Ichmadophila ericetorum 

Ichmadophila ericetorum is a lichen that loves to grow on rotting wood. I have found it once in the spring 2020 during a trip near Breightenbush Road, and again in the summer on the coastal range. I have trained myself to observe the small cup fungi and have gotten pretty good at finding some of the little black cup Ascomycetes. The apothecia (little pink discs) are the fertile surface and contain the spindle shaped spores. The matte granulated green behind the pink discs is Coccomyxa, a photobiont algae that contains chloroplasts. This means this lichen is part fungi and part algae!
