General Description

The taxa idenified as this from small wound tracks on old Beeches in the New Forest pasture woodlands, has now been redetermined as a pigment deficient form of Scutula circumspecta.

Identification

A rare pigment deficient form of Scutula circumspecta has been encountered in the New Forest where it was originally recorded as "Bacidia assulata auct. brit., non (Körb.) Vězda (1967)". This has pale red-brown apothecia and lacks both the dark purple-brown, K+ intensifying purple pigment in the upper exciple and the blue-green epithecium pigment. Otherwise it is identical with the typical form and the pale straw hypothecium pigment is still present and extends into the exciple
