Projects regarding citrinoid, rubescent, and solaniolens-like amanitas in 2013.

This looks like the pinkish staining (see center of cap) entity that David W. has called “solaniolens.” Some photos of David’s suggest very strongly to me material that was first sent to me (or shown to me fresh) by Walt Sturgeon a very long time ago…and that I’ve called “sp. O2” in keys and correspondence. WAO doesn’t have a page for it at present.


An invitation

I just wrote to David this afternoon (and also posted recently on MO) to tell him that I have a very kind offer to try to work with genetic analysis support on three “grouplets” of amanitas…largely based on well-documented and well-photographed collections MADE THIS YEAR.

This is not a party with a restricted list of invitees, but it is necessary to do a little work with camera and pencil and paper (or email or MO or…etc.) in order to be involved. The entry fee is that collections must be supported by good photos when possible and (hopefully always) by good field notes. Field note forms can be downloaded from the WAO site. Click on the blue navigation bar (upper right of every taxon page on the site) labeled “Form for Taking Notes on Fresh Collections, with Samples.”

The three “grouplets” are as follows:

1. “It looks like ‘citrina’ or citrina f. lavendula.” This group includes very pale capped specimens to which the previous sentence would otherwise apply. At the moment we have evidence for three taxa of this group in eastern Canada, eastern U.S.A., and eastern Mexico.

2. “It bruises like rubescens.” No restrictions on cap-color in this category. This category is not restricted to North America; however, we realized that it is improbable that we can cover taxa outside of North America with large numbers of collections when limited to one collecting season.

3. “It looks like solaniolens.” This category is restricted to the Americas north of and including Andean Colombia. We think there might be two or more taxa here. If there are two taxa, one may be quite dark (my “sp. N20” not on WAO), and the other may be more pallid with pinkish bruising (my “sp. O2” not on WAO). Both have brown or gray “radial hair” on the cap (that is, the caps are virgate).

Note all the species of interest are in Amanta sect. Validae.

Please note, again: It is important for separation of the taxa (or not) that we have good sets of field notes and photographs for the dried collections sent to us for use in the project.

To optimize the likelihood that DNA can be extracted from your dried material please use a dehydrator at a moderate temperature. It is important to keep the material as dry as possible while it is in your hands. DNA can be difficult to extract from recent collections if they were exposed to high humidity after drying.

For more information, please feel free to contact the project folks through the “contact us” feature on the WA0 website.

Very best,

I do have this one dried out. Only a single specimen I’m afraid, but a complete one. There were a dozen or so in the immediate area. I will send this along with another one or two I have lined up for the good Dr. From Tampa up north in Florida does seem like a hotbed of Amanita diversity. It’s glorious! Thanks for commenting.

Josh, if you preserve this specimen…

I believe that Dr. Tulloss would like to look at it. Seems to me that A. solaniolens is a relatively new name. A collection from Florida may provide good info about NA distribution. Looks like my concept of solaniolens… thin stipe, innate radial streaks on the cap.

I have e-mailed Dr. Tulloss about some of these very interesting FL amanita collections that have recently appeared on MO. He is apparently currently very busy.

match very well with the macroscopic description of Amanita solaniolens except for the potato smell, but these were found in the midst of some saw palmetto under live oak in Florida! I saved a specimen which is up for grabs.
