Hola,
Encontré este apotecios creciendo con abundancia sobre una rama caida, descortezada de planifolio, probablemente de castaño. El tamaño hasta 250um de diámetro.
He pensado que puede tratarse de Laetinaevia uvidula, pero con dudas y me gustaría saber si crees que es o no.
Gracias, un saludo
Susana

Re : Naevioideae
Hi Susana
I also thought about uvidula. The apos remind me more of Xylogramma (Durelly atrocyanea), but not the micros.
No idea. L. uvidula has a pronounced apical thickening and thin lateral walls. This one tends to thick lateral walls and less thick apical wall. Also spore shape is more cylindrical here.
I could imagine that the two species are similar in their DNA, though. It seems there exists a group of lignicolous species that sharply differ genetically from herbicolous ones.

Re : Naevioideae
MuCHAS gracias Zotto por tus comentarios.
Ciertamente, he mirado Durella atrocyanea y macroscopicamente serían indistinguibles, pero la micro es muy distinta.
Un saludo
Susana

Re : Naevioideae
Just curious, but is that algae near all those apothecia?

Re : Naevioideae
Surely, but this is normal with drought-tolerant discos, Orbilias often grow like this but a connection was never shown to be probable.

Re : Naevioideae
Got it. Thank you. I am thinking about this subject.

Re : Naevioideae
Si había un alga creciendo por toda la rama.
Desconozco su nombre.
