Cystoderma Granulosum?

[KeenTeen17]

Hi everyone. Is this cystoderma granulosum. I found it on wood chips in a conifer woodland about a week back. I find anything similar apart from C. granulosum in my collins. (To NickC: my philips book is on order)

I think you have a Psathyrella sp there KT.

oh right. I was hoping for a rarer species then

Psathyrella is a genus, not a species, so you may well have a rare Psathyrella, but I wouldn't get your hopes up in narrowing down to species

To add, I'm plumbing for Hypholoma marginatum. The stipe is characteristically marked with silky fibrils causing the 'snakeskin' effect and the Conifer log in the background would support the substrate.

I had this on my earlier thread today found in my local park under pine and beech..Chris had mentioned Hypholoma marginatum for this find...but wasnt too sure about the stem...

absolutely . . . this is classic H. marginatum spot on Nick . . . .

I'm afraid, KT that this is worlds away from Cystoderma granulosum which has a granular not a smooth cap, a distinctive ring zone, a white spore deposit . . . . look at your fungus carefully before going to the books

I would recommend taking shots in the field as you have, and then bringing some fruit-bodies home with you; do a spore print (that would rule out Cystoderma conclusively in this case); you have mentioned having a scanner - anything other than the larger toadstools scan very well and a side shot / gill shot under the scanner would make an ID much easier (the colour resolution of scanners is very good, better than any digital camera, no matter how carefully white balance has been calibrated)

if it really matters to you what a fungus is then give your collection a unique number, make notes of any features likely to disappear on drying and then carefully dry your collection and keep it dry in an old envelope or whatever; that way in years to come when you have assembled a good collection of books, and maybe acquired a microscope you can go back to it (all the features will still be there) and tackle it then

best

I would go along with that Nick, not a species I see awful lot of I must admit and I do get about a bit. Apologies to KT for the Psathyrella diagnosis but they catch you out now and again & again & again.............

thanks for the tips Chris. I actually do have a microscope but I don't know how to use it properly. Its a proper one that high schools use. My mums a technician so she got me one for xmas last year.

KT, you'd better have a go of it- so many people wish they had access to something so useful- you'd be silly not to try. You'll get the support you need from WABbers
