A second genus in Chlorociboriaceae is described here as Brahmaculusgen. nov. Macroscopically distinctive, all species have bright yellow apothecia with several apothecial cups held on short branches at the tip of a long stipe. The genus is widely distributed across the Southern Hemisphere; the four new species described here include two from Chile (B. magellanicussp. nov., B. osornoensissp. nov.) and one each from New Zealand (B. moonlighticussp. nov.) and Australia (B. packhamiaesp. nov.). They differ from species referred to Chlorociboria, the only other genus in Chlorociboriaceae, in their terrestrial habitat and ascomata that are noticeably more hairy than the known Chlorociboria species, most of which have apothecia with short, macroscopically indistinct hair-like elements. Based on our analyses, Chlorociboria as accepted here is paraphyletic. Additional study is needed to clarify where alternative, monophyletic generic limits should be drawn and how these genera may be recognised morphologically. Also described here are three new Chlorociboria spp. from New Zealand (C. metrosiderisp. nov., C. solandrisp. nov., C. subtilissp. nov.), distinctive in developing on dead leaves rather than wood and in two of them not forming the green pigmentation characteristic of most Chlorociboria species. New Zealand specimens previously incorrectly identified as Chlorociboria argentinensis are provided with a new name, C. novae-zelandiaesp. nov.

“…However, Cortinarius diversity in the Southern Hemisphere remains insufficiently studied compared with the diversity in the Northern Hemisphere (Peintner et al 2004;Garnica et al 2005). Cortinarius is the most speciesrich genus in southern South American Nothofagaceae forests, with approximately 250 species described from the region to date (Garnica et al 2002(Garnica et al , 2003Romano and Lechner 2014). The earliest publications of South American Cortinarius species are from Spegazzini (1887aSpegazzini ( , 1887b, whereas the largest contribution was made by Moser and Horak (1975) and Horak (1980) from Andino-Patagonian forests.…”

New species ofCortinariussect.Austroamericani, sect. nov., from South American Nothofagaceae forests

et al. 2018

In this study, we document and describe the new Cortinarius section Austroamericani. Our results reveal high species diversity within this clade, with a total of 12 recognized species. Of these, only C. rufus was previously documented. Seven species are described as new based on basidiomata collections. The four remaining species are only known from environmental sequences. All examined species form ectomycorrhizal associations with species of Nothofagaceae and are currently only known from Argentinean and Chilean Patagonia. The phylogenetic analysis based on the nuc rDNA internal transcriber spacer (ITS1-5.8S-ITS2 = ITS) and partial 28S gene (28S) sequences shows that this section is related to other taxa from the Southern Hemisphere. Species in this group do not belong to subg. Telamonia, where C. rufus was initially placed. Cortinarius rufus and the newly described C. subrufus form a basal clade within sect. Austroamericani that has a weakly supported relationship with the core clade. Because the two species are morphologically similar to species from the core clade and share their distribution and Nothofagaceae associations, we include them here as part of sect. Austroamericani sensu lato (s.l.) until more material is available to refine the delimitation.

Basidiome production of ectomycorrhizal and saprophytic agaricoid fungi respond differently to forest management

Forest management generates border effects in mature dense forests. How agaricoid fungi species react to this disturbance depends on climatic and site conditions, as well as forest management system used and its intensity. We compared abundance and richness of ectomycorrhizal and saprophytic species in managed and unmanaged stands in Nothofagus pumilio (Poepp. & Endl.) Krasser forests of Patagonia, Argentina. We found that basidiome abundance and richness of ectomycorrhizal and saprophytic species were favoured by different forest structure and climatic factors. Ectomycorrhizal species basidiome production was significantly correlated to mean relative humidity of the 15 days prior to sampling and tree density (number of trees per hectare) existing prior to management activities. The latter implies that the tree density an ecosystem is capable of sustaining is crucial to the establishment of ectomycorrhizal species. Saprophytic species were favoured by the increased amount of woody material generated by logging together with maximum temperature in the 15 days prior to sampling and mean annual precipitation. Our results indicate that agaricoid fungi are not affected by low- to medium-intensity forest management, establishing the forestry level that fungal community can tolerate without loss of species in Patagonia.
