Expanding the occurrence of Parmotrema enteroxanthum ( Parmeliaceae , lichenized Ascomycota ) in South America: first record from Brazil, and notes on distribution and conservation assessment
Parmotrema enteroxanthum is a restricted distribution foliose lichen, easily recognized by its yellow medulla and salazinic acid content. Previously known only from Venezuela, Colombia, and Bolivia, its distribution in South America remains poorly understood. This study documents the first record…

From one to five putative species: an unexpected high genetic diversity in Usnea flavocardia (lichenized Ascomycetes, Parmeliaceae ) with the discovery of a new clade within the subgenus Usnea s.str.
In this study, we analyzed the genetic diversity within Usnea flavocardia , a widespread species found in all continents except Antarctica. The species is characterized by a shrubby thallus growth form, the presence of soralia, a yellow central axis and/or the presence of red dots on the cortex…

Novel and rare microfungi associated with Acrocomia intumescens and Attalea oleifera , native Brazilian palm trees
Palm trees are critical substrates for a diverse array of microfungi, with new species frequently described from these hosts. However, systematic surveys of palm-associated microfungi remain limited, particularly in tropical South America. In a study of microfungi colonizing decomposing rachises…

Yunnanomyces syagri sp. nov. ( Sympoventuriaceae , Venturiales ) on Syagrus coronata , an endemic Brazilian palm
While surveying saprotrophic microfungi on Syagrus coronata ( Arecaceae ), an endemic palm in Brazil, an unusual fungus was identified occurring on the dead leaves of this plant. Morphologically, it showed the key traits of Yunnanomyces , including semi-macronematous conidiophores, integrated…

First European record of Sticta arenosella and new Central European records of Sticta fuliginoides
The genus Sticta has recently undergone significant taxonomic revisions in Europe, yet central regions such as Switzerland were not included in those revisions. To assess the diversity of the species complex Sticta fuliginosa in Switzerland, we used an integrative taxonomic approach combining…

Bryocentria insolens ( Hypocreales ) – a new bryophilous ascomycete on Lewinskya and a preliminary phylogenetic analysis of European Bryocentria
The bryophilous genus Bryocentria comprises nineteen species of mostly hepaticolous parasites exhibiting a range of distinctive ascospore features and host-parasite interactions. While Bryocentria has been relatively well studied in Europe, with several common and well-known species, new taxa…

Morphological variation and phylogenetic position of Vatica rassak ( Dipterocarpaceae ) based on the trn L- trn F region
Vatica rassak is one of the most exploited species of the genus Vatica for its wood and resin. The species exhibits high morphological variations across their range of distribution that crosses the border of the Wallace’s line. To understand whether such variations may imply infra-specific…

Mycena luxaustralis , a new bioluminescent species in section Sacchariferae from southern Chile
Bioluminescent fungi emit light through chemical luminescence of fungal tissues. More than 100 species of bioluminescent fungi have been described in five distinct groups of Agaricales : Omphalotus , Armillaria , the Lucentipes lineage within Marasmiineae , the Eoscyphella lineage, and the mycenoid…

Diploicia christinae sp. nov. ( Ascomycota : Caliciales : Caliciaceae ), an overlooked lichen species from Bermuda
A crustose lichen species new to science – overlooked by previous workers – is formally described. This new species, Diploicia christinae , differs from all other species in the genus by its narrow lobes (< 1 mm) and its effuse soralia that contain consistently white soredia. Its secondary…

Less is better than more: reassessing the monotypic nature of Irpicodon ( Amylocorticiaceae , Basidiomycota )
Within the family Amylocorticiaceae , conspicuous morphological affinities exist among the previously defined species Irpicodon pendulus , Plicaturopsis crispa and Plicatura nivea . With the aid of macro- and micro-morphological characters and phylogenetic evidence based on 3-gene datasets, a…

Auricularia (wood ear mushroom) genus: a contribution to classification and new species records for Iran and world
Auricularia is one of the most widely distributed macrofungi, regarded as an edible medical mushroom, and is the third largest cultivated mushroom in the world due to its high nutrition and bioactivity properties. This research specifies the taxonomic status of this genus in Iran for the first…

The genus Camillea ( Xylariales ) in Argentina’s Yungas: a comprehensive morphological study with two new species and identification key
From an exhaustive taxonomic survey of Xylariales carried out in the subtropical montane forest of the Argentine northwest (“Las Yungas”), a first comprehensive revision of Camillea for the country is presented. Based on a new combination of sexual and asexual morphology, C. hladkiae and C…

High diversity of Trichonectria ( Hypocreales ) inhabiting Usnea in Bolivia
The Neotropics, particularly mountain cloud forests, are characterized by a high diversity of microfungi that inhabit lichens. However, based on our field studies, many of these microfungi remain undescribed, and their phylogenetic relationships are poorly understood. This study focuses on Bolivian…

Novel and uncommon bryophilous fungi from Brazil
Bryophilous fungi are an understudied group with unknown biodiversity in tropical regions, and are often underestimated worldwide. In Brazil, research on this ecological group has primarily focused on the southern and southeastern regions. During a survey of bryophilous fungi in the northeastern…

The morphology, phylogeny, and distribution of the pine-associated sequestrate fungus Lactarius cinnabarinus comb. nov. (= Zelleromyces cinnabarinus) in the United States, Argentina and Brazil
The sequestrate fungus Zelleromyces cinnabarinus was originally found beneath pines and was described from Louisiana, USA. Here we re-evaluate the morphology, taxonomy, and distribution of this species based on new specimens across the native range in the southeastern United States (USA), as well…

Discovery of the first lichenized fungus in the family Chaetothyriaceae ( Ascomycota ), Ceramothyrium ryukyuense sp. nov.
Ceramothyrium ryukyuense ( Chaetothyriaceae ) is described as a new species from Okinawa, southern Japan. It is characterized by subglobose minute ascomata (up to 110 μm diam.) covered with a brown mycelial pellicle, small ellipsoid 1(–2)-septate ascospores (8.7–13.8 × 3.4–4.9 μm) within a small…

Sticta puebloensis (Lichenized Ascomycota: Peltigeraceae ) a New species of Sticta from the American Southwest
In a continued effort to dismantle the Sticta fuliginosa morphodeme of western North America, we performed an extensive sampling throughout the mountainous regions of the southwestern states of the USA: Arizona, Colorado, and New Mexico. Recent studies have concluded the genus Sticta has extensive…

Advancing the understanding of Tanzania's lichen flora: a comprehensive review
Tanzania possesses various types of forest ecosystems, such as miombo woodlands, mangroves, and montane forests, which support a wide range of biodiversity, including lichens. In our recent studies of lichens in Tanzania, we have observed a significant lack of documented records. Therefore, we are…

Revision of Marchantiana ( Caloplacoideae , Teloschistaceae ) – a misconceived lichen genus
The genus Marchantiana has been a victim of changeable concepts, partly due to erroneous DNA sequences published with its description. Based on new molecular sequencing, new chemical analyses and additional field work, mainly in Patagonia, Tasmania and New Zealand, we present a new taxonomic…

Circinaria tominii ( Megasporaceae , lichenized Ascomycota ) is represented by two different growth forms
Molecular study of Circinaria specimens collected in arid habitats of the Chuya Steppe showed the existence of two different growth forms, crustose and vagrant, in C. tominii that implies a more complex lifecycle of the species compared to that postulated by Mereschkowsky for vagrant taxa. An ITS…
