The Worlds’ Rarest Mushroom
A star-shaped mushroom, called the Devil’s Cigar (Chorioactis geaster) is one of the world’s rarest fungi. It’s also known as the Texas star. These fungi had been detected only in central Texas, two remote locations in Japan, and most recently in the mountains of Nara. The Devil’s Cigar is a dark brown cigar-shaped capsule that transforms into a tan-coloured star when it splits open to release its spores.
It is also one of only a few known fungi that produce a distinct whistle sound when releasing its spores.
