Sarrameana paradoxa

Sarrameana paradoxa is a species of corticolous (bark-dwelling) lichen in the family Sarrameanaceae, and is the type species of the genus Sarrameana, a small group of corticolous lichens from cool-temperate forests of the southern hemisphere. The species forms a thin white film on bark and produces abundant black disc-like fruiting bodies with glossy margins. It is characterised by unusually long, narrow ascospores that taper at each end into hair-like tails and are often coiled inside the spore sacs. Originally described from New Caledonia, the species is now considered by some authorities to be the same as the earlier-named Sarrameana albidoplumbea from New Zealand, though this treatment remains disputed....read more on Wikipedia.
