perithecium การใช้

• The mature perithecium has a flask-shaped structure.
• The perithecium contain asci while the pycnidium releases conidia.
• When each ascus becomes engorged with fluid it extends outside the perithecium and releases spores.
• A mature perithecium may contain as many as 300 asci, each derived from identical fusion diploid nuclei.
• The asci are protected by a perithecium, a flask-shaped ascocarp, in which the pathogen overwinters.
• Its ascospores ( within asci ) are found in the ascocarp " Cochiobolus ", a type of perithecium rare in nature.
• As the above events are occurring, the mycelial sheath that had enveloped the ascogonium develops as the wall of the perithecium becomes impregnated with melanin, and blackens.

• In their 1989 review, Rogerson and Samuels did not accept this genus as valid, stating " variations in these features occur, occasionally in a single perithecium ", and they reclassified the fungus in " Hypomyces ".
• The three most common spore body types being raised discs called "'apothecia "'( singular : apothecium ), bottle-like cups with a small hole at the top called "'perithecia "'( singular : perithecium ), and "'pycnidia "'( singular : pycnidium ), shaped like perithecia but without asci ( an ascus is the structure that contains and releases the sexual spores in fungi of the Ascomycota ).
