both orange and yellow forms represent aprica.

an amanita with a range stretching from BC down into the Sierra.

It’s primary etymology is in reference to sunshine, not an orange color.

From the original publication by Tulloss and Lindgren:

“Sunshine Amanita”
etymology: apricus, growing in the sunshine, exposed to the sun, sunny; because of the species’ being found most often in places exposed to direct sun and because of the [sometimes; DV] bright “apricot-like” color of the pileus."

Cap description: “bright yellow to egg yellow to lemon yellow or bright orangish yellow, occasionally orange”

The most common form of aprica in both the PNW and CA is that bright day glo yellow. Orange forms (apricot colored) are more uncommonly seen. A casual perusal of images will show a predominance of yellow forms throughout its range.

is that genetic evidence shows a second taxon represented by these bright yellow (less apricot-colored) montane Amanita.

Sometimes primordia can form in a dry period and you only get to see…

the amanita when a rainy season established itself again.

This comment might also apply to the possible ___vernicoccora__ observation that Christian put a name on a little earlier today.

The frosty surface between warts on the caps in this observation are very typical of aprica. This is due to pileipellis holding fast to the base of the volval warts instead of gelatinizing and letting the warts slip around as they do on the surface of many amanitas.

Very best,

Rod
