The photos of Horak’s collection really bridge the gap between this specimen and more typical
Pseudobaeospora. For someone who has developed an affection for the genus, these colors are really a treat! I feel confident enough to change my vote now, but I am looking forward to more microscopic details.

By the way, I’m more skeptical than I was even for this collection about the potential identity of the collection labeled 68/255. Looks staturally very different.

Thanks Christian, I was hoping you would see this, I noticed you have looked at this genus in the past!
There are some not so good micrographs from a later collection of this species here.
The cells were very small and I was unable to get any really good images at that time and I didn’t have any Meltzer’s reagent, I now have the 100x oil immersion objective and Meltzer’s reagent and can make a fresh collection today so I’ll take a closer look.
The reason for this naming was due to E. Horak’s image at Landcareresearch, the last two images on the page in the link below are the same species that I have here, I’m not sure how certain he was of his identification.

I could see Pseudobaeospora

But the colors and stature are different enough that I’d really need to see some micro to be convinced. Particularly tiny spores that are about half dextrinoid. That alone would clinch it.

Don’t suppose any microscopy ever came about for this mystery find… Few of your observations make their way here with no proposed names, and even fewer remain that way for so long.

Hygrocybe sp.

It does not look like any Hygrocybe that I have seen. just not the right look to the stipe. On the other hand I don’t recognise it as anything that I have seen before ever. Sorry I can not help.

was a guess, as you say this mushroom has some unusual macro features, especially the pseudorhiza and orange latex, I will add some microscopy soon!

I don’t think this is a Camarophyllus species, not with that adnate to sinuate gill attachment!
Maybe Clive knows?

wow, latex?

this seems more like a camarophyllus than a hygrocybe…but that latex is perplexing, and a pseudorhiza? can you collect these and scope ’em? may be something else entirely, but what, i have no clue.
