Metzgeria allionii Steph.

Notes. – Only known from the type from Gualaquiza, where it was collected by Allioni along the Río Curiapo. The species is very similar to the widespread but uncommon M. crassipilis (Lindb.) A. Evans – found by the authors along the Río Bomboiza and Río Quimi in 2019 – but differs in gemmae and younger parts of the thallus with falcate hairs (KUWAHARA, 1986; COSTA, 2008).
