Cetraria subalpina #

Taxon #

Cetraria subalpina

Organization #

Rag-Like Parmelioids

Identification #

Cetraria subalpina can be separated from similar species by a combination of morphology and substrate. C. subalpina grows commonly on tree bases and branches. Most other cetraria lichens are predominantly terricolous, bryocolous, or lignicolous but not commonly on living trees as C. subalpina. C. subalpina typically has less cilia or marginal projections than other species. It is similar to some species of Tuckermannopsis but with generally more elongated, narrow, erect lobes.

Substrate #

corticolous, ramicolous on shrubs, terricolous among heaths (Spribille et al. 2023)

Notes #

Possibly of all Alaskan Latitudes, known from SE Alaska north to Utqiagvik (CLH, Spribille et al. 2023)
