Differs in the form of the somewhat scattered conglomerate

Intimately related to L. aphanoides, from which it is distinguished 

 by the darker colour of the hypothecium and by the longer spores. 

 The single specimen, which is only sparingly fertile, was associated 

 with Lecanora smaragdula f. sinopica and with Lecidea contigua 

 var. flavicunda, the latter of which it partially overruns. 



Hab. On a granitic boulder in an upland tract of a mountainous 

 district. — B. M. Craig Guie, Braemar, Aberdeenshire (the only
