Lindbergia is a journal opposing the tracheophytocentric conception of the world, and publishes original scientific research from bryology and lichenology.

A liverwort and hornwort checklist is provided for Peru. The list is based on over 800 literature references, including monographs, regional studies, and molecular investigations. We report 702 accepted species (including 75 species here reported as new to Peru), 41 doubtful species and 60 rejected species previously reported for Peru. This is a substantial increase from the 508 species reported in the previous checklist published in 1984. We validate one name and typify 23 taxa and identify over 100 more names in need of typification. Peru, due to its diverse physical geography and climate, harbours remarkable biodiversity. However, the knowledge of its liverwort flora (and bryoflora in general) remains limited compared to vascular plants, birds, mammals and herpetofauna. We predict that further fieldwork, coupled with scrutiny of collections in Peruvian and other herbaria, will enhance the number of new liverwort records for the country, in particular the addition of regionally widespread species recorded in neighbouring country checklists but not yet from Peru.

We present an updated checklist for all bryophyte species known to occur in the Nordic countries and list occurrences for each taxon from Iceland, the Faroe Islands, Denmark, Svalbard, Jan Mayen, Norway (mainland), Sweden and Finland. Altogether 1276 bryophyte species are included for the region. The checklist includes vernacular names in Icelandic, Danish, Norwegian, Swedish and Finnish. The following new nomenclatural combinations are proposed: Scapania scandica var. parvifolia comb. nov., Andreaea alpina var. hartmanii comb. nov., Didymodon islandicus comb. nov., Ephemerum serratum var. stoloniferum comb. nov., Hygroamblystegium varium var. fluviatile comb. nov., Hygroamblystegium varium var. tenax comb. nov., Ptychostomum arcticum var. purpurascens comb. nov., Ptychostomum intermedium var. nitidulum comb. nov. and Ptychostomum warneum var. mamillatum comb. nov.
Tuber viability was assessed in seven collections of Rosulabryum capillare from four Mojave Desert (USA) localities that had been stored desiccated in the dark for 25–30 years under conditions of low relative humidity (approximately 35% at approximately 23°C). While all 7 of the collections had at least two germinating tubers and 20% of tubers germinated overall, most of the viable tubers were from three collections, with one 25-year old set of tubers exhibiting 100% germination. The maximum duration dry found was 30 years and 6 months for six tubers from the Eldorado Mts, Nevada, USA. Tubers 28 years old were cultured to mature female plants in single clone cultures that produced germinable tubers of G. capillare after a year. Germination of tubers after 30 years of desiccation is consistent with earlier longevity reports, and may be near the ceiling of survival for bryophyte tubers.
The basidiolichen Bryoclavula dryalisepiplutea with clavarioid basidiomata was recently described from Texas (USA). The species is here reported from the Netherlands, where it was found on loamy soil in open patches in a heathland. It is the first record of a Bryoclavula species from Europe, where up till now the only known species of clavarioid basidiolichens belonged to the genus Multiclavula. The ITS and LSU sequences of Dutch material showed a 100 and 99.3% match with sequences of the holotype of Bryoclavula dryalisepiplutea, respectively. Bryoclavula dryalisepiplutea is phylogenetically distinct from Bryoclavula phycophila, known from Japan and currently the only other species from the genus. However, the two Bryoclavula species are morphologically similar, and the Dutch material is morphologically intermediate between the type descriptions of Bryoclavula dryalisepiplutea and B. phycophila. Hence, the usefulness of morphological characteristics for identification of the two Bryoclavula species is discussed.
