Lecidella elaeochroma f. soralifera
A soorediate form of Lecidella elaeochroma f. elaeochroma, always with apothecia and the soralia are UV+ yellow. It occurs in similar habitats to, and usually with, f. elaeochroma, but is less frequent and is is most common near sea coasts.
This is similar to Lecidella elaeochroma f. elaeochroma but has bright yellow-green soralia, 0·5–1 mm diam., punctiform and discrete, scattered all over or restricted to only part of the thallus. Apothecia are always present and the production of soralia does not inhibit their formation. The soralia possess lichexanthone and are UV+ yellow.
Its recognition as a distinct taxon needs further evaluation.
It occurs in similar habitats to, and usually with, f. elaeochroma, but is less frequent.
It is most common near sea coasts, mainly in W. Britain.
