Gastrotheca phelloderma can be distinguished from other species of Gastrotheca by the two dark brown paravertebral dorsal markings, showing pronounced longitudinal ridges and warts. Two other species of Gastrotheca, G. ossilaginis and G. phalarosa have range overlaps with G. phelloderma. Gastrotheca ossilaginis can be differentiated from G. phelloderma the presence of integumentary-cranial co-ossification, small round granulations on the skin of the dorsum and direct developing reproduction in G. ossilaginis. Gastrotheca phelloderma closely resembles, G. phalarosa but can be differentiated by the black ventrum with white spots and prominent dorsal pustules on G. phalarosa (Lehr and Catenazzi 2011).
Coloration in life is highly variable, but has only been described from photographs of two specimens. The male specimen has a cream venter with brown spots and paravertebral brown rows. The ventral surface of the hands, feet and pericloacal region is yellow. The female specimen has a greyish-tan dorsal surface with a reddish-brown perivertebral stripe on a pale grey background. The flanks are greyish-tan with some tiny dark brown spots. A small number of pale green flecks are found dorsally on the head and laterally below the eye. The dorsal surface of the extremities has reddish-brown patched surrounded by dark brown that is further surrounded by pale grey. The iris is reddish-brown with minute black reticulations and the pupil is ringed with bronze. In preservative, the dorsal and lateral ground color is dark grey with various greyish-brown markings. The flanks are dark grey with tiny black spots, the throat ranges from pale grey to white with some black spots on the edges. The chest, belly and extremities are cream ventrally, with the exception of the pale grey tarsus (Lehr and Catenazzi 2011).
