could cause the fragile caps. Have you been getting the crazy sky water up in Gainesville over the past few weeks?

Yes, I noticed the long striations…

and that usually indicates a thin-fleshed cap. The marginal striations are short in levistriata. It could be that you have an unusually fragile specimen; however, some of the paratypes of levistriata are in my herbarium; and I saw that material fresh. These specimens were quite small, but had very short marginal striations none the less. So, you are quite right about levistriata being different in terms of the cap’s relative fleshiness. I have only seen the single Connecticut collection of sp-N50. I would not know what to expect in the next one I saw. I have an open mind concerning what we’ll end up with in terms of the specimen that you have found.

One of the things I was considering were some apparently rare taxa from the Carribean area (including Florida) that are largely white and yellow in terms of pigments (or lack thereof). I now think your material is probably not one of those.

Either Cristina or I will look at your material as soon as we can.

Very best,

thanks for the info!!
that species looks very sturdy to me in the pileus.
these specimens have a very thin, fragile pileus.
what do you make of that?

The last picture is a big help. The orange tints are not present & the volval material…

seems to have an olive hue.

The marginal striations are pretty long for A. levistriata, but the colors in the last picture really are a rather good match for that species. It will be very interesting to examine the material.

MO had a post in the recent past (by Brian Adamo I think) of something that looked very like levistriata from Tennessee.

We thought we had levistriata once on a COMA foray in Connecticut; but that turned out to be similarly colored, but with very different spores shape (if I remember correctly). I hope the Tennessee material can be found again and collected.

The CT material has temporary code number…“sp-N50.” I just checked the WAO page for that species and it is quite a bit like the present set of photographs.



Very best,

i’ll get them out tomorrow.
looking forward to the results.

Richard, is there a chance that you could dry this and send it to us in Roosevelt?

I thank you in advance if you can do so.

I think this could be something we don’t know or know but have never seen.

It looks like it might be relevant to the roseitincta-cruzii study that Cristina has almost finished or to comparison with some species originally described from islands in the Carribean.

Very best,

yes, the cap margin is striate.
the colors are very close to accurate.
i don’t have any melzers, atm.

Good grief!

Do I really see striations on the cap margin of this mushroom?

Are the colors close to accurate?

Are you able to tell if the spores are amyloid or not?

Very, very interesting.
