This lignicolous species was recently described from the Netherlands and is apparently indistinguishable in the field from Absconditella lignicola (Suija & van den Boom 2023). It differs in cell structure of the excipulum (hyphae parallel in A. lignicola), smaller apothecia (0.05–0.15 mm vs. 0.1–0.2 mm) and ascospores (9–12 × 4–5 μm vs. 10–15 × 4.5–6.5 μm). However, according to our observations, these characters are difficult to use because the excipulum structure is not easily visible and the ascospore size is more variable than reported by the above authors. However, the size of the fruiting bodies could be a clue to distinguish the two taxa.
According to the data from environmental samples, A. sublignicola is significantly more abundant in Czech forests than A. lignicola (Vondrák et al. 2024). It is therefore very likely that a substantial part of the Czech records of A. lignicola is related to this name and it is a common pioneer lichen.
