Mick PeerdemanHi all,One of my earliest microscopy attempts, so
Apotecios de 1 mm, en zona dorsal de Pistacia lentiscus. Agrupaciones de esporas sin visualizar ascas, pero se intuyen, de hasta 105 x 35 micras. Ascosporas longitudinales, naviculares o en forma de boomerang, con 3 septos y multitud de pequeñas gutulas, dejando libre los extremos esporales. Ausencia de parafisis. Excípulo formado por células globosas y subglobosas.
Hi to all!
Apothecia of 1 mm, in dorsal area of leaves of Pistacia lentiscus. Groupings of spores without display asci, but will foreshadow of up to 105 x 35 microns.Longitudinals naviculars and with the form of a boomerang , with 3 septa and a multitude of small gutules, leaving the spores ends, 65-100 x 5-6 microns. Absence of parafisis. Excípulum formed by globose and subglobose cells.
Any ideas?
Thanks and greetings to all
Andy
I thought at Calonectria, but which species ?
One of them, C. paucimarosa, has been found on Pistacia but ascospores are very different.
Let's talk specialists.

Are ascomata red or darker at base? please test the changing of color in KOH, it is very impor†ant.

The specie is Calonectria pyrochroa. Send link to friend Enrique Rubio:
