Observation 45229: Gymnopus (Pers.) Roussel

Notes: This group of fungy were found in the hollow base of a dead tree. I have cleared away some debri to show the position of the fungi which were well hidden from direct light (and my peering eyes). The colour of the fungi was a light mauve, but I have had great difficulty in getting the colour to match what I actually saw. The colour seemed to change when I removed a group out into the light. (they lost some of the saturation and tended to go to an off white colour). Another problem I noticed was that when I view the colour of the fungi on my calibrated monitors, the colour is more saturated, than when I view them on the M.O. site on the net. The caps were dry and were about 2-3cm across The fungy was growing on wood.

of course, this could be something completely different altogether…

I gave the two possibilities equal weight, but my mind (and potential ID for this mushroom) remains open!

Keep throwing up these curiousities, Ian. Whether we can comfortably put a good name to them or not, we still all enjoy seeing them. Thanks for taking the time to look for and photograph the marvelous mushrooms of OZ (and if you like these, you should see Ian’s wildlife shots!!!).

Comment in ref. to Christian

Christian, the specimens that I posted were the closest to be reached in the cavity of the trunk. I may not have shown the other group of these fungi that were behind them. I did remove some of the fungi from the back of the second group (furthest in the trunk cavity), and they were of the same condition as the front specimens loaded. By this I mean that their physical condition was the same as the posted images. There were about 10 fungi remaining in the trunk area after I removed the small group to take a better photo. The area was not wet. all fungi were growing on bark, and there colouring was the same. There did not seem to be any fungi in the groups at a different stage of maturity. The stipes to me felt dry and fairly strong. The caps broke easily away from the stipes. The gills were soft and delicate. The caps in my images seem fuller, (if that is the right expression), and the stipes in my images seem to be thicker at the base than the “Prunulus” link that was suggested to view. Hope this is helpful. (looks like I have done it again.)

is not always ephemeral – especially considering all the forms that we lump under P. purus.
Some of them are kind of beefy.
See Ron’s observation here: http://mushroomobserver.org/image/show_image/65364?obs=28497&q=RMD
…for comparison, flip back and forth to the photo from this obs:

You can still see the hygrophanous fading ‘in process’ in Ron’s obs. My guess is that Ian’s specimens have lost full cap moisture completely, and become opaque, so the impression of delicacy is lessened. Roy mentioned that the ‘watery’ look is important for his gestalt sense of the genera – I fully agree.

Nonetheless, when I look at those first two shots, my gut instinct jumps strongly towards Gymnopus.

these don’t look ephemeral enuf to be Prunulus/Mycena…

and they reminded me right away of the pretty purplish Gymnopus iocephalus.

both stipe and cap look fibrous to me.

see Ian’s recent stipe close-ups.

It’s the texture

Ian that I can’t get a handle on (so to speak). It’s really nothing you can definitively show in an image, with rare exception. In Prunulus and Mycena the stipes are going to be more watery and, in my experince, get hollow pretty fast as the mushroom matures. With Gymnopus, the stipes are just tougher and stringier – which I know can be a hard concept to grasp – and can get hollow but not so fast. How’s that for a quantitative analysis?! Poor at best I’m afraid.
Pale violaceous Gymnopus species are few and far between (G. iocephalus in E USA for example). However, I know of a G. confluens-like entity from FNQ that is cyan colored! Not described to my knowledge.


Sorry again Roy, I did not cut the stipes. They were firm and held the caps whilst I moved them out into the light. Hope added image helps. KK

Good call

Christian – I was leaning toward Gymnopus but I can’t get a decent sense of the stipe texture.
