ABSTRACT
Within the family Amylocorticiaceae, conspicuous morphological affinities exist
among the previously defined species Irpicodon pendulus, Plicaturopsis crispa and Plicatura
nivea. With the aid of macro- and micro-morphological characters and phylogenetic
evidence based on 3-gene datasets, a comprehensive reassessment of generic boundaries
within these taxa was conducted. Upon reviewing the systematic position of the taxa
included, the three genera emerged as a well-defined monophyletic clade. Based on the
genetic divergence observed, coupled with the robust support for monophyly, similarities
in ecological roles, and congruence in macro- and micromorphological characteristics, we
suggest a revised genus concept that synonymizes Irpicodon (as well as Plicaturopsis) with
the earliest established genus Plicatura.
