Herbarium collections

Martin,

The mushrooms (found by Christian Schwartz) were several days old when we returned from the Mycocamp and I finally dried them. I’m not sure if they will be usable, but will mail them to you next week.

We have another collection of the same (or very similar species) in the Herbarium, found by Joe Cohen a week earlier in a different location. You’ll get that as well.

Thank you for your interest!

How would you like to compare the sequence of your specimen with the one in my photo? I can’t guarantee delivery of that, but I do have the opportunity to do some limited sequencing. I have heard that Entolomas can be difficult to amplify, etc. but it is worth a try. If you have the time, please send to Martin Livezey, 10219 Parkwood Drive, Kensington, MD, 20895. Thanks!

Martin,

The dark gill edges are visible in dried material. I just added a photo, it shows them, though not quite as well as you would see under dissecting scope. If you would still like to examine this collection, I’ll be happy to send it to you.

Great shot!

1. What a great photo!

2. The specimen is preserved and in the possession of Sava Krstic. I will alert him by direct email (copied to you ) about to this set of Comments, and your interest in looking at these mushrooms. It’s best if you get in touch with him directly; if I’m in the middle, it will just slow things down.

Thanks Joe

I am fairly new at this, too. I have been posting to MO for over 3 years and I can tell you it is a great place to learn. Here is my attempt to do what I am asking you. It could be better; it was not shot in the heat of a foray. Even so, your species look sufficiently different to check out. If you still have them, I would love to take a look at them.

Less compression
By: Joe Cohen (Joseph D. Cohen)

Martin:

1. I replaced the photo with one having less compression. But I think it still doesn’t do what you want. If I look at it with a different viewer (I’m using Vista Previa), I see that the gills have definite dark edges. There’s something which might be serrations, but I’m unsure whether that’s the gills themselves or an artifact of enlarged square pixels.

2. No reason to trust me personally. I’m new at this.

3. I wish the photos at this Foray were generally higher quality (although the ones taken by Christian Schwarz are great). Moreover, even when the photos are generally good, a photographer who is inexperienced in identification won’t know enough to document some critical characters. I think we can easily improve the general level of quality, but I don’t know how to solve the disconnect between identifiers and photographer. Do you have any suggestions on how to handle this, or what to do when the photos don’t show what’s needed for a third party to confirm the ID? (Sometimes that will be a very tough standard to meet.)

I trust you and all that

and I know how hard it is to document a foray – but it really would be nice to have a sharp close up of the gills if you use this name. It is just part of the territory.
