- Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.

- The Natural Park of “Las Batuecas-Sierra de Francia”, recently declared Biosphere Reserve in 2006, is situated in the south of Salamanca province in the central and occidental part of the Iberian Peninsula (40º 26' and 40º 35 N latitude, 5º 57' and 6º 15' W longitude) with and extension of 320 km2. The area presents a typical Mediterranean humid climate and the next main forest formations are present: deciduous forests of Quercus ilex subsp. ballota (Desf.) Samp., Quercus suber L., Quercus faginea Lam., Quercus pyrenaica Willd., Quercus robur L., Castanea sativa Mill., Arbutus unedo L., Eucalyptus camaldulensis Denhn.; coniferous forests of Pinus pinaster Aiton, Pinus sylvestris L., Juniperus oxycedrus L.; riparian formations of Alnus glutinosa (L.) Gaertn., Salix spp. and Populus spp., among others. Despite of its Biosphere Reserve declaration (mainly based on the interesting mediterranean vegetal and animal communities and socio-cultural patrimony) there are really few fungal studies in the area and this is the first long term systematized study regarding corticioid fungi.

- Gloeocystidiellum rajchenbergii, Hypochnicium patagonicum, Pteridomyces valdivianus, and Stereum greslebinii are described as new species from the Chilean Patagonia. An annotated checklist of corticioid fungi from Chile, listing 94 species with notes on distribution and ecology, scheduled for regular update, is available from http://corticioids.webs.com/checklists.htm.

Phylogenomics, divergence times and notes of orders in Basidiomycota

- Basidiomycota is one of the major phyla in the fungal tree of life. The outline of Basidiomycota provides essential taxonomic information for researchers and workers in mycology. In this study, we present a time-framed phylogenomic tree with 487 species of Basidiomycota from 127 families, 47 orders, 14 classes and four subphyla; we update the outline of Basidiomycota based on the phylogenomic relationships and the taxonomic studies since 2019; and we provide notes for each order and discuss the history, defining characteristics, evolution, justification of orders, problems, significance, and plates. Our phylogenomic analysis suggests that the subphyla diverged in a time range of 443–490 Myr (million years), classes in a time range of 312–412 Myr, and orders in a time range of 102–361 Myr. Families diverged in a time range of 50–289 Myr, 76–224 Myr, and 62–156 Myr in Agaricomycotina, Pucciniomycotina, and Ustilaginomycotina, respectively. Based on the phylogenomic relationships and divergence times, we propose a new suborder Mycenineae in Agaricales to accommodate Mycenaceae. In the current outline of Basidiomycota, there are four subphyla, 20 classes, 77 orders, 297 families, and 2134 genera accepted. When building a robust taxonomy of Basidiomycota in the genomic era, the generation of molecular phylogenetic data has become relatively easier. Finding phenotypical characters, especially those that can be applied for identification and classification, however, has become increasingly challenging.
