Astrothelium aeneum

Ciri dan struktur

Astrothelium aeneum has a (having a cortex-like structure) thallus, which typically appears as a light olive-green to yellowish colouration. Much of its surface is often covered with a distinctive orange pigment. The texture of the thallus ranges from smooth to uneven. The ascomata, or spore-producing structures, are of the type, characterised by their apical ostioles (small openings). These ascomata are generally found either solitarily, irregularly merging with each other, or spreading diffusely in a pattern. Their size varies from 0.3 to 0.7 mm in diameter. They are , meaning they break through the thallus, and are covered by both the thallus and orange pigment, except for the darker area around the ostioles. The , the supportive tissue structure containing the asci, is clear. Each ascus typically contains eight ascospores. These spores are (spindle-shaped), with a size range of 20–27 μm in length and 7–10 μm in width. They are hyaline (translucent) and have three septa (internal partitions). They do not react to staining with iodine (IKI−). Chemically, both the thallus and ascomata of Astrothelium aeneum react to ultraviolet light by fluorescing red (UV+ red) and produce a purple reaction when treated with potassium hydroxide (K+ purple). This is indicative of the presence of an anthraquinone, a type of chemical compound.
