Recognized by sight: A difficult call here like all synnematoid without a suitable microscopy, however the habitat on tropical wood and a presence of a possible stroma at the base and a black stem with a slimy pale head hint toward that specie.

but new observations from field work this year are coming. once the material arrives, microscopy and sequences will (eventually) accompany them.

any micrograph?

It is not all days whe have to occasion to see those pretty cloud forest fungus…

having recently seen and scoped this sp.

several times, I feel confident in giving this observation the name F. wrightii. it is a much more common cloud forest species than previously thought.

that why i consider it an hard call

however this one is fairly distinctive as this is the only synnematous fungus (wich look like these) that I know of that have white head and grow on a stromatic base.

It’s funny

Two weights two measures … How did you got to genus here, or worse… to species? Thousands of organisms seem like these. No micro, not even references… whattttt??? :p

have collected this

several more times now in Ecuadorian cloud forest. the carbonaceous, black, pulvinate base is more more apparent in those collections. observations forthcoming.

Thank You, Jonathan

that looks like a real possibility. you are the first person to have a clue as to what this is. I continue to be grateful for your careful attention toward tiny fungi.

if you can believe it, these were among the easier subjects to capture. no bushwhacking required, just right there on the steps. in the absence of a macro lens, extension tubes are what get jobs like this done.

I wonder if it could be a calicioid lichen

Depends on the orientation of the plank — calicioids can’t survive being hit directly by raindrops, so they’re always found under leaning trees or otherwise well-sheltered situations (base of spruce and fir trunks for example).

Looks like this might be growing on top of a picnic table?

(Spectacular photos — must’ve been very difficult to get those shots. :)
