Thanks, It looked the same after a quick glance, but different if really looked at. My mistake.

is “remove images”.
Click on that and then click on the circle for the particular image you want to remove. Click on “remove”.

I’ll delete the suspect one.

I’ll delete the suspect one. Well, I would if I knew how.

The mushroom in the second photo would have had to have lost its partial veil to be rubrovolvata.

Very best,

The second image is probably a distinct species and not in sect. Caesareae.

It lacks a ring on the stem. It is likely that there was no sack-like volva on the base of the stem and that the species belongs in section Amanita. Possibly, the specimen could be assigned to A. rubrovolvata or something similar. That species has been reported from Yunnan and has a range extending at least from Japan to the Himalayas (e.g., Nepal).

Very best,

Amanita hemibapha has a cap with a red center and a yellow margin.

Recent collections in southern India conform with the type and the watercolor that was painted of the type. The type was collected in Sri Lanka in the 19th Century. More information is here:

http://www.amanitaceae.org?Amanita%20hemibapha

A number of varieties of hemibapha have been named; however, recent molecular studies indicate that obvious macroscopic color differences combined with differences in spore size and shape are rather good at separating species that are supported by genetic data. So varieties that are not raised to species rank at present may be proposed as species in the not too distant future.

This mushroom could be Amanita hemibapha var. ochracea, which was originally described from Yunnan and Sichuan Provinces.

Nice photos.

Very best,

Rod Tulloss
