As part of a larger systematic and taxonomic revision, including molecular phylogenetic analysis, of lichenized Basidiomycota in the Dictyonema clade, ten species are described as new from tropical America, seven in the foliose genus Cora and three in the filamentous genus Dictyonema : Cora arachnoidea J. E. Hern. & Lucking, sp. nov. , C. aspera Wilk, Lucking & E. Morales, sp. nov. , C. byssoidea Lucking & Moncada, sp. nov. , C. cyphellifera Dal-Forno, Bungartz & Lucking, sp. nov. , C. inversa… 
Five new species of Cora and Dictyonema (Basidiomycota: Hygrophoraceae) from Colombia: chipping away at cataloging hundreds of unrecognized taxa
All new species of Cora fall into only one of the two major Cora clades and are not closely related to the morphologically most similar taxa.
New species of Dictyonema and Cyphellostereum (lichenized Basidiomycota: Hygrophoraceae) from tropical Africa and the Indian Ocean, dedicated to the late Hildur Krog
A small collection of lichenized fungi belonging in the Dictyonema clade from E Africa and Mauritius, tentatively identified as D. sericeum, revealed four species new to science, one in the genus Cyphellostereum and three in the grouping with shelf-like morphotypes, including the first species known to form a distinctly layered thallus.
Three new species of Dictyonema ( lichenized Basidiomycota : Hygrophoraceae ) from Bolivia Tres nuevas especies de Dictyonema ( Basidiomycota liquenizados : Hygrophoraceae ) de Bolivia
Three new species of Dictyonema are described from Bolivia, characterized by an appressed filamentous thallus in which the fibrils are completely horizontally oriented and partially embedded in a gelatinous matrix formed by the thick generative hyphae of the mycobiont.
From one to six: unrecognized species diversity in the genus Acantholichen (lichenized Basidiomycota: Hygrophoraceae)
A detailed morphological and anatomical study of recently collected specimens from the Galápagos, Costa Rica, Brazil and Colombia, combined with a molecular phylogenetic analysis of the internal transcribed spacer region and 28S of the nuc rDNA and RPB2 sequences, revealed a much more diverse and widespread species assemblage.
Two new, sympatric and semi-cryptic species of Sulzbacheromyces (Lichenized Basidiomycota, Lepidostromatales) from the Chocó Biogeographic Region in Colombia
The utility of DNA barcoding for delimiting species in lichenized Basidiomycota from Colombia is examined, focusing on the genus Sulzbacheromyces (Lepidostromatales), including the six already known species S. caatingae from Brazil, S. miomboensis De Kesel & Ertz from Africa, and S. yunnanensis from Asia.
A new species of Hygrophorus, H. yadigarii sp. nov. (Hygrophoraceae), with an isolated systematic position within the genus from the Colchic part of Turkey
Hygrophorus yadigarii (Hygrophoraceae/Basidiomycota) is described as a new species for science based on basidiomata collected from Macka, Trabzon, Turkey. The new taxon is quite different even from
Two new genera and twelve new species of Graphidaceae from Puerto Rico: a case for higher endemism of lichenized fungi in islands of the Caribbean?
It is highly likely that at least some of these new taxa are endemic to the island, and further supported by the unique features of several of the new species, representing novel characters in the corresponding genera.
Cyphellostereum ushimanum sp. nov. (Hygrophoraceae, Agaricales) described from Amami-Oshima Island (Kagoshima Prefecture, Ryukyu Islands), Japan, with ultrastructural observations of its Rhizonema photobiont filaments penetrated longitudinally by a central haustorium
A resupinate fungus lichenized with filamentous Rhizonema cyanobacteria in Amami-Oshima Island, Japan is collected and its unique combination of structural characters and ITS rDNA sequences suggests a new species, described here as C. ushimanum.
Turbo-taxonomy to assemble a megadiverse lichen genus: seventy new species of Cora (Basidiomycota: Agaricales: Hygrophoraceae), honouring David Leslie Hawksworth’s seventieth birthday
Based on an updated phylogeny using the ITS fungal barcoding locus, Cora is now recognize 189 taxa in a genus that until recently was considered to represent a single species; including this contribution, 92 of these are formally recognized, including five taxa based on historical names or collections that have not been sequenced.

One hundred new species of lichenized fungi : a signature of undiscovered global diversity
A total of 100 new species of lichenized fungi are described, representing a wide taxonomic and geographic range, and emphasizing the dire need for taxonomic expertise in lichenology.
Lepidostromatales, a new order of lichenized fungi (Basidiomycota, Agaricomycetes), with two new genera, Ertzia and Sulzbacheromyces, and one new species, Lepidostroma winklerianum
The photobionts of Sulzbacheromyces and Lepidostroma were identified using molecular data of the large subunit of the ribulose 1,5-bisphosphate carboxylase/oxygenase (rbcL) gene, revealing a possibly undescribed genus in Trebouxiophyceae and the first report of lichenization for the genus Bracteacoccus in ChlorophyCEae.
Dictyonema coppinsii, a new name for the European species known as Dictyonema interruptum (Basidiomycota: Agaricales: Hygrophoraceae), with a validation of its photobiont Rhizonema (Cyanoprokaryota: Nostocales: Rhizonemataceae)
A new name is established, Dictyonema coppinsii Lücking, Barrie & Genney, for the lichenized fungus at hand, whereas the cyanobacterial photobiont is validated with the genus name Rhizonema Lücker & Barrie, adopting the epithet interruptum for it, and placed in a separate family.
High concentration of basidiolichens in a single family of agaricoid mushrooms (Basidiomycota: Agaricales: Hygrophoraceae).
A first assessment of Galapagos basidiolichens
A first assessment of the morphology and anatomy of basidiolichens from the archipelago is presented here and is the basis for further studies of the taxonomy, ecology and biogeography of this poorly known group of lichens.
A First Assessment of the Ticolichen Biodiversity Inventory in Costa Rica: The Genus Dictyonema (Polyporales: Atheliaceae)
It is suggested that foliose and crustose growth forms, although having similar thallus anatomy, do represent distinct taxa, but since molecular data to test this hypothesis are missing for this genus, for the time being these morphotypes at the level of forma are followed.

Results of a survey of nitrogen-fixing blue-green algal epiand endophytes growing in the cloud-shroud climate on the tropical volcano La Soufriere (Guadeloupe, French West Indies) are reported, finding stunted vegetation in the Lesser Antilles is stunted, and the climate is wetter and colder than at lower elevations.
