Porpidia macrocarpa

Ciri dan struktur

Porpidia macrocarpa is a crustose lichen with a variable thallus, typically appearing (embedded in the ) to thin and continuous, but it can sometimes be thicker and become cracked () or divided into small sections (). The surface of the thallus is rough and web-like () with a colour range from pale grey to greenish-grey. It frequently shows patches or continuous areas of orange to rust-red due to oxidation. The medulla (internal tissue) does not react to iodine (I–). The (initial growth stage) is indistinct at the margins of immersed thalli but becomes wavy, black, and somewhat distinct at the margins of more superficial thalli. The apothecia (fruiting bodies) are up to 3 mm in diameter, usually (sitting directly on the thallus), abundant, and can be scattered or crowded together. They are constricted at the base with a thick, swollen (rim) that is persistent, black, shiny, and raised, ranging from entire to somewhat wavy (). The hyphae (filamentous fungal cells) measure 3–9 μm in diameter. The of the apothecia can be slightly concave to flat or convex, black or brown-black, with a or shiny finish, and sometimes covered with a grey powdery coating (). Larger apothecia often appear to divide through the formation of secondary margins within the disc. The (upper layer of the hymenium) is pale brown to olive-brown, and the hymenium (spore-producing layer) measures 80–100 μm tall. The (layer below the hymenium) and inner exciple may show a reddish tinge when treated with potassium hydroxide solution (K+). The are elongated, measuring 16–20 μm in length and 6–11.5 μm in width. The medulla reacts variably to chemical spot tests, sometimes showing a yellowish reaction with potassium hydroxide (K±) and an orange reaction with p-phenylenediamine (Pd±), indicating the presence of stictic and cryptostictic acids.
