Ciri dan struktur

The lichen forms an irregular rosette or spreading patch up to about 3 cm across. It is foliose, meaning the thallus resembles tiny, leafy rather than a crust. Those lobes are hollow, extremely fragile and measure 0.5–1.5 mm wide, branching in a rather untidy, forked fashion. Their upper surface ranges from off-white through grey-brown to almost black, often becoming glossy with age, and lacks any powdery soredia or finger-like isidia. Scattered oval to round perforations (0.1–0.6 mm) pierce the surface; their rims show flecks of the white inner tissue (medulla). Because the species is saxicolous (rock-dwelling), the entire thallus lies close against or slightly lifted from its substrate. Rounded fruit-bodies (apothecia) are frequent. They sit flush with, or a little above, the lobe surface and mature into discs up to about 0.7 mm across, with a dull brown-black interior ringed by a similar-coloured margin. Microscopic examination shows clavate asci that hold just two colourless, ellipsoid spores – each longer than 60 micrometres (μm) and often packed with tiny oil droplets. Chemical spot tests yield cortex K+ (yellow) and medulla K+ (yellow), confirming atranorin in the outer layer and a stictic acid complex in the medulla; reactions with C and KC are negative. Immersed flask-shaped pycnidia produce slender, rod-shaped conidia (4.5–7.5 × 0.7–1 μm) that provide a second means of asexual dispersal.

Habitat dan peran ekologis

Menegazzia fortuita is known to occur only in four sandstone outcrops in Morton National Park, south-eastern New South Wales. It grows on Hawkesbury sandstone blocks and ledges within open Eucalyptus woodland, conditions that provide intermittent shade, regular moisture from run-off, and a generally nutrient-poor, siliceous substrate. Associated lichens include rock-dwelling species of Buellia, Lecanora, Pertusaria, Ramboldia and Xanthoparmelia, indicating a community adapted to the exposed but not fully coastal sandstone environments of the Southern Tablelands. All collections lie within a relatively small area of the park, suggesting the species may be a local endemic.

Ringkasan sumber

Menegazzia fortuita is a species of foliose lichen in the family Parmeliaceae. Found in Australia, it was described as a new species in 2017 by lichenologists John Elix and Patrick McCarthy, it is known only from a few locations in Morton National Park in New South Wales, where it grows on sandstone in open Eucalyptus woodland. The species epithet fortuita refers to its fortuitous discovery during an unplanned field stop that helped resolve the identity of several previously unidentified specimens.
