A few, several years ago, I ran across an article that described a ground organism in the wild that when its environment became too harsh for survival they would come together and form or grow a stalk so they could catch the wind and travel to a better location.
Time has eroded many of the details of that article from my memory and I don't remember if it was a fungus or spore, but I do recall they had a name for it and had a drawing showing the stalk formed. I believe it was a PBS or NPR article but my searches have come up with nada.
Anyone know what that might have been?
