Cher amis:Je vous prie une opinion sur cette Hamatocanthoscypha (¿) que croit sur lécorce d'un Eucalyptus vivant (á 1 m d'hauteur). Les ascomes KOH (-) jusqu'a 0.9 mm, sont sessiles (non stipitées), pourpres, brun-rougeatres dans la vieillesse.Ectal excipulum primatica to angularis, brun-rougeatre couvert de poils uncinates avec ses bases bruns et cols hyalines. Asci IKI (-), avec des crochets. Dans l'interieur des asques je vois 4-6 spores (Jamais 8?).
Merci d'avance par votre aide.
Enrique

Re:Hamatocanthoscypha sur Eucalyptus
This is an Unguiculariopsis, and we (Guy and I) have similar collections on Cornus in Luxembourg which we cannot name so far.

Re:Hamatocanthoscypha sur Eucalyptus
I made a mistake: the macro is another collection than the micro: Luxembourg, Manternach (close to place of Sarcoscypa jurana, 27.01.2008, c. 1m above ground, still attached Cornus sanguinea branch. Spores 5.2-8.5 x 2.6-3.5 µm, see attach

Re:Hamatocanthoscypha sur Eucalyptus
The otheer collection is from 13.VII.08, Tübingen-Pfrondorf, Ulmus branch in 2.5 m above ground, on wood. Spores *6-7.5 x 2.5-2.8 µm. Macro attached. Same species or not? The genus is very crazy!
Let me also know your collection data. We noted that in these finds the young asci are 8-spored but 2-4 spores abort during maturation.

Re:Hamatocanthoscypha sur Eucalyptus
La Candaliega (Asturias) Spain, 28-II-2009, Eucalyptus globulus bark (1 m), ERD-4702. I think , only four fully mature ascospores exist in mature asci. Many times I have seen some spores aborted in 5-6spored asci..
I send you by e-mail my images of this collection.
Thank you, Zotto
