Ciri dan struktur

Bacidina adastra is a crustose lichen characterized by its distinctive thallus (the main body of the lichen) that often forms extensive patches up to 0.5 metres in diameter. The thallus is thick and leprose (powdery), typically consisting of a cracked layer of soredia (specialized reproductive structures) up to 1 mm thick. When fresh, the thallus displays a vivid yellowish-green colour that resembles free-living green algae. When dried or in herbarium specimens, it tends to turn greenish-grey or brownish-grey. The individual soredia measure 30–50 μm in diameter. The photobiont (the algal partner in the lichen symbiosis) consists of chlorococcoid cells measuring 7–14 μm in diameter. Morphologically, B. adastra resembles B. neosquamulosa, a species complex that may include multiple distinct species. B. neosquamulosa in the strict sense forms imbricate, finely dissected microsquamules that may later disintegrate to form goniocysts. B. adastra, on the other hand, starts out as minute, somewhat flattened, granules that soon bud off new granules in a more or less coralloid manner, resulting in a thick, finely granular and pale green crust. In addition, the thallus surface tends to be more shiny in B. neosquamulosa than in B. adastra. Apothecia (fruiting bodies) are rarely present in Bacidina adastra. When they do appear, they are (attached directly to the surface without a stalk), constricted at the base, and measure (0.2-)0.4–0.7 mm in diameter. The disc of the apothecium ranges from flat to (wavy) and varies in colour from pale pink to dark blue-black, often with only partially coloured sections.

Habitat dan peran ekologis

Bacidina adastra has been documented in several Western European countries, including the Netherlands, Belgium, England, and Germany. Within the Netherlands, the species has been reported to be fairly common, with numerous putative specimens collected across different provinces including Drenthe, Noord-Holland, Overijssel, and Zuid-Holland. The first documented record of the species from eastern Europe was in Poland; it was later reported from Russia, Armenia, and Estonia. In Fennoscandia, it was first reported from Sweden in 2017, specifically from two sites in southern Skåne. Bacidina adastra is considered rare and strongly over-reported, as it is often confused with crusts of free-living green algae. The species occupies a variety of substrates, though it is primarily corticolous (growing on bark). It shows a preference for hypertrophicated (nutrient-enriched) bases of trees with neutral to basic bark, such as Populus (poplar), Salix (willow), and Ulmus (elm). It also colonizes trees with neutral to slightly acidic bark, including Frangula alnus (alder buckthorn) and Quercus robur (pedunculate oak). While primarily found on living trees, lignicolous (growing on wood), terricolous (growing on soil), and saxicolous (growing on rock) collections have also been documented.

Ringkasan sumber

Bacidina adastra is a species of corticolous (bark-dwelling) leprose lichen in the family Ramalinaceae. The lichen has a distinctive thick, powdery, bright yellowish-green thallus, forming patches up to half a metre in diameter. First described in 2003 from the Netherlands, it has since been documented throughout Western and Eastern Europe in countries including Belgium, England, Germany, Poland, Russia, and Sweden. The lichen primarily grows on tree bark, especially on nutrient-enriched bases of trees like poplar, willow, and elm, though it can occasionally be found on wood, soil, and rock.
