Definitions for "PYCNIDIA"
Small, flask-shaped structures that are filled with simple or branched hyphae from which bud numerous asexual spores (conidia). They may be confused with perithecia (which contain the sexual ascospores) since they both are immersed in the medulla and open through a pore in the cortex. This pore (or ostiole) appears as a brown to black dot in the upper cortex of the thallus.
An often flask shaped conidiomata of fungal tissue which is lined on the inside with conidiophores.
An asexual, globose, or flask-shaped fruiting body of a fungus that produces conidia. See Conidia.
