Ciri dan struktur

The lichen forms a leafy (foliose) thallus with narrow, strap-like , usually arranged as rounded rosettes that can reach about 15 cm across and may merge into larger, irregular patches. The upper surface is light to dark olive-brown, sometimes becoming nearly blackish, and it is dotted with tiny pinhole-like breaks (pseudocyphellae) that can later open into cap-like powdery structures (capitate soralia) that produce soredia. The lobes are often crowded and overlapping toward the center but become more distinct near the margins, where they may broaden and branch into smaller . The lower surface is black, with a brown edge, and it is attached by coarse, mostly simple or forked rhizines that can be up to about 1.2 mm long. Apothecia (fruiting bodies) are often present, reaching up to about 7 mm across, with a red-brown to dark brown-black and a thallus-colored margin that may develop soralia or become covered in soredia. The ascospores are ellipsoid and typically measure about 8–11 × 4–6.5 μm, and pycnidia were reported as uncommon, producing slender, colorless conidia about 5–8 × 0.8–1.5 μm. Standard spot tests reactions include a usually negative K reaction and a C reaction that is sometimes rose-pink in the and rose-pink in the medulla, consistent with the presence of gyrophoric acid. In a modern molecular context, Leavitt and coworkers emphasized that North American sorediate material matching the type concept is best treated as M. saximontana, even when it is otherwise difficult to separate from Asian M. tominii-like specimens using appearance alone.

Habitat dan peran ekologis

In the original description, the species was primarily saxicolous and recorded from a wide range of rock types, including rhyolite, granite, gneiss, schist, noncalcareous to somewhat calcareous sandstones and conglomerates, and even strongly calcareous red shale. It can partly overgrow moss mats, and at and near the type locality it was also found occasionally on bark and wood of Douglas-fir (Pseudotsuga menziesii) and ponderosa pine (Pinus ponderosa), with one record from juniper wood. In the Colorado Front Range, Anderson and Weber reported that it overlaps altitudinally with Montanelia disjuncta from about 6000 to 10000 ft, with M. disjuncta more frequent above 10,000 ft and M. saximontana more frequent below 6,000 ft. They also noted substantial variation in growth form (from tightly appressed, densely (overlapping) thalli to more open, flattened, branched thalli) and interpreted this as environmental variation rather than taxonomically meaningful differences. Anderson and Weber reported it from multiple western U.S. states, including Arizona, Colorado, Montana, New Mexico, South Dakota, and Utah, based on a large series of collections assembled since 1950. In Leavitt and coworkers' revision, M. saximontana was treated as restricted to western North America and supported as a distinct lineage using ITS sequence characters and multilocus analyses.

Ringkasan sumber

Montanelia saximontana is a species of foliose lichen in the family Parmeliaceae. It is characterized by its olive-brown, leafy growth form with powdery reproductive structures (soredia) and a black underside. The species grows on rocks and occasionally on tree bark across western North America, from British Columbia south to Arizona. Originally described from specimens collected in Colorado in 1962, it was transferred to its current genus in 2016 based on DNA evidence. It is closely related to the Asian species Montanelia tominii and can only be reliably distinguished from it using DNA sequences.
