Tubeufial?

Hola,
Pseudotecios muy pequeños, unos 120um de diámetro, errumpentes en la corteza de Prunus spinosa.
Realmente no sé siquiera a que orden pertenece. He pensado que podría pertenecer a tubeufiales, pero con dudas.
¿Qué opinais?
Un saludo
Susana

Re : Tubeufial?
Hola Susana,
Perhaps compare it to Leptorhaphis laricis?
A key to the genus is available here:

Re : Tubeufial?
Hola Nick, muchas gracias.
Efectivamente las características encajan con el género Leptorhaphis. Sin embargo, no sé si encajaría con L.laricis por que leyendo el artículo dice: "Hymenial gelatin bluish in iodine" y yo cuando le apliqué IKI no observé ninguna coloración azul, el himenio se coloreaba amarillo-naranja-pardo. Tal vez pudiera encajar en L. epidermidis o L. contorta. Tendría que intentar conseguir hacer un corte de un pseudotecio, pero no he conseguido encontrar ningún ascoma más en la rama de Prunus.
Seguiré buscando.
Saludos
Susana

Re : Tubeufial?
Hola Susana,
Difficult because I noticed that Begoña used KOH pretreatment in her studies (Page 88), perhaps the hymenial tissue is hemiamyloid - This could explain why no blue was visible in your specimen....
If you find any more ascomata it would be interesting to see the material pretreated with KOH.

Nick

Re : Tubeufial?
Cierto, he mirado como me dices el método de análisis de las preparaciones y previamente hay un tratamiento con KOH.
Sigo buscando la especie, pero sin exito.
Muchas gracias Nick,
Susana
