Strigula stigmatella var. stigmatella

Description & Identification
Similar Species

Microscopic examination to establish the identity of the photobiont (Trentepohlia), the form of the asci (thickened tholus with ocular chamber) and the ascospore-type (fusiform, (3-)7(-(9)-septate) is essential in order to distinguish it from various similar-looking genera, such as Anisomeridium, Celothelium, Porina, Rhaphidicyrtis & Thelenella, and other species of Strigula.

Records from Wales

S.stigmatella has been found but once growing epiphytically in Wales, on an old Quercus in a relic fragment of upland broadleaved woodland at Hafod, near Pont-rhyd-y-groes, E of Aberystwyth, in 2000 (Chambers, 2000).
