No specimen available

Good to find a Mycena that stumps the leading experts in Mycena in CA. Found these on a rotting stick, not far from the field center. The shape of these is more like tropical Mycenas I was told, and not like any in CA. I gave these to Brian Perry, and he put them under the scope, and told me “I got no where with them.”

He has dried these and saved them, and might do more work on them in the future.

Recognized by sight: These look strikingly similar to observation 47387, though I have no idea how many tropical Mycena spp. show similar resemblance. Just a thought…

Recognized by sight: A Finnish woman suggested this name for a collection of a similar Mycena that Christian Schwarz made in Washington state. A Fries name, so maybe originally described from Sweden.

Smith records it under the name Xeromphalina picta

which is now deprecated in MO. It is reported from Quebec (!), Ontario, Michigan, Tennessee and the Pacific Northwest. I would not be surprised if M. mamaku turned out to be a synonym.

Well, I tried to look up details on M. picta, and strangely I didn’t find anything… I looked in “Mycena d’Europa” Robich, which is a fairly complete looking book with 127 species in Europe described there. But there is no Mycena picta in this book…

I did see Mycena picta online here:


And seems to be the only species like it in northern Europe at least.

It is listed in Funga Nordica at least, and seems to be the only species like it in that source.

This is the observation that reminded me I had to get some images of M. mamaku because it looked so similar so I was happy to find the nice fruiting that CureCat has linked us to above, thanks CureCat.

M. mamaku is considered to be an endemic species to NZ so it would be interesting to see how close this collection is to those from NZ.
Here in NZ M. mamaku fruits exclusively at the base of the tree fern Cyathea medullaris and on dead trunks of this fern also, the Maori name for this tree fern is Mamaku.

That is the coolest Mycena I have ever seen!

I wonder if any similar collections have been made. Would have been neat to get some micro details.
