Help with this one much appreciated, on rotting Fa
Apothecia are sessile, ca 0.3 mm diameter; the hymenium is light brown with incurved margins.
Excipulum is a textura oblita, strongly gelatinised.
Hairs are 10-20 x 3-4 µm; very rough; with yellow pigment.
Asci are 40-45 x 5 µm, 8-spored, with a weak red reaction in IKI.
Spores are 5-6 (-7) x 2-3 µm, with 2 small oil bodies.
Paraphyses are ca 1-1.5 µm wide, with non-refractive contents.
The combination of characters indicate a Hyphodiscus. The closest fit seems to be H. hymeniophilus, but I'm not sure whether some of the characters (e.g. hairs with yellow pigment) fit this species.
I'd be grateful for any advice.
Thanks
Marcus
Yes, Hyphodiscus. But I am not sure if the spores fit hymeniophilus. The yellow pigment is not a constant character.
It is a very difficult genus!
Zotto
Many thanks for your reply. If you think it is a difficult genus, then there is little hope for the rest of us!
The other species I considered is the taxon you call H. "hemiamyloideus" but the spores didn't seem quite right in size and guttulation.
Marcus
was it impossible to see a reddish IKI reaction?
