Exempel på hur man kan använda PERITHECIUM i en mening

• Being that it is a polycyclic disease, it can asexually produce conidia in a pycnidium which continually inoculates new hosts throughout the growing season, as well as sexually produce ascospores in a perithecium which acts as an overwintering structure.
• However, no correlation has been established between precipitation intensity and ascospore density, indicating that ascospores are not actively dispersed by rain splashes; rather, they are forcibly ejected into air currents, granted by the long beak and narrow restricted ostiole of the perithecium and the expulsion of spores from high  internal pressure caused by a swollen, wetted perithecium.
• The asci are protected by a perithecium, a flask-shaped ascocarp, in which the pathogen overwinters.
• The ascomata are in the form of a perithecium, and these structures are often —meaning they have a shield-like stromatic growth, made of both fungal hyphae and host tissue, around the ostiole (opening).
• The ascospores and the mucilaginous matrix form a paste that is extruded through the apical opening in the perithecium producing "cirrhi" resembling toothpaste squeezed out from a toothpaste tube.
• In Hydropunctaria, the involucrellum is black, often with a rough or uneven upper surface, and it can be of several forms: apical (where the involucrellum occurs only around the ostiole, but extends some distance laterally) to dimidiate (where the involucrellum covers only the upper portion of the perithecium) or entire (where the involucrellum completely surrounds the perithecium).
• It has medium-sized hemispherically protruding perithecia, more or less spherical pale exciples with a well-developed involucrellum of medium thickness that usually reaches down to the middle part of the perithecium (rarely deeper).
