mor - Welcome to Mor

Welcome. mor is an ongoing project based in the Hibbett lab of Clark University that seeks to produce continually updated phylogenetic trees and classifications for the homobasidiomycetes (mushroom-forming fungi) on an automated basis. In brief, mor retrieves, screens, aligns, and analyzes nuc-lsu rDNA sequences of homobasidiomycetes from GenBank, and then parses out the contents of individual clades using node-based phylogenetic taxon definitions. Thus, mor represents a step toward automated phylogenetic taxonomy. For more information about homobasidiomycete phylogeny, visit the Tree of Life Web Project page for homobasidiomycetes.

mor creates two phylogenetic trees each week: an unconstrained jacknife neighbor-joining tree, and a topologically constrained consensus maximum parsimony tree. The parsimony tree is used to delimit the clades.

On the following pages, you can view the NJ and MP trees, link to GenBank, search for images of fungi on the internet, view individual clade pages, download alignments and treefiles (for the entire dataset or individual clades), post comments, and create new clade definitions. Please note that some files are quite large (about 6 MB) and can take some time to load.

the current

differ in some
regards from the
topology shown
here. In addition, some
sequences are not placed
into any of the clades
shown here (e.g., Jaepia
argillacea); these can be viewed
at the incertae sedis page.
