Haha, very cool! Now we just need a video of H. lacunosa “puffing”. I’ll have to try next time i run across them.

And here is a link to a thread with video and photos of some Cup Fungi “puffing” spores. It’s really cool looking, you should definitely check it out:

Wait, H. lacunosa “puffs” spores??

I’ve seen it personally while trying to collect Peziza and instead, getting powdered with spores each time I agitated the mushrooms. Even after picking, I kept getting puffed in the face as I tried to carry a box of mushrooms down a hill.
Tapping or blowing on them seems to cause the discharge of a cloud of spores.

So then, can all Ascomycetes “puff” spores?

Hehe, looks like Tom and everyone are having a good time at SOMA. I’ll have to try and make it next year.
