Observation 134099: Amanita ameripanthera group

When: 2013-05-20

Collection location: Cowichan Lake, Vancouver Island, British Columbia, Canada [Click for map]

48.8304° -124.0439° 180m

Who: Clayton (MayDai)

Specimen available

Old growth forest, Tall Douglas fir trees where these species were growing the most and a couple Spruce trees with thick conifers on ground.
The majority or becoming eaten by the ground maggots? so i pick them before being destroyed.
Nothing done with Chemical test(Iodine test when i can.) No Microscopy. (So none can be given)

Has Warts/White patches on cap.
Stem bruises a tinge yellow after being handled a lot, The stem has a very distinguishable tinge smell, The cap has more of a nice caramel smell to it though.

White Spore Print, Didn’t come out prominent so i didn’t take a picture yet.
Dried specimens for feature ID upon request.

Mushroom cap seems to be white/yellow tan at birth to pale yellow and dark brown at maturity depending on lighting and weather conditions. If lighting is good it seems to stay the prominent tan yellow color.

I put a leaf over one small Amanita mushroom and it went mushy with decay and then turned dark brown on cap, bruising dark purple with rot after day two.

I have a lot more pictures of more specimens then i am posting now, If anymore info or pictures is needed i will help to the best i can upon being asked.


Had to be picked, Stems being eaten by maggots badly killing the mushroom it self.

Proposed Names

Recognized by sight: I Have seen Amanita muscaria’s in pictures as well as these A. pantherina’s, Also i have seen a really nice specimen of Amanita muscaria with my own eyes. was able to look at it closely to check the features of the mushroom.

I will save for a Microscope.

Thank you for the help, I will continue recording these species and others.
I will then return to the dried specimens after i purchase a microscope and further research and post my results.
I have been here and there on your site and will continue using it as well, talk soon.

You’ll find a lot of supporting information about microscopy, photography, field notes, etc. (focused on Amanita) on the www.amanitaceae.org (WAO) site. You can use the email feature of MO to write to me if you would like a PDF of a workbook with a lot of methodological points about using a microscope with Amanita. Also, On the top left of any taxon page on the WAO site there are a list of “teaching points.” These cover several points important to proper measurement of spores and how to summarize and record the data you collect on spore size and shape.

I suggest that, if you can, you save up for a microscope that has an oil immersion lens and has objective lens that have planar focus (i.e., everything in the field of view in a given plane is in focus at the same time.


More than just one Amanita Species.

It seems i picked more then just one type of Amanita sp. Maybe even two or three types.

Thanks Observer for the direction pointed, it seems i have a very close resemblance to three of the Amanita sp. “Amanita umbrinidisca” i think or close.

But the Pantherinoides i am not sure of since the patches don’t fall off unless washed off. Viscid cap though when wet, so it’s hard to tell, I need to invest in a Microscope.
