Description
Thallus 1-4(-6) mm high, with irregularly divided terete or compressed branches of 1-5 mm long and 0.2-1(-2) broad, verrucose when cystocarps present; hemiparasitic on Rhodymenia ardissonei; multiaxial structure, developing a cortex one to three cells thick, and a pseudoparenchymatous medulla composed of round to oblong cells measuring 20-80 microns in diameter; attachment to host contiguous and secondary pit-connected.
