well beyond maturity. It was found between two closely-spaced houses, which may have protected it from rainfall-erosion. Also, the weather this past month has been mainly hot and dry.

Up until last year I had not ever run across Pisolithus. The ones I found last year were smaller and not nearly as mature, obs 177272 . Not in the same location as the large one seen in this obs.

I was not aware of this in the east

but I can see on the occurrence map that it is not uncommon.

There’s only a tiny layer of peridioles between the stem and the spore mass. All the tons of Pisolithus I’ve found have substantial layers at this stage.
