We found that these locations had the greatest probability of high levels of overwintering inoculum and serve as "canaries" for when ascospore
release does occur.
were reddish purple, lenticular, 5-6 x 3-4 [micro]m, and smooth.
were extruded in creamy white colored masses deposited around the ostiole.
It forms fruiting structures (stromata) producing conidia (asexual spores) and ascospores
(sexual spores) around developing grass inflorescences, thereby preventing host flowering and seed set.
Discriminating factors seem to be, at contrary, the ascospore
volume in tetrasporic asci and, overall, the enzyme electrophoretic pattern (Pacioni and Fantini, 1997; Pacioni and Pomponi, 1991).
The infections from germinating ascospores
occur as discolored chlorotic spots on the surface of basal leaves on the vine.
On the basis of a study of coprophilous fungi from Zulia state, Venezuela, one specie of the family Coniochaetaceae, with cleistothecial ascocarp and ascospores
with germ pore was isolated from dove dung.
hypoxylon commonly produces viable conidia and ascospores
in natural populations, the frequency of infection of new host plants by spores appears to be low (Diehl 1950; Clay 1994).
57 mm, lips more or less open exposing a narrow red disc; pseudoparaphyses hyaline, abundant, filiform, branched, longer than asci; epithecium ferrugineous to red-brown, 3 % KOH staining purple; asci cylindrical-claviform, (4-)8-spored, 110-180 x 14-20 [micro]m; ascospores
reddish brown, uniseriate to biseriate, muriform, appearance not parenchymatic, with 4-6 transverse and 1 longitudinal septa, ellipsoid, constricted at the median septum, 16-26(-28) x 8-10 [micro]m.
have rough wall, reddish brown in color with a diameter of 4.
Therefore, the aim of this study was to evaluate the effects of fungicides and a biological product based on Trichoderma harzianum on the inhibition of the carpogenic and ascospore
germination of S.
Terminal hairs with 4-7 close spirals accompanied with a few long, flexuous hairs, forming a relatively compact head, Ascospore
