A curious bottle-shaped fungus infecting Juniperus sp., historically known as Caliciopsis nigra.

Asci tending to dissolve early during development, saccate with a long pedicel, apparently 8-spored, releasing clumped spores.

Paraphyses absent.

Ascospores globose, moderately thick-walled, hyaline at first, turning brown with development, completely lacking ornamentation (smooth and homogeneous interior).
