for the explanation. It looks like a volva to me as it is ragged at the edge where the bulb meets the stem but there are no collar/flap remnants. I don’t have any Melzer’s reagent and have been unable to acquire it.

Regards,

Teresa

That big bulb does seem unusual.

Do you have Melzer’s reagent to check the amyloidity of the spores?

A bulb is not the same as a volva.

The bulb is often simply tissue that didn’t develop into specialized tissue. You might think of it as the remnant of the primordium whose role in development was not to transform utterly into a specialized tissue. It doesn’t become full of water-driven pistons like the stem (for example) and it doesn’t become a protective coating (like the universal veil) that has to have a method of breaking up, or simply breaking, in order to let the fruiting body do its spore generating thing.

The bulb is the bulb.

The volva is the volva.

They have a very long term realtionship, but they’re “just friends.”

Very best,

Rod

cap shots?
