Description
Genus Dicranoweisia
Plants densely tufted
, light to dark green, dull
. Stems 0.5-3 cm, erect
, forked
, with central strand, with rhizoids confined to base
of stems and firmly affixed
to substratum
. Leaves lanceolate, flexuose, crisped
or curled when dry, 1-3.5 mm; costa single, subpercurrent, narrow; margins
plane
to incurved
or recurved, 1- or 2-stratose; proximal
cells
elongate
, 15-30 µm, smooth
; alar cells
with a few enlarged cells on margins, often colored
or undifferentiated; distal cells subquadrate
7-10 µm wide, smooth or with longitudinal
cuticular ridges
. Specialized asexual
reproduction sometimes present, multicellular
, on abaxial
surface, elliptic
to short-linear, of 4-10 cells, 1-seriate or with occasional 2-seriate portions, smooth. Sexual condition autoicous
; pergonial leaves abruptly narrowed to a long or short subula; perichaetial leaves variable, resembling vegetative
leaves or broadly obtuse
to acute or short-acuminate. Seta solitary, yellowish, 3-15 mm, smooth. Capsule light to dark brown when mature
, elliptic to short-cylindric, 0.5-2 mm, smooth to longitudinally wrinkled when dry; annulus present, of 1-3 rows
of cells, deciduous or absent; operculum rostrate
, beak
straight or oblique
; peristome single, 16 teeth inserted
below darkened cells of mouth
, teeth entire to divided
at apices, red-brown with hyaline
tips
. Calyptra cucullate
, smooth, covering 1/3-1/2 of capsule, entire at base. Spores spherical
, 15-20 µm, weakly papillose
.
Species ca.
20: North America, South America, Europe, Asia, Africa, Pacific Islands (Hawaii, New Zealand), Australia, Antarctica.
Species of Dicranoweisia are usually epiphytic, epixylic, epilithic
, or terrestrial
and are found widespread throughout the world.[1]
Physical Description
Species Dicranoweisia crispula
Leaves crisped
and curled when dry, plane
in many leaves,
2-stratose in distal 1/2, cells
with longitudinal
striolae in distal
1/2 of leaf; usually a few alar cells
enlarged on margins
, often
colored
. Specialized asexual
reproduction absent. Capsule
without differentiated annulus; peristome vertically striolate
basally,
weakly papillose
distally. Capsules mature
spring-early summer. [source]
Dicranoweisia crispula is an extremely variable species. In
stature the plants
vary 1-6 cm, while the leaf length varies 1-3.5
mm.
The capsules vary considerably from cylindric
to short-elliptic,
with the length
ranging 0.5-2 mm. The shape
and sheathing
of the
perichaetial leaves is also variable. Although this species is autoicous
,
sex organs are often absent, especially in terrestrial
plants, with
sporophytes correspondingly infrequent. Differentiation
of alar cells
is often weak in North American material
and the striolation can
also be weak, and is best observed on cells adjacent
to the costa.

Habit: Nonvascular
Habitat
Forming cushions on siliceous rock or gravel , occasionally epiphytic or epixylic; 10-2000 m [2].
Typically found at an altitude of 0 to 4,701 meters (0 to 15,423 feet).[3]
