Lichenodiplis opegraphae  

Anamorph: conidiomata immersed in the thallus or lirellae of the host, 40-60 µm diam., to ca 100µm tall when in lirellae, scattered, sometimes becoming confluent in heavy infections, brown, at first globose but becoming very irregular in shape, ostiole forming by an irregular breakdown of the upper wall of the conidioma, becoming gaping and sometimes almost cupuliform with age; wall poorly delimited, composed of 2-3 layers of intertwined short-celled hyphae forming a layer only 3-5 µm thick, hyphae olivaceous, sometimes becoming almost cellular just below the conidiogenous cells, subhyaline to pale olivaceous brown, 1.5-2.5 µm diam. Conidiogenous cells 4-7 (-9) x 1.5-2.5 µm, subcylindrical, distinctly annellate with up to 6 annellations, olivaceous brown, smooth-walled. Conidia 3.5-5 x 1.5-2 µm, ellipsoidal to cuneiform, narrowed to an abruptly truncated base, basal frill sometimes visible, olivaceous brown, aseptate, not conspicuously guttulate, smooth-walled.
Teleomorph: not known.
