These puffballs were just a little over an inch across and had openings at the top from which the spores exited.
The wind came in gusts and had a double effect on the fungi. Strong gusts would physically shake the puffball and produce a substantial plume of spores.
Gentler winds produced a more subtle removal of spores. Spores are forced from the opening as the moving air produces an area of low pressure outside the enclosed globe. I once demonstrated this phenomenon to someone by gently blowing over the opening in the puffball and producing a stream of exiting spores. I passed the puffball over for her to try, but instead of blowing across the hole, she blew into it and got a face full of spores for her trouble. Needless to say, I was accused of perpetrating some elaborate practical joke. My defensive arguments were severely weakened by my laughter.
You should submit some of these photos for publication is a nature magazine. They're excellent.
ReplyDeleteHI Steve...fascinating photo...crazy to be able to see those spores in a photo ..very good!!
ReplyDeleteNow to the weirdness of it all of you laying in the grass with these spores just floating about...possibilities are that you are right...I didn't see the ghostly women...hmmm,but I did see what looked like the head of the Tyrannoraurus Dinosaur ; }
Those spores must be floating my way..lol
When I was a kid we loved stomping on them...!!

Thanks Mark.
ReplyDeleteHi Grace. I can see the dinosaur, but it looks to me like a friendly one.
