Galerina??? growing in compost

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

Galerina??? growing in compost

Post by Bob Hazell » Sat Feb 23, 2019 10:45 am

This small fungus was growing in a large flower pot filled with compost in my Rugby garden (on 18th February). There were about 6 in all. All specimens were short lived. The smallest had a cap only about 0.5cm dia and the largest a little over a cm. Initially convex or umbonate they appeared to flatten with age. The gills are distant. The stipe was about 3cm and had a small ring. The stipe is a similar colour to the cap and has white fibrils. I suspect they are a Galerina species but would again welcome the thoughts of those far better informed than me.

Hi Bob

I would be looking at Conocybe, perhaps something close to Conocybe rugosa.

Cheers, Chris

Hello,

yes, its not a Galerina, but a Pholiotina (Conocybe subgenus Pholiotina), as you can see that the ring is striate. This is never the case in Galerina.

best,
Andreas

Thank you Chris and Andreas. In particular thanks for the explanation regarding the striate ring. I thought cryptic crosswords were difficult but fungi are in a completely different league! :)
Regards,
Bob

I have collected Pholiotina hadrocystis on a soil/woodchip mix in a town centre raised flower-bed, but you need microscopy to take these to species.

Thanks Chris for your thoughts. Certainly images of some Pholiotina hadrocystis that I have seen are pretty similar, but as you say without microscopy I am unable to take it further. I have done as Andreas suggested and recorded the images as Conocybe subgenus Pholiotina. Thanks for your help.
Regards,
Bob
