Growing on fallen Willow
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.
If you had said you had just found this I would have agreed with abramsii as it is often one of the first Mycena to appear each year and it is on the right substrate. Without resorting to a microscope its defining macroscopic feature is the watery juice which comes out when you break the stem. Did you notice this?
I am new to fungi was as much interested in seeing them and photographing them as a record. It seemed a shame to damage them. There were only those to and they were well shaded. A little further along there was some Honey Fungus as well. I will put up another picture showing a larger part of the log
A photo record and leaving them for someone else to see is good and we can say for certain they are Mycena. Unfortunately that is as far as you will often be able to go with certainty without disturbing them, especially the Mycena.
