Hola,
He recogido este ascomiceto sobre una rama descortezada y caida de probablemente Castaño (Castanea sativa).
Los apotecios son verdes-negruzcos, convexos de unos 250um.
Creo que se trata de algún Lecanoral, puede que alguna especie liquenizada.
¿Alguna idea ?
Muchas gracias, un saludo.
Susana

Scoliciosporum sp. Probably S. sarothamni. Note S-shaped spores.Â

Re : Lecanoral?
Wonderful docu including living and dead state as well as IKI reaction! Spiral spores are amazing, and I am curious to know in such cases whether they are righthand or lefthand curled. This can easily be seen when changing the focus of the mic to see which parts are closer to the eye and which more distant. Usually a species is either ... or.
I also experienced changes in the degree of curvature within a preparation depending on the mounting medium (H2O vs. KOH).

Re : Lecanoral?
Hola Zotto,
He intentado ver si las esporas son dextrogiras o levogiras y me resulta dificil interpretar. Te mando dos imagenes, ¿es levógira?
No he encontrado más apotecios y no he podido comprobar si la curvatura esporal cambia con el KOH.
Con respecto al IKI el himenio es hemiamiloide, porque a baja concentración de IKI, es azul y a concentración elevada rojo, excepto el aparato apical de las ascas que permanece azul.

Re : Lecanoral?
Good description of hemiamyloidity! I appreciate that you did not have too much iodine so that everything doesn't get dark and intransparent.
Your spore in side view shows a lefthanded twist I think. It seems that in the left photo the spore is with the sharp area closer to the eye than on the right photo. If you imagine a screw, this one is a lefthanded screw.
Also your right pics in top view I would interpret so, because I think the sharp end is closer to the eye than thr rest.

Re : Lecanoral?
Si, asà es, el extremo afilado más cercano al ojo, por tanto levógiro (a izquierdas).
Gracias Zotto.
