Species description: Species name describing the shining, brightly coloured plants.
Reproduction: Sporophytes frequent, red-brown, with long-cylindric, suberect sporangia, maturing in late winter to spring.
Comments: H. lutescens, a European species, was once considered to be identical to H. fulgescens.
Distinguishing characteristics: The usually irregularly branched, coarse plants that produce long-cylindric, somewhat curved sporangia, the pleated leaves and the usual habitat on tree trunks are useful features to separate this species.
Habit: Forming interwoven mats of yellow-green to dark green, glossy, creeping, much-branched plants 50-170 mm long; usually attached to substratum by red rhizoids. Leaves strongly pleated with the midrib resembling a central pleat. Plants not curling upward markedly when dry.
Similar Species: The irregular branching and the usual coarseness of the plants are enough to separate H. fulgescens from H. nuttal/ii. On populations on rock, the sporophyte shape distinguishes H. fulgescens from H. aeneum in which sporangia are short-cylindric and bent at a sharp angle at the seta apex. H. nevadense of the interior has erect sporangia, which mature in summer rather than spring, but the plants are on shaded cliffs and usually are formed of densely compacted branches that form a turf-like mass over the substratum.
Habitat / Range
Predominantly on living tree trunks and branches (especially broad-leafed maple), also on rock and rarely on stabilized sand.
Confined to western North America from southeastern Alaska to California and eastward to western Montana.
