Hamacanthoscypha sur Eucalyptus
Patrice TANCHAUD, 14-03-2014 15:34
Bonjour,

récolte réalisée à l'interieur d'une écorce d'Eucalyptus, asques 22 µm en moyenne, spores 5-6 x 2 µm.
J'envisagerais bien Hamacanthoscypha laricionis, si c'est possible avec cette écologie ?
Merci d'avance pour vos avis.

Re : Hamacanthoscypha sur Eucalyptus
Yes, H. laricionis does not seem to be restrictd to conifers, though mostly there. For instance, I have a find on Rhododendron leaves.

Did you test the iodine reaction? An unidentified similar taxon is inamyloid.

Re : Hamacanthoscypha sur Eucalyptus
I tested iodine reaction with Melzer and it was negative. Now, I just make a post treatment with KOH, and it is always negative.  Indeed, H. laricionis usually has a net reaction to Melzer.
