We document the presence of Schistidium marginale (Grimmiaceae) in Trollheimen, central Norway. The sequence of the nuclear ITS region aligns identically with an accession from the Caucasus, distinct from Alpine accessions. This may suggest post-glacial colonization originating from south-eastern rather than southern populations. The new locality exhibited only a few tufts and shared habitat similarities with Alpine locations, albeit with a potentially more base-rich substrate.

The study presents all available information for epiphytic lichens and allied fungi on Pinus heldreichii and P. peuce in Bulgaria. The trees are respectively, subendemic and endemic for the Balkan Peninsula. Comments on distribution and diversity of species are provided. A total of 78 species are reported. Two lichen species are reported for the first time from Bulgaria, Blastenia monticola and Hypogymnia laminisorediata. Lecanora cadubriae is confirmed from Bulgaria. The following species are reported for the first time for the Pirin Mountains: Cladonia glauca, Lepraria elobata, Melanelixia glabratula, Micarea prasina, Nephromopsis chlorophylla, Strangospora moriformis, while Lichenoconium erodens is new for the Vitosha region and L. lecanorae for the Rila Mountains.

In the present paper four new records of lichenicolous species of Arthonia Ach. are reported from India. Arthonia aspiciliae is growing on the thallus and ascomata of Aspicilia sp., Arthonia destruens on the thallus of Physcia stellaris, Arthonia hawksworthii on the thallus of Dimelaena sp. and Arthonia protoparmeliopseos on the thallus and apothecial discs of Protoparmeliopsis muralis. Brief descriptions, illustrations, distributions, hosts and an artificial key to all known lichenicolous species of Arthonia from India is also provided.

This is a revision of the completely limbate African Fissidens species with small. to medium sized, pluripapillose and mammillose laminal cells. These species belong to subg. Polypodiopsis Müll. Hal.) Broth. (formerly known as subg. Aloma (Kindb.) Pursell & Brugg.-Nann.) sect. Antennidens (Müll. Hal.) Paris (formerly known as sect. Semilimbidium Müll. Hal.). One new species, viz. F. latelimbatus Brugg.-Nann. sp. nov. is described here. Furthermore, a number of new synonyms is proposed. Thus, F. dupuisii Renauld & Cardot, F. dicranelloides Paris & Broth. in Paris, F. occultifolius Müll. Hal. ex Paris, F. circinicaulis Cardot, F. tisserantii Broth. & P. de la Varde in P. de la Varde, F. rugifolius Dixon, F. glauculus var. aculeifrons P. de la Varde in Thér. and F. undatus (Müll. Hal.) Par. are subsumed under F. dasyphus Welw. & Duby in Duby, while F. glaucissimus var. minor Welw. & Duby in Duby is subsumed under F. glaucissimus Welw. & Duby in Duby var. glaucissimus and F. glauculus var. gymnandrus P. de la Varde under F. unipapillosus Brugg.-Nann.. All species are provided with a newly confirmed geographic distribution. Country records not confirmed by me are provided with a reference. This paper further includes several new country records: Fissidens dasyphus is reported new to Sudan, Madagascar and Malawi, F. glaucissimus Welw. & Duby to Burundi, F. inaequalilimbatus Paris & Broth. to the Democratic Republic of the Congo, F. unipapillosus Brugg.-Nann. to Gabon and F. biformis Mitt. to Guinea. The following taxa are lectotypified: Fissidens dicranelloides Paris & Broth., F. dupuisii Renauld & Cardot, F. glaucissimus Welw. & Duby, F. glauculus var. aculeifrons P. de la Varde, F. g. var. gymnandrus P. de la Varde, F. inaequalilimbatus Paris & Broth., F. microphoenix P. de la Varde, F. occultifolius Müll. Hal. ex Paris (= Fissidens muelleri Dusén, hom. illeg.), F. rugifolius Dixon, F. subglaucissimus Broth., F. thallangae Dixon and F. tisserantii Broth. & P. de la Varde.

A study of the variable species Oxyrrhynchium hians s.l. in NW Europe based on nuclear ITS, and plastid rpl16 and trnLtrnF, as well as morphology, revealed unsuspected species level diversity. Three taxa are distinguishable by morphology: O. distichum with complanate or sub-complanate branch leaves and long and narrow leaf lamina cells, O. hians with cordate or broadly ovate, concave leaves that are evenly arranged around the stems and branches, and O. swartzii with mostly complanate or sub-complanate branch leaves and compared with O. distichum relatively short and wide leaf lamina cells. In Sweden O. distichum grows almost exclusively on base-rich or calcareous rocks and has been recorded from a belt stretching from the Baltic Sea islands of Öland and Gotland to Dalarna and southernmost Norway, whereas the other two species grow on various substrates and have wider distributions. Oxyrrhynchium hians grows in more nutrient-rich habitats than O. swartzii and is therefore absent from regions with relatively poor soils. Oxyrrhynchium swartzii occurs northwards to Sør-Trøndelag in Norway and Jämtland and Medelpad in Sweden and includes two semi-cryptic species that differ slightly in size and may have relatively more western and eastern distributions, respectively, in Fennoscandia.

Recent finds of lichenicolous fungi from the Netherlands are described and discussed. Echinothecium micareae spec. nov. and Lichenochora verrucariae spec. nov. are described as new for science.

The name Andreaea vilocensis Broth. (Andreaeaceae, Bryophyta) from Bolivia is lectotypified. Description is provided along with figures.

Cladonia furfuraceoides is reported from white sand in a savannoid ‘tabuleiro’ forest in Paraíba, Brazil. Prior to that, it was known only from the Guiana Shield and the Brazilian and Colombian Amazon Basin. The specimens are characterized by the persistent but not abundant primary thallus, and short, mostly simple, ecorticate podetia, melanotic towards the base, without isidioid, reflexed microsquamules, but macrosquamulose, with flattened, submembranous squamules with short-digitate edge.
