the rest of the identification relies more on the microscopic features… but anyway was a good learning exercise..

Oh, well there is some more info…

That gets you a closer. Not viscid knocks out C. mollis, so it isn’t that. (Didn’t really look like that either… that one usually is “fatter”.) Not hygrophanous knocks out C. applanatus, so that is something. But with the white on white still gets you C. cesatii or C. amygdalosporus/vulgaris/caspari. Not to mention other options… but closer!

‘Gills: Radiating from the point of attachment; close or nearly distant; whitish, becoming brownish in maturity
Saprobic; growing gregariously or in overlapping clusters on sticks and small logs of hardwoods or conifers’
Quoted Mushroomexpert

Not hygrophanous
Fine white fibre
No stem (at least in the ones I found)
Brown spores
Not viscid

Oh, ah, well there you go…

See you do have some notes. It is good if it is a new obs. from a new area to put in a note on the sources used when finding the name. Like MushroomExpert.com in this case.

Yeah, well, he only sites a few species there, and this is one probably only from the east coast of the US, and was published 60 years ago or so. You can look up more about it here:


But you probably don’t want to be that much of a Crepidotus expert… plus the species that over-lap with Europe were all re-worked in an Italian book that came out a little over a year ago.

It looks like C. vulgaris is similar to what I’ve seen in CA, you can see that here in one of my obs.:


And some micro-details here:


Which looks pretty good for Michael Kou’s C. vulgaris. (Although I seemed to get the punctate spores a little more clear.) Except in the recent work, this was all synonymized to Crepidotus caspari var. caspari, so there is yet another name for you.

But that still doesn’t help you, you are too far away, so who knows. Some other white Creps:

Crepidotus cesatii — http://mushroomobserver.org/25610
Crepidotus applanatus — http://mushroomobserver.org/19277
Crepidotus mollis — http://mushroomobserver.org/45159

Just to point out a few… you can click around on photos here to see what else might be possible.

Don’t worry about the microscope you can get pretty far without the microscope, and that is how everyone starts anyway. But for little stuff like Creps it can get hard with the scope, and uncertain. But lots of big and colorful stuff you don’t need the scope really.

For Crepidotus you need to know how fibrous is the cap, viscid or not, hygrophanous or not, color of cap, and color of fibers on cap. Along with the growth on wood, brown spores, and laking stipe and all that.

It would be nice to get a chart or something to help with beginners or in general on what features are important for each genus to help get to species. I thought it would be good to try and put that together…

Anyway, sorry, I’m sure that is way more that you wanted to know here…

This is the first season of my shrooming.. :) explains my being overenthusiastic.. But the way I am working is to take field samples and to search through the keys.. for the features I can identify macroscopically.. I do not have a microscope.. I’m using the references mostly through Mushroomexpert.com (this one’s mentioned there).. and a few other sites. Yes there were more brown Crepidotus next to where I found these.. in fact Thanks for mentioning that.. But yes you could be right that it could be some other white Crepidotus If you can give me some more macroscopic pointers.. I could go back and verify them…

No, notes on the name…

Well, yes, those are more notes on the obs. there. But that seems to just get to Crepidotus (mostly…). More notes might be is it viscid? hygrophanous? how fibrous the cap surface? If you don’t have a microscope, then we get into other features…

But I was wondering about the name C. vulgaris, what brought you to this name, compared to say another Crepidotus? I’m not sure I know that name, at least off the top of my head I don’t know what features would make up that name. I was wondering if you had some notes on what makes you use that name. Is it something common in your area/season? Are there not many Crepidotus species there?

Any notes on how you got this name, compared to other names?
