Biatora chrysanthoides

Biatora chrysanthoides is a species of corticolous (bark-dwelling), leprose lichen in the family Ramalinaceae.^[1] It is found in Norway, the Pacific Northwest of northern North America,^[2] Sweden,^[3] and Russia.^[4] It was formally described as a new species in 2003 by the lichenologists Christian Printzen and Tor Tønsberg. It contains gyrophoric acid in both the thallus and the apothecia (fruiting bodies), resulting in a C+ (quickly reddish) chemical spot test reaction. Its ascospores are 9.3–10.7 by 3.2–3.3 μm.^[2]
