Description:

Synonimy.: Biatorina candida (Weber) Jatta, Lecidea candida (Weber) Ach., Psora candida (Weber) Hoffm., Diphloeis candida (Weber) Clem. - Habitat: steep mountain slope southwest aspect; almost vertical calcareous bedrock ground; relatively warm place; full sun; partly protected from direct rain; average precipitations ~ 3.000 mm/year, average temperature 6-8 deg C, elevations 659 m (2.150 feet), alpine phytogeographical region. Substratum: Cracked, vertical or partly overhanging calcareous rock surface. Comment: Toninia candida seems to be a rather rare lichen in Slovenia. Although Ref. 6 lists a few observations in different phytogeographical regions of Slovenia, Ref. 7 knows a single UTM square with it. A few specimens were found at the place of this observation. Photographed in half damp conditions. Thallus K-, eventually barely noticeable light yellow. No microscopy has been done. Ref.: (1) V.
