Observation 24993: Bovista Pers.

Not sure these are the same stuff, although they looked like different stages of the same species and they grew close together (at a few m distance, not in a group) in the same habitat. Spores in the picture are taken from the mature one with large crack. To my limited understanding field characters do not correspond well to any of the ‘common’ Bovista (B. aestivus, B. pila, B. nigricand, B. plumbea). There were many of them there; none had a distinct, small apical opening at the top. Can anybody help me?

Thank you Darv. I was considering B. plumbea too but was confused by the following. I was unable to find a picture on net with such distinctly rimose-areolate exoperidium (although I found one recently – http://www.mykoweb.com/CAF/photos/Bovista_plumbea(fs-03).jpg ). Also most of mature specimens (with that I think already cracked fruiting body) still had their exoperidium more or less intact. I didn’t observe its peeling or flaking away. Actually I found only one example without it having typical lead-gray endoperidium visible (pic 55871). In addition, MW California Fungi page states for B. plumbea ‘ … spores released via a small apical pore… ‘ which was clearly not true in my case. All this diverted me form B. plumbea. May be high elevation of the observation explains all this? Thank you for your time again. I am learning.

Bovista plumbea seems like a good fit based on Pegler’s British Puffballs, Earthstars and Stinkhorns book. It open with a crack, not a pore and the spores look like a perfect match. NICE series of photos and excellent documentation.
