Fissidens cyathaeicola Brugg. -Nann.

( Fig. 5 View FIG )

This relatively large species, 6.0 × 0.5 mm, is characterized by ½ limbate vaginant laminae, pluripapillose laminal cells and erect, narrow, undivided or irregularly divided peristomes with papillose filaments. In mats or scattered on bark of tree ferns.

Peristome

Slightly curved inwards when wet, stiff, undivided or irregularly divided.Teeth with short, up to 5 cells high, undivided part and a papillose distal part150 µm long, tooth base 30-32.5 µm wide, rudimentary second filament ( Fig. 5C View FIG ) occasionally present.

Ornamentation

OPL short, ±5 cells tall, undivided basal part with distinct, smooth trabeculae and ±smooth lamellae; the first cell above the bifurcation with distinct trabeculae and vertical walls and a sparse lamellar ornamentation; more distal cells densely and lowly papillose; IPL papillose throughout the teeth, IPL cells thicker than the thin, transparent OPL cells ( Fig. 5C View FIG ); filaments papillose.

Sporophyte

Seta 1.2-1.5 mm long, smooth; capsule 0.5 × 0.2-0.3 mm with exothecial cell columns 26-32, the cells thin-walled, oblong; operculum ± 0.2 mm long; spores 9.0-13.5 µm diam., papillose.
