This is a parasitic species (lichenicolous) of rosette-forming Caloplaca thalli such as C. flavescens and C. cirrochroa. Signs that the host thallus may be parasitised include a browning and subsequent wrinkling of the host cortex. Discs (perithecia) are rather deeply embedded in the areoles (fragments of thallus) with just the tops visible. The spores (1019m long) are narrowly ellipsoid with an occasional concave side. Very few records; rare.

Key characteristics

  • Lichenicolous on Caloplaca lichens, particularly rosette-forming taxa
  • Thallus brown, cracked like dried mud and wrinkled; perithecia frequent, immersed, spores narrowly ellipsoid.
