Century Dictionary and Cyclopedia
    • n conceptacle That in which anything is contained; a vessel; a receiver or receptacle.
    • n conceptacle In botany: Originally, as used by Linnæus, a follicle—that is, a fruit formed of a single carpel dehiscing by the ventral suture.
    • n conceptacle In lower cryptogams, an organ or a cavity which incloses reproductive bodies, usually spores, with or without special spore-cases: applied without reference to the origin of the spores, whether sexual or asexual. In Sphœrioideœ (of Fungi imperfecti) the conidial spores are borne on short threads within conceptacles; in pyrenomycetous fungi the conceptacle (perithecium) contains spores in asci (thecæ); in Florideœ (red algæ) either cystocarpic spores or tetraspores may be contained in conceptacles; in Fucaceœ (rock-weeds, etc.) antheridia containing antherozoides, and oögonia containing o⊙spores, are formed in conceptacles. The sporangium, as of ferns, was formerly included under this term, but it is now rarely used in that sense. Also conceptaculum.
