Enchylium limosum, commonly known as lime-loving tarpaper lichen, is a species of crustose to subfoliose lichen in the family Collemataceae. This unique lichen species possesses a gelatinous thallus with a dark coloration, contributing to its distinctive appearance. It thrives in a diverse array of habitats spanning temperate to boreal-montane regions, across Europe, North America, Africa, and Asia.
The ecological preferences of E. limosum include a notable affinity for calcareous soils.[2] Such soils contain calcium carbonate or lime,[4] hence the species' common name of "lime-loving".[1] This characteristic often leads to its colonizing environments disrupted by human activity. Habitats such as quarries and spoil heaps frequently host populations of this lichen. Despite its extensive geographical distribution, E. limosum is often underestimated and overlooked, particularly in Alpine regions where its occurrence is sporadic.
The conservation status of E. limosum presents a nuanced picture that varies across different regions. In some areas, it is designated as vulnerable or critically imperiled due to threats such as habitat loss and disturbance.
E. limosum has undergone several taxonomic revisions. Originally described by Swedish botanist Erik Acharius in 1799 as Lichen limosus, it was reassigned by various taxonomists, and received its current accepted name Enchylium limosum in 2013 by Mónica Andrea García Otálora, Per Magnus Jørgensen, & Mats Wedin. Synonyms for it have included Collema forissii Szatala, Collema glaucescens Hoffm., Collema viscosum A. Massal., and others.
