Vezdaea leprosa (P.James) Vězda

Description: A tiny species, it is associated with soils below corrugated zinc roofing of old outbuildings or the metal-rich drip zone of wire boundary fences. The thallus is composed of pale green warted granules with clusters of pink to orange discs which resemble little fatty granules rather than 1 disc-like fruits. The simple to one-septate spores are cylindrically shaped. This is primarily a lichen of forgotten or neglected urban landscapes. Records are few and scattered, mainly in the northern counties.

Key Identification Features:

  • Thallus crumbly-granular, pale green, a smear when wet with tiny pink or orange discs
  • Directly below metal objects exposed to the elements including posts, wires, pylons, etc.
