Toensbergia blastidiata

Toensbergia blastidiata is a species of crustose lichen in the family Sporastatiaceae. Described in 2020 from specimens collected in Glacier Bay National Park and Preserve, this bark-dwelling lichen is widespread across northwestern North America from Alaska to Washington State. It is distinctive for producing coral-like clusters of powdery reproductive structures called blastidia, and dried specimens often turn pink due to the oxidation of a lichen product called alectorialic acid.
