LICHALP

Tetramelas pulverulentus (Anzi) A. Nordin & Tibell

Syn.: Abrothallus pulverulentus Anzi, Buellia convexa Th. Fr., Buellia pulverulenta (Anzi) Jatta, Diplotomma pulverulentum (Anzi) D. Hawksw., Karschia pulverulenta (Anzi) Körb., Leciographa muscigenae (Anzi) Rehm

Lichenised.

Substrate: , plant debris,

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a holarctic endoparasitical lichen (it grows inside the thalli of Physciaceae, but with its own photobiont); certainly more widespread in the Alps, but much overlooked in the past; most frequent above treeline, but descending below the oroboreal belt in dry-continental regions.
