Abstract
This study is a systematic assessment of ten species of ectomycorrhizal fungi of the genus Amanita (Amanitaceae, Agaricales, Basidiomycota) from the lowland tropical rainforests of the Guiana Shield and Central Africa. Fungi were collected in each of the above regions, analyzed morphologically, and compared to the literature on Amanita diversity worldwide. All species addressed herein are given full formal taxonomic descriptions including complete macro- and microscopic character profiles, habit, habitat, and distribution. Phylogenetic assessments using ribosomal DNA and protein coding genes are provided for Guiana Shield taxa, and sequence data for two non-protein coding regions, the internal transcribed spacer (ITS) and nuclear ribosomal large subunit (nrLSU) are provided for Central African taxa. to support infrageneric placement of each taxon. Chapter one describes three new species from the Guiana Shield: A. cyanochlorinosma, A. fulvoalba, and A. guyanensis. Chapter two describes four epitypes of otherwise poorly known Central African species: A. echinulata, A. fulvopulverulenta, A. robusta, and A. bingensis, and three new species from Cameroon: A. minima, A. leucolamellata, and A. goossens-fontanae. Each chapter is a manuscript that has been published in, or submitted to, a peer-reviewed mycological journal.
