[1] Ulf Arup and colleagues transferred the taxon to the genus Flavoplaca in 2013 as part of a large-scale reorganisation of the family Teloschistaceae.

Some areoles have a thin, whitish pruina at the centre and are covered in a richly blastidious margin that eventually becomes enveloped in a soredious mass.

[1] Flavoplaca kantvilasii shares similarities with C. citrina, yet it can be distinguished by its notably thicker and more convex areoles or squamules.

Additionally, F. kantvilasii features smaller blastidia and larger conblastidia, and its asci contain a varied number of ascospores that exhibit a broader size range.

In contrast to another sorediate species, C. cranfieldii, which is also discussed in this study, F. kantvilasii is characterized by its thick and highly convex areoles or squamules, which uniquely have margins that curve upwards.

This species is also adaptable to artificial environments, thriving on man-made materials such as building blocks and asbestos sheeting.
