Typification and emendation of Seirophora Poelt to include species segregated from Teloschistes Norman

The type material of Physcia magara Kremp., which is the type species of Seirophora Poelt (Teloschistaceae), is shown to be heterogeneous. It is a mixture of Teloschistes villosus (Ach.) Norman and Ramalina maciformis (Delile) Bory. Physcia magara Kremp. is typified on the T. villosus-part. Teloschistes species with multiseriate hairs, spores with short septa, thick and strongly conglutinated cortex hyphae with thick walls, lacking cilia or rhizines, and which have a mainly northern hemispheric distribution, are transferred to Seirophora. The following new combinations are made: Seirophora aurantiaca (R. Br.) Froden, Seirophora austroarabica (Sipman) Froden, Seirophora californica (Sipman) Froden, Seirophora contortuplicata (Ach.) Froden, Seirophora lacunosa (Rupr.) Froden, Seirophora scorigena (Mont.) Froden, Seirophora stenophylla (Tav.) Froden, and Seirophora villosa (Ach.) Froden

Chemosyndromes in the lichen genus Teloschistes (Teloschistaceae, Lecanorales)

The secondary metabolites of 150 specimens belonging to 29 species of Teloschistes were analysed with HPLC. Seven anthraquinones were detected of which parietin dominated with minor proportions of emodin, teloschistin, fallacinal and parietinic acid. The depsidones vicanicin, caloploicin, and isofulgidin occurred together with some compounds of unknown identity in varying proportions in T. flavicans, T. peruensis, T. stellatus, and one unnamed taxon. Nine chemosyndromes were found in the genus. Most species had only one chemosyndrome, but T. flavicans s. lat. had six syndromes. The geographical distribution patterns of these chemosyndromes in T. flavicans are discussed as well as the applicability of chemical characters for species delimitation in Teloschistes

Candelaria fibrosoides – a new species from Peru.

The new species Candelaria fibrosoides is described. It is known from one locality in Ayacucho in Peru where it was found growing at high altitudes on shrubs and cacti in open pasture land. The new species is superficially similar to C. fibrosa but differs in having 8-spored asci and a thallus with an ecorticate lower surface

Josefpoeltia parva, a new combination in Josefpoeltia (Teloschistaceae)

The new combination, Josefpoeltia parva (Ras.) Froden. & L. Lindblom with the basionym Xanthoria parva Ras., is made. The type species of Josefpoelfa, J. boliviensis, is reduced to synonymy with J. parva. The length of the conidia varies in J. parva showing a north-south gradient

Liten getlav Flavoparmelia soredians ny för Norden

Liten getlav upptäcktes nyligen i östra delarna av Lund i Skåne, vilket var det första kända fyndet från Norden. Patrik Frödén har fotograferat merparten av arterna i familjen Parmeliaceae inför det kommande bandet av Nordic Lichen Flora och Arne Thell är en av författarna till verket. Här ger de en beskrivning av hur det gick till när detta nytillskott i vår flora uptäcktes

Erik Acharius - the last of the Linnean pupils.

Erik Acharius, Linnaeus last pupil and accounted as "The father of lichenology", was born 250 years ago, on the 10th of October 1757. After graduating in Uppsala and taking his medical degree in Lund, he eventually settled in Vadstena, where he worked as a provincial doctor and chief physician at the hospital for veneral diseases. At the age of 36 he wrote his first lichenological work and then continued to work relentlessly on lichen systematics until his death in 1819, expanding the knowledge of this group enormously. He described many new species and genera which still are recognized, and his lichen system was recognized worldwidely. After his death a series of unfortunate events led to that his valuable lichen herbarium was sold to Helsinki. The majority of the herbarium, though, was donated to Lund university in 1843, and we are proud to preserve this in the Biological museums today
