| Descripción: | This paper highlights and expands on some of the major points of good taxonomic practice. Myxomycete species concepts are reviewed, monotypic genera are discussed and critiqued, and case study examples are given for Badhamiopsis ainoae, Protophysarum phloiogenum, and Trabrooksia applanata. Monotypic genera are suggested for DNA sequencing to resolve the correct taxonomic rank in myxomycete classification. Fossil evidence of myxomycetes found in amber is evaluated and discussed for the first time. Perichaena species represented by P. brevifila, P. microspora, P. pedata, and P. syncarpon, are restricted to leaf litter habitats and serve as examples of fruiting seasonality patterns and ecological differences based on detailed field observations recorded in collection data. This additional ecological information can supplement morphological differences in distinct species. The future of myxomycete systematics requires a shift from descriptive taxonomy to in-depth studies using hypotheses that test phylogenetic relationships, biogeographical patterns of distribution, and the restriction of species to habitats with special ecological characteristics. |
