in the Algarve, Serra Monchique, on old Xylaria cinerea on Acacia-logs near the ground in Eucalyptus-forest. First I noticed the yellowish color of the Xylaria and took a specimen. I show it first.

Re : nectrioid fungus on Xylaria cinerea - anamorph and teleomorph belonging together?
When looking more exactly I found older stromata of the Xylaria from the last year, quite strongly decayed and crumbly. On one of them I found some perithecia of a nectria-like fungus. I am not sure if it is perhaps the teleomorph belonging to the yellowish mould already showed.
The hairs of the "Nectria" are beautifully yellow and contrast well with the dark red perithecia. Unfortunately I found only few riep spores and no clear asci. The spores I measured 11-15/4-6. I am not really sure but perhaps the spores are longitudinally striate (as there were very few I am not sure if I am not talking about an optical artefact). The perithecia were mounted in KOH - and there was not decoloration, so no Nectriaceae. As the sample contains only of quite few ascomata I did not examine more perithecia by now.
Who does have an idea?
Yours, Lothar
