Cercophora on Hedera helix
Enrique Rubio, 23-01-2017 18:02
Enrique RubioHi to all
I would like to know your opinion on these brownish-black, superficial, ostiolate, up to 0.5 mm perithecia, when young covered by a whitish adpressed tomentum. No black setae, no other type of hairs. The asci have an echinulate subapical globule. The perithecial content is clearly yellowish.
Some idea for me?
Thanks again

Re : Cercophora on Hedera helix
Hola Enrique,
I have not much to say because I don't know this pretty Cercophora, maybe Andy knows it.
The wall structure is distinctive, with this salmon-coloured mid-layer (your image of the section is excellent). Is it also present on old perithecia or is it worn off with time?
Saludos,
Jacques

The ITS and LSU sequences suggest this collection is in the Lasiosphaeria lanuginosa species complex.

Cheers,
