[1] Found in Taiwan, it was scientifically described by Hiroyuki Kashiwadani, Kwang Hee Moon, and Ming-Jou Lai in 2006.

Unlike some related species, R. inclinata lacks soralia (reproductive structures) and pseudocyphellae (small pores on the surface of the thallus).

Apothecia (cup-like structures containing spore-bearing tissue) are rare and lateral, with a more or less convex disc lacking a white margin.

Additionally, the chondroid tissue of R. inclinata is smooth, while that of R. litoralis is distinctly cracked, and does not spread into the hyphae of the medulla.

[2] Ramalina inclinata is known only from several locations near the type locality in Taiwan, specifically on steep conglomerate rocks near the top of Mount Dajian in Pingtung County.
