Delicate bonnet fungus growing on wood.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
I have the same problem it is hard unless you familiar with the smell I have never sniffed an almond but would think some smelt of marzipan then (stupid)realized that's what marzipan is made of so,also had a Lactarius smelt of Bounty confectionery bar which is coconut so others have a smell aniseed balls,pear drops,nail varnish and some I just cannot pin point what it is.Sorry I cannot help with this ones as I find the group mycena rather difficult,hopefully someone else will know Flaxton is good on these so finger's crossed he will see them.
The descriptions of these two species (M. arcangeliana and M. filopes) are too close for me to have any sort of certainty! One of our experts on the day went for arcangeliana. But I think that was an educated guess.
On the other point, knowing chlorine vs iodine is tricky these days when you hardly ever come across iodine.

That goes for a few of these brown/grey Mycena. I almost always need to take them home for microscopy to be sure.
The more usual form of M arcangeliana has a smoky grey look to it.
