Microthyriale on Lophocolea
Enrique Rubio, 26-02-2016 15:40

Hi to everybody

Searching for helotiales on liverworts we have found these very minute (70-100 microns), superficial, scattered, ostiolate, brownish black thyriothecia (i feel they are so by the type of tissue) on decaying thallus of I pressume Lophocolea bidentata. The bitunicate asci are oligosporic, perhaps only 4-spored. Ascospores hyaline or subhyaline, 1-septate.

Have you some idea for help me?

Many thanks again

Re : Microthyriale on Lophocolea
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.

Re : Microthyriale on Lophocolea
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)?

Re : Microthyriale on Lophocolea
Hi Enrique,

I only have this - 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 - it is distinct from the true L. alpestris.

Hope this helps,

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

Re : Microthyriale on Lophocolea
The IMI Description Enrique mentions above is not about alpestris - that taxon is merely part of several new combinations into Lichenopeltella.
