What Do the First 597 Global Fungal Red List Assessments Tell Us about the Threat Status of Fungi?

Fungal species are not immune to the threats facing animals and plants and are thus also prone to extinction. Yet, until 2015, fungi were nearly absent on the IUCN Red List. Recent efforts to identify fungal species under threat have significantly increased the number of published fungal assessments. The 597 species of fungi published in the 2022-1 IUCN Red List update (21 July 2022) are the basis for the first global review of the extinction risk of fungi and the threats they face. Nearly 50% of the assessed species are threatened, with 10% NT and 9% DD. For regions with a larger number of assessments (i.e., Europe, North America, and South America), subanalyses are provided. Data for lichenized and nonlichenized fungi are also summarized separately. Habitat loss/degradation followed by climate change, invasive species, and pollution are the primary identified threats. Bias in the data is discussed along with knowledge gaps. Suggested actions to address these gaps are provided along with a discussion of the use of assessments to facilitate on-the-ground conservation efforts. A research agenda for conservation mycology to assist in the assessment process and implementation of effective species/habitat management is presented

First record of Daedalea ryvardeniana Drechsler-Santos & Robledo (Agaricomycetes, Polyporales, Fomitopsidaceae) in the Caatinga area of Bahia, Brazil

Daedalea ryvardeniana (Agaricomycetes, Polyporales, Fomitopsidaceae) is reported for the first time in the Caatinga area of Bahia. The Caatinga is a phytogeographical domain in Brazil and its diversity of polyporoid fungi is being gradually discovered through the findings of new species and new occurrences

Global phylogenetic and morphological reassessment of Fomitiporella s.l. (Hymenochaetales, Basidiomycota): taxonomic delimitation of Fomitiporella s.s. and segregation of Rajchenbergia, gen. nov

Fomitiporella has been phylogenetically studied in order to taxonomically treat it more naturally. In order to establish Fomitiporella s.s., studies on the holotype of F. umbrinella (the type species of Fomitiporella), and new specimens from the type locality, were carried out. Additionally, the holotype of Fuscoporella coruscans (the type species of Fuscoporella) was studied. A new morphological conceptual delimitation of Fomitiporella s.s. is presented, with a more restricted distribution pattern, and Fuscoporella is chosen as a synonym of Fomitiporella. Moreover, Rajchenbergia, gen. nov. is segregated from Fomitiporella s.l. based on morphology, phylogenetic relationships and host distribution. Taxonomic implications for the group and other related taxa are discussed. Fomitiporella americana is synonymized with F. umbrinella, F. micropora with Fomitiporella coruscans, comb. nov., and F. melleopora is now in Tropicoporus melleoporus, comb. nov., based on type and reference material studies.Fil: Salvador Montoya, Carlos Alberto.

Neotropical Studies on Hymenochaetaceae: Unveiling the Diversity and Endemicity of Phellinotus

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. The members of this genus, along with six other well-established genera and some unresolved lineages, are the current representatives of the ‘phellinotus clade’. On the other hand, based on a two-loci phylogenetic analysis, some entities/lineages of the ‘phellinotus clade’ have been found in Fomitiporella s.l. In this work, we performed four-loci phylogenetic analyses and based on our results the genera of the ‘phellinotus clade’ are shown to be monophyletic groups. In addition to the natural groups confirmed as different genera, morphological revisions, phylogenetic relationships, and host distribution of different specimens resembling P. neoaridus and P. piptadeniae revealed three new species in the Phellinotus genus, referred to here as P. magnoporatus, P. teixeirae and P. xerophyticus. Furthermore, for P. piptadeniae a narrower species concept was adopted with redefined morphological characters and a more limited distribution range. Both P. neoaridus and P. teixeirae have a distribution range restricted to seasonally dry tropical forests in South America. Additionally, based on detailed morphological revisions Phellinus badius, Phellinus resinaceus, and Phellinus scaber are transferred to the Phellinotus genus. The geographic distribution and host range of the genus are then discussed

Ophiocordyceps neonutans sp. nov., a new neotropical species from O. nutans complex (ophiocordycipitaceae, ascomycota)

Ophiocordyceps nutans is an entomogenous fungus growing on true bugs (Hemiptera), which has a presumed worldwide distribution. During forays of entomogenous fungi in Brazil, specimens morphologically similar to O. nutans were collected from the Atlantic Forest and Cerrado domains of Neotropical region. Morphological comparisons, as well as molecular phylogenetic analyses using ITS, led us to conclude that the neotropical specimens represent a new species Ophiocordyceps neonutans. The Neotropical occurrence of this taxon and its taxonomic implications are re-evaluated here. We discuss O. nutans as a species complex with distinct geographic lineages and host specificity. In addition, Barcoding gap analysis suggests that the different lineages have a great genetic distance between them.Fil: Friedrich, Raquel C. S..
