Many dried specimens now, let me know if anyone wants to do a microscopy ect.

Summery looks great.
I will go back and collect as many specimens as I can.
Heres a macro summary.
Pileus 3-4.5cm
Lamellea crowded and adnate
Hygrophanous cap drying to buff yellow/gold
Stipe 10-15cm long with striations running the length
Olive color abrupt base.

Just to sum up:

Ok, so a rough summary description would be:

apr. ave. spore size 15.5 × 8.2, from 2-spored basidia. Lecythiform caulocystidia and cheilocystidia, ave. capitulum size 4.3um. Bulbose base. On small woody conifer debris.

Is that about right? In terms of new species, I think Conocybe are so poorly studied that there are plenty of new species to desc. really. Except it would be difficult, since there are so few sequences, even from Europe, at this time for comparison. And the species tend to appear so randomly and rarely in such small collections, it will take awhile.

FAN6 has keys for Europe, I’m not sure there are any as good for North America, so maybe it could be undescribed? Douglas Smith might know more, you should message him if he doesn’t see this observation. Either way, please dry it out and save it with the MO observation number.

Undescribed species? Let me know if you need any more information.

There all had a bulbous type base, definitely no rootlike structures…

Using Flora Agaricina Neerlandica vol 6 and the information you provided, this seems to key out towards C. alboradicans, which should have a long pseudorhiza…

They were two spored basidia.
I checked a few of them 4.3um is average for the capitulum.
average less than 5um for sure.
I dont have ammonia…
Ill add a pic of a couple.
Ill have to start measuring more features…

Is the basidia mostly 1 and 2 spored or 4 spored? How wide is the capitulum on the cheilocystidia? (The little ball at the apex of the cheilocystidia).

“Cheilocystidia with capitulum 4.0–8.0(9.0) μm broad, on the average over 5.0 μm.” or “Cheilocystidia with capitulum 3.0–5.5(6.0) μm broad, on the average less than 5.0 μm”

Do you happen to have ammonia?

Not saving any of them, I have lots of microscopies to do lately getting lots of stuff sent to me. I feel bad though, when i put LBMs on MO they are usually just for pics for the shroomery. I cant imagine if I did a microscopy for all my LBM finds.

Can you scope this? Start with the caulocystidia, cheilocystidia, and spores. :)

Many of your recent lbm observations really need microscopy, are you saving them?
