These were growing in disturbed ground/debris @ ~ 3600ft.
The younger ones were partially underground.
Fruit bodies ~ 5 cm wide.
They appeared to have a indistinct subgleba and did have a rhizomorphic cord attachment.
Spores appeared to be released through lower level cracks rather than a apical opening.
Spores were brown to olive brown.
Spores were rather large, ~ 4-6 microns plus long spines.
Capillitium appeared unbranched.
I’m getting dead ends using various keys??

Edit 4-26-2014; I think the very spinose spores rule out the C. agaricoides.
Fred Stevens suggested Calvatia fumosa, which fits most of the characteristics pretty close except these did not appear to have a thick peridium and did appear to have a subgleba. Fred is going to look at them.

Fred suggests we leave it as Calvatia lycoperdoides

until it gets published in a valid Journal.
Also, there is likely to be three authors on the name.

What’s the protocol on that?

I guess if it’s published in a Master’s thesis, it is as legit as any other nom prov on MO.

Should we also add

C. vernimontanum nom prov S. Jarvis?

Based on what Fred Stevens found,

it looks like Calvatia lycoperdoides is the best name for these…at least for the time being.

“Hi Ron-
I looked at your specimens, and they’re not Calvatia fumosa. This is
what Alexander Smith described (probably) as Calvatia lycoperdoides.
The important characters are the rhizomorphic rooted base,
furfuraceous-spinulose exoperdium, the tendency of the exo and endo
to remain fused, exo spines with connivent tips, the peridium
cracking in age, not forming an ostiole, and habitat under montane
conifers particularly pine in the spring. Microscopically it is
characterized by relatively large, spinulose spores, and a somewhat
fragmentary, only slightly branched capillitium that has abundant
pores, some of which are sinuous. For the latter reason Kreisel
placed it in Handkea, a genus which we now know is polyphyletic and
has been abandoned. Problems with Smith’s Calvatia lycoperdoides
include the fact that it is a homonym of a Polish puffball that
pre-dates Smith’s publication. Complicating matters is that the type
of Smith’s C. lycoperdoides has been lost and to make matters
worse, paratypes on which his original description is based are a
mixed collection and represent at least two different puffballs. Thus
Smith’s species among other things is a nomen dubium. Stephanie has
chosen to provisional rename it Lycoperdon vernimontanum as the ITS
places it in the middle of Lycoperdon. Interestingly, Lycoperdon
umbrinum, the blackish puffball that we find commonly along the coast
in the fall, is fairly closely related and in a sister clade.”

Your microscopy is inspiring. I agree now, after reading a little more, those micro features do not match C. agaricoides. Calvatia/ Gastropila? fumosa looks like a good fit generally.
