The problem

is that I don’t know exactly what is “growing in association with”, if it means it is over the pyrenomycete, it’s not. They just co-exist in this piece of wood.

these are or are not growing on/in association with a pyrenomycete?

but those referred genus are macroscopically different. It could be another sp of Bisporella yes. I was reading now about Bisporella sulfurina http://www.mykoweb.com/CAF/species/Bisporella_sulfurina.html and its association with pyrenomycetes, that I observe on this dried exposed root – some sort of Eutypella – though they are not on pyrenomycetes, and the diameter that is less than 1.5mm, makes possible to be this specie, I think.

and each one of them

should be changed to reflect that. I will be the first to admit that I’m not qualified to go into much detail on these. If you are interested in getting a species ID, AscoFrance would be the best place, but microscopy will almost certainly still be requested.

some other possibilities include other speices of Bisporella than B. citrina — which is erroneously listed in many NA guides as the only yellow cup fungus (not unlike Scutellinia scutellata) — Phaeohelotium, Hymenoscyphus, Calycina and Calycellina. I will try and find more when I’m next near my library.

there are lots of observations with that title and without micro. Anyway, can you tell me other look alikes?

but it could also be dozens of other yellow cup fungi. microscopy is the first step to an ID.

Bisporella citrina?

Could this be B. citrina?
