Ecology, geology: On soil, Plandogau soil, WRB World Soil Reference Haplic Gypsisol (Siltic); Soil Taxonomy: Gypsic Haploxerepts, Association of gypsum Haploxerepts. The soils of the Plandogau cartographic unit are very deep, well drained, of medium textures with few coarse elements. They were formed on terrigenous detrital materials rich in gypsum. They present many vermiform secondary accumulations and gypsum crystals, which give rise to a gypsum horizon.

Etymology of names:
Diploschistes (Norman, Conat. Praem. Gen. Lich.: 20, 1852) from the Greek δίπλοσ-σχίζω, meaning "doubly divided”) we interpret that the author means that the spores have transverse and longitudinal septa, since it is detailed in the description of the species (see attached description). The epithet muscorum, is the genitive plural of the Latin “mūscus”, meaning moss.

The epithet diacapsis, from the Greek διακαψής. We have not found the explanation for this designation in the bibliography, δια means "through" and κάψής could be derived from κάμψα meaning "box".

Mariano Lagasca (1776–1839), was a Spanish botanist, writer and doctor. He was the director of the Royal Botanical Garden of Madrid. Lagasca sent Erik Acharius samples of lichens that he considered of interest, as is the case of a sample of Diploschistes diacapsis that has been designated as the lectotype of the species.
