Ciri dan struktur

Racoplaca melanobapha is a leaf-dwelling species that forms a very thin thallus just beneath the leaf cuticle. The thallus is usually rounded and , typically 10–20 (sometimes to 25) mm across, and made up of narrow, more or less linear (0.1–0.3 mm wide) that branch dichotomously and usually remain separate rather than forming a net. It is dark greyish green and often glossy, with a smooth to slightly wrinkled surface. The lobe margins are outlined by a fine black line (resembling a hypothallus), and the thallus commonly bears many tiny, evenly scattered black (about 0.03 mm wide), usually spaced roughly 0.1 mm apart. In section, the thallus is very thin (about 10–16 μm), with a simple . The species produces black, convex perithecia that spread slightly at the base, measuring 0.45–0.7 mm in diameter and about 150–250 μm high. The asci are narrowly club-shaped (60–110 × 6–10 μm) and contain eight ascospores that are typically 1-septate (rarely 3-septate), with pointed ends, and slightly pinched at the septum (14–22 × 3–5 μm). Pycnidia are also common; they are black and glossy, 0.2–0.3 mm in diameter, and produce , rod-shaped macroconidia (10–12 × 2–3 μm). Microconidia were not observed in the material described. The symbiotic alga was considered likely to be a Cephaleuros species, with rectangular to oblong cells 9–13 × 4–7 μm that often form continuous, radiating plates.

Habitat dan peran ekologis

In his 1952 treatment, Santesson characterised Racoplaca melanobapha as a rare species with a scattered tropical range, and suggested it was "probably pantropical". He also remarked that records from the Americas were few, which he found striking for a taxon thought to occur widely in the tropics. The material Santesson cited included a single Brazilian collection from Amazonas, together with records from Sierra Leone and from what was then the Belgian Congo (localities around Léopoldville, including Inkisi). In Asia and the western Pacific, he reported the species from Fujian in southeastern China (near Fuzhou on Gushan, 500–600 m), Sarawak (Borneo), Palawan in the Philippines, and New Guinea (including Goroka at about 1,300 m, and Valsche Pisangs Island off western New Guinea). Santesson also noted additional published Chinese reports that he treated as unverified. More recent records have extended its distribution to include Kenya, Tanzania, India (Western Ghats), Sri Lanka, Hawaii, Micronesia, and South Korea. Modern fieldwork has reconfirmed its presence in the Democratic Republic of the Congo and elaborated a more widespread presence in Brazil.

Ringkasan sumber

Racoplaca melanobapha is a species of leaf-dwelling lichen in the family Strigulaceae. The species was first described in 1874 from a specimen collected in Borneo, though its taxonomic placement remained uncertain for many decades until it was transferred to the genus Strigula in 1952 and later to Racoplaca in 2020. It forms very thin, dark greyish-green patches on leaf surfaces, with narrow branching lobes outlined by fine black lines and scattered with tiny black dots. Molecular studies suggest that what has traditionally been treated as a single widespread tropical species may actually represent several closely related species that are difficult to distinguish by appearance alone.
