Filamentous terrestrial green alga with a worldwide distribution, growing on rocks, & tree trunks & branches, the orange color caused by large quantities of carotenoid pigments which mask the green of the chlorophyll; for more Orange Rock Hair (Trentepohlia aurea) growing nearby, cf. inaturalist.org/observations/215589888

I learned the rhyme "Sedges have edges, Rushes are round, Grasses have nodes all the way to the ground" (most of the time): joint-like nodes (where the leaf sheath ends) are found along round, hollow grass stems, stems of sedges & rushes are solid; in cross-section the stems of rushes are round, sedges are triangular (giving them edges, but they have no nodes, & triangular-stem sedges have 3-ranked leaves, leaves arranged on all 3 sides of the stem; like sedges, rush stems also have no nodes)... common names (some of the time) can confuse: Broomsedge is a grass, not a sedge; Bulrush and Woolgrass are sedges, not a rush, nor a grass

I like the neat rhyme "Sedges have edges, Rushes are round, Grasses have nodes all the way to the ground" (most of the time): joint-like nodes (where the leaf sheath ends) are found along round, hollow grass stems, stems of sedges & rushes are solid; in cross-section the stems of rushes are round, sedges are triangular (giving them edges, but they have no nodes, & triangular-stem sedges have 3-ranked leaves, leaves arranged on all 3 sides of the stem; like sedges, rush stems also have no nodes)... common names (some of the time) can confuse: Broomsedge is a grass, not a sedge; Bulrush and Woolgrass are sedges, not a rush, nor a grass

On a sweetgum seedball in muddy leaf litter; differentiating characteristics, many thanks to @pycnoporus: color and geography, plus N. niveotomentosa has white hairs, not orange, a west coast distribution, and brown periodoles (eggs), while the periodoles of C. laeve are white (not visible here in my images)
