Ciri dan struktur

The crustose thallus of Haematomma accolens ranges from thin to moderately thick, with a texture varying from smooth to slightly roughened or cracked. The thallus appears yellowish white to greenish-grey, occasionally showing darker tones. It lacks specialised reproductive structures like soredia or isidia. Occasionally, a white, fibrous Prothallus can be seen at the edges of the lichen. The apothecia, or spore-producing structures, are vivid red to deep reddish-orange and measure 0.6–1.5 mm in diameter. They are typically flat with smooth or slightly roughened margins that remain well-defined, sometimes becoming with age. The apothecial is smooth and never (dusty-looking). The hymenium (spore-bearing layer) is colourless, while the (uppermost layer of the apothecium) is orange, reacting purple in potassium hydroxide (K) before fading. The (layer beneath the hymenium) is pale yellow or colourless. Spores are long and spindle-shaped, measuring 36–68 μm in length and 3–5 μm in width, with 6–8 septa dividing them into sections. They are typically straight or slightly curved and align parallel in the ascus. Conidia (asexual spores), though rarely observed, are short and rod-shaped, measuring 5–7 μm long.

Habitat dan peran ekologis

Haematomma accolens grows on the deciduous tree bark in warm-temperate and subtropical regions. It commonly occurs on smooth-barked trees, including Quercus (oak), Acer rubrum (red maple), and Carya (hickory), but it is also found on other genera including Fagus (beech), Ilex (holly), Liquidambar (sweetgum), Magnolia, Nyssa (tupelo), Persea (bay trees), and Michelia. The species grows in shaded to semi-shaded forest environments. Haematomma accolens occurs mainly in the southeastern United States. It has been recorded from North Carolina to northern Florida, with scattered occurrences extending westward to eastern Texas. Beyond North America, the species is also known from the West Indies, Costa Rica, Guatemala, Brazil, parts of Africa, India, and northeastern Australia. Reports from Malaysia are tentative and require further verification. In Asia, it is known from Sri Lanka, and it was recollected in India after a gap of almost 136 years since its original type collection from the state of Assam. The lichen was recorded as new to China in 2019, at elevations ranging from 400 to 1230 m. Ecologically, H. accolens is part of lichen communities on tree bark, where it contributes to nutrient cycling and provides microhabitats for small invertebrates.

Ringkasan sumber

Haematomma accolens, commonly known as the tree bloodspot, is a species of crustose lichen in the family Haematommataceae. It forms thin to moderately thick patches on tree bark, appearing yellowish-white to greenish-grey in colour, and features vivid red to deep reddish-orange spore-producing structures (apothecia). The lichen typically grows on the bark of deciduous trees in warm-temperate and subtropical regions, particularly favouring smooth-barked trees such as oaks and maples in shaded forest environments.
