Taxonomic notes


Why suggested for a Global Red List Assessment?

A highly unique member of the Pezizales with a very limited disjunkt distribution.

How cool is this thing? Like a cross between a cup fungus and an earthstar, Chorioactis geaster is found only in a few Texas counties and one prefecture in Japan. Texas collections like the one illustrated here are usually associated with decaying cedar elm stumps. At first, this mushroom looks like a tiny, fuzzy American football—but it soon begins to expand and peel back into star-like rays, as the color of the upper surface progresses from whitish to brownish orange to, finally, dull yellow.

it is the official state fungus of Texas.


Geographic range

According to genetic studies (Peterson et al. 2004) the Japanese and Texanian populations were separated into two lineages about 19 million years ago.
