Scutellinia setosa?

M Jonathan, 28-10-2016 03:55

very small Scutellinia (2mm) from rotten Maple wood, near Ottawa ontario, 26 October 2016.

Spores smooth or very finely ornated, measuring 20-22-12-14u.
Ascus octospored, do not react with Melzer.
Paraphyse with orange content on apice, apex inflated, multiseptated.

Very similar to S setosa, but spores seem slightly larger than what they should normally be for this specie.

Furthermore, is it possible to get a culture of this specie? I would like to get DNA out of it.

Re : Scutellinia setosa?

How long were the hairs and were the spores described from a spore drop or just a squash?

Re : Scutellinia setosa?

for the plate on the original post spores come from a squash, however I took some more photo today of ejected spores, hairs measure up to 500-750u long.

Re : Scutellinia setosa?

Good evening, I could see your photos; have you tried instead to Cheilymenia?

Michel.

M Jonathan, 29-10-2016 21:28

Re : Scutellinia setosa?

Not too familiar with that genus, do you have a key you can send me?

I don't know if Cheilimenia can be found on rotten wood however?

Viktorie Halasu, 30-10-2016 17:26

Re : Scutellinia setosa?

Genus Cheilymenia has eguttulate spores, this should be Scutellinia IMHO. But I can't say more, never saw S. setosa myself.

Malcolm Greaves, 30-10-2016 21:45

Re : Scutellinia setosa?

It certainly looks like the couple of finds of this species that I have.
