Ciri dan struktur

Gyalideopsis macarthurii forms a thin, crustose (crust-like) thallus on bark. The thallus is continuous, measuring 5–10 mm across and only 10–20 μm thick, with a outer layer. Its surface is irregularly warty () due to clusters of calcium oxalate crystals. The lichen is pale greenish-grey in colour and has a shiny () appearance. The photosynthetic partner () of the lichen consists of green algae () with cells measuring 5–9 μm in diameter. The reproductive structures (apothecia) are distinctive for this species. They emerge from the surface (), are round in outline, and measure 0.15–0.25 mm in diameter and 70–90 μm in height. The disc is flat and dark greyish brown with a coarse, white to pale grey powdery coating (). The (edge) of the apothecia is inconspicuous and covered by 4–6 triangular, thin, pale grey, thalline lobules that lack algal cells. The spore-producing layer (hymenium) is colourless and 50–60 μm high. The spore sacs (asci) are broadly club-shaped, measuring 45–55 by 20–25 μm. Each ascus produces a single, ellipsoid spore that is (divided by both longitudinal and transverse walls), with slight constrictions at the dividing walls. The spores measure 35–40 by 12–18 μm, are 2.5–3 times as long as broad, and are colourless. The (specialized asexual reproductive structures) are distinctive, being shortly bristle-shaped with a pointed tip, measuring 0.04–0.06 mm high and 10–12 μm thick above the base. They are blackish brown with a pale base. The (specialized hyphae inserted at the apex of hyphophores) are branched throughout, shallowly (resembling a string of beads), with segments broadly club-shaped or drop-shaped to ellipsoid, measuring 4–6 by 2–2.5 μm.

Habitat dan peran ekologis

Gyalideopsis macarthurii was initially discovered in Costa Rica, where it was found in the Volcán Tenorio National Park (Pilón Biological Station) in the Cordillera de Tilarán region. The species inhabits lower montane cloud forest zones at an elevation of approximately 700 meters above sea level. The lichen has been collected growing on wet, rotting logs and on the bark of lower tree trunks in exposed areas along pastures. These habitats are characteristic of edges between forest and cleared land in the montane regions of Costa Rica, suggesting the species may prefer slightly disturbed environments with high humidity. The geographic range of the species was later expanded when it was recorded from Florida, USA in 2007, and subsequently from Brazil in 2023. G. macarthurii remains one of 27 Gyalideopsis species that have been reported from Costa Rica.

Ringkasan sumber

Gyalideopsis macarthurii is a species of corticolous (bark-dwelling) crustose lichen in the family Gomphillaceae. The pale greenish-grey lichen forms thin, shiny crusts on bark and rotting logs in montane cloud forest environments, particularly in exposed areas along forest edges and pastures, and has been documented in Costa Rica, Florida, and Brazil. It is distinguished by its distinctive fruiting bodies with thin triangular lobes covering the margins, extremely small specialized reproductive structures called , and its habit of growing on bark rather than leaves, which separates it from its closest relative, Gyalideopsis lobulata.
