Mood: I was full of piss and vinegar, now I'm just full of vinegar

This thread reminds me of cannon fungus, the only mushroom I've ever had throw something at me.

We get Earthstars in the Santa Cruz area, often in fields alongside Satan's Bolete.








They always say, "He lost his battle with cancer." But as Norm MacDonald pointed out, the cancer dies at pretty much the same time you do, so doesn't that make it a tie?

I guess the cannon fungus accelerates its spores pretty fast. It's amazing how an environment over time constructs such varied creativity, sifting possible outcomes that favor survival or demise.

On hissing mushrooms ....

"The Devil's Cigar (a.k.a. "Texas Star") -- known to botanists as Chorioactis geaster -- had been observed only in central Texas and at two remote locations in Japan prior to the recent discovery in Nara. The peculiar fungus is described as a dark brown cigar-shaped capsule that transforms into a tan-colored star when it splits open to release its spores. It is also one of only a few known fungi that produce an audible hiss when releasing spores."

Hissing Urnula craterium
'I love stimulating cup fungi and watching the spore release. Next time you find one blow into it and wait a couple seconds. The air movement stimulates the mushroom to release the spores. It's almost like it's thinking! When I blew on these Devil's urns (Urnula craterium) they released their spores with an audible hiss! Turn up your volume. This blew me away (no pun intended).'

Chorioactis geaster
"Like other cup fungi, there is a mass spore discharge event that resembles smoke puffing out of the fruit body. This is caused by sudden changes in humidity, and can be induced by blowing a rapid jet of air on the fungus from your lungs. You need to try this the next time you find a cup fungus."

"The fungi featured today is one of the rarest species on Earth. Chorioactis geasteralso known as the devil’s cigar is peculiarly only found in select counties in Texas, and a handful of locations in Japan."

"In 2004, researchers looked compared the genomes of both Texan and Japanese populations. Utilizing molecular clock techniques, these scientists estimate that these populations diverged around 19 million years. So basically 19 million years ago, spores from one location made their way to the second location. With this information, we know that humans didn’t spread the species to the second location, since Homo sapiens has only been walking the Earth for 200,000 years."
