Usnocetraria oakesiana (Tuck.) M.J. Lai & J.C. Wei

Syn.: Allocetraria oakesiana (Tuck.) Randlane & A. Thell, Cetraria bavarica Kremp., Cetraria oakesiana Tuck., Cetraria ochrocarpa (Eggerth) Lettau, Platysma oakesianum (Tuck.) Nyl., Tuckermannopsis oakesiana (Tuck.) Hale

Lichenised.

Substrate: bark, lignum

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: a cool-temperate to boreal-montane, incompletely circumpolar species found on basal parts of conifers in humid-cold montane forests, more rarely on lignum (e.g. on stumps); widespread throughout the Alps, but generally not common, and probably declining.
