If it doesn’t have a carrot-shaped bulb, the probability that it is daucipes

falls precipitously.


The volval material on the cap of daucipes is quite variable in appearance. The orientation of the cells of the volva is in rows perpendicular to the cap surface. They can fail to break apart (in which case you get a patch like a sheet cake) or they can break apart a great deal leaving a mass of thin needle-like warts sometimes curving so that they touch at the tip. They can produce intermediate shapes. For more constant characters to help you along, you need to be able to see the root, pinkish staining of the warts and bulb; and, often, there is a felted ring around at least part of the stem base at the top of the bulb. (This ring is the remnant of the universal veil that was wedged between the bulb, stipe, and the tips of the gills during development of the mushroom).

So we’ve gotten to development. A big topic in Amanita. You way want to read what my son calls the “about pages” on the www.amanitaceae.org website. I suggest these two for starters:


When and if you feel like it, there other pages to which those link—for example an explanation of the sections of the genus Amanita. Allow about 15 minutes or less for a page. Most of the terminology is defined on the page; so you don’t need to go to a glossary. :)

Very best,


I love these big ones

They are so much fun to road spot. They almost always have a skirt hanging down, but sometimes it decays.

They often look like dumbbells before they fully mature and the bulbs are exposed.

Roody has a photo of the A. daucipes “carrot foot” that throws me for a loop. Huge patches and lots of dark areas , plus a carrot-like base that I’ve never seen on any of these.

once again fascinating stuff! Thank you!

I’m trying to imagine the bulb…

I think that (at least in second image) the species depicted is Amanita daucipes.

Amanita cokeri has a ver persistent ring and larger warts:


There are a lot of species of Amanita section Lepidella in eastern North America. Many of them have flocculent material covering the stem. Amanita cokeri does not have that characteristic.

Very best,
