o potencial da truficultura no BrasilMarcelo Aloisio Sulzbacher, Jonas Janner Hamann, Diniz Fronza, Rodrigo Josemar Seminoti Jacques, Admir Jose Giachini, Tine Grebenc, Zaida Ines Antoniolli, 2019, izvirni znanstveni članek Povzetek: Os estudos envolvendo a nogueira-pecã têm evoluído consideravelmente nos últimos anos no Brasil. Esta cultura foi introduzida no país no início do século passado e tornou-se importante comercialmente após os anos de 1960, principalmente na região sul. A nogueira-pecã é comprovadamente um simbionte, formando diversas associações mutualísticas com fungos ectomicorrízicos do solo. Assim, a presente revisão tem como objetivos apresentar os estudos sobre os fungos ectomicorrízicos em plantações comerciais de nogueirapecã no Brasil, destacar a importância agrícola e ambiental desta simbiose, e o potencial da micorrização controlada da nogueira-pecã, visando à produção de espécies desejadas de trufas, notadamente do gênero Tuber, em pomares comerciais, uma atividade econômica de alta rentabilidade.

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

4. Ectomycorrhizal fungi from southern Brazil - a literature-based review, their origin and potential hostsMarcelo Aloisio Sulzbacher, Tine Grebenc, RJS Jacques, Zaida Ines Antoniolli, 2013, izvirni znanstveni članek 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.
