That sounds good.

Please put the MO observation number (when there is one), data of collection, place and county of collection, and the name of the collector as you would want it to appear in formal credits on a slip of paper with each collection. Thanks very much for your interest in Amanita.

Very best,


Got 3 of them-

I’ll send them to you along with some other stuff I’ve been meaning to send once they’re dry.

I think for something this fleshy…

to have any chance of preserving the gill tissue for microscopic examination you need heat. The cap should be slice into rather slim “pie slices” (after you know that the creature can drop spores…and, hence, is mature). With limited space, you may want to dry only about half the mass of the cap. Like wise, cut the stem lengthwise a number of times and only try to dry about half of it (try to have a goodly piece of the skirt left on one or more of these stipe pieces). You need a window screen or a sieve to lay the material (of course you could buy a vegetable dryer, but you may not want to do that). A light bulb (100w or greater) under the aforementioned screen-like object can be your heat source. Any fans should move the area above the drying material. This will allow a column of hotter, dryer air to form rising from the light bulb and passing through the material you want to dry (which should be at couple of inches above the light bulb to avoid scorching the tissue). If you can do something with nonflammable material to increase the chimney-like aspect of the contraption, it will probably dry your material faster. All the material should like within the boundary of the “chminey”, and space should be allowed at the bottom of the chimney to allow cool area to come in around the lightbulb, get heated, and pass up through the material targeted for drying. When I was starting out I used to try to set up things to dry on the tops of lamps…tended to be too close to the bulb. The light will undoubtedly have to be left on overnight. There is an impact on the electric bill. Fluorescent bulbs often don’t produce enough heat; so this approach is most likely to work if you are still in the age of incandescent lighting in your home.

Anyway… It can be done without investing in a vegetable dryer. But someday soon there won’t be too many other options.

Very best,

I usually lay them on paper towels with fans on them. Is there a better way?

That would be very interesting.

I’m in a tight situation, I leave town for awhile early on the 7th. I’ll try to check in at MO while I’m away, but I don’t know what to expect regarding internet access. Are you familiar with drying chunky hunks like these guys?

I can head back there and try and get one.

I agree, Ham, it’s likely to be an Amanita.

My guess is that it is either in sect. Validae or sect. Lepidella. There is probably a tree that’s “close enough.”

It’s a couple of years since I’ve seen something like this. It would be useful to know something about the spores. Do you have the material? Could you dry it? or get a spore print?

Very best,
