Observation 47277: Pluteus petasatus (Fr.) Gillet

When: 2010-06-10

Collection location: Yosemite National Park, California, USA [Click for map]

Who: Erin Page Blanchard (CureCat)

No specimen available

This is one of the few things I collected for the Yosemite survey that did not make it back (deteriorated rapidly in my tackle box). Unfortunately, I do not know what it was. It seemed almost Pluteus like, but the lamelle were so unpigmented that I have my doubts.

P. petasatus looks good. The crackled center of the cap is really indicative. Thanks for pointing me in the right direction, Dave.

Thank you for the explanation, Debbie. You summed it up well. If you collect (very) small mushrooms, they just get thrashed and dried up in bags! Also, I usually put a paper towel on top of the tackle box, between the lid and the containers. It soaks up excess moisture that may otherwise condensate on the plastic and drip onto the mushrooms, causing them to rot very quickly.
And yeah, I use wax paper bags for medium sized to large mushrooms, and brown paper bags for the really big mushrooms.

If you are not into collecting little tiny mushrooms (most people are not), then there is no need for a tackle box…. But all of my mushroomer friends have tackle boxes, ’cause we love the little stuff.

Oh, and considering that we were out hunting in the woods for 4 days without a dryer or a cooler, it is kind of a miracle that only three things rotted! And yeah, they all went in the fridge or dryer as soon as we got back.

how did I miss that third photo??

Those gills do look like they are working on being free, so Pluteus petasatus is not a bad guess. Doug collected P. petasatus in Yosemite that looked a lot like this, also with pure white gills, a few days before you made your collection.


tackle boxes work really well for small specimens here in CA…

mostly because our season is in the late fall and winter and sometimes early spring, when temperatures are cool.

but if you leave your tackle box in a hot car, or in the sun, or the temperatures are unusually warm when you are hunting, then yes, your shrooms might just dissolve. but that would be true for paper bags as well…yes, paper is insulating and breathable, but even it has its limits…

even some of the easterners use tackle boxes to collect. the stiff sides protect delicate fruit bodies.

I like to use a mix of tackle boxes for small things and waxtex for larger ones, and I rarely ruin my shrooms, but it depends on the genus as well as the age of the specimen. also, as soon as i return from the field, my boxes get refrigerated, or put into a cooler.

I find lots of Pluteus with gills

that are pure white; not uncommon with P. cervinus (here in eastern NA). One Pluteus species for which the color change is relatively slow is P. petasatus.

Tackle Box?

I would think a tackle box would make the specimens you collect turn to mush faster than other containers CC, maybe go with paper bags instead.

Buy a large bag and fill it up with paper bags. That way each mushroom you pick gets its own little chill chamber. I have worked with some rather old Amanita material and I know that if it was in anything but a paper bag it would have turned to mush before I got home.

You can lay the paper bags in your car and if its sunny out by the time you get home the specimens will be dry, or drying. I notice a few other people use tackle boxes, why? I am curious about this.

free gills???

looks more trich-like to me, but no way to really tell now…
