Ciri dan struktur

Leucodermia leucomelos has a foliose to somewhat fruticose thallus that grows loosely attached or partly free from its substrate in a characteristic leucomelos-growth form, forming loose circular patterns (rosettes) or tangled mats 5 – 15 cm wide. The thallus consists of elongated, narrow 0.5 – 4 mm wide that branch and bear long, typically branched, dark marginal . The upper surface is whitish to cream-coloured, smooth and somewhat shiny; the lower surface is usually white, sometimes pale to pinkish brown and rarely purple, and lacks a cortex except at the margins as well as rhizines, appearing (cobwebby) to woolly or powdery. Soredia are variably developed, typically arising on the distal portion of the lower surface which becomes exposed as the lobes curl upwards. The species rarely produces apothecia; when present they are (with a ), subterminal and somewhat stalked, and measure about 2 – 5 mm across with margins ranging from to and with small triangular lobules up to 3 mm long. The is dark brown to black and may be pruinose. The asci are club-shaped () and eight-spored with a Lecanora-type structure and characteristic iodine reactions; the are brown, ellipsoid and 1-septate, measuring 30–50 x 15–23 μm, and show Polyblastidium-type development with sporoblastidia. Pycnidia are rare and immersed, producing hyaline bacilliform conidia measuring 4–5 x 1 μm. The photobiont is a green alga.

Habitat dan peran ekologis

The North American range of Leucodermia leucomelos extends from Belleville, Ontario in the north, south to Mexico. The lichen grows in select locations spanning the central/southern Appalachian Mountains down to Florida and stretches along the North American west coast from Vancouver Island through Mexico and into Central America. Despite its broad distribution, it is not regarded as a particularly common lichen in North America. In Ontario, Canada, it was recorded for the first time in over 150 years in 2019. In the Azores, where it is abundant, it grows on sunny coastal rocks and walls to mossy trees in the moist cloud forest to elevations of 1000 m. In Afromontane forests of South Africa, L. leucomelos occurs at altitudes between 1500 and 1600 metres, where it experiences a climate characterized by warm, wet summers and dry, cold winters with temperatures reaching freezing. In these habitats, the species shows particular affinity for Leucosidea sericea, though it can colonise various other tree species. In the Pacific Northwest of North America, Leucodermia leucomelos is a rare coastal lichen. It grows in forested dunes, marine terraces, and headlands up to elevations of 250 m. It is located within 4 km of the coast, specifically in the marine fog belt stretching from Point Reyes near San Francisco to the boundary of Oregon and Washington.

Ringkasan sumber

Leucodermia leucomelos is a species of fruticose lichen in the family Physciaceae, and the type species of the genus Leucodermia. This species is widely distributed in tropical, subtropical, and warm temperate regions, where it grows on both trees and rock faces. The species forms pale, narrow branches 4 – 8 cm long that divide repeatedly as they grow. The cream-coloured to whitish branches have distinctive long, dark hairs () along their edges, and typically grow in loose clusters on trees or rocks.
