The sunshine amanita is a bright yellow to orange mushroom that fruits in spring and early summer in mountain conifer forests, often at higher elevations soon after snowmelt and spring rain. Its common name comes from its habit of coming up in open, sunny spots rather than deep shade. Many caps are an almost fluorescent yellow, and a rarer form is apricot orange.
It was described as a new species only in 2005, by amanita specialists Rod Tulloss and Jan Lindgren. Before that it was thought to be a spring mountain form of the gemmed amanita. Mycologists suspect the name may still cover more than one species.
Like other amanitas, it starts life wrapped in a protective universal veil. On this species the veil leaves low, flat patches that seem to sink into the cap surface, leaving a whitish film that does not scrape away. There is a ring on the stem that often falls off, and a cup or ring of veil tissue at the base.
It grows with conifers. It is also seriously toxic: people who ate it have suffered vomiting, cramps, muscle spasms, diarrhea, hallucinations and drowsiness.
How to identify it
A bright yellow to orange cap, sometimes apricot, with low, flattened whitish veil patches that blend into the cap and leave a film that will not scrape off. The stem often has a fragile ring that may be lost, and its base has a cup-like or ring-like volva. It appears in spring and early summer.
Look-alikes
The gemmed amanita and yellow forms of the fly agaric are similar. On those, the warts sit on top of the cap and can be rubbed off, while the sunshine amanita's veil patches sink into the cap and leave a film. None of them should be eaten.
Habitat
Under mountain conifers in the Pacific Northwest and the Sierra Nevada, favoring open, sunny ground. It fruits in spring and early summer, often at higher elevations shortly after the snow melts.
