for working up this collection. Delighted to hear that you managed to eke out some good info from the damaged material. The postal employee flattened the envelope against the countertop before I had a chance to stop her. I should have used more careful packaging from the start.

These certainly looked like the online photos of P. hercules. If I run across this again, I’ll collect and preserve.

I scoped these, the collection arrived smashed into many tiny bits, however I was able to find a gill fragment full of angled spores with an eccentric germ pore and the cap discs are still intact allowing me to confirm there are no setae on the pileus. This implies this is related to the other Parasola species, at first I thought maybe P. hercules due to the small pale caps and widely spaced gills, however the spores are far too small and with the wrong shape. The spore shape and size is closer to P. leiocephala with the apical papilla, however I think that species should be larger with more densely packed gills?

So perhaps this is undescribed? Or maybe there are some more Parasola species described that are not included in this key? http://www.grzyby.pl/...
More info and micro pics to come.
