Collemopsidium minutulum (Bornet) ined. (provisionally placed here, ICN Art. 36.1b)

Syn.: Arnoldia minutula Bornet, Lempholemma minutulum (Bornet) Zahlbr., Pyrenocollema minutulum (Bornet) Puym.

Lichenised. Poorly known taxon.

Substrate:

Altitudinal distribution: submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)

Note: a species with a thallus of black globules (to 0.5 mm in diam.), a Nostoc-like photobiont, immersed ascomata, 8-spored asci embedded in an amyloid hymenial gel, and ellipsoid, simple ascospores; on soil e.g. along secondary dirt roads; easy to be overlooked and distribution therefore poorly documented, with a few records from the Western Alps.
