Hi Enrique,

Did you get anywhere with this? It looks related to Lichenopeltella alpestris s.l. found on Plagiochila asplenioides (see Marsh et al., 2010) but is clearly distinct as it lacks the papilliform cells on the ostiole neck and the asci are 4-spored.

Hi Georges.
Nothing. I had even forgotten about it. But since you're talking about it, do you have a description of this fungus you're talking about in  IMI Descr. Fungi Bact. 174(nos 1731-1740): [2] (2007)?

Hi Enrique,

I only have this https://karstenia.fi/ascomycetes-and-anamorphic-fungi-growing-on-plagiochila-hepaticae-in-finland/ - I have collected this on Plagiochila asplenioides and once on dead Polytrichum commune antheridial cups. We think it may be colonising the cuticle, perhaps with a broad host range.

And a documentation of my collection here https://fungi.myspecies.info/all-fungi/lichenopeltella-sp-p4998 - it is distinct from the true L. alpestris.

Hope this helps,
George

Thank you, Georges, but I don't think that my collection can be assimilated to those you indicate.
I will keep on waiting

Thanks a lot, Chris.

Not an ID but some notes on similar collections as I have been working a bit on these today.

I found what seems to fit L. fimbriata and also L. alpestris sensu Racovitza on the abaxial leaf surfaces of Polytrichum commune antheridial cups. The former is particularly interesting given that it was only found on conifer leaves in the past, and the latter seems to grow on several moss and liverwort hosts. Maybe this suggests wide host preferences for some members of the group - they are often on waxy parts of host plants.

It could even be worth checking the lichenicolous ones for candidates for this collection - a previous post on this forum suggests that a species was found both on Cladonia and surrounding spruce needles. http://www.ascofrance.com/search_forum/52475

Racovitza (1959) also includes L. cetraricola as recorded on a liverwort, and Aulographella muscicola on a moss. Yours is different to both of these as well.

I still need to read more about the many lichenicolous ones...

All the best,
George
