Description: Fruit bodies ostiolate, 125–450 × 8–10 µm, wall 7–10 µm thick, outer layer composed of interwoven, 2–4 µm wide, septate hyphae. Fruit-bodies immersed in long, cylindrical, hyaline pieces of a host plant that usually measure 70–125 µm in diameter, but where the tissue is infected by the fungus and fruit-bodies are present, this tissue has a diameter of 220–500 µm. The cylindrical cells of the host tissue measure 10–20 × 35–70 µm. Through the host tissue and the fruit-body walls the ascospores can be observed, and most ofthe fossil fruit-bodies still contains ascospores. Ascospores one-septate (35–)37–43(–48) × (10–)11–14(–17) µm, at both ends with 0.8 µm wide pores.
