Observation 70427: Amanita pantherina sensu auct. amer. group
When: 2011-06-28
No herbarium specimen

Notes: I live in Portola, have found at least 4 Amanita aprica (possibly as suggested by Herman Brown from San Francisco Mycological Society) in our backyard. All have been in open areas, fully exposed to sun and under Ponderosa Pine and Black Oak, not Douglas Fir as described in several references. We are wondering about the toxicity level of Amanita aprica, as we have a new puppy who eats everything. We have never seen this species in all the years that we have lived here and assume the late snows and frequent rains have allowed new fungi to pop up that have lain dormant for many years.

Recognized by sight: brownish tones to cap in this aging specimen; sometimes hard to tell the two (gemmata vs pantherina) apart from just a photo.

not aprica…

annulus way too developed, cap color is wrong, warts are discrete, not grown into cap.

ANY of these species can be dangerous to a puppy, however. Puppies, like human infants, have undeveloped and somewhat unstable physiologies and can be more greatly affected than a mature dog. Frankly, it’s no picnic for a mature dog or cat) either. Bad news is that these mushrooms ARE attractive to pets and taste good, too (although good taste is not always a factor, as you dog owners know).

Best to keep your pup away from these…convulsions and coma are not a good thing for anyone, dogs included; some pups HAVE died after eating some of these muscimol/ibotenic acid containing amanitas. If it’s a pantherina, that would be the worst of the toxic amanitas in this group. Gemmata is probably the least toxic, and aprica somewhere in between. If eating one mushroom can adversely effect an adult human, imagine what it might do to a small pup!

This mushroom will not kill your dogs but might make them go crazy for a few hours.

Cut it in half…

A. aprica will usually have yellow-orange flesh near the apex of the cap. See here:


A. pantherina and A. gemmata won’t.
