In urban and somewhat polluted site. Poorly developed paddlelike structures. Growing in association with a foliose lichen and Ramalina on 'Black boy' peach limb. Not plentiful and T. chrysophthalmus present on neighbouring plum tree which was also growing foliose spp of lichens.
Bonus was discovering the tiny gastropod top left [which is likely a grazer of lichens] when pix reached computer.
