Sarcoscyphaceae

~ Pezizaceae.

Anamorphic forms occurring (these hyphomycetous).

Morphology. The fruit-bodies producing asci and ascospores; discoid, or cupulate, or cushion-shaped (leathery or somewhat gelatinous, the hypal cells of the excipulum often embedded in a gelatinous matrix, the interascal tissue composed of paraphyses); stipitate to sessile; small to medium sized; in Sarcoscypha coccinea, about 2–6 cm across; gelatinous and somewhat translucent when moist, or not noticeably gelatinous when moist; usually brightly pigmented (within the disc, the paraphyses usually pigmented at their swollen apices); internally orange to yellow, or red (externally dark); apothecial; brightly pigmented with carotenoids (in the paraphyses); stromata absent. The asci cylindrical, persistent. The walls of the asci not staining blue with iodine. The ascospores elongate; smooth, or ornamented; hyaline; simple; multinucleate.

The hyphae without clamp connections. The hyphal walls lamellate, double layered, with both layers electron dense.

Ecology. Saprophytic. The fruit-bodies borne on the ground (then often in rich soil), or on dead wood (S. coccinea common on decayed branches).

British representation. 5 species in Britain; Microstoma, Pithya, Sarcoscypha.

World representation. 21 species; genera 10. Cosmopolitan.

Classification. Ascomycota; Ascomycetes; Pezizomycetidae; Pezizales.
