iny, flask-shaped fruitbody (ascoma) produced by some sac fungi, usually less than 1 mm in size. View an illustration of the perithecium.
flask-shaped or subglobose, thin-walled ascocarp (fungal fruiting body), containing asci and ascospores and having an ostiole (pore) at the apex, through which spores are expelled or otherwise released.
A round to flask-shaped, thick-walled spore case containing asci and with an ostiole (pore).
the sub-globose or flask-shaped ascocarp of an Ascomycete fungus.
(Pl. perithecia) a pear shaped, ostiolate fruit body characteristic of Ascomycetes.
(pl. perithecia) - A closed bulb- or ball-shaped fruiting body with a pore through which ascospores are extruded, usually in a gelatinous paste.
Flask-shaped fruiting body of some Ascomycotina, from the neck of which asci are discharged
(pl. perithecia): The globular or flask-shaped ascocarp of the Pyrenomycetes, having an opening or pore (ostiole) (1) perithecium
A closed ascocarp with a pore at the top, a true ostiole, and a wall of its own. (Pl. perithecia.) ( 23)
A fruiting body having asci in a basal group or as a layer; perithecia are usually flask shaped, with an opening through which the asci or ascospore escape.
the flask-shaped fruiting bodies of certain Ascomycetes. They contain asci
a closed ascocarp with a true wall and an ostiolate opening.
