Observation 104875: Erioderma pedicellatum (Hue) P.M. Jørg.
When: 2010-08-01
No herbarium specimen

Notes: 2010-10-25: Erioderma pedicellatum still alive in Europe

The globally critically endangered lichen Erioderma pedicellatum is still present at one of its two known European localities.

The Boreal Felt Lichen, Erioderma pedicellatum (CR: Critically Endangered), is the only Norwegian terrestrial organism in the two top categories (CR and EN) on IUCN’s global red list of threatened species.

One of its two known remaining localities in Europe was visited by Einar Timdal this summer (August 2010), and a single specimen (photo) was found on the twig where two specimens occurred in 2003. The locality is situated in Grong municipality, Nord-Trøndelag county, Central Norway. The other European locality is in Rendalen municipality, Hedmark county, Southeast Norway, but has not been visited since its discovery in 2005 – only a single specimen was seen at that site.

Erioderma pedicellatum is the only boreal member of a mainly tropical/subtropical lichen genus. It occurs elsewhere in North America.
