Abstract

The phylogeny of the families Lecanoraceae and Bacidiaceae (Lecanorales, Ascomycota) was investigated using nuclear small subunit ribosomal DNA sequences. Phylogenetic estimations were performed with maximum parsimony and maximum likelihood optimality criteria. In the most parsimonious and most likely reconstructions, the Bacidiaceae sensu Hafellner 1988 forms a monophyletic group and the Lecanoraceae sensu Hafellner a paraphyletic group. The genera Tephromela and Scoliciosporum appear to belong outside these families. A Kishino-Hasegawa test indicated that a phylogeny where the Bacidiaceae and Lecanoraceae, excluding Tephromela and Scoliciosporum, are both monophyletic cannot be rejected. Three hypotheses were rejected, viz. (1) that the Lecanoraceae and Bacidiaceae together form a monophyletic group, (2) that both the Lecanoraceae (incl. Scoliciosporum) and Bacidiaceae (incl. Tephromela) are monophyletic, and (3) that the ascus apex anatomy reflects phylogeny. The suborder Lecanorineae is paraphyletic unless the Stereocaulaceae and Cladoniaceae are included. One or both of the Bacidia- and Lecanora-types of ascus have probably evolved at least twice.
