II. Systematics of Pucciniomycotina
Most early treatments of basidiomycetes recog-
nized one main division in the group, between
those species that formed holobasidia (homo-
basidiomycetes) and those with phragmobasi-
dia (heterobasidiomycetes). However, analyses
of 5S ribosomal RNA sequences by Walker
and Doolittle (Walker and Doolittle 1982 )
divided Basidiomycota into two groups, not
by any traditional characters but by whether
they possessed simple pores or dolipores.Agaricoslbum hyphaenes

*******PUCCINIOMYCOTINA*Fig. 10.1Phylogenetic resolution of Pucciniomycotina
classes. Tree based on maximum likelihood analyses of
combined nuclear ribosomal small and large subunits
and translation elongation factor 1-alpha DNA
sequences. Ascomycota sequences included as out-
groups; representative Agaricomycotina and Ustilagi-
nomycotina sequences included to show monophyly of
Pucciniomycotina. Asterisk (*) denotes nodes that have
received strong (>80 %) support in the analyses of
Aime et al. ( 2006 ), Padamsee et al. ( 2012 ), and Schell
et al. ( 2011 ). Backbone resolution remains poor within
Pucciniomycotina. Figure adapted from Schell et al.
