Phellinotus, a neotropical genus of wood-decay fungi commonly found on living members of the Fabaceae family, was initially described as containing two species, P. neoaridus and P. piptadeniae.

- Two proposals have been put forward to allow DNA sequences to be used as types for naming certain fungi, which could fundamentally alter the definition of nomenclatural types and lead to various issues in scientific reproducibility and nomenclatural instability.
- The authors argue against these proposals, suggesting that they would not effectively address the challenges of naming taxa based solely on DNA and propose instead that formulas for naming candidate taxa could be a better solution without changing existing nomenclature rules.
Polyporus dictyopus, with a large number of heterotypic synonyms, has been traditionally considered a species complex, characterized by wide morphological variation and geographic distribution. Thus, neotropical specimens previously identified as P. dictyopus from Amazonia, Cerrado and Atlantic Forest biomes were studied based on detailed macro- and micromorphological examination and phylogenetic analyses, using distinct ribosomal and protein-coding genomic regions: the nuclear ribosomal internal transcribed spacer (nrITS), nuclear ribosomal large subunit (nrLSU), and RNA polymerase II second subunit (RPB2).

Heterostachys ritteriana (Amaranthaceae), a halophyte shrub growing in arid environments such as "Salinas Grandes" (Córdoba, Argentina), appears to be the main source of organic matter in the area. Little is known regarding the microorganisms associated with H.
