involucrellum (noun, pl. involucrellae;ascocarp term) – typically a shield-like (= dimidiate) layer of hyphae around the ostiole of a perithecium; rarely also extending below the base of a perithecioid ascocarp; developed outside the proper exciple and thus formed by thallus hyphae of the amphithecium; homologous to the thalline margin of an apothecioid ascocarp; often similar to a clypeus, but not incorporating host or phorophyte tissue; a distinct part of a single perithecium, not merging to cover several apothecia; usually distinctly pigmented and frequently carbonized, rarely including photobionts.
