Recintemente encontre este hongo creciendo sobre R. rufulum, algunos apotecios crecen directamente sobre los Histeriotecios. Ascosporos globosos, hialinos, 3 - 5 micras, uniseriados, no reaccion amiloide. Tal vez alguien podria ayudar en la identificacion.

Prehaps
Unguiculariopsis ravenelii = Pithyella hamata Growing on Eutryblidiella hysterina = Rhytidhysteron hysterinum

Re : Discomiceto sobre Rhytidhysteron
Yes it is, probably.
But...
After reading Zhuang in Mycotaxon 32, we see that there is U. ravenelii subsp. ravenelii on R. rufulum (in America) and U. ravenelii subsp. hamata on R. hysterinum (in France and Asia).
But there is Unguiculariopsis hysterigena on R. rufulum (in Asia) . A complete description of your fungus would be useful even if we can believe that it is ravenelii.
