Sarcogyne (Acarosporaceae) on calcareous rock in Europe and North America

Abstract

Knudsen, K., van Zon, S., Tsurykau, A., Kocourková, J., Hodkoavá, E., Huereca, A. & Malíček, J. 2023. Sarcogyne (Acarosporaceae) on calcareous rock in Europe and North America – Herzogia 36: 52–71.Sarcogyne pruinosa and S. regularis are revised and lectotypes selected. Sarcogyne pruinosa is recognized as oldest name for the species and S. regularis as a synonym. The description of the species is revised. Sarcogyne pruinosa does not occur in North America. Two new species are described, Sarcogyne nimisii from Italy and Sarcogyne belarusensis from Belarus, Germany and Italy. Sarcogyne platycarpoides is lectotypified and S. melaniza is recognized as its synonym. New records are reported of S. distinguenda and S. nivea from the Czech Republic and Italy and S. fallax from the Czech Republic. A key is supplied for 14 species of Sarcogyne on calcareous rock in Europe.

Exploring the Sarcogyne phylogeny: three new species and four new reports from Europe and North America (Austria, Czech Republic, Greece, Germany, Romania, U.S.A.)

“…Sarcogyne No. 3 & 4 were previously published in a phylogeny and resolved in the circumscription of Sarcogyne coeruleonigricans ( Knudsen et al 2023a, b). New sequences are published for the first time of Sarcogyne clavus from North America (California), Acarospora imbriculata from Italy ( Nimis 2016), A. irregularis from the Czech Republic and A. boulderensis H.Magn.…”
