Name: Lecidella meiococca (Nyl.) Leuckert & Hertel in Leuckert, Knoph & Hertel (1990)
Pronunciation: Lecidella meiococca
Conservation Evaluation: Least Concern, Nationally Scarce.
Body Type: Crustose
Description: The thallus is buff yellow-orange and is thin to thick depending on the degree of budding of propagules (blastidia) on the thallus surface. A dark prothallus may be present if it abuts against other crustose lichens. Apothecia are few and scattered and are generally less than 1 mm in diameter. They differ in colour from the thallus, being almost black with a thin rim. The discs are flat to slightly convex.
Chemical Tests: K+ yellow, C+ orange.
Nature Notes: A coastal species found on silica-rich hard rock exposed to direct sunlight. Easily confused with Lecidella asema which has a coarser thallus than L. meiococca.
