The fact that the base of bulb was located and can be clearly seen as covered…

with soil pretty much eliminates Amanita magniradix as a possibility…leaving A. rhopalopus. I’m going to get this under the scope this afternoon; however, spores often become distorted and abnormal in other ways when a specimen gets hit by the yellowing syndrome; so I don’t know what kind of results I’m going to get from the spore measurements.

Very best,

Rod

Thank you both

Let me know what name you finally put on this one.

Hawn Park has a great variety of Lepidellae

Thanks Patrick,

This material has been received and accessioned to Rod’s herbarium. He is planning on measuring the spores to determine which species this specimen is in the A. rhopalopus group.

This is very typical of the yellowing syndrome.

I have never seen the yellowing syndrome on this species (which I think might be A. rhopalopus).

This set of photographs is very nice documentation of the stages of development of the syndrome and its effect on the fruiting-body of an amanita.

Very best,

Rod
