Protoparmeliopsis achariana

Ciri dan struktur

Protoparmeliopsis achariana is characterised by its distinctive thallus (the main body of the lichen), which grows in rosette or cushion-like formations. The thallus displays a pale yellow to yellow-green or grey-white colouration. In the central region o the thallus, the often grow slightly upward, overlapping each other and maintaining a loose attachment to the substrate. The marginal lobes measure between 0.8 and 1.5 mm in width (occasionally reaching up to 2 mm), and are white on their underside. These marginal sections lack a distinct border (non-marginate) and appear flat to slightly convex in shape. The species typically produces abundant apothecia (disc-shaped fruiting bodies), measuring 1 to 2 mm in diameter. These reproductive structures are (attached directly to the thallus) or have short stalks. The (the rim of tissue surrounding the apothecium) develops a (finely scalloped) and wavy appearance over time. The central of the apothecium ranges in colour from pale grey-brown to pinkish brown, and may appear greenish when growing in shaded conditions. The disc surface lacks (a powdery or frosted coating). Microscopic examination reveals (spores produced in specialized cells called asci) measuring 10 to 15 micrometres (μm) in length (occasionally reaching 16 μm) and 4 to 6 μm in width. Chemical spot tests commonly used to identify lichens show that the medulla (inner layer) of P. achariana is C−, Pd−, and typically K−, though rarely it may turn yellow then red (K+ yellow→red). The thallus does not fluoresce under ultraviolet light (UV−). Chemical analysis indicates the presence of zeorin, usnic acid, and unidentified triterpenoids.

Habitat dan peran ekologis

Protoparmeliopsis achariana is a species of saxicolous (rock-dwelling) crustose lichen in the family Lecanoraceae. It grows on siliceous rocks in the United Kingdom, where it is rare. Protoparmeliopsis achariana is characterised by its distinctive thallus (the main body of the lichen), which grows in rosette or cushion-like formations. The thallus displays a pale yellow to yellow-green or grey-white colouration. In the central region o the thallus, the often grow slightly upward, overlapping each other and maintaining a loose attachment to the substrate. The marginal lobes measure between 0.8 and 1.5 mm in width (occasionally reaching up to 2 mm), and are white on their underside.
