Biatora bacidioides is a species of corticolous (bark-dwelling), leprose lichen in the family Ramalinaceae.

[1] It was formally described as a new species in 2003 by the lichenologists Christian Printzen and Tor Tønsberg, from specimens collected from Picea orientalis forests of north-eastern Turkey.

It has specific spores that are long and narrow (16–47 by 2–4 μm), and it contains a grey pigment in certain tissue layers.

The lichen features light yellowish-green, dot-like growths that occasionally merge.

These growths contain secondary metabolites, including argopsin and gyrophoric acid, which react Pd+ (orange/red) and C+ (red).
