For the second time this year, a rare hissing mushroom was spotted in Texas at a state park in Hill Country.

Known as the Texas star mushroom, the fungus is highly selective about where it grows, according to the Fort Worth Botanic Garden. The mushroom tends to grow on decaying cedar elm stumps in North and Central Texas.

It has made appearances in more than a dozen Texas counties, including Dallas, Tarrant, Collin and Denton. It has also been spotted in Oklahoma and perhaps surprisingly, Japan, making it one of the world’s rarest mushrooms.
