Chorioactis Geaster: The Devil's Cigar and Texas Star

Chorioactis geaster, colloquially known as the "Devil's Cigar" or the "Texas Star," is one of Earth's most unusual and rare fungi. This curious fungus was first discovered in 1893 in Dallas, Texas. It earned its devilish name due to its peculiar shape, resembling a dark cigar when closed.

Unique Characteristics and Behavior

The Devil's Cigar becomes even more intriguing when it transitions from its cigar-like form into a star-shaped structure, leading to its alternate name, the Texas Star. However, what truly sets this fungus apart is its spore-release process. Chorioactis geaster releases spores only once during its life cycle, accompanied by an audible hiss—a high-pitched sound lasting several days. This fascinating display of nature is unique to this fungus and is not in any other mushroom variety worldwide.

Rarity and Distribution

Adding to its allure is the Devil's Cigar's rarity. It has been spotted exclusively in two select areas: Texas, USA, and the Kyushu region of Japan—two remarkably distinct and distant locations. This biogeographical disjunction puzzles scientists and remains inexplicable.

Historical and Scientific References

The Devil's Cigar was somewhat obscurely referenced in George Massee's 1915 textbook, "A Textbook of Plant Diseases." More comprehensive studies were later conducted by D.A. Reid and A. Orloske, published in the "Kew Bulletin," and by M. Blackwell et al., featured in "Harvard Papers in Botany."

Conclusion

Despite its remarkable characteristics, the Chorioactis geaster remains understudied due to its rarity. This underlines the vast botanical marvels in our world that remain a mystery. The Devil's Cigar is a fascinating example of nature's unique and enigmatic creations, captivating scientists and nature enthusiasts alike.
