Haematomma sorediatum

Ciri dan struktur

Haematomma sorediatum forms a pale white to grey (sometimes greenish-grey), crust-like thallus (the lichen body) with a granular to slightly warty () surface. It reproduces asexually by producing soredia in discrete, round soralia that are usually raised into small domes; in older thalli, neighbouring soralia may merge. A thin, white, fibrous (a border at the thallus edge) may be present. Apothecia (fruiting bodies), when present, are in form and usually about 0.6–1 mm in diameter (occasionally larger). They have a bright red to orange-red and a persistent margin that is often (scalloped) and may become partly sorediate. The disc is often (lacking a powdery coating), though some collections have been described as having a light . Asci contain eight colourless (hyaline) ascospores. Across published accounts, the spores are long and narrow (about 40–70 × 4–7 μm) and divided by about 7–14 transverse septa (cross walls). They have also been described as helically coiled within the ascus. Reported chemistry includes atranorin and placodiolic acid. In the K spot test (potassium hydroxide), the thallus typically turns yellow (K+), and the apothecial pigment briefly turns purple before fading.

Habitat dan peran ekologis

Haematomma sorediatum is a bark-dwelling species with a distribution that has been described as widely pantropical (recorded across tropical regions). In the Asia–Pacific region it is known from Australia, New Zealand, and New Guinea. In Australia it is documented from south-eastern Victoria, including the type locality, where it has been collected on Notelaea ovata and Pomaderris apetala. It was later reported from Maria Island National Park (Tasmania), based on a March 1981 collection at about 300 m altitude. The specimen grew on the trunk of P. apetala in a humid creekline forest with Eucalyptus viminalis and Acacia melanoxylon. The species may be overlooked and may occur more widely where this host is present in eucalypt forests. It was later recorded from Stony Head in northern Tasmania. In New Zealand, it has been reported as common in the northern North Island (north of about 38°S). A separate (disjunct) record is also known from near Puponga in the north-west of the South Island, on the bark of several woody hosts including Rhopalostylis, Phyllocladus, and tawa. It has also been recorded from New Guinea, in primary (old-growth) mountain forest at 2300 m elevation. In the Americas, H. sorediatum has been reported from the West Indies and has been confirmed from Jamaica.
