Buellia cranwelliae

Taxonomy

Described originally by Alexander Zahlbruckner in 1941 as B. cranwellii, named after New Zealand Botanist Lucy Cranwell. Referred to as B. cranwelleae by David Galloway in his Flora of New Zealand, Lichens 1985 and the revised Flora of New Zealand, Revised Second Edition 2014. The currently accepted name for this species is B. cranwelliae.

Description

Buellia cranwelliae is characterized by: the saxicolous habit (coastal rocks); the grey-white, areolate thallus; innate to sessile, scattered, black apothecia; a brown-black hypothecium; and biseriate, brown, ellipsoidal to oval or fabiform ascospores, 11-13 × 5-6 μm.

Distribution

Found in southeastern Australia (New South Wales), Tasmania, throughout New Zealand from Northland to Canterbury, and also on the Kermadec Islands.

Conservation status

B. cranwelliae is listed as At Risk - Naturally Uncommon in the 2018 NZTCS. The qualifiers for the status include Range Restricted, Secure Overseas (?), and Sparse.
