In leaves of Phillyrea
Javier Ormad, 10-12-2012 18:00
Javier Ormad¡Hola a todos!
Os presento este especimen:
 Peritecios de 0.3-0.5 mm, distribuidos por parte o toda la superficie dorsal de la hoja.
Ascas ventrudas, octosporadas, biseriadas, no amiloides de 70-90 x 18-20 micras. Esporas nectriformes con un septo marcado, que constriñe la espora, generalmente inferior a la zona central, con 1-2 septos más en la zona superior y 0-1 en la inferior, con múltiples gutulillas en las zonas interseptales, de 18-21 x 5-6.5 micras. Parafisis filiformes, septadas, ramificadas, algunas rectas y otras curvadas.
En hojas secas y deterioradas de Phillyrea angustifolia. Tal vez Leptosphaeria..........?
Agradecería ideas.
Saludos cordiales.


Perithecia of 0.3-0.5 mm, distributed by part or entire dorsal surface of the leaf. Ventrude asci, 8 spores, biseries, not amyloid from 70-90 x 18-20 microns. Spores nectriformes with a marked septum, which constrains the spore, generally less than the central area, with 1-2 septa more in the zone above and 0-1 in the bottom, with multiple in interseptal gutules areas, from 18-21 x 5-6.5 microns. Filiforms paraphisis, septate, branching, some straight and other curved.
In dry and damaged leaves of Phillyrea angustifolia. Leptosphaeria perhaps...?
I would appreciate ideas.
Best regards.
Javier
