Bog Haircap Moss

Polytrichum strictum

Also known as Strict Haircap, Strict Haircap Moss, Bog Haircap

Dense, velvet-like hummocks of Bog Haircap Moss rise above soggy peat bogs, anchored by a thick white felt of rhizoids that insulates against freezing cold and moisture loss. Stem tops feature stiff, needle-like leaves that curl slightly when dry to conserve water during brief droughts. Male plants display distinctive reddish splash cups in spring that launch sperm toward female stems on falling raindrops.

Responsible observation
  • Magnification Check: Use a 10x hand lens to inspect the dense white rhizoid wool hugging the lower stem.
  • Habitat Tread: Stick to boardwalks in delicate peatlands to avoid trampling slow-growing moss hummocks.
  • Spore Capsule Observation: Look for tall reddish stalks topped with hooded spore capsules during midsummer.
