Named in honour of Dr. Neli Kika Honda, a researcher of lichen chemistry, Hondaria leptospora is notable for its long, thin, transversely-septate ascospores, the longest within its family.

Notable features of the lichen include its ascospores, which are long and thin (typically 120–175 by 2–4 μm) and transversely septate, a characteristic that helps distinguish it from other similar species.

[4] In terms of appearance and morphology, Hondaria leptospora shares notable similarities with other species, such as Arctomia papuanorum and A. uviforme.

[4] Hondaria leptospora distinguishes itself by having the longest and thinnest ascospores within the previously identified C. fasciculare group, according to prior research by Degelius (1974)[5] and Otálora and Wedin (2013).

The region is noted for its diverse vegetation formations, including the Pantanal wetlands, the Brazilian savanna known as the Cerrado, and the Chaco.
