Q: I cannot see artillery fungus in the mulch – just how big is it? Is it the same as those little cups called the “bird’s nest fungus”?
A: The artillery fungus is quite small – the fruiting bodies are about 1/10 of an inch across and are very hard to see in the mulch.
They are much smaller than the “bird’s nest fungus” with which it is often confused. By the way, the bird’s nest fungus does not actively shoot its spores – those little “eggs” of the bird’s nest fungus are splashed out when a drop of rain hits the cup.
