A new lineage in Pucciniomycotina: class Tritirachiomycetes, order Tritirachiales, family Tritirachiaceae

Based on multiple gene analyses (nuclear large subunit, nuclear small subunit, internal transcribed spacer region including the 5.8 s subunit rDNA, and translation elongation factor 1α) and septal pore ultrastructure we describe a new lineage of Pucciniomycotina consisting of a new class, Tritirachi...

Description
Summary:Based on multiple gene analyses (nuclear large subunit, nuclear small subunit, internal transcribed spacer region including the 5.8 s subunit rDNA, and translation elongation factor 1α) and septal pore ultrastructure we describe a new lineage of Pucciniomycotina consisting of a new class, Tritirachiomycetes, new order, Tritirachiales, and new family, Tritirachiaceae. Tritirachium dependens, T. oryzae, T. roseum (reintroduced), T. cinnamomeum and two unidentified species are recognized. Phylogenetic analyses do not support existing morphological circumscription of some species, and the available evidence suggests that morphological evaluation alone is not adequate for species identification.
