That is a nice site and your previous comment was very helpful. I had no idea there were so many species of Amanita!

Many genera are subdivided into ranks.

In Amanita, the rank below genus happens to be called subgenus. Not every genus has subgenera (plural of subgenus); for example, at present, the rank below genus in Limacella is called section. In Amanita there are two subgenera.

In Amanita it happens that the subgenera are divided into sections. There are seven of these (three in one subgenus and four in the other).

I’ve spent a little time trying to write a basic introduction to the highest level ranks in the family Amanitaceae (which contains two genera—Amanita and Limacella). This material is available on-line, and some effort was made to define unfamiliar words in the text as they come up.

Maybe these pages would be useful to you:


There are places in the text marked “…more…” which just means I’m not finished writing some parts.

I hope these short pages will help you a little.

Very best,


Is there a paper

I could read that explains the “sect.” designations? Are they like superspecies or tribes? Are they only in Amanita?

Thanks very much,


Thank you. [edited]

Maybe this is an Amanita. If it were an amanita, it would be a surprise for the sac to get left up in the air as you describe. Maybe it was a big ring. If it was a ring then this might be a pallid species of sect. Caesareae, maybe Amanita murrilliana; however, if it is not a ring, then, if it’s an Amanita, it would probably be in sect. Vaginatae.


I thought it

was the cup thingy like the white base cup in the foreground specimen, only split open.

Do you think that that’s a skirt…

falling down the stem on the specimen in the back?
