Poor pocket moss
Fissidens pauperculus
Fissidens
pauperculus
A member of the family Fissidentaceaea, the only genus is Fissidens. Referred to by the generic common name “fissidens moss”, F. pauperculus is one of eight mosses in this genus in BC. More common in California and Oregon, overall it is uncommon across its global range.
A somewhat diminutive moss, male and female reproductive parts occur on the same plant. The 6-10 leaves, arranged in 3-5 pairs are 1.5-2.5 cm long and 0.3-0.4 mm wide. Leaves are similar in appearance whether wet or dry and partly folded to the base (another distinctive characteristic of this genus). These folded portions average one-half to two-thirds the length of the leaf. The leaf mid-rib ends 6–15 cells below the apex (most other moss species have longer mid-ribs). The spore capsules are at the end of a 2-3 mm stalk which is yellow when young, becoming reddish with age. Capsules are ovoid to oblong-ovoid and inclined to slightly bent.
