We dry them.

You can use a food dehydrator to do this, or your college may have a dryer for botanical specimens. Huge examples like this lepidella would need to be sectioned for thorough drying.

For small specimens in a hot climate, especially when I am “on the road”, I dash-dry fungi on the dashboard of my vehicle; gets pretty hot inside a closed car! You can also put small to medium specimens on top of a metal mesh greasecatcher (like for when you fry chicken) on top of a lampshade! this works very well, if you leave the light on until your mushroom is crispy dry.

Any moisture left in the fruit body will cause it to rot and mold, tho, so definitely assess the dryness before removing from light source.
Once dried, store in a ziplock, then get it to your local herbarium/mycologist pronto. Amanitas especially are great at absorbing water from the atmosphere, even after they have been dried. They put the mush in mushroom!

For at home study of fresh mushrooms…keep them cool!!! Wrap them carefully in waxed paper or put in tupperware lined with paper towels. Even then the decay process will occur, but just not as rapidly. Best to examine your material the day of collection. I also bring a cooler with me in my car, so those mushrooms get to chill ASAP. We have the advantage here out west, in that our mushroom season is primarily fall and winter and even the air temps cooperate with keeping our specimens cold. You hot summer collectors must improvise.

I’ll add this here hoping…

How do I preserve fungi. Plants…I press, Insects…I pin, Spiders go into 80% EtOH, mammals…study skins. Many of the fungi I see turn into slime after 2-3 days, great for flies, but not me

Yes that seems like a good fit as well, it would be nice to be able to see the base of the stipe/bulb.

I have a massive A. rhopalopus if you need a dried specimen, the thing is huge, probably would not fit in a large shoe box!

Did you consider A. daucipes?

Hi, Dr. W.

Did you consider A. daucipes for this one? The material seems youngish to have developed colored volval material and be A. rhopalopus, but…this is a crazy year…and there’s no dried material that could settle a debate….
