LICHALP

Biatorella microhaema Norman

Syn.: Strangospora microhaema (Norman) R.A. Anderson

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, perhaps circumpolar species with minute, blood-red, immarginate apothecia, whose taxonomic position is still unresolved; on base-rich bark and slightly eutrophicated lignum with a few scattered records from the Alps.
