Bryoandersonia illecebra

Worm moss, a pleurocarp 

A common alkaline soil mat forming species, but not clump, peristome seldomly described with a rare chance of seeing a beaked operculate cap.  Wet specimens are often erect, dry tend to flop over and form more prostrate looking growth; however, all of these individuals are legitimately prostrate. Microphyll cymbiform(boat shaped), acuminate tips with glabrous appearing margins, 4x on a scope reveals  micro serrate margins, mid rib ends below tip. These require mesic alkaline forest floors to truly proliferate.

Moss: Pleurocarps vs. Acrocarps

Pleurocarpous

• grows low and wide

• spreads quickly

• good on hard surfaces like limestone

• low maintenance (can be completely submerged in water)

• doubles in size in 6 months

Acrocarpous

• grows high and clumps

• spreads slowly

• weeds are less likely to invade due to tight clumps

• needs to periodically dry out to prevent from rotting

• takes 2 years to be considered "a carpet of moss"
