Abstract The crustose lichen genus Mycoblastus in the Northern Hemisphere includes eight recognized species sharing large, simple ascospores produced 1–2 per ascus in strongly pigmented biatorine apothecia. The monophyly of Mycoblastus and the relationship of its various species to Tephromelataceae have never been studied in detail. Data from ITS rDNA and the genes coding for translation elongation factor 1-α and DNA replication licensing factor mini-chromosome maintenance complex 7 support the… 
Molecular phylogenetics and taxonomy of the Calvitimela aglaea complex (Tephromelataceae, Lecanorales)
TLDR
The molecular results further support the recognition of two recently discovered sterile crusts as new species, Calvitimela cuprea and C. livida, distinguished from previously known species by their production of asexual diaspores and from each other by secondary metabolite chemistry.
Palicella, a new genus of lichenized fungi and its phylogenetic position within Lecanoraceae
Abstract Non-saxicolous lecideoid lichens form a diverse and polyphyletic group of species with a worldwide distribution. The phylogenetic relationships of the taxa and major clades are still largely
Phylogenetic Data and Chemical Traits Characterize a New Species in the Lichen Genus Tephromela
TLDR
Improved morphological and molecular analyses are provided to understand the diversity of corticolous taxa and support the recognition of a new species in the lichen genus Tephromela, confirming the presence of anew monophyletic lineage.
Phylogenetic relationships within Pyrenodesmia sensu lato and the role of pigments in its taxonomic interpretation
TLDR
Within Pyrenodesmia sensu lato, three lineages were revealed and recognized on a generic level and the identity of Kuettlingeria (Caloplaca) diphyodes was clarified and the name Pyrenodemia helygeoides was resurrected.
DISCOMYCETES: the apothecial representatives of the phylum Ascomycota
TLDR
A historical perspective of discomycetes is provided, notes on their morphology (including both asexual and sexual morphs), ecology and importance, an outline of disComycete families and a synoptical cladogram of currently accepted families in AscomyCota showing their systematic position are provided.
Phylogeny and taxonomy ofPolyozosia, SedelnikovaeaandVerseghyaof the Lecanoraceae (Lecanorales, lichen-forming Ascomycota)
From the combined phylogenetic analysis of multi-locus sequence data of the Lecanoraceae including two nuclear protein-coding markers (RPB2 and RPB1), the internal transcribed spacer and a fragment
Three new lichen species from Nicaragua, with keys to the known species of Eugeniella and Malmidea
TLDR
Eugeniella palleola, Graphis paraschiffneri, and Malmidea cineracea are described from Nicaragua, characterized by having pale apothecial discs and prominent, white margins, and producing a complex chemistry including atranorin, stictic and norstictic acids, and an unknown substance.
Observations on the genus Tephromela (lichenised Ascomycetes) in Tasmania, with the Description of a New Species
TLDR
Five species of Tephromela are recognised for Tasmania: T. granularis, described as new; T. campestricola (Nyl.) Rambold & Triebel, lichenicolous on Lecanora spp.
Notes for genera: Ascomycota
TLDR
This work is intended to provide the foundation for updating the ascomycete component of the “Without prejudice list of generic names of Fungi” published in 2013, which will be developed into a list of protected generic names.
New records and a key to the species of Malmidea (lichenized Ascomycota) from India
TLDR
During the examinations of the specimens earlier identified as Lecidea granifera deposited in the herbarium LWG and fresh collections from Goa, the authors came across with some interesting specimens which resulted in six new records for India.

Genetic diversity and photobiont associations in selected taxa of the Tephromela atra group (Lecanorales, lichenised Ascomycota)
TLDR
Phylogenetic analysis of photobionts ITS sequences revealed that thalli from the Mediterranean region are associated with two distinct lineages of Trebouxia, but the lineages are not correlated with substrate or mycobiont phenotype, suggesting a protracted isolation from the other lineages.
New insights into classification and evolution of the Lecanoromycetes (Pezizomycotina, Ascomycota) from phylogenetic analyses of three ribosomal RNA- and two protein-coding genes.
TLDR
The phylogenies confirm that ascus morphology cannot be applied consistently to shape the classification of lichen-forming fungi and conclude that a phylogenetic synthesis for a chosen taxonomic group should include a comprehensive assessment of phylogenetic confidence based on multiple estimates using different methods and on a progressive taxon sampling with an increasing number of taxa, even if it involves an increasing amount of missing data.
The sister group relation of parmeliaceae (Lecanorales, Ascomycota).
TLDR
The aim of the present study is to contribute to finding the sister group of Parmeliaceae as an aid in future studies on the phylogeny and character evolution of the group.
New or Interesting British Lichens: 1
TLDR
The Lecidea granulosa group is referred to Trapeliopsis, necessitating four new combinations, T. aeneofusca (Florke ex Flotow), T. flexuosa (Fr.) comb, nov., T. gelatinosa ( Florke) comb.
The genus Mycoblastus in the cool temperate Southern Hemisphere, with special reference to Tasmania
TLDR
It is suggested that the genus Mycoblastus is heterogeneous and that some of its closest affinities may lie with the family Megalariaceae and the genus Japewia.
The limitations of ancestral state reconstruction and the evolution of the ascus in the Lecanorales (lichenized Ascomycota).
TLDR
This investigation explored the outcomes of a variety of methods for reconstructing discrete ancestral state in the ascus apex of the Lecanorales, a group containing the majority of lichen-forming ascomycetes, and designed a novel method for assessing the suitable number of discrete gamma categories which relies on the effect on phylogeny estimates rather than on likelihoods.

TLDR
The new species Calvitimela austrochilenis Fryday and Tephromela superba Fryday are described: the former from several collections from southern Chile and one from Marion Island, and the latter from southern South America, Campbell Island, New Zealand, and Antarctica.
