When: 2010-08-01

Collection location: Calhoun Co., Michigan, USA [Click for map]

Who: Charles Seltenright Sr (Shroomin Yooper)

No specimen available

Large Yellow Dry Cap,Flesh soft,very light blue staining when cut although not all specimens stained ,cap bruising brown-red,stem color is red.Found fruiting in large numbers in mixed pine-hardwood forest during early August.Please ignore date on pics camera setting was off.
These were not Bi Colors but were growing among Bi-Colors,Bitters,Badius,Old Man of the Woods,Russeli’s,Frosts and others in the same woods.I removed the pic that was in fact a Bi-Color and added a couple more.There were too many growing together with the same characteristics.I have never seen Bi-Colors fade to yellow all over as these were.They were fresh and could of been eaten not aged like color fading might indicate.Reminded me of a Huge Sullius at first but caps were dry as noted.Im searching for my notes on spore color and shape.

I know longer have the actual print but my notes from doing several different prints have them as olive-brown(the same as bi-color).Thanks all

You are absolutely right!!And a huge thanks to Noah(amanita)for recognizing it.I really never thought of it as possibly being older bi-colors cosidering the hundreds of them in that woods.Thanks again both you guys for your help.

proposal was not mine. It was Noah (Amanita virosa) who first proposed this species name for this collection.

I found a couple pics taken in the same area that would actually make Daves ID the one of choice.Although I havent found the notes on this yet I would have to agree with him.If you look close they seem to be mixed species or the same species of varying ages.Thanks Dave for your input,this Bolete has bugged me since finding it.

is fairly common… at least it is with the ones I find here in PA. To me, these look like bicolor, except for that the photo of the cut cross section appears to show white context… maybe because it was an indoor shot or with a flash?
