The bulb of the citrinoid taxa is soft…almost like a marshmallow…

and when you cut the bulb it smells like a radish or a “newly dug potato.”

Very best,

particles of volva. That and the shape of the bulb would support Eric’s suggestion. I have seen Amanita flavorubens washed completely white by monsoon rain in Arizona. So, it does happened….

Thanks for offering the specimens. We’re studying the rubescent taxa this year as well as the “citrinoids.” The material will be put to good use.

Very best,

the staining I’m seeing is more red in color. I wonder if these could be more faded A. flavorubens.

Wet and cool

It has been raining really hard for several days, with cooler temps than normal for the midwest this time of year. These are the only pictures I have. This specimen is being sent to Dr Tulloss.

doesn’t seem to fit A. citrina f. lavendula. Is that a limbed volva I see on some of the specimens in the ground? Do you have any more photos of the bulbs/volva? There does appear to be lavender staining on the cap. Has it been cold in Missouri? Interesting.
