Massarina on Ilex
Björn Wergen,

I have a collection on dead attached Ilex twigs, of which I mean it belongs to the genus Massarina. It has 0,3-0,45mm broad pseudothecia growing singly or clustered beneath the bark, inconspicuously cracking it with a small, 0,1mm long ostiolar neck. The spores are a bit "crazy": 2celled with very big guttules and constricted like I have never seen it in another species. The spores even collaps after exposuring in water after ~10 minutes and have a conspicuous, very thick sheath. Pseudoparaphyses are connected mostly above the asci, I think this is a good feature for the genus Massarina. I have checked both Bose 1961 and Aptroot 1995, but without any success. Only M. australiensis has some similar features, but way too small spores.
However, I have expected Vialaea insculpta on that twig, not another mysterious Massarina with so big spores...
BTW: I have also found some subiculum like hyphae around the pseudothecia.
Any ideas are welcome.
regards,
björn

Re : Massarina on Ilex
Hi Bjorn,
Such ascospores occur in Asteromassaria. I only know A. pulchra that has separate lenticular ascomata lacking subicular hyphae and thus is different. How big are the ascospores? I am not aware of a comprehensive study of the genus, maybe someone else on the forum can help.
Cheers,
Jacques

Re : Massarina on Ilex
Hi Jacques,
I have also looked at Asteromassaria, but I did not find something until now. The spores are given in photo 4: 40-50x14-16,5µm.
