Thyriothecia scattered, superficial, easily removed, rounded, blue-green to olive green, 280-400 [micro]m diam., with a central, irregular, dark ostiole. Peridium composed of an irregular meandering arrangement of hyphae, from the centre outwards, brownish green to olive green, flattened cells.
They are unique in their shape and have an opening called the "ostiole" or "eye" which is not connected to the tree but helps with the fruits' development and growth with its environment.
melanogaster, however, were opportunistic insects, probably attracted by the volatiles released by overripe fruits, and may take advantage of free access through the ostiole and damage on the epidermis.
In the front view, the stomata in the contact region between the ostiole gave a circular aspect in both environments tested with alternative media without the addition of potassium silicate (Figure 2C, D).
Pycnidia submarginal, inconspicuous, without prominent margin, rare, ostiole black; conidia sublageniform, 5-6 x ca.
After harvesting, diseases can take place through direct access by natural openings (ostiole and peduncle) or mechanical damage (injuries) arising from handling (DURIGAN, 1999).
Sexual state: Ascomata semi-immersed, scattered on putrid host stems and foliage, brown to blackish brown, subglobose or nearly globose, with a central sunken ostiole open via a circular lid, asci and pseudoparaphyses forming at the base of the peridium.
Results showed significant differences for the studied parameters (fruit size, fruit shape, flesh thickness, ostiole width, total soluble solids) in different cultivation areas.
Until this report, infestation of immature fruits was reported only in figs; but in this case as a consequence of figs' particular morphology in the ostiole region of their infructescences (Raga et al., 2003).
