LICHALP

Stenocybe major Nyl. ex Körb.

Syn.: Calicium eusporum Nyl., Stenocybe euspora (Nyl.) Anzi

Non- or doubtfully lichenised.

Substrate: bark

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 non-lichenised species characterised by ascomata with unbranched or furcate stalks, and narrowly clavate capitula (together up to 1.5 mm high), with light brown, 4-celled, narrowly ellipsoid ascospores (19-32 × 5-7 µm); on trunks of old trees, especially Abies, in humid montane forests, sometimes breaking through thalli of Loxospora-species and then virtually lichenicolous; widespread in temperate Europe and North America, but not common.
