Sarcoscypha
Malcolm Greaves, 15-03-2017 17:44
Malcolm  GreavesIs it unusual for the spores of Sarcoscypha austriaca to germinate while still in the ascus? One particular find had lots of spores germinating both outside and inside the ascii.

Re : Sarcoscypha
Germinable spores of all ascomycetes may germinate inside the asci, but only when the asci are dead. Why shouldn't a spore germinate in an ascus when the humidity allows? 

But inside living asci only a few fungi do, by forming ascoconidia. Sarcoscypha does not belong to these.

Living asci are distinctly larger than dead asci, you can easily  make the test with KOH or MLZ, shrinkage is enormous.

Re : Sarcoscypha
A classic example of forming ascoconidia can be found in Claussenomyces atrovirens.

Re : Sarcoscypha
Thanks Chris, you are right for the spores and conidia but the asci are all dead on these pics.

Attached a living and dead ascus of C. atrovirens. The conidia are held together in 8 balls which also contain the remnants of the collapsed ascospores (invisible).

Re : Sarcoscypha
Thanks Zotto
I hadn't realised the asci were dead - the photo's were taken in 2013, so I was working backwards when I said that. What are the clues that these are dead? I have edited my former post accordingly.

Re : Sarcoscypha
It is a classical example: apical thickening swollen, conidia distributed ácross the entire lumen. Compare my two pics. If you add KOH to the living ascus it will suddenly look light the dead one I posted. f you don't believe, I have a video :-)
