“…Atroporus was proposed by Ryvarden (1973) based on swollen binding hyphae in the context of the type species, but this characteristic was considered too vaguely defined for a genus description [ 33 ]. Atroporus was later amended by Palacio, Robledo, Reck & Drechsler-Santos (2017), using basidiospore descriptions and Melzer reagent reaction of the skeletal-binding hyphae in the trama [ 17 ].…”

“…Several taxa within the morphological groups have been newly amended, proposed and accepted, as independent genera within the “Melanopus” group. The new genera are Atroporus Ryvarden (1973) [ 17 ], Picipes Zmitr. & Kovalenko (2016) [ 18 ], and Neodictyopus Palacio, Robledo & Drechsler-Santos (2017) [ 17 ].…”

We believe it is important to continue decrypting the species described within Polyporus P. Micheli ex Adans that do not match Micheli’s original description but are part of the original morphological groups, in order to unveil their true genetic relationships.…”

Taxonomy of the major rhizomorphic species of the “Melanopus group” within Polyporaceae in Yasuní National Park, Ecuador

et al. 2021

Yasuní National Park in Ecuador is one of the most biodiverse places on earth. The fungi in this tropical rainforest are also diverse but have received little research attention. This research paper focuses on an important group of fungi in the family Polyporaceae and examines the genera Polyporus, Atroporus, and Neodictyopus that form aerial melanized cord-like structures called rhizomorphs. Phylogenetic analyses, macro and micromorphological descriptions of basidiomata and rhizomorphs, as well as cultural characterization were completed to better understand these ecologically important fungi. Here we describe four new species: Atroporus yasuniensis, Atroporus tagaeri, Neodictyopus sylvaticus, and Polyporus taromenane, and a new variety Polyporus leprieurii var. yasuniensis. The information presented in this study adds important new knowledge about the unusual rhizomorph producing fungi found in Yasuní National Park, Ecuador and other tropical rainforests.

Polyporus subpurpurascens is a rare Neotropical species characterized by deep purplish pilear surface and radially elongated pores. This study analyzed Neotropical specimens from Argentina, Bolivia and Brazil by applying detailed morphological examination and phylogenetic analyses. We conclude that P. subpurpurascens is a species of Neofavolus, and N. subpurpurascens is proposed as a new combination. New records from Argentina and Bolivia, a detailed description, and photographs of the species are included.

Six strains belonging to five species of Polyporus (P. arcularius, P. arcularioides, P. tricholoma, P. cfr. tricholoma, and P. varius), collected from an Atlantic Forest area in Misiones (Argentina), where species usually grow exposed to high temperatures and humidity, were identified by morphological and molecular analyses. P. tricholoma (BAFC 4536) and P. arcularioides (BAFC 4534) were selected by their lignin-degrading enzyme production, their ability to produce primordial of basidiomes under submerged fermentation, and the decrease in lignin content caused in Poplar wood (up to 29% after 45 days). Among several variables evaluated with a Plackett-Burman design (glucose, copper, vanillic acid and manganese concentration, incubation period, and light incidence), the most important factor affecting laccase and Mn-peroxidase (MnP) production by both strains, was light incidence. Light induced fruit body development but diminished laccase and MnP production. Moreover, a modified isoenzymatic laccase pattern was observed, showing additional isoenzymes when fungi were cultivated under darkness and differences in optimal temperature. Although the studied strains did not produce high laccase and MnP titers (uppermost detected 4230 and 90 U L , respectively), their laccases showed thermal stability and optimal temperature above 70 °C, representing an interesting source in the search of thermo-tolerant enzymes for biotechnological applications.
