The class Eurotiomycetes (Ascomycota, Pezizomycotina) comprises important fungi used for medical, agricultural, industrial and scientific purposes. Eurotiomycetes is a morphologically and ecologically diverse monophyletic group. Within the Eurotiomycetes, different ascoma morphologies are found including cleistothecia and perithecia but also apothecia or stromatic forms. Mazaediate representatives (with a distinct structure in which loose masses of ascospores accumulate to be passively disseminated) … Read more... 

The new fruticose lichen species Trapeliopsis studerae with fruticose growth form, branches mostly flat to partly curling up, but lower down often almost cylindrical, much irregularly branched, 0.1– 0.2 mm thick and 0.3–0.6 mm wide, upper surface olive grey, pycnidia that probably belong to the lichen are present on some older parts of the thallus, superficial, brown, conical to somewhat inflated, conidia hyaline, clavate, 8–1131.5–2.5 lm, and chemistry gyrophoric acid, is described from … Read more... 

Lichenostigma saxicola, growing on silicate rocks and lichens, is described from southern California from both the Sonoran and Mojave deserts as well as from the Santa Monica Mountains on the coast. The species belongs to the subgenus Lichenostigma, has a non-amyloid centrum, and dark one-septate ascospores, 10–12 3 5–6 mm, cells equal or not, constricted at the septum, the walls of over-mature ascospores becoming granular-verrucose. The species is considered facultatively lichenicolous, not … Read more... 

This paper presents a new lichenometric dating curve for southeast Iceland. The temporal framework for the curve is based on reliably dated surfaces covering the last 270 years, making it the best constrained study of this nature conducted in Iceland. The growth of lichen species within Rhizocarpon Section Rhizocarpon is non-linear over time, with larger (older) thalli apparently growing more slowly. The linear 'growth' curves derived previously by former authors working in Iceland represent … Read more... 

Lecanora baekdudaeganensis Lee & Hur is described as a new lichenized fungus from Baekdudaegan Mountains, South Korea. The new species is classified into the Lecanora subfusca group – allophana type and distinguishable from Lecanora imshaugii Brodo by a darker thallus, brownish disc, K–insoluble granules on the surface of the epihymenium, shorter hypothecium, and the presence of oil droplets in the apothecial section. Molecular analyses employing internal transcribed spacer (ITS) and mitochondrial small … Read more...
