LICHALP

Microcalicium ahlneri Tibell

Non- or doubtfully lichenised.

Substrate: lignum

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: on decorticated stumps of conifers heavily attacked by brown rot fungi, more rarely of deciduous trees, often in cavities and cracks, confined to humid upland areas; probably overlooked in the Alps, but certainly never common.
