Lichenomphalia meridionalis

Ciri dan struktur

The thallus of Lichenomphalia meridionalis is a Botrydina-type structure consisting of small green to dark-green globules, typically 20–55 micrometres (μm) in diameter but sometimes reaching 80 μm. Each globule contains Coccomyxa algae cells enclosed by fungal hyphae. The basidiomata (fruiting bodies) are small and omphalinoid in shape. The caps are 3.5–10 mm wide, convex to flattened or slightly depressed, and translucent-striate. They range in colour from ochraceous to yellowish red, light brown, or brown, and often become paler with age or when dried. The gills are widely spaced (distant) and run down the stem (decurrent), typically whitish to pale greyish white or sometimes matching the cap colour. The stipe (stem) is slender, 5–20 mm long, covered in fine short hairs (densely velutinous or pubescent), and white-tomentose at the base where it connects to the thallus. Under the microscope, the pileipellis (cap surface) consists of cylindrical hyphae with club-shaped (clavate) tips, arranged in a cutis to subtrichodermium (a layer of hyphae lying flat to slightly upright). Cystidia are absent, and the basidia (spore-bearing cells) are mostly four-spored, though they may also bear two spores or, rarely, just one. The basidiospores are colourless (hyaline), thin-walled, inamyloid (not staining with iodine), and ellipsoid to cylindrical or elongate in shape, with a prominent apiculus (a small projection at the point of attachment). Most tissues lack clamp connections, though specimens from Japan have shown them in some of the hyphae connecting thallus globules. A diagnostic feature of L. meridionalis is the faintly encrusting pigment of the pileipellis, which does not form the dark zebroid stripes seen in L. velutina.

Habitat dan peran ekologis

Lichenomphalia meridionalis grows on bare or mossy acid soil, often on slopes, road banks, or open ground in oak woodland and shrub vegetation, including sites with Cistus, Calluna vulgaris, Quercus pyrenaica, and Quercus ilex. In the Iberian Peninsula it has been treated as a Mediterranean species of humid montane sites, especially in the mesomediterranean and supramediterranean elevation belts, and Spanish material studied for symbiont composition came from 533 to 2,200 m elevation. Fruiting bodies have been recorded in cool, moist parts of the year, especially winter, spring, and autumn. The species was first described from Sardinia and is now known from Spain, Corsica, Greece (Lesvos), and central Japan, where it occurs on Andosols along montane to subalpine road banks at about 1,200–1,900 m elevation. It was documented for the first time from Middle Europe in 2020, when it was recorded from Hungary. A study of Spanish populations found that the fungus associates with two strains of Coccomyxa subellipsoidea that are distributed in part by altitude, and that one of those algal strains consistently occurred with cyanobacteria in the thallus.
