Ciri dan struktur

Peltula euploca is a squamulose cyanolichen with a distinctive (shield-like) thallus. Individual peltate are usually only a few millimetres across but can reach about 12 mm in diameter in well-developed material. The upper surface is dull to slightly shiny olive to olive-brown when moist, becoming darker and browner when dry, and the margins are often bent downwards or somewhat . The squamule edges carry bluish-grey (floury) soralia that are normally on the margins but can extend onto the upper surface; the resulting soredia are the main means of vegetative reproduction, as apothecia are infrequent. The lower surface is paler and lacks rhizines, and the thallus is attached at a single central (a holdfast) that anchors it tightly to the rock. Its apothecia (sexual fruiting structures) are rarely seen. When present, they appear as tiny immersed in the thallus surface. The discs are reddish, brown, or black. Inside each apothecium, the asci are club-shaped and polysporous – containing dozens of ascospores (typically 32 to over 100 per ascus, rather than the usual 8). The ascospores are hyaline, ellipsoid to rod-shaped, about 6–9 micrometres (μm) long by 3–5 μm wide. P. euploca also has tiny pycnidia (asexual spore-producing structures) immersed in the thallus; these produce slender fusiform (spindle-shaped) conidia about 3 × 1 μm. In cross-section, P. euploca has a thin upper of dead cells but no true upper . Beneath this is a distinct (about 70–150 μm thick) containing a zone of unicellular cyanobacteria, and a medulla with loosely woven hyphae and many air spaces. A well-developed lower cortex (18–90 μm thick) of tissue is present on the underside, except at the central attaching point.

Habitat dan peran ekologis

Peltula euploca is an arid-land saxicolous lichen that grows on rock surfaces. It grows on acidic rocks and only rarely on calcareous substrates. The typical habitat is open, dry terrain – for example, sun-exposed boulders and outcrops in deserts, semi-deserts, and other sparsely vegetated areas. In the American Southwest, it occurs on non-calcareous rock in extremely dry sites, but it can also occupy somewhat shaded or intermittently damp microhabitats such as canyon walls that remain arid most of the time. In the Upper Douro valley of north-east Portugal, P. euploca is common on vertical schist outcrops in hot, dry Mediterranean river gorges, where summer temperatures can approach 50 °C and annual rainfall is often below 300 mm. There it colonises almost all sheltered to fully exposed schist faces and is a dominant species in siliceous "rain-track" lichen communities on seepage tracks of the rock walls. In the Côa Valley (Portugal) it forms widespread squamulose populations on vertical schist surfaces. With a cosmopolitan distribution, Peltula euploca is the most widespread species of Peltula: it has been recorded from all continents except Antarctica and is especially common in subtropical and tropical arid regions.

Ringkasan sumber

Peltula euploca, the powdery rock-olive, is a species of lichen-forming fungus in the family Peltulaceae. First described in 1799 by the Swedish lichenologist Erik Acharius, the species was later transferred through several genera before molecular studies confirmed its placement in Peltula, the sole genus in Peltulaceae. Its overall appearance is that of a powdery-edged, olive-green rosette closely pressed to the substrate. In dry conditions it often becomes dull and brownish but can quickly rehydrate and turn green when moistened.
