Texas Star

Fungi: Ascomycota: Pezizomycetes: Pezizales: Chorioactidaceae: Chorioactis geaster (Peck) Kupfer ex Eckblad

Chorioactis geaster – Texas Star

Synonyms: Kumanasamuha geaster, Urnula geaster.

Common names: Texas Star, Devil's Cigar.

Extract from Wikipedia article: Chorioactis is a genus of fungi that contains the single species Chorioactis geaster. The mushroom is commonly known as the devil's cigar or the Texas star in the United States, while in Japan it is called kirinomitake (キリノミタケ). This extremely rare mushroom is notable for its unusual appearance and disjunct distribution; it is found only in select locales in Texas and Japan. The fruit body, which grows on the stumps or dead roots of cedar elms (in Texas) or dead oaks (in Japan), somewhat resembles a dark brown or black cigar before it splits open radially into a starlike arrangement of four to seven leathery rays. The interior surface of the fruit body bears the spore-bearing tissue known as the hymenium, and is colored white to brown, depending on its age. The fruit body opening can be accompanied by a distinct hissing sound and the release of a smoky cloud of spores.

Arabic: كوريواكتس, French: Chorioactis, Russian: Хориоактис.
