LICHALP

Schismatomma umbrinum (Coppins & P. James) P.M. Jørg. & Tønsberg

Syn.: Lecanactis umbrina Coppins & P. James

Lichenised.

Substrate: siliceous rocks

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: a mostly sterile species with a brownish, smooth to tuberculate thallus delimited by a distinct prothalline margin, the tubercles often with apical, concolorous soralia which later coalesce hiding most of the thalline surface, a trentepohlioid photobiont, and containing schizopeltic acid; usually on acidic rocks under overhangs, often with Enterographa zonata; most of the records are from the Eastern Alps, but the species might have been overlooked elsewhere.
