Nomenclature: Current taxonomic status: accepted. Taxonomic rank: species. Cladonia. Cladoniaceae Zenker (1827).

Taxonomic Literature: Brodo I.M. & Ahti T., Can. J. Bot. 74: 1147-1180 (1996).

Ecology: Terricolous, bryophytic (especially stumps and logs), or lignicolous; growing sun-exposed, partially shaded, or fully shaded.

Thallus: Crustose, squamulose; lobes ascending or horizontal; branches densely aggregated, scattered, loosely aggregated, or clustered; separate thallus parts 2-10 mm long; 1-7 mm wide. Primary Thallus: Persistent. Secondary Thallus: Present, arising from center of the primary thallus or arising from edge of the primary thallus, of determinate growth; stipe 10-40 mm high, 1-2.5 mm wide, lime green, homogeneously coloured, corticate (but podetia sometimes largely decorticate), with intact or longitudinally split wall. Thallus Outline: Margin crenulate or dissected. Upper Surface: Areolated (above), lime green (yellow-green (122-123), often maculate and sometimes scabrose), smooth (at base, broken into irregular "plates"); not sorediate. Lower Surface: White or orange (at dying base).

Lower Cortex: Absent.

Ascocarps: Forming apical at the tip of branches or stipes or along the margin of scyphi, moderately abundant, .5-3 mm in diam.. Disk: Weakly convex to strongly convex; red.

Conidiomata: Formed on margins of scyphi.

Secondary Metabolites: Thamnolic acid (with decarboxythamnolic acid) and usnic acid, of the following substance class(es): ß-orcinol depsides.

Spot Tests: Upper surface: K + deep yellow, C –, + deep yellow, or + orange, PD + orange.
