Parmotrema zicoi is a species of saxicolous lichen in the family Parmeliaceae.

It was originally described from collections made in Serra do Caraça, Brazil, where it was found growing at an elevation of 1,330 m (4,360 ft).

The specific epithet zicoi honours the priest Tobias Zico, who, as a former administrator for the Parque Natural do Caraça, promoted the "preservation of a most important type locality for numerous lichens, animals, and plants in Brazil".

[1] Occasionally, the medullary K spot test reaction is positive, producing a very light yellow colour that indicates the presence of traces of atranorin in the upper part of the medulla near the cortex.

P. zicoi has short bacilliform-shaped conidia that are less than 5 μm long.
