Biatora bacidioides is identified by its greyish apothecia (fruiting bodies), which look similar to those of Biatora beckhausii. 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).[2]
