Ramalina calicaris

Ciri dan struktur

Ramalina calicaris is a fruticose (shrubby) lichen with a greenish grey thallus, anchored to the substrate by a basal holdfast. Thalli are often tufted when young, but may become longer and more pendent with age, reaching about 15–20 cm in length in some accounts. The branches (laciniae) are typically strap-shaped and relatively sparingly branched. They are often distinctly channelled (canaliculate) and commonly about 2–3 mm wide, though broader forms have been reported. The surface is described as smooth to weakly wrinkled, and thalli may appear stiff and spiky when dry. Small pores (pseudocyphellae) penetrate the surface; these range from dot-like to spindle-shaped and may be few or numerous depending on the specimen. Apothecia (spore-producing structures) are usually frequent and in form, typically positioned at or near the tips of the branches, though they can also occur along the margins. They may develop on bends of angled branches and can sometimes show a short spur-like projection. The disc has been described as pale pink-ochre with a thin . The spore-bearing structures (asci) each contain eight spores and have an apical tip whose iodine-staining pattern matches the Bacidia type. Ascospores are hyaline and 1-septate, with reported sizes around 10–16 × 5–7 μm. The photosynthetic partner () is a green alga. Spot tests on the medulla have been reported as negative (K−, C−, KC−, P−, UV−), with some regional treatments summarizing this as K−/C−. Chemically, the cortex contains usnic acid, while the medulla is variably reported as lacking additional substances or containing compounds of the sekikaic acid complex (including sekikaic and homosekikaic acids).

Habitat dan peran ekologis

Ramalina calicaris is primarily corticolous (bark-dwelling), typically growing on branches and twigs rather than on trunks. It is most often associated with trees and shrubs with relatively nutrient-rich bark, and is reported as occurring frequently in coastal settings in parts of its European range. Aptroot and de Bruyn (2011) described it as occurring mostly in coastal regions in Europe but emphasized that, unlike several other Ramalina species, it is not a maritime lichen; they also suggested that its frequent occurrence on small twigs, possibly in the canopy, may contribute to under-recording. In Italy it is recorded mainly from deciduous trees (more rarely conifers), with occurrences reported especially on branches in humid beech forests, though some older records have been flagged as needing confirmation. In Britain and Ireland, the species is mapped and assessed as Least Concern within that framework, and it is described as most frequent in western districts, with more easterly records considered local. Italian records span multiple regions, but distribution reporting has been complicated by historical misidentifications, with at least one earlier regional report explicitly attributed to confusion with other taxa.
