Description Dennis:
Ascocoryne sarcoides (Jacquin ex S.F. Gray) Groves & Wilson, op. cit.: 40(1967).
Apothecia superficial, clustered, cupshaped, sessile or short stalked, disc concave or flattened, often irregular and lobed, up to 10mm across, reddish-purple, exterior usually minutely scurfy, concolorous. Asci cylindric-clavate, up to 160 x 10 µm, 8 spored; ascospores often biseriate, elliptical to inequilateral, 10 - 19 x 3-5 ym, at first non-septate with 2 oil drops, becoming usually 1-septate, occasionally 3-septate, sometimes germinating within the ascus, paraphyses slender, often abruptly swollen to 4 ym thick at the tip. Apothecia are almost invariable accompanied by a similarly colored conidial state which has been called Coryne dubia Person ex S.F. Gray and Pirobasidium sarcoides von Höhnel. The name Coryne applies to the conidial state, hence a separate generic name had to be coined for the apothecia. On stumps and fallen logs of all kinds, esp. Fagus. August to December. Very common.
Ascocoryne cylichnium (Tulasne) Korf in Phytologia 21: 202 (1971) is very similar but often has larger apothecia and is distinguished by its long ascospores 18-30 x 4-6 ym, which become multiseptate and bud off spherical secondary spores while still in the ascus.
Ascocoryne solitaria (Rahm) Dennis in Kew Bulletin 25: 343 (1971) has turbinate apothecia up to 1cm. diameter with light brown disc, drying black and ascospores 9-15 x 3,5-4 ym, usually 1-spetate, on dead wood.
