Hola, tengo esta muestra recogida en rama caida de Pinus halepensis, a unos 450 m de altitud.al verla me recordo a Sarea resinae, pero mi muestra tiene esporas que son el doble de diametro, lo cual la descarta.
lo mas parecido que veo es Byssonectria semi-immersa, que tiene esporas diferentes lo cual la descarta tambien.
En toda la documentacion que tengo ya no veo nada parecido.
La otra opcion que estoy pensando es que lo que yo creo son esporas dentro del Asca, puedan ser nucleos y no esten las esporas formadas, en este mensaje envio microfotografias de ascas en las que se ven lo que creo son esporas, a ver que les parece.
0,96 diametro.
Parafisis de dos tipos, unas finas y abundantes de X1,7--X2 y otras septadas X4--X5.
Ascas con Croziers, de 49--52 X 5--6 (inmaduras )
Esporas esfericas de 4,5--5,2, solo he podido medir 7 fuera del Asca.
Pelos en grupos densos de 43--62 X 4--4,5, formados por celulas a modo de escamas.
Un saludo
Rafael

Re : Muestra en Pino 05-02-15
Did you actually see any spores? It must be an Orbilia, and perhaps O. flagellispora. Please keep the apos for some days in a moist box at room temperature or a bit colder.

wonderful glassy processes but I do not see a trace of spores. The asci are immature.

Hola Zotto, la Orbilia que habia mirado es corpoboloides, qu es la mas parecida dentro de la documentacion que tengo, y la descarte
dejare la muestra unos dias y volvere a realizar micro.

Re : Muestra en Pino 05-02-15
O. carpoboloides is only superficially similar. Your species has nice glassy processes, unlike the septate hairs in O. carp., also the ascus apex is hemispherical and should be thick-walled in dead state.

Re : Muestra en Pino 05-02-15
Parece que despues de una semana, alguna espora se ve, solo he visto dentro de un Asca esporas, las demas estan vacias, y sueltas en la preparacion he visto muy pocas,
miden 5,6--7,2 x 3,2--3,5, con un pedunculo que llega a 15--17

Re : Muestra en Pino 05-02-15
Wonderful! So now it is a species of the difficult O. aristata group. Perhaps O. aristate, though the glassy hairs are a bit long for this. O. subaristata should have a bulbous tail base.
Is it a mediterranean site? Can you tell me the collection data?
Perhaps you could continue some days to get more spore?

Re : Muestra en Pino 05-02-15
Thanks, so this is mediterranean area. we have decided to place your sample in the mediterranean O. subaristata because of prominent teeth of glassy processes. In Spain there is actually no record of O. aristata known to us. Genetically the two are distinct, but too little is known and their morphology is very similar.

Hoi Zotto,
where does that leave my collection from Spain now?

Re : Muestra en Pino 05-02-15
we placed it in the waste basket :-)
No, it is now in O. flagellispora. The rather long spore heads are contradictory to subaristata.
It is more or less a guess in this nice group of tailed-spored Orbilias what it is, but it is also clear that not everything is only one species. The genetics help a lot, but we have the case of too much genetic difference within typical aristata collections, for which we have no explanation. Perhaps the genetics are more variable in some species than expected. For flagellispora we have only one sequence, gained only recently by Guy, so this is not enough to speak of a secured result.

Ok thanks, hopefully it will be collected and sequenced more.
