Observation 34121: Coprinopsis P. Karst.

When: 2010-02-20

Collection location: Cannibal Gorge, Lewis Pass, New Zealand [Click for map]

Who: Jim Baltaxe (JimBaltaxe)

No specimen available

As a “newbie” (newcomer) to this field I am not sure of the identification, especially in a Genus this varied and sensitive to microscopic examination, but I am wondering whether the great physical distance and different habitat would be enough to suggest a possibly different species, or subspecies.

The only other reference to P. plicatilis is in the Auckland, NZ region, at a much lower altitude and much higher (minimum) temperature range, than this observation. It was spotted at about 850m in an area that gets very heavy frosts for at least half the year and high temperatures of mid to high 20s, centigrade, of course.

I would appreciate it if anyone could tell me whether this may be significant. If so, and this could be a different subspecies I would like to call it P. plicatilis robyni.

You got me! This one looks much more pale, silvery, and gracile then the C. lagopus I am used to seeing, but after seeing your photos and comparing a few other collections, I see what you mean!
Please propose C. lagopus.

CureCat I think we might have to disagree here Jim’s photo shows an old specium were the fuzz-like tufts have disapared. There are some better photos on my website http://hiddenforest.co.nz/...

Clive, it is not C. lagopus, that species is quite different, with a grey cap covered in very fine, practically fuzz-like tufts which are easily brushed away. The stipe also tapers gradually to a thicker base. C. lagopus is also larger.

Lesson in what to look for

Hi Curecat
Thanks for the opinion; I’m starting to learn what to look for in making an identification.

I’m happy to defer to those with greater knowledge of course

In that case it would wind up being Coprinopsis plicatilis robini, assuming that the case for a subspecies does stand up. BTW I am taking the opportunity to correct a misspelling in my earlier suggestion.

Coprinopsis sp.

Hi Jim,
I recognise this species, its very simlar to Coprinopsis lagopus but I am not yet convinced that it is this. I see from the back ground its likely to have been found in native forest (were C. lagopus is usaly found in woodchip). Its been on my to do list to exsamin both species to see if there is any diffrance but its just something I have not gotten around to.

The ephemeral, floccose patches on the cap remind me more of Coprinopsis.
