The etymology of the word Pityrogramma calomelanos is as follows:
1. Pityrogramma: This is derived from the Greek word pityron meaning husk, scale, or bran and the Greek word gramma meaning letter or character. The name likely refers to the scales or indusia that cover the sporangia (spore-producing structures) of this fern genus.
2. Calomelanos: This is derived from the Greek word kalos meaning beautiful and the Greek word melas meaning black. The name refers to the black color of the rhizome (underground stem) of the fern.
