The photographs (except for the patch with yellow surface)…

suggest collections similar to A. murrilliana that were brought in to the NAMA 2015 foray.

Very best,


It appears that this mushroom has a bulbless, totally elongating stem.

It appears there are remains of a saccate volva and a partial veil on the stem. Inconsistent with this information is what appears to be a patch of universal veil on the cap with a powdery yellow outer surface.

It would appear to be a species of section Caesareae except for the odd material on the cap. The yellow surface of the “patch” could be a different fungus growing on the mushroom’s volva. I have never seen this sort of thing that I can remember.

Did this material suffer heavy rains like those experienced during the NAMA 2015 foray? It looks a bit battered.

Very best,
