Day 42: Hylocomium splendens ("Step Moss" or "Stairstep Moss") is one of the easiest Pacific Northwest bryophytes to identify. Its lacy foliage and unique growth habit are unlike those of any other moss in our area. It often forms dense mats on the floor of the lower forest, and only close examination will reveal its intricate beauty. Its name is derived from its pattern of growth. Each year, a new stem piggybacks on last year's, forming a long chain of "steps." Although usually only two or three tiers are readily visible, chains of 10 or more are not uncommon where this moss is abundant.
