“…This discrepancy may be the result of the poor dispersal ability of fungi, or the wider climatic tolerances of fungi compared with macroorganisms. For example, many ectomycorrhizal fungi persist in novel climates but first require introductions to establish (44). It is possible that host species range accounts for differences in ectomycorrhizal community structure across large geographic regions.…”

“…The Pinaceae are ideal for exploring environmentcommunity-function relationships across the fungal kingdom because they have a broad distribution across North America and show low levels of host specificity for mycorrhizal fungi within the family (47,58). For example, North American pines readily associate with European ectomycorrhizal fungi (44), and co-occurring Pinaceae and angiosperms often share most common ectomycorrhizal fungi (59). Plots were chosen with the help of local experts to find mature stands with high dominance of a single Pinaceae species at sites spanning the North American continent (Fig.…”

Identifying the ecological processes that structure communities and the consequences for ecosystem function is a central goal of ecology. The recognition that fungi, bacteria, and viruses control key ecosystem functions has made microbial communities a major focus of this field. Because many ecological processes are apparent only at particular spatial or temporal scales, a complete understanding of the linkages between microbial community, environment, and function requires analysis across a wide range of scales. Here, we map the biological and functional geography of soil fungi from local to continental scales and show that the principal ecological processes controlling community structure and function operate at different scales. Similar to plants or animals, most soil fungi are endemic to particular bioregions, suggesting that factors operating at large spatial scales, like dispersal limitation or climate, are the first-order determinants of fungal community structure in nature. By contrast, soil extracellular enzyme activity is highly convergent across bioregions and widely differing fungal communities. Instead, soil enzyme activity is correlated with local soil environment and distribution of fungal traits within the community. The lack of structure-function relationships for soil fungal communities at continental scales indicates a high degree of functional redundancy among fungal communities in global biogeochemical cycles.T he structure and function of ecological communities are intimately linked, such that the number and identity of species within a community often affect the key ecosystem properties of primary productivity (1), resistance and resilience to disturbance (2), and rates of nutrient cycling (3). However, understanding the extent to which structure-function relationships hold across communities and over large spatial scales continues to be a major goal of ecological research. Identifying these relationships for microbial organisms is particularly critical, because these organisms control rates of key ecosystem processes (the cycling of nitrogen, phosphorus, and carbon) (4) and directly affect the community structure of plants and animals through pathogenic or mutualistic interactions (5). As such, microbial activity is also intrinsic to Earth system models that inform citizens and policy makers of ecosystem dynamics and energy exchange between the biosphere and the atmosphere (6). As in plant communities of tropical rainforests (7), the incredible number of microbial taxa on Earth has been a challenge for understanding the link between diversity and function. Advances in DNA sequencing technology have recently allowed for a robust characterization of bacterial biogeographic patterns (8); however, to date, studies have examined structure-function relationships at a fixed scale (9-12). As a result, it is not yet clear how microbial function is linked to largescale biogeographic patterns, whether or not this link is a more reliable determinant of microbial function in global biogeochemical cycl...

“…Based on molecular evidence, Geml et al (2012) concluded that longdistance dispersal of some ECM fungi, including Sebacina species in the Northern Hemisphere, may have played a major role in their phylogeographic history. Human-caused introductions of ECMs are common and widespread, and may exceed 200 species (Vellinga et al 2009). However, species with inconspicuous fruitbodies, as most sebacinalean taxa, are rarely or not reported at all.…”

A historical retrospect and a taxonomic update will deal with Sebacina s.l. and s.str., Craterocolla, Efibulobasidium, Serendipita, Trem ell odendron, Trem ell oscypha, Tremellostereum, and Piriformospora, the Sebacinaceae, and the Sebacinales. Phylogenetic hypotheses for the order and subordinal taxa are discussed, including environmental sequence taxa. The cryptic biodiversity in Sebacinales is extensive but mostly unresolved with respect to the species involved.

Taxonomic studies of Amanita muscaria (L.) Lam (Amanitaceae, Agaricomycetes) and its infraspecific taxa in Brazil

We analyzed specimens identifi ed as Amanita muscaria, some recently collected and others already deposited in herbaria, in Brazil. We concluded that two subspecies of A. muscaria occur in Brazil: A. muscaria var. muscaria; and A. muscaria var. fl avivolvata. Th e fi rst taxon was found in association with Castanea sativa, and the second (one specimen only) was found in association with Pinus and Eucalyptus spp. Morphologically, A. muscaria var. fl avivolvata is distinguished by a shallower subhymenium and by basidiospores that are more elongated than are those of A. muscaria var. muscaria, which is the more widely known subspecies. We present descriptions, discussions, illustrations and a dichotomous key for these two subspecies. Acta Botanica Brasilica 27(1): 31-39. 2013.
