The Buellia s. lat. species that occur in the Canary Islands are described including the related genera Amandinea, Diplotomma and Tetramelas. Species of the genera Coscinocladium, Dimelaena and Diploicia are also included. Forty-one species have been identified. Nine species are new records for the archipelago. The study of the type specimens and additional material of Buellia caloplacivora, B. sequax and B. leptina demonstrated that the two former are not conspecific and that the third is a valid taxon. The new combinations Buellia gomerana and Buellia alisioae are proposed. A short description, including the chemistry, ecology and distribution of all taxa is provided. A key to the species known to occur in the study area is also included. © 2011 J. Cramer in Gebr. Borntraeger Verlagsbuchhandlung, Stuttgart, Germany. Source


One hundred lichen species and lichenicolous fungi are reported from the Azores, occurring on São Miguel and/or Terceira, collected in 2011 and 2014. Thirty-seven species are newly recorded to the Azores and seven are described as new to science: Byssoloma fuscum, Lecania azorica, Sphaerellothecium heterodermiae, S. parmotremae, Stigmidium micareae, S. subcladoniicola, Thelocarpon microsporum. © 2016 Akadémiai Kiadó, Budapest.

Based on two field trips undertaken in 2009 as well as a review of the literature, a checklist of the lichens and the lichenicolous fungi from El Hierro, the most southwestern of the Canary Islands, is presented. As a result, a total of 589 taxa are reported, including 278 new for the island of which 57 are new for the Canary Islands. In addition, 5 species are newly described in the genera Lecania, Lecidea, Protoparmelia, Solenopsora and Trinathotrema. The number of novelties reported here indicates that El Hierro is exceedingly under-recorded for the lichens and the lichenicolous fungi. Terricolous, saxicolous, as well as corticolous species are recorded, but foliicolous lichens have not been found. Notes are given on ecology and sometimes on morphology and chemistry. © 2012 Adac.

Fungal Diversity | Year: 2012

Morphological, anatomical, chemical and molecular data suggest that a relatively common lichenicolous coelomycete on Lecanora conizaeoides is conspecific with Phoma cytospora, previously known only from parmelioid lichens, and that further populations on Cladonia and Pertusaria belong to the same species. This species is distinguished from Phoma by several taxonomically important characters and obviously represents a previously unrecognized genus, for which the name Briancoppinsia is introduced. Phylogenetic analyses using nuLSU and mtSSU sequences of isolates obtained in pure culture suggest that the new genus belongs to the Arthoniaceae (Arthoniales). This is the first obligate lichenicolous, non-lichenized anamorph confirmed to belong to the Arthoniales based on molecular data. © Kevin D. Hyde 2011. Source

A new lichen species, Waynea giraltiae van den Boom, is described from southern Portugal and Spain. It is characterized by a very fine tomentum on the squamulose thallus, fusiform, 3-septate ascospores, and strongly curved filiform conidia. It is the first species of the genus containing argopsin. The new species is compared with related Waynea species. Waynea cretica is recorded as new to the Iberian Peninsula. © 2009 British Lichen Society. Source
