Must be loosing it.

Thanks for reminding me, Danny. I should have used the term sequestrate. Meaning isolated, unable to liberate by themselves. So similar to secotioid, in that sequestrate fungi which are often hypogeal, require animal mycophagy for spore liberation and dispersal.

Some of the photos do appear to show a pure-white gleba, typical of immature Calvatia. Yet microscopy shows mature spores.

Thanks for the selection of wrinkled peridiums on mature Calvatia, especially Calvatia rubroflava. I do not find that species in my area. To my eye, C. rubroflava appears squashed or stepped on, while this obs. appears much more globular.

In regard to the wrinkling, this obs. to my eye appears wrinkled mostly longitudinally with marginal latitudinal wrinkling.

While several photos seem to show visible gleba, I remain unconvinced spores are liberated via those exposures.

I meant to say the spore might well be sequestered.

…? do you mean secotioid? this is not secotioid. Take a look at the Calvatia pyriformis group as Alan’s proposed. This is the right track. If the wrinkles are throwing you off, see the following obs:


The gleba has the appearance of a Rhizopogon or Gymnomyces.

…the glebal surface…

Details of the gleba and base are still lacking.

Your first two uses of ‘gleba’ seem like they ought to be ‘peridium’ instead. You’re correct that we don’t have details on the gleba yet, because it’s inside the puffball, underneath the peridium; the layer of tissue that contains the gleba.

The one part of Mushrooms Demystified that is globally applicable is the glossary. I revisit it frequently myself.

Should not have used “gastroid”

I meant to say the spore might well be sequestered. The gleba has the appearance of a Rhizopogon or Gymnomyces. It lacks rhizomorphs, making Rhizopogon unlikely. Still the glebal surface reminds me of it somewhat. Something near Gymnomyces is still possible, at least in my mind if no one else’s. Truly it is nothing I have ever seen or remotely seen before. It is not immature with that amount of spores present, Clive.

Details of the gleba and base are still lacking. Need sliced specimen.

This looks to be a immature Calvatia sp. I have seen them with wrinkles surfaces and had put it down to dehydration during development.

Definitivamente no es una “puffball” la consistencia del tejido interno es esponjosa solida. si observan la fotos veran rajaduras profundas.Esto no occurre en las puffballs. Voy a colectar nuevo material para hacer observaciones Mas detalladas.

I think you’re confusing the term ‘gastroid’ to mean ‘Geastrum-like’. ‘Gastroid’ and ‘puffball-like’ are synonymous. ‘Gastroid’ refers having a stomach-like appearance, as in the gastrointestinal system. That would include Geastrum as much as it would Lycoperdon.

The wrinkles seen here are not sign of ectoperidial arms in the making. They are just wrinkles. There is no chance this is an earthstar.

wrinkling of gleba in latitudinal lines reminds me more as a gastroid feature than a puffball. To me it further suggests the possibility of the sporocarp developing rays that open up to expose the gleba, similar to Geastrum and Arachnium.

two things

1. stalked puffball from Panama:


2. “This looks to me more gastroid than puffball-like.”


You’re right, Danny.

When Tulostoma is grown in arid conditions, the stalke is much longer, and the spore area much compressed. These, however, are in Panama in a much more humid environment. This looks to me more gastroid than puffball-like. But without a cross-section plus a close look at the base that’s just a guess.

Tulostoma is much, much more stalked and slender. Compare with other photos and you’ll see they look pretty much nothing alike. Calvatia would be my guess.

Terrestre, forma grupos de hasta 10 en menos de 1 metro cuadrado. El especimen fue hallado a mas o menos 600 metros de altura.

Photo of sliced sporocarp cut through the base, Eduardo. Looks somewhat similar to some of the Tulostomas: stalked puffballs. But details are in the sterile base, if any; plus the substrate (wood or terrestrial?).
