Summary: oh my :)

So the mushroom picker me…has no idea what this beauty is.

But to further complicate or help…I did find another of these at a higher elevation and in thick Madrone leaf duff.
I will upload a couple of new shots that may be helpful.

For all of the images I have of both finds feel free to view them at

Who is interested in a sample of this little shroom to help properly id it?
I’m game for trying to help with this but have no idea what I’m doing :)

Summary: yay! company for comatus

glad to hear it’s not by its lonesome; the vast majority did get moved out of the genus.

Summary: Coprinus sensu stricto

There are actually a number of species in addition to C. comatus still in Coprinus. MykoWeb has a page on one: Coprinus calyptratus (= Coprinus asterophoroides). This page also mentions C. xerophilus.

Based on the the Pacific Northwest Key Council key for Coprinus, there are several others in Coprinus ss. (formerly Coprinus Section Coprinus):

C. arachnoideus
C. alnivorus
C. spadiceisporus
C. umbrinus
C. roseistipitatus
C. colosseus
C. palmeranus

The key presumably provides reasonable ways to differentiate between these. The text on the site also mentions Coprinus sterquilinus which is not in the key, but was one of the species included in the DNA anaylses which came out with C. comatus. I have no idea if the other species mentioned above have actually sequenced or even checked for the macroscopic features of Coprinus ss. to ensure their membership.

Summary: small fungus, big controversy

I know that we can only work with the keys that we have, and no document will cover everything, but…has there been any work done in depth on CA “coprinus?” Can we assume that our mycota is identical to that of Europe and Hawaii (an assumption that has let us astray in the past)? And despite the beautiful work done by the late mycologist on his Coprinus website, where is a list of those current names? Apparently, there is now only one Coprinus species…comatus.

Summary: without scoping the spores, it’s a tough call.

our collector claims that he found it in grass, which indicates plicatilus.
if he didn’t save it (and what’re the odds, with an ephemeral shroom like that?)and doesn’t scope it, we’ll just have to endlessly conjecture…
but we certainly have the tools for future coprinus (sic) in hand/under scope IDs!

Summary: any book identification recommendations?

Matthew Keirle says “Parasola leiocephala closely resembles P. plicatilis, but is readily distinguished in that it has significantly smaller basidiospores that exhibit a more consistently central germ pore and by the fact that it is found in soil associated with woodchips in parks, not in grass.” Parasola plicatilis seems to always be in grass.

Summary: Parasola sp.

As Nathan points out, we don’t have a good key for these ephemeral little guys, at least at this point in time. Re: Darvins comment, Mendocino Co. is a mite far out of the SF Bay Area circle, even if you draw it widely, as I am wont to do. Parasola plicatilis and leiocephala are only separable thru microscopic means. I’d call it Parasola sp.

Summary: New id, but no good books yet…

Just wanted to let you know that some new proposed names have been made for this observation.

As far as I know there aren’t any good books out yet for the US that use the new names for Coprinus (in the broad sense). There is the paper by Redhead et. al. in Taxon discusses all of this in detail.

i really appreciate all the help

Summary: Looks more like a Parasola

Parasola is a relative new genus (2000) that is one of the 4 genera that Coprinus has been split up into based on molecular data. It is distinct in that it unusally lacks a ring and cap ornamentation, has more widely spaced gills than the other species and tends to be extremely ephemeral. Given the photos, I would call it Parasola plicatilis.

See Tom Volk’s discussion of Coprinus comatus for the fundamental details on the breakup of Coprinus.
