- We report here the draft de novo genome assembly, transcriptome assembly, and annotation of the lichen-forming fungus Arthonia radiata (Pers.) Ach., the type species for Arthoniomycetes, a class of lichen-forming, lichenicolous, and saprobic Ascomycota. The genome was assembled using overlapping paired-end and mate pair libraries and sequenced on an Illumina HiSeq 2500 instrument.

- With an increasing demand for forest-based products, there is a growing interest in introducing fast-growing non-native tree species in forest management. Such introductions often have unknown consequences for native forest biodiversity. In this study, we examine epiphytic lichen species richness and species composition on the trunks of non-native Pinus contorta and compare these to the native Pinus sylvestris and Picea abies in managed boreal forests in northern Sweden across a chronosequence of age classes. Overall, we recorded a total of 66,209 lichen occurrences belonging to 57 species in the 96 studied forest stands. We found no difference in species richness of lichens between stands of P. contorta and P. sylvestris, but stands of P. abies had higher total species richness. However, species richness of lichens in stands of P. abies decreased with increasing stand age, while no such age effect was detected for P. contorta and P. sylvestris. Lichen species composition progressively diverged with increasing stand age, and in 30-year-old stands all three tree species showed species-specific assemblages. Epiphytic lichen assemblages in stands of 30-year-old P. contorta were influenced by greater basal area, canopy closure, and average diameter at breast height, P. abies stands by higher branch density and canopy closure, and stands of P. sylvestris by greater bark crevice depth. Differences in lichen species richness and composition were mainly explained by canopy closure and habitat availability, and the greater canopy closure in mature P. abies stands promoted the colonization and growth of calicioid lichen species. Our results indicate that the non-native P. contorta have similar species richness as the native P. sylvestris. The main difference in lichen species richness and composition is between P. abies and Pinus spp. in managed forests of boreal Sweden.

Additions to the calicioid flora of Japan and Korea, with the descriptions of two new species

- Two new species of calicioid fungi are described, Phaeocalicium triseptatum Tibell and Sphinctrina intermedia Tibell. While P. triseptatum is only known from Hokkaido, Japan, S. intermedia is known from Hokkaido and Korea. Sphinctrina leucopoda as reported from Korea in the literature is misidentified S. intermedia. The genus Microcalicium is reported as new to Japan with one species, M. arenarium. Phaeocalicium flabelliforme is reported as new to Asia (Japan). Chaenothecopsis savonica is reported as new to Japan and Sphinctrina tubaeformis as new to Hokkaido.

Arthonia incarnata (Arthoniaceae), a rare and poorly known old-growth forest lichen new to Asia
- 2017
-
Ingår i: Nordic Journal of Botany. - : Wiley. - 0107-055X. ; 35, s. 587-594

Tidskriftsartikel (refereegranskat)abstract
- The rare and poorly known Northern Hemisphere old-growth forest lichen Arthonia incarnata is reported for the first time for Asia from Japan and Korea. A detailed description and illustration is provided for the species based on the collections from Japan and South Korea. Bayesian and RAxML analyses of mtSSU, nLSU and RPB2 sequence data show A. incarnata to be only distantly related to the other Arthonia species hitherto sequenced and in particular to superficially similar species occurring in the same type of habitat such as A. didyma, A. spadicea and A. vinosa. For the analysis we generated new sequence data of A. incarnata for the mtSSU (5 specimens) and RPB2 (5) gene loci. Slight variation was observed in sequence data of the RPB2 gene between collections from eastern Asia and Sweden, but this is not substantiated by differences in morphology or ecological behaviour. Arthonia incarnata is confined to humid forests and only grows on parts of tree trunks shaded from precipitation and running water such as the lower side of leaning trunks or cavities at the base of trees. The species is found on trees with acidic bark, in eastern Asia mainly on Betula but also on coniferous trees and on dead wood. It was not found on bark of Salix (caprea), a common substrate for the species in Europe.

Arthonia parietinaria - A common but frequently misunderstood lichenicolous fungus on species of the Xanthoria parietina-group

- Arthonia parietinaria is described as new to science. Host of the type and at the same time the only confirmed host species is the foliose macrolichen Xanthoria parietina. Sequence data of nucLSU rRNA genes reveal a close relationship to Arthonia molendoi. A. parietinaria is recorded for many countries in Europe, western Asia, and northern Africa.

- Arthonia sanguinaria is described as new to science. The East Asian Arthonia lopingensis and the widely distributed. Arthonia picea are reported as new to Japan from Honshu and the Ogasawara Islands, respectively. The phylogenetic position of A. picea, A. sanguinaria and Coniocarpon cinnabarinum from the Ogasawara Islands is shown by RAxML and Bayesian analysis of mtSSU, nLSU and RPB2 sequence data. Our results confirm the polyphyletic origin of quinoid pigments in Arthoniaceae. A key is presented to the Arthoniaceae with reddish ascomata in Japan.

- Crypthonia with 11 species is described as belonging to the Arthoniaceae. The new genus is characterised by (1) white to pale carneous, maculiform ascomata lacking a distinct exciple, (2) a weakly gelatinised, hydrophobic hymenium of paraphysoids, (3) a discontinuous layer of branched ascogenous hyphae in the hypothecium, (4) small, clavate to broadly clavate asci of the Arthonia-type lacking a hemiamyloid ring structure in the tholus, (5) eight small, hyaline, 1-3-septate, thin-walled ascospores per ascus, (6) loosely attached thalli with a byssoid, coloured hypothallus, and (7) a chemistry of mainly beta-orcinol depsidones and tridepsides including psoromic, norstictic, and gyrophoric acids. Rugulosin occurs in C. bella and C. citrina. Crypthonia athertoniensis Frisch & G. Thor, C. bella Frisch & G. Thor, C. brevispora Frisch & G. Thor, C. citrina Frisch & G. Thor, C. olivacea Frisch & G. Thor, C. palaeotropica Frisch & G. Thor, and C. vandenboomii Frisch & G. Thor are described. C. albida (F,e) Frisch & G. Thor, C. biseptata (Aptroot & Wolseley) Frisch & G. Thor, C. mycelioides (Vain.) Frisch & G. Thor, and C. polillensis (Vain.) Frisch & G. Thor are new combinations. The delimitation from similar genera and the position within the Arthoniaceae is discussed.

- Arthonia physcidiicola Frisch & G.Thor, Chiodecton sorediatum G.Thor & Frisch, Herpothallon kigeziense Frisch & G.Thor and Reichlingia syncesioides Frisch & G.Thor are described as new to science. All species have been collected in the montane rainforests of Bwindi Impenetrable National Park in south western Uganda. The earlier monotypic genus Reichlingia with one anamorphic species is emended to include three fertile species and is newly reported to Africa. The combinations Reichlingia virginea (Mull.Arg.) Frisch for Arthothelium virgineum Mull.Arg. from the Usambara Mts. in north eastern Tanzania, and Reichlingia zwackhii (Sandst.) Frisch & G.Thor for the European Arthonia zwackhii Sandst. are made. A phylogenetic tree based on Bayesian and ML analyses of combined mtSSU, nLSU and RPB2 data showing the position of the new species in Arthoniomycetes is presented.
