Ach. Revisited.

Calicioids form a research field that has encompassed ascomycetous fungi with stalked ascomata similar to those of the lichen genus . Early generic circumscriptions of calicioid lichens and fungi were mainly based on morphological and secondary chemistry information. After the introduction of molecular data, taxonomy in the group has been reconsidered.

Marine fungi of the Baltic Sea.

Vast parts of the Baltic Sea have been mycologically neglected and are still awaiting exploration. Here we summarise earlier records of marine fungi from the Baltic, supplementing them with discoveries from fieldwork in Sweden in 2019. Although marine fungal diversity is clearly attenuated in the brackish water of the Baltic Sea, a substantial number has still been discovered.

Crustose Calicioid Lichens and Fungi in Mountain Cloud Forests of Tanzania.

A total of 26 crustose calicioid lichens and fungi were found in Tanzania. Most of them belong to a group of species with wide distributions in cool areas of both hemispheres and occasional occurrence in high mountains at low latitudes. In Tanzania calicioids mainly occur in the middle and upper forest zones and their niches are found on the bark of old trees and on lignum, most of them restricted to mountain cloud forests.

Phylogeny of the subgenus in Tanzania.

Several species in subgenus (, lichenized Ascomycota) have been described from East Africa in the past decades. These have been based on morphology and chemistry data while molecular studies remain very limited. In this paper we are for the first time publishing phylogenetic analyses along with morphological and chemical data for .

A worldwide phylogeography of the whiteworm lichens reveals three lineages with distinct habitats and evolutionary histories.

is a lichenized fungus with an extremely wide distribution, being encountered in arctic and alpine environments in most continents. In this study, we used molecular markers to investigate the population structure of the fungal symbiont and the associated photosynthetic partner of . By analyzing molecular, morphological, and chemical variation among 253 specimens covering the species distribution range, we revealed the existence of three mycobiont lineages.

Afrocantharellus gen. stat. nov. is part of a rich diversity of African Cantharellaceae.

A new genus in the Cantharellaceae, Afrocantharellus, is recognized based on results from phylogenetic analyses of rDNA LSU and concatenated LSU/5.8-ITS2/ATP6 data. It was previously recognized as a subgenus, but comprehensive fieldwork and the acquisition of numerous sequences for previously neglected African Cantharellus species formed the basis for a reappraisal of generic and species delimitations.

Racoleus, a new genus of sterile filamentous lichen-forming fungi from the tropics, with observations on the nomenclature and typification of Cystocoleus and Racodium.

Racoleus trichophorus gen. sp. nov.

Phylogeny and taxonomy of Aspicilia and Megasporaceae.

Phylogenetic analyses based on nuLSU and mtSSU indicate that Megasporaceae is monophyletic. Aspicilia species were distributed among three main well supported groups and one group with low support that included the type species; a division of the family into five genera is proposed. The old names Circinaria and Sagedia are reintroduced for groups not including A.

Molecular phylogeny and systematics of Polyblastia (Verrucariaceae, Eurotiomycetes) and allied genera.

Phylogenetic relationships of the lichen genus Polyblastia and closely related taxa in the family Verrucariaceae (Verrucariales, Chaetothyriomycetidae) were studied. A total of 130 sets of sequences (nuLSU rDNA, nuITS rDNA and RPB1 region A-D), including 129 newly generated sequences, were analysed. Phylogenetic relationships were inferred using a Bayesian approach based on two datasets.

A higher-level phylogenetic classification of the Fungi.

A comprehensive phylogenetic classification of the kingdom Fungi is proposed, with reference to recent molecular phylogenetic analyses, and with input from diverse members of the fungal taxonomic community. The classification includes 195 taxa, down to the level of order, of which 16 are described or validated here: Dikarya subkingdom nov.; Chytridiomycota, Neocallimastigomycota phyla nov.

Molecular phylogeny of the genus Lecania (Ramalinaceae, lichenized Ascomycota).

The molecular phylogeny of the lichen genus Lecania was investigated using nucleotide sequences from the mt-SSU rRNA, the ITS region of the nu-rDNA, and the RNA polymerase II second largest subunit. Forty-six species representing Lecania and other genera likely to influence the phylogeny were included in the study. Phylogenetic reconstructions were carried out using Bayesian inference, ML, and MP approaches.

Eurotiomycetes: Eurotiomycetidae and Chaetothyriomycetidae.

The class Eurotiomycetes (Ascomycota, Pezizomycotina) is a monophyletic group comprising two major clades of very different ascomycetous fungi: (i) the subclass Eurotiomycetidae, a clade that contains most of the fungi previously recognized as Plectomycetes because of their mostly enclosed ascomata and prototunicate asci; and (ii) the subclass Chaetothyriomycetidae, a group of fungi that produce ascomata with an opening reminiscent of those produced by Dothideomycetes or Sordariomycetes. In this paper we use phylogenetic analyses based on data available from the Assembling the Fungal Tree of Life project (AFTOL), in addition to sequences in GenBank, to outline this important group of fungi. The Eurotiomycetidae include producers of toxic and useful secondary metabolites, fermentation agents used to make food products and enzymes, xerophiles and psychrophiles, and the important genetics model Aspergillus nidulans.

Species recognition in the truffle genus Tuber -- the synonyms Tuber aestivum and Tuber uncinatum.

The two morphologically similar truffles Tuber aestivum and T. uncinatum have caused confusion because T. uncinatum is regarded by different authors, as either a distinct species, variety, subspecies, or synonym of T.

Tholurna dissimilis and generic delimitations in Caliciaceae inferred from nuclear ITS and LSU rDNA phylogenies (Lecanorales, lichenized ascomycetes).

The phylogenetic relationships of Tholurna dissimilis were investigated in relation to a phylogeny of twenty-three species in Caliciaceae and eighteen species from Physciaceae. ITS and LSU regions of the nuclear ribosomal DNA were used for the reconstruction of phylogenies by maximum parsimony methods. Calicium adaequatum was shown to be the closest relative of and possibly congeneric with Tholurna.
