The lichen Bacidia incompta does not have a common name. The Generic part of the scientific name, Bacidia means 'rod-shaped' and refers to the shape of the spores, called 'ascospores', which develop inside a tiny bag-like structure known as the 'ascus' (3). The specific part of the name, incompta is derived from the Latin word 'incomptus', which means untidy or unkempt, and refers to the scrappy outline of this lichen (4). This lichen grows as a whitish-fawn (5) or greyish-green crust with brown or blackish fruits, which look like dots (6).
