This is one lichen you wont notice unless it has these pinkish little knobs on it . It is otherwise an insignificant grey crustose lichen, best described as a grey powder on a dirt bank.
It was once known as Baeomyces fungoides which means "little fungus" because of its appearance when it sends up these reproductive structures.
The pink knob part is called an "apothecium" and it bears the spores of the fungus of this lichen.
These are less then 1 cm tall, and can be found almost year round on banks and rocks.
