Cora maxima
Cora maxima is a species of basidiolichen in the family Hygrophoraceae. Found in Bolivia, it was formally described as a new species in 2016 by Karina Wilk, Manuela Dal Forno, and Robert Lücking. The specific epithet maxima refers to its relatively large size—its thallus grows up to  across. The lichen is only known to occur in Bolivia, where it grows as an epiphyte in tropical mountainous rainforests. References
