Lectotypification of the name Umbilicaria nylanderiana (Umbilicariaceae)

Abstract

The name Umbilicaria nylanderiana is reviewed and lectotypified using a specimen in the Acharius herbarium at H.

Lectotypification of Umbilicaria virginis (Umbilicariaceae)

“…Although the genus Umbilicaria is among the better known lichen genera, a number of type questions for its species remain to be solved (e.g. Hestmark 1993Hestmark , 2007Hestmark , 2010Hestmark , 2014Jørgensen et al 1994). On 28 August 1841, the already famous paleontologist and glaciologist Louis Agassiz summited the peak Jungfrau (German for 'virgin' or 'maiden') in the Swiss Bernese Alps (46 32 0 12 00 N, 7 57 0 45 00 E).…”

“…2009). Nevertheless, quite a number of its taxa lack proper typification, a task often made difficult by complex histories of synonyms and misidentifications (Hestmark 1993, 2007, 2010, 2014, 2015).…”

“…The circumscription and number of its species is reasonably well known, particularly in Europe (Frey 1933;Llano 1950;Wei & Jiang 1993;Krog et al 1994;Smith et al 2009). Nevertheless, quite a number of its taxa lack proper typification, a task often made difficult by complex histories of synonyms and misidentifications (Hestmark 1993(Hestmark , 2007(Hestmark , 2010(Hestmark , 2014(Hestmark , 2015.…”
