Identification Key
1. Spores spheroidal, with reduced trilete marks, the proximal and distal connate-cristate surfaces indistinct
1. Spores tetrahedral, with a conspicuous trilete mark separating the triangular areas, well delimited at the equatorial region from the distal surface, often by a border free of ornamentations, ornamentation spinose, punctate, baculate, jagged, or lamellate
2
2. Thallus thickness of 10-20(30) cells, dorsal lamellae none to few; antheridial dimensions 100-150 um long, 60-85 um wide; sporophyte 20-100 mm long, 0.4-0.8 mm wide; spore distal face ornamentation of 15-18 spines and tubercles united at their base to form incomplete alveoli (perhaps non-native and possibly historically misapplied in some case)
2. Thallus thickness of 6-12(18) cells, dorsal lamella frequent, antheridial dimensions 56-88 um long, 45-56 um wide; sporophyte 8-20(30) mm long, 0.25-0.5 mm wide; spore distal face ornamentation with 7-12 spines
2
3. Spore distal face ornamentation of 8-12 spines with irregularly curved tips, coarsely reticulate and unlike below
3. Spore distal surface without reticulum, depressed areoles 3 um high, 7-9 groups of 2-4-fid spines 3 um high per diameter/spore; proximal trilete mark with aristae 2 um high without margin; triangular areas with depressions, without warts; distal reticulum with areolas smaller than 4 um
