Jamesiella scotica new to North America from USA, Alaska

Jamesiella scotica is reported new to North America from Kenai Fjords National Park in Alaska. It was found on live and moribund leaves of the bryophyte Paraleucobryum longifolium on sea-shore rocks just above high tide line.

Lepraria lobificans (syn. L. santosii) and L. sylvicola new to northern Europe from Norway

The two lichen species Lepraria lobificans (syn. L. santosii) and L. sylvicola are reported new to northern Europa, based on collections from Western Norway and Northern Norway, respectively. The specimens were identified by morphology, thin-layer chromatography, and the DNA barcode marker. The common species currently named L. lobificans in Northern Europe should be named L. finkii.publishedVersio

A new species of Sagiolechia (Sagiolechiaceae) from Norway, with lirelliform ascomata and 1-septate ascospores

The new species Sagiolechia monoseptata is described from the northern boreal zone of Norway where it was found on a shaded siliceous rock under a boulder in a north-facing, small, steep scree. It is characterized by the pale greyish-green thallus, black, lirelliform ascomata, and 1-septate ascospores of (11–) 12–16 × (4–) 5–6 (– 7) µm, all features unique within the genus. Despite the unusual combination of morphological characters, phylogenetic analyses using nuLSU, mtSSU and RPB2 sequences place the new lichen in the genus Sagiolechia with full support.publishedVersio

Marchantiana asserigena, a genus and species new to Norway

Marchantiana asserigena is reported new to Norway from the south-west (counties Rogaland, Hordaland, Sogn og Fjordane, and Møre og Romsdal) at altitudes from near sea level to 393 m. It occurs on branches of trees and shrubs and has been found on 33 species of phorophytes (including two hybridigenous ones). Larix decidua was the phorophyte with most collections. Based on the present material M. asserigena seems to be widespread in urban and suburban areas and in the cultural landscape. It is likely that M. asserigena is more widely distributed in Norway than the presented material indicates. Due to the inconspicuous thallus, the diminutive apothecia, and its unusual ecology it is easily overlooked.publishedVersio

The Sticta fuliginosa group in Norway and Sweden

A recent investigation demonstrated that Sticta fuliginosa (Hoffm.) Ach., as currently treated, includes four distinct species in Europe: Sticta fuliginosa s. str., S. fuliginoides Magain & Sérus., S. ciliata Tayl., and S. atlantica Magain & Sérus. This finding prompted us to revise material named S. fuliginosa from Norway and Sweden. It is demonstrated here that three species occur in Norway: S. fuliginosa s. str., S. fuliginoides, and S. ciliata. S. fuliginoides is the most widespread species, whereas S. fuliginosa occurs mostly along the coast and S. ciliata is very rare in the most oceanic parts of the western coast. In Sweden, only a single species of the group occurs, viz. S. fuliginoides. It was formerly found in scattered sites across the southern half of Sweden but has now disappeared from most of them. The basionym Sticta fuliginosa var. propagulifera Vain. ex H. Magn. is lectotypified and synonymized under S. fuliginoides.publishedVersio

The taxonomy of the lichen Fuscidea cyathoides (Fuscideaceae, Umbilicariomycetidae, Ascomycota) in Europe

Based on morphometric and molecular methods, the taxonomy of the infraspecific taxa of Fuscidea cyathoides (Ach.) V. Wirth & Vězda, var. corticola (Fr.) Kalb and var. sorediata (H. Magn.) Poelt, has been assessed. No formal taxonomic recognition should be attributed to the morphological and ecological variation. Accordingly, var. corticola and var. sorediata are synonymized with F. cyathoides var. cyathoides. New synonyms at the specific level are Fuscidea fagicola (Zschacke) Hafellner & Türk and F. stiriaca (A. Massal.) Hafellner.acceptedVersio

Three overlooked species of Bacidia from insular Laurimacaronesia

We discuss the taxonomy of three species of Bacidia occurring in insular Laurimacaronesia. Two of them, B. amylothelia (Vain.) Vain. and B. endoleucoides (Nyl.) Zahlbr., which were previously described from Angola and Madeira, respectively, are found here to belong in Bacidia s. str. (Ramalinaceae). Modern descriptions and illustrations are provided for the first time. Bacidia amylothelia is similar to B. areolata Gerasimova & A. Beck, B. campalea (Tuck.) S. Ekman & Kalb, B. fusconigrescens (Nyl.) Zahlbr., B. heteroloma (Vain.) Zahlbr., B. millegrana (Taylor) Zahlbr. and B. suffusa (Fr.) A. Schneid. and is reported here from the Canary Islands. Bacidia endoleucoides is most likely to be confused with B. absistens (Nyl.) Arnold, B. friesiana (Hepp) Körb., B. salazarensis B. de Lesd. and B. caesiovirens S. Ekman & Holien and was found to be widely distributed in the Canary Islands and Azores in addition to Madeira. The third species, Bacidia deludens S. Ekman, Tønsberg & van den Boom, is described here as new to science. Bacidia deludens is characterised by a greyish, crustose thallus with whitish soralia, pale apothecia with crystals in the hymenium and proper exciple, acicular ascospores with 3–19 septa, and the production of fumarprotocetraric acid as the consistently present major substance. It is described here from the Canary Islands and Madeira. Although conservatively treated here in Bacidia, we argue that it is likely to belong in the Malmideaceae. An identification key to all known species of Bacidia s. str. in insular Macaronesia is provided.publishedVersio

A new corticolous species of Rinodina (Physciaceae) and two interesting range extensions for species collected from Katmai National Park, Alaska

Rinodina pallidescens is described as a new species, endemic to southern Alaska. Rinodina buckii and R. oregana are discussed in terms of their range extensions and possible phytogeographic histories.This is an author's peer-reviewed final manuscript, as accepted by the publisher.

New and noteworthy lichens and lichenicolous fungi from Norway

Twelve species of lichens and lichenicolous fungi are reported as new to Fennoscandia. Additionally, we report 19 species as new to Norway. New localites are given for 47 rare or seldom collected species. The new combination Reichlingia anombrophila (Coppins & P. James) Frisch is proposed. Most collections were made in the boreo-nemoral and boreal rainforests during the NBIC funded project Three storied diversity – mapping and barcoding crustose lichens and lichenicolous fungi in the Norwegian rainforests and associated fieldwork in recent years. With the present contribution, we hope to raise awareness on previously neglected groups of lichenised and lichenicolous fungi and encourage further fieldwork in understudied habitats in Norway.publishedVersio
