Preliminary notes on Pluteus phylogeny
Minnis, Andrew M.; Sundberg, Walter J.
Pluteus is a cosmopolitan agaric genus that is a saprotroph found typically on xyloid substrates. Few studies have addressed its phylogeny below the generic rank. A review of these phylogenetic studies of Pluteus is offered. Additionally, a primarily morphology-based phylogeny of the genus is produced. The implications of the results as well as the weaknesses of this approach are discussed, especially in regards to subdivisional classifications of Pluteus and character evolution. The congruence of these results with those based on molecular data is discussed. The current widely accepted Pluteus classification scheme is more or less supported, and no changes are proposed here. This study provides a framework and considerations for future analyses utilizing other modern techniques such as DNA-based phylogeny as the presented hypotheses and morphological data may be easily incorporated into such works.
