Over 400 food resources from Brazil: evidence-based records of wild edible mushrooms.

Many species of mushroom-forming fungi have been harvested in the wild and used for food and medicine for thousands of years. In Brazil, the knowledge of the diversity of wild edible mushrooms remains scattered and poorly studied. Based on new samples, bibliographic records revision, and searches through the GenBank, we recorded 409 species of wild edible mushrooms in Brazil, of which 350 can be safely consumed and 59 are edible but with conditions.

Restinga ectomycorrhizae: a work in progress.

The Brazilian Atlantic Forest is one of the most biodiverse terrestrial ecoregions of the world. Among its constituents, restinga vegetation makes a particular case, acting as a buffer zone between the oceans and the forest. Covering some 80% of Brazilian coastline (over 7,300 km in length), restinga is a harsh environment where plants and fungi interact in complex ways that just now are beginning to be unveiled.

Biogeographic history of a large clade of ectomycorrhizal fungi, the Russulaceae, in the Neotropics and adjacent regions.

The biogeography of neotropical fungi remains poorly understood. Here, we reconstruct the origins and diversification of neotropical lineages in one of the largest clades of ectomycorrhizal fungi in the globally widespread family Russulaceae. We inferred a supertree of 3285 operational taxonomic units, representing worldwide internal transcribed spacer sequences.

Morpho-anatomical and molecular characterization of a native mycorrhizal species associated with () in the brazilian Atlantic Forest.

In this work, we characterize naturally occurring mycorrhizae formed by on in the Atlantic Forest in Brazil. We sequenced the rDNA ITS region from the mycorrhizae and basidiomata to identify both symbionts. mycorrhizae were up to 43 mm long, mostly simple, and unbranched to irregularly pinnate.

Reclassification of Corner (Basidiomycota: Agaricales) introducing the ant-associated genus gen. nov., Henn. and the corticioid fam. nov.

was formally proposed to group six coralloid and dimitic genera: (=, , , , and . Recent molecular studies have shown that some of the characters currently used in do not distinguish the genera. and have been removed, and a few other resupinate genera were added to the family.

Reclassification of Corner (Pterulaceae, Agaricales), contributions to Lachnocladiaceae and Peniophoraceae (Russulales) and introduction of gen. nov.

The genus was first introduced to accommodate two Brazilian species of coralloid fungi with affinities to Pterulaceae (Agaricales). Despite the coralloid habit and the presence of skeletal hyphae, other features, notably the presence of gloeocystidia, dichophyses and papillate hyphal ends, differentiate this genus from Pterulaceae Fieldwork in Brazil resulted in the rediscovery of two coralloid fungi identifiable as , the first verified collections of this genus since Corner's original work in the 1950s. Molecular phylogenetic analyses of nrITS and nrLSU sequences from these modern specimens revealed affinities with the /peniophorales clade in the Russulales, rather than Pterulaceae.

Fistulinella ruschii, sp. nov., and a new record of Fistulinella campinaranae var. scrobiculata for the Atlantic Forest, Brazil.

Fistulinella is a small genus of boletoid fungi in the subfamily Austroboletoideae in the order Boletales. In this paper, F. ruschii from the Atlantic Forest is proposed as new to science and F.

Study on species of phylloporus I: Neotropics and North America.

Seventeen out of the 24 taxa of Phylloporus (Boletaceae) known from the Neotropics are presented here. Complete descriptions, illustrations and a key to the 17 species are provided. Phylloporus alborufus is newly described, and an unnamed species is also described from Costa Rican oak forests.

Pacific boletes: implications for biogeographic relationships.

The obligate association of boletes with their plant partners is critical to understanding biogeographic distribution of these fungi. Only in rare instances are boletes not obligatory associates of plants; the majority are presumed or proven partners in obligate symbioses with a variety of plants. The array of plant-associated distributions provides a potential handle for evaluating bolete distribution on a global scale.

Taxonomy of displaced species of Tubaria.

A taxonomic treatment of vinaceous and reddish species of Tubaria (Agaricales) is presented based on morphology and nucleotide sequences. Accessions from western North America, Europe, Central America, the Caribbean and Australia are compared. Phylogenetic analysis of the 25S rRNA gene and internal transcribed spacer (ITS) regions demonstrates that Tubaria is not monophyletic.
