Notes:
Parasitic lichenicolous fungi occurring on Aspicilia cyanescens (observation 242882).

Thallus appears as black strands on apothecia and thallus, sometimes in a radiating pattern. At 1000x in K, the cells are round and brown. Did not get a look at the ascomata, but apparently crushed one in the mount and found asci and spores.

Asci globose, spores 1-septate, slightly brown, appearing halonate and hyaline when young
