Plants to 6 cm, often shorter. Stems with external cells in one layer, enlarged, reddish, walls firm, subtended by ca. 5 layers of small thick-walled reddish cells, internal cells larger, walls thinner, hyaline; pseudoparaphyllia narrowly to broadly foliose, when broad often incised; axillary hairs apparently 2 per axil (1 per axil in flagellate branch leaves), distal cell often with granular contents. Leaves 1-1.7(-2) mm; alar cells extending up margins 30-40 cells; laminal cells 6-8:1. Specialized asexual reproduction by flagellate branches to 4-5 mm, 70 µm diam. including leaves; leaves 0.2 mm, alar cells few, laminal cells 3-4:1.
