Much more shiny than our common cramp balls.

good question.

I thought the same thing looking thru a European guide the other day! They sure look identical from their macro morphology…grandis is the name attached to the California version of concentrica, and was originally named as a former variety of concentrica: Daldinia concentrica f. californica Lloyd.

Both D. grandis and D. concentrica are valid species names on Index Fungorum. It is a simple matter to tell these two from our local, usually much smaller, pimple textured crampball, Annulohypoxylon thouarsianum. But how about those two almost identical concentric ringed forms?

Here’s what Arora had to say in MDM: Concentrica is the European/Eastern North American form, with slightly smaller spores and a brownish cast to young fruit bodies. Grandis has larger spores and is blacker.

Genetically they are separate as well, according to a recent published article, summary here:

But to tell older specimens apart in hand, it’s all about location, location, location.

How does this differ from D. concentrica?
