ABSTRACT
Three species of lichenized basidiomycetes in the Dictyonema clade from southeastern
North America are described as new to science: Cyphellostereum georgianum,
C. jamesianum and Dictyonema lawreyi, all with a crustose-filamentous growth form.
Based on ITS sequences, the species form well-supported monophyletic clades in a phylogeny
and are represented by at least two specimens each. They are also distinguishable
by morphological and anatomical characters. These new findings emphasize the importance
of lichenological studies in North America, especially in historically understudied taxonomic
groups, such as basidiolichens. This study is dedicated to James D. Lawrey on the
occasion of his 70th birthday.
