At the Monfrague National Park (Spain), Etayo & Perez-Ortega (2016) found specimens on Physconia venusta with quite similar ascospore characteristics.
Germ tube test, nitrogen assimilation test, and ascospore production on malt-extract agar were also done.
2) has shown that significant ascospore release can occur when the temperature is above 45[degrees] F and the bark is wet.
According to Taylor & Hyde (1999) the germ slit is straight and running full-length of ascospore, but it was inconspicuous in the examined material.
An ascospore is a spore contained in an ascus, or which was produced inside an ascus--the spore-bearing cell produced in ascomycete fungi.
Only the ascospore ornamentation differs, and the subtle differences cannot be seen by using light microscopy.
To provide favorable conditions for ascospore liberation and infection, irrigation was for 30 s every 30 min in the morning (0600 to 0800 h) and in the afternoon (1600 to 1800 h).
Perithecia were ovoid to spherical, reddish to reddish-brown, 380-700 x 350-650[micro]m, smooth and shining, with a slightly protruding, domed and darkened apical ostiole through which ascospore were extruded in white of buff tendrils, The perithecial wall did not show a pseudoparenchymatous structure but was composed of ah intertwining network of thickened hyphae.
Observations made in experimental field plots and ascospore progeny analysis indicated prevalence of specific matings between stromata of the same host suggesting that flies are species specific in their visitation behavior.
In addition, multiple ascospore isolates were derived from single stromata (5-10 per stroma) at two sites (Albisguetli and Sihlwald).
However, species that have been placed in Neonectria and species of Nectria having a Cylindrocarpon anamorph vary greatly in the morphology of their perithecia and degrees of ascospore ornamentation.
An accurate comparison of ascospore dimensions, in 4-spored asci, a morphological character previously used to distinguish the above described truffles, was also carried out.
