Thanks for clarifying that, Irene!
is a section of Entoloma, usually recognized by the particular cap (smooth, usually hygrophanous) and stem structure (striate), and has been used as a name of a genus by some – american authors in particular.
The same thing with Leptonia (polished or floccose stems and/or caps that tend to be more or less scaly).
DNA analyses has indicated that the traditional limitations of those sections don’t make them monophyletic, and they are, at least for the time being, just Entolomas.
I don’t know whats up with that…
Maybe it will let you if you suggest the Genus and Species together?
Oh well, I guess I’ll have to do some reading!
I was able to post Nolanea strictia
Nothing came up stopping me from that.
I asked if Nolanea was now in Entoloma but did not get an answer.
Maybe I’m wrong on mine, but it wasn’t corrected?
Earlier, I tried to suggest Nolanea as a possible genus but the site said it was depreciated?
I guess I will save Entoloma identification until I’m a bit more experienced.
Douglas, I agree that there are much more interesting genera to view under the scope.
Of the few that I’ve looked at, I’d have to say that I enjoyed viewing Pluteus cervinus the most! I can’t wait to find some different Pluteus this year!
Inocybe seem interesting as well.
Thanks for the feedback guys.
To pin down this kind of Entoloma to species, is like finding a needle in a haystack.
My guess is a Nolanea type with Mycena-habitus and without cheilocystidia – other species in that group are cetratum, vernum etc. (many of them with striate caps and papilla), but without very prominent macro- or microcharacters, I usually give up on them.
Well, I haven’t looked at that many Entoloma. They are traditionally known as not easy to deal with, even with a scope. If I remember right, only about 25% of species or so have cystidia, most do not. The times I have seen cystidia in Entoloma, they are rather boring, and just cyndrical, not much significance in shape there.
There is some stuff you need under the scope, but they aren’t the best. There are other genera that are much more interesting under the scope.
Thank you Douglas.
I didn’t see any cystidia.
Do Entoloma tend to not have these cells?
I found some different Entoloma just two days ago and could only find basidia on those specimens as well.
Those are basidia. The “prongs” are the sterigmata, the spores mature at the end of each, and the break off. Those are “4-spored” basidia, which is a taxonomic character in many genera (and not in others, depending probably on the whims of the mycologist). Some species have 2-spored basidia, most 4-spored, some 5-8 spored… But even in those you get randomly a few basidia with different number of spores produced, in a 4-spored species you will see a few 3-spored, and 2-spored basidia, but only a few (and maybe a few very rare 5-spored…).
The problem is when the basidia are young, and the sterigmata haven’t been formed yet, then it might look like a small clavate cystidia. But you can tell, because there are 100’s of similar basidia all smashed together on the gill. If they all look the same on the gill edge and face, then they are all basidia.
Can anyone tell me what the structures on the gill’s edge are?
They have four prongs at the apex.
One of them appears to have only two prongs, but if you roll the fine focus it reveals two more.
