Mollisia on very wet wood
Enrique Rubio, 09-06-2009 13:17
Enrique RubioDear friends:
This Mollisia (?) species grows on very wet wood together with Lasiosphaeriaceae species. It has cupulate and gregarious ascomata up to 0.5 mm, with amber brownish colours and small white rims.

Re:Mollisia on very wet wood
Another wiew of the little white rim.
I arrived in Zotto's keys to a M. caespiticia or M. subamberina.
What do tou think?
Many thanks again

Re:Mollisia on very wet wood
This subamberina is an interesting but problematic chose. I renamed it to cf. sublividula in the meantime. I cannot say the differences to caespiticia, actually, perhaps I confuse the two, perhaps they are one species. Fact is, however, that my colections of both taxa were on xeric bark high up on the dry branches. Possibly your branch was recently fallen in the water? Inamyloid asci in helotiales always point to xerotolerant species.

Re:Mollisia on very wet wood
Interesting thing that I did not know: xerotolerant behavior with inamyloid asci !
No Zotto. My wood was showing evident signs of having been plunged a lot of time. IIt was without bark, and very eroded.
Many thanks again

Re:Mollisia on very wet wood
I think this is difficult to say. decorticated eroded wood you can also find as dead hanging branches. Anyhow: inamyloidity of asci have to do with less efficient spore discharge (short distance only), which is of no disadvantage if the apothecia are exposed to the wind in meters above ground. It's an idea of Sherwood, and we can largely confirm it.
