Which fungal fruiting body is cup-shaped?

Among ascomata diversity, apothecium represents open cup, saucer or disc-shaped fruiting body characteristic of discomycete Ascomycota including Peziza, Ascobolus and Peziza allies as well as lichenized groups. Hymenium consisting of palisade of unitunicate or operculate asci interspersed with sterile paraphyses lines concave upper surface exposing asci at maturity, enabling active forcible ascospore ejection into air currents. Margins may be hairy ciliate. Distinguishes from cleistothecium completely closed lacking ostiole, perithecium flask-shaped with narrow ostiole at apex and basidiocarp mushroom producing basidia not asci.

Cleistothecium, perithecium and apothecium are types of

Ascocarps are fruiting bodies of Ascomycota protecting asci and ascospores during maturation and facilitating dispersal. Morphological types include cleistothecium closed spherical without ostiole requiring decay, perithecium flask-shaped with apical pore for shot discharge, apothecium open cup-shaped exposing hymenium to environment. These structures differentiate ascomycete taxonomy and ecology adapting to habitats. Basidiocarps belong to Basidiomycota bearing basidia, sporangia produce sporangiospores in zygomycetes, conidiophores are asexual hyphae. Thus cleistothecium, perithecium and apothecium collectively denote diverse ascocarp architectures regulating spore liberation. Clamp connections and croziers maintain dikaryotic state during vegetative extension ensuring balanced nuclear ratio and genetic complementation for fruiting.
