Leptogium menziesii

Ciri dan struktur

The thallus is about 7 cm across and 50–75 micrometres (μm) thick, brownish-grey in fluorescent light and greenish-grey under a stereomicroscope. Lobes are broad (to about 10 mm), overlapping and appressed; their tips are rounded and smooth, and the margins are thin and even. Isidia (tiny detachable outgrowths used for clonal spread) and (small flap-like propagules) are absent. Attachment is by abundant simple hairs that become "beard-like" as they agglutinate; the lower surface is (felted). The upper is a single layer of brick-like () cells; the lower cortex is likewise single-layered and felted. In section, the medulla shows the fungal hyphae compactly woven with the cyanobacteria; columnar (pillar-like) hyphae were not seen in the studied material, although the authors caution that rapid drying may have obscured them. Fruiting bodies (apothecia) of L. menziesii are small (to about 1.5 mm), and short-stalked. The apothecial discs are concave and their margins smooth to slightly wrinkled, without any or warting. The apothecial wall lacks a ; the (the tissue beneath the spore layer) is built of elongated cells (), whereas the parahymenial tissue is brick-like (). Ascospores were not observed in the material examined; in earlier work they were reported as having dimensions of 22–27 × 8–10 μm. Pycnidia occur on the thallus, usually near the margin, producing slender conidia about 3.75 × 1.25 μm. The bases of both apothecia and pycnidia are covered by hairs.

Habitat dan peran ekologis

Leptogium menziesii is subantarctic in character. The species was first collected in the Strait of Magellan area and is recorded from the Falkland Islands and South Georgia, with additional southern hemisphere records from Australia, Chile, Japan, New Zealand and Uruguay; other sources also list Peru. The lichen grows in dry herbfield and grassland, on or amongst bryophytes including Syntrichia robusta, Acaena magellanica, and Festuca contracta. In South Georgia it has been documented growing amongst Tortula robusta and, less frequently, in damp hollows on Chorisodontium and Polytrichum banks.
