Shackletonia sensu lato ( Fig. 13 )

Only one species was recorded in the territory. Thallus is grey, reduced to tiny fragments surrounding apothecia; lichenicolous on epilithic lichens. Vegetative diaspores are absent. Apothecia are with anthraquinones (chlorinated anthraquinones present). Literature (not including Northern Hemisphere lichens): Arup et al. (2013), Garrido-Benavent et al. (2016).

‘ Caloplaca ’ epithallina : 20 localities at altitudes 300–2900 m in all ecological categories. Substrate: siliceous rocks; lichenicolous on various crusts (rarely on foliose lichens): Aspicilia sp. , Buellia sp. , Dimelaena oreina , Lecanora muralis , Montanelia sp. , Pleopsidium flavum , Protoparmelia sp. , Rhizocarpon sp. , Rhizoplaca peltata and R. cf. subdiscrepans . Anthraquinone content in apothecia (specimen 18287): 7-Cl-emodin (major), parietin (subdominant), emodin (minor), 7-Cl-emodinal (minor), 2 unknown compounds (minor).
