The new sorediate species Lecanora kenyana from Mount Kenya and L. orientoafricana from the Rift Valley in Kenya are described. L. kenyana has red-brown apothecia with a constricted base, a melacarpella–type amphithecium, pulicaris–type epihymenium, a hyaline hypothecium, and contains usnic acid as major constituent. L. orientoafricana is characterized by having a dark hypothecium, pulicaris-type amphithecium, chlarotera-epihymenium, and contains atranorin and gangaleoidin. A phylogenetic…

Molecular and phenotypical studies on species diversity of Hypotrachyna (Parmeliaceae, Ascomycota) in Kenya, East Africa
TLDR
The hypothesis that distributional ranges in parmelioid lichens are more restricted than previously assumed is supported, which supports the idea that several species that were supposed to have wide, intercontinental distributions consist of separate lineages.
Molecular phylogeny of placodioid lichen-forming fungi reveal a new genus, Sedelnikovaea
A molecular phylogeny based on ITS1/ITS2 and mtSSU DNA sequences is presented for lichen-forming fungi in Protoparmeliopsis and its distant relative Sedelnikovaea gen. nov. The positions of the two
The circumscription and phylogenetic position of Bryonora (Lecanoraceae, Ascomycota), with two additions to the genus
TLDR
The phylogenetic position of the genus Bryonora and its segregate Bryodina is assessed for the first time, using a six-locus phylogeny comprising the Lecanoraceae as well as closely related families.
Lecanora markjohnstonii (Lecanoraceae, lichenized Ascomycetes), a new sorediate crustose lichen from the southeastern United States
TLDR
A fully assembled and annotated mitochondrial genome was compared to other lichenized fungal mitogenomes, including the publicly available Lecanora strobilina mitogenome, and showed that the gene region atp9 was missing as in other members of the Lecansorales.
Turnover of Lecanoroid Mycobionts and Their Trebouxia Photobionts Along an Elevation Gradient in Bolivia Highlights the Role of Environment in Structuring the Lichen Symbiosis
TLDR
A phylogenetically defined sampling of a single diverse family of lichen-forming fungi may be sufficient to document regional patterns of Trebouxia diversity and distribution.
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
Evidence of substrate endemism of lichens on Fox Hills Sandstone: Discovery and description of Lecanora lendemeri as new to science
TLDR
Using IUCN criteria including a known occurrence of only three populations, the largest of which is under conservation threat, this new species is formally ranked as Endangered.
DIVERSITY, ECOLOGY AND ALTITUDINAL DISTRIBUTION OF CORTICOLOUS LICHENS IN MOUNT KENYA TROPICAL MONTANE FOREST
While recent studies indicate a high diversity of lichens in the tropical regions of the world equaling or even surpassing that of temperate areas, studies of lichens in these regions remain rare and

A taxonomic survey of Lecanora sensu stricto in Thailand (Lecanoraceae; Ascomycota)
TLDR
The species of Lecanora sensu stricto occurring in Thailand are revised with one new species, L. kansriae described for a taxon with small crystals in the amphithecium and containing the stictic acid chemosyndrome.
A new species and new records of Lecanora (Lecanoraceae, Ascomycota) from south–east Asia
TLDR
The new species Lecanora ulrikii from Bhutan and Thailand is described, characterized by relatively large, orange-brown to brown apothecia that are constricted at the base, a clear to inspersed hymenium, an epihymenium of the glabrata-type, and by the presence of atranorin, usnic acid and the isoarthothelin chemosyndrome.
New Species and New Records of Lecanora s.str. from Western North America
TLDR
Four previously described species are recorded for the first time from North America as new to science and two apparently undescribed species belonging to the L. subfusca group are described below.
A Revision of the Usnic Acid Containing Taxa Belonging to Lecanora sensu stricto (Lecanorales: Lichenized Ascomycotina)
TLDR
It is concluded that the usnic acid containing species of Lecanora do not form a natural group and cannot be separated from the group.
A New Species in the Lecanora Subfusca Group Containing Usnic Acid in Addition to Atranorin
New or Overlooked Species in the Lecanora subfusca Group from Southwestern North America (Lecanorales, Ascomycotina)
TLDR
These overlooked species are new to the U.S.A. and provide clues to the distribution and habits of these overlooked species, which have been overlooked for decades.
Molecular Systematics of Lecanora Subgenus Placodium
TLDR
A congruence between molecular data and secondary chemistry supports the broader concept of the L. dispersa group suggested by the molecular data, which is not monophyletic.
Is Rhizoplaca (Lecanorales, lichenized Ascomycota) a monophyletic genus?
TLDR
The results suggest an origin for Rhizoplaca species within the large genus Lecanora, and show that the umbilicate thallus with a lower and an upper cortex, as well as apothecia with a cupulate hypothecium found in Rhzoplaca and A. thuleana, have developed several times in independant lineages in LECanora.
A phylogenetic study of the Lecanora rupicola group (Lecanoraceae, Ascomycota).
TLDR
The results suggest the monophyly of the Lecanora species that are characterized by the presence of chromones, which are not closely related to the L Cecanora rupicola group.
New Records of Lichen-Forming Fungi from Kenya
TLDR
The lichen diversity in the Mount Kenya montane forests was very rich with fifty-nine species recorded for the first time from Kenya; 18 of them are new records for the African continent.
