Apothecia orange, cup-shaped, 2 to 9 cm in diameter, without a differentiated stipe (sessile) and with very fragile, brittle flesh.

Asci cylindrical, 8-spored, uniseriate, 185 to 200 µm long, 10 to 13 µm wide, with basal croziers difficult to observe, and inamyloid in Melzer's reagent.

Paraphyses 3 to 4 µm wide, enlarged at the apex up to 6 µm, septate, with orange granular content inside that turns greenish when iodine compounds are applied, protruding very little or not at all above the level of the asci.

Ascospores elliptic, hyaline, distinctly ornamented with a prominent reticulate network, with spinose appendages at both ends, 14 to 16 µm long, 10 to 13 µm wide (excluding ornamentation), containing two oil droplets inside.
