I was please to find Pityrogramma pearcei a few times while working on P. N. Las Orquideas in Antioquia, Colombia.  Similar to other Pityrogramma, it inhabits disturbed sites; I found it growing along trails. It also have an epidermal farina like many Pityrogramma. In this case, it covers the lower portion of the petiole and is absent from the lamina of the mature leaf. Unlike many of the other species in the genus, it is not frequently collected. It is known primarily from the northern Andes, extending northwards to Costa Rica and southwards to Peru.
