Ascomata
Non-stromatic or weakly stromatic perithecia, superficial on host surface, bright reddish-orange when fresh, turning dark red or reddish-brown with age
Body
Teleomorph appearing as clusters of tiny perithecia immersed or superficial on the decaying stromata of a host fungus (not on wood directly)
Ecology
Fungicolous (mycoparasitic), growing on the dead stromata of fungi in the genus Annulohypoxylon
Microscopy
Inedible, microscopic
Fruit body
Fruit body microscopic, perithecial clusters < 1 mm in height
Dimensions
Perithecia diameter ~200-300 µm wide
Microscopy
Ascospores ellipsoid, verrucose, 8.5-9.5(–10) × 3.8-4.2 µm, 1-septate, hyaline becoming pale yellow-brown at maturity, asci unitunicate cylindrical, ~70–75 × 4–5 µm, 8-spored
