The phylogeny of Phylloporus (Boletaceae) has not been well studied, and the taxonomic relationships of this genus have varied considerably among authors. The following study presents phylogenetic relationships of Phylloporus based on two nuclear ribosomal DNA regions, ITS and LSU. The ITS dataset includes 39 collections and the LSU dataset contains 50(More)
Plant pathogenic fungi are a large and diverse assemblage of eukaryotes with substantial impacts on natural ecosystems and human endeavours. These taxa often have complex and poorly understood life cycles, lack observable, discriminatory morphological characters, and may not be amenable to in vitro culturing. As a result, species identification is(More)
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(More)
The Atlantic forest is a biodiversity hotspot and harbors a great variety of fungi, many still undiscovered. Basidiomes were collected in coastal restinga on remnants of Atlantic forest in Florianópolis Island, Santa Catarina. This is the first record of Austroboletus festivus for the state and expands its geographic distribution, previously known in Brazil(More)
There are moments within the process of creating an artifact, for instance at the initial requirements gathering or in the assessment phase, that users input data is collected. There may be an impact directly on the results of the analysis of this data if, for some reason, this data input is not accurate. This paper will focus on a specific phenomenon,(More)
