Another strange Mollisia on Sarothamnus scoparius (Cytisus s.)
Enrique Rubio, 30-07-2012 19:50
Enrique RubioHi to all
These blackish, sessile and minute ascomata grew on the wood of lying branches of Sarothamnus scoparius at 1500 m of altitude.

The asci are IKI negative (KOH pret. = negative too), croziers + and they have 8 ascospores 3-septate inside the living asci.

Ascomata KOH negative. Marginal 'hairs' blackish brown 2-3 celled  Medullary excipulum is subhyaline. Ectal excipulum blackish brown or olivaceous black.   


The provisional Baral's name of 'Mollisia cytisi' has asci IKI bb
I don't know this species. Can you help me again?
Many thanks

Enrique

Hi Enrique

what strange fungus! The spores look as like Durella (Xylogramma), but excipulum and paraphyses with VBs speak for a Mollisia! How large are the apos?

Hi Zotto
The apos are minute, up to 1 mm in diam. 
In fact, when I saw the spores I thought in a Durella species but thes Vb's of the paraphyses and the excipulum speak clearly for a Mollisia species.

VBs actually exist in some Durella species (D. connivens, D. commutata), but the excipulum is very different.

Very interesting! A Mollisia with 3 septated spores?

Well, that exists, especially on grasses. On wood I know only some with 1-septate spores I think.

Yes I know the ones on grasses but not on wood...they always have non-septated spores in my area :D
