Inoderma subabietinum

Ciri dan struktur

The thallus (lichen body) forms extensive, whitish to pale olivaceous-grey patches that may remain continuous or crack into small, angular plates (). It lacks a true outer cortex (it is ), giving it a , faintly scurfy, minutely appearance. In cross-section it is thin (to about 0.12 mm) and partly sunk into the outer bark. The is a Trentepohlia-type () green alga. Its cells mostly measure 7–15 × 4–13 μm. Calcium oxalate crystals were not observed. Sexual fruiting bodies (apothecia) are unknown. Asexual fruiting bodies (pycnidia) are numerous and conspicuous: dark brown to black, cup-shaped structures 0.20–0.45 mm across. Their rims and upper sides are coated in a thick, coarsely granular white (a frost-like powder). The opening ranges from narrow to widely gaping, and the rim is often strongly reflexed (curved backwards). In cross-section the cavity is bowl-shaped to wedge-shaped (about 100–300 μm wide) and may be divided by thin internal septa; the wall is . Conidia are rod-shaped (), usually 4.2–5.8 × 1.1–1.5 μm (rarely up to 7.0 × 1.7 μm; mean about 5.0 × 1.3 μm). Chemically the species contains confluentic and lepraric acids. In spot tests, the thallus and pycnidial pruina are K+ (lemon yellow), but C−, KC− and Pd−; the thallus hyphae are I+ and KI+ (pale blue). The crystal layer of the pycnidia dissolves in K (potassium hydroxide; yellowish solution) and in lactic-cotton blue, but not in sulphuric acid.

Habitat dan peran ekologis

Inoderma subabietinum is a strongly oceanic lichen (associated with Atlantic climates) of dry, acidic substrates, usually found in sheltered situations that are semi-shaded rather than deeply shaded. It is most often recorded on the bark of old oaks (Quercus), but it has also been found on Betula, Pinus and Hedera. More occasional records are from Calluna stems and decaying fern fronds in sheltered sites. It can grow alongside other oceanic bark lichens such as Arthonia impolita, Diploicia canescens, Enterographa crassa, Lepraria incana, Schismatomma decolorans and Chaenotheca hispidula. The similar Opegrapha vermicellifera tends to occur in shadier conditions and on less acidic, more nutrient-rich bark, for example on Acer pseudoplatanus and Ulmus. In Great Britain it is considered easily overlooked and has been recorded mainly from southern, oceanic areas. Confirmed records include Great Britain and Ireland, France (including Brittany), and the Atlantic island groups (archipelagos) of the Azores, Madeira and the Canary Islands.
