Leptogium chloromelum

Ciri dan struktur

The species is characterized by its distinctive ridged thallus structure and reproductive bodies positioned near the margins, features that align it with a group of related Leptogium species. Leptogium chloromelum forms patches 2–7 cm across with a lead gray to greenish upper surface and paler underside. The body of the lichen consists of numerous radiating that branch and reconnect with each other. These lobes are elongated and 1–4 mm wide, with thickened margins and tips that remain unbroken. The surface has a distinctly wrinkled appearance, with the most prominent wrinkles running lengthwise along the lobes rather than across them. The lobes are quite thick (125–500 μm) and have a simple internal structure consisting of a single layer of irregularly rounded cells about 4–9 μm in diameter. A second cortical layer develops only beneath the reproductive structures. The fungal threads (hyphae) are 2–4 μm in diameter and loosely interwoven, while the algal partner forms spherical cells 3–5 μm across arranged in long chains throughout the lichen body (thallus), though they are most abundant near the upper and lower surfaces. The spore-producing structures (apothecia) are common and sit directly on the thickened lobe margins without stalks. These -shaped structures are 0.5–2.5 mm wide with concave to nearly flat, red-brown surfaces. The rim around each disc matches the wrinkled texture of the main thallus. The spore-containing sacs (asci) are club-shaped to cylindrical and measure 80–120 × 12–23 μm. Each sac contains eight colorless ascospores that are elliptical with pointed ends, measuring 20–30 × 9–12 μm, and divided by 3–5 cross-walls and 0–1 lengthwise divisions.

Habitat dan peran ekologis

Leptogium chloromelum is found throughout the American tropics, with its range extending across the southeastern United States and reaching north to New England, and west to Arkansas and Texas. This bark-dwelling lichen grows on various tree species including several types of hardwoods and oak, and has occasionally been found growing on cedar and, in rare instances, on rock surfaces. The species is relatively common in parts of Brazil, particularly in the state of Mato Grosso do Sul, where it has been found growing on tree bark in various municipalities. The species has a broader distribution within Brazil, having been recorded from several states including Mato Grosso and Rio Grande do Sul. Leptogium chloromelum has also been documented in Peru.
