Next chance I get…

Well, now I know, I guess… I had gathered the last of these up, but they’re a bit moldy now. We just had a little rain, so maybe I’ll see more in the next few days. Fortunately, all my observations are made within a quarter mile of my front door, so it’ll be easy to keep an eye out.

COPIED FROM comment on 12131:

“You can dry on any surface with holes in it. The more holes the faster (& better) the drying. [A piece of stiff screening (metal or fiberglass), with or without frame is probably best.] A piece of paper or cardboard with lots of holes in it, with no frame at all, can be [placed] … over a light bulb while it is in a light fixture. [(Watch distance from hot lamp! Paper can sag toward lamp due to weight of specimen(s).] The fewer the holes in the supporting material, the more the specimen may need to be cut in smaller pieces to keep the drying as fast as possible. Fast drying is key to preserving the microscopic structures INSIDE the gills.

…[T]horoughly and crisply dried material can be put in a plastic or wax paper bag. The bag can then be placed in the smallest available cardboard box in which it will fit. Some …[paper] towels crumpled up or plastic peanuts that came with something you received by mail or UPS can serve as packing.

Place my address on a card in the box. [P.O. Box 57, Roosevelt, NJ 08555-0057, USA]

Seal the box thoroughly. On the outside of the box, address as you usually would. In a corner or on the back, write (it can be on a slip of paper taped to the box, for example), “Contains dried and disinfected botanical material for scientific study only. No commercial value.”

I hope that provides enough information. There used to be a “herbarium rate” for mailing such things by USPS [within the US], but for a package with only feather-weight dried mushrooms, there is now no difference from ordinary rates until the box has an awful lot of stuff in it (weighs enough). The video-tape-size box sold by the post office should work for you, if you don’t have a small box around the house."

Very best,

I’d love to, but I don’t have a dehydrator… unless there’s some other way. As I’ve said before, I’m quite new to all this.

pointed stipe base…

The fourth picture (with orangy area on cap) shows distinctly the typical inner volval layers cracking on the cap…evidence of for placement in sect. Amidella again. The patches are becoming brownish but not intensely so. I’m inclined to consider A. volvata less likely given the weak color change. The fact that you are repeately finding the stipe/volval base to be pointed reminds me of a taxon from the Gulf Coast region for which I have a provisional name only “sagittaria” [ see this ].

If you could dry some mature material for me (additional non-senile material regardless of level of maturity would be very much appreciated), I would much like to see it and will report on it.

I did cut the stalk in half, and the base terminated in a bulb of sorts… It was pointed on the bottom, as you can see (though not too clearly) in the third photo. In fact, on several of these (they’re abundant at the moment) the base was long and almost rootlike.

I have uploaded two more photos that may help, and will go back out at the first opportunity I get for a cross section photo. Just as a little note, in the fourth photo you can see a small patch of orange on the cap which is the reason I didn’t upload it in the first place… I’m pretty sure it came from the orange flag-marker I placed to help me find it again. Perhaps I was mistaken…

working toward possible ID…

I’d like to suggest that this species could be long in either section Lepidella or section Amidella. The floccose appendiculate material on the cap margin and the densely floccose upper stipe are seen in both these section. The cracking of a layer of volva on the is very suggestive of the latter. Of the species I know in Amidella, the one with the densest (most abundant) flocculence at the top of the stem is A. volvata. On the other hand, A. volvata would have had the exposed volval scales on the cap become distinctly red-brown during the period represented by theses photos.

Since there are a few species with limbate volvas in sect. Lepidella, it would help to know if the specimen was cut in half. If so, was the stipe terminated by a bulb below? Or was the base of the stipe about the same width as the visible stipe we can see in the photos?

Very best,
