Tromera resinae (Fr.) Körb.

Syn.: Biatorella resinae (Fr.) Th. Fr., Sarea resinae (Fr.) Kuntze, Sphaeria resinae Fr., Tromera myriospora (Hepp) Anzi

Non- or doubtfully lichenised.

Substrate: resin

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 non-lichenised discomycete with medium-sized, orange to reddish apothecia (to 1.5 mm in diam.) recalling those of Bacidia rubella, polyspored asci, and spherical ascospores (2-3 µm in diam.), sometimes accompanied or replaced by an anamorphic pale orange pycnidial state with spherical, hyaline conidia; growing on the resin of coniferous trees in the upper montane and subalpine belts; widespread in the Holarctic region, both in Europe and in North America, and also recorded from the Himalayas and the East African highlands; not rare throughout the Alps.
