Lambiella

Lambiella is a genus of lichen-forming fungi in the family Xylographaceae. These lichens form tightly adhering crusts that range from pale grey to deep black and are characterized by distinctive black reproductive structures with raised rims that often become ridged or lobed. The genus was established in 1984 by the German lichenologist Hannes Hertel and is named in honour of the British polar explorer and lichenologist Elke Mackenzie, with molecular studies in the 2010s confirming its status as a distinct group.
