is completely different and much smaller. In most cases in electric light you will not even see the fruitbodies on wood or other fungi (most of them are parasitic on pyrenomycetes). You need full daylight for detecting them (save Nectria cinnabarina and allies)

you mean to settle this debate once and for all? ;)

other wise…conjecture.

did you actually find a photo of Tetragoniomyces uliginosus? I couldn’t.

As to why this is NOT Nectria coccinea:

(from Swiss Fungi, Ascos): fruit body SCARLET with a DISTINCT PAPILLA.
glassy and translucent when fresh. when fruit bodies emerge from bark, they are bundled into small clusters; when they occur on decorticated wood, they emerge singly.

Nectrai coccinea are DISCRETE fruit bodies, each spherical to oval to pyriforme, not amorphous jellies in masses.

not sure what Jonathon is showing in his micrograph (conidia?) but Nectria has ellipsoid, septate spores, no conidia.

if i find this next year , did someone would want to scope it?

this could NOT be a Nectria.

will try to found it this year for more study.

aha! a tremelloid mycoparasite!

Tetragoniomyces uliginosus is a basidio, BUT it produces conidiospores (like those that you showed here).

You are absolutely correct that it isn’t Nectria, for lots of reasons.

Hi Jonathan-

I don’t have an explanation for you, but I agree it doesn’t look like Nectria. Check out obs. 67582. Looks like the same thing.

can someone explain me why it is nectria coccineus?

this is NOT nectria, it might not be fungal at all
