Genera ca. 13, species ca. 300 (6 genera, 29 species in the flora ) : worldwide except Antarctica.
The Funariaceae is characterized by broad leaves, large, pale laminal cells, opposite peristomes, and the distinctive stomata. The majority of species are found in disturbed or open sites on bare soil. Many of the species are annuals or biennials, and some may be perennials . When sterile , only a few species have distinctive vegetative features that allow positive identification to genus or species level. Fortunately most are usually fertile and sporophytes are common, although seasonal.
Plants small, scattered
. Stems 2-10(-25) mm, erect
. Leaves crispate
to contorted when dry, erect to spreading
when moist, ovate-lanceolate, ovate
, to obovate
, sometimes concave
, 1.2-5 mm; margins
entire to serrulate
distally; apices somewhat blunt
, or acute to acuminate; costa single, subpercurrent to short-excurrent; proximal
elongate-rectangular to rectangular, distal cells rectangular to hexagonal. Sexual condition autoicous
, occasionally polygamous; perigonia at apices of short basal or lateral
branches, usually with clavate
paraphyses; perichaetia at stem apex, with a few filiform
paraphyses. Seta erect, 0.5-13(-30) mm.
, erect, immersed
to exserted, symmetric
, or campanulate
, often urceolate
when dry, mouth
, 0.8-3 mm, smooth
, neck usually wrinkled when dry; exothecial cells irregularly isodiametric, hexagonal, or oblong
, sometimes collenchymatous; a few stomates usually present in neck, superficial; annulus narrow, consisting of 1-2 rows
of small cells or revoluble
as fragments of large cells; operculum convex
to conic, apiculate
; peristome absent. Calyptra mitrate, deeply split into (2-) 3(-4) spreading lobes, long-rostrate, sometimes inflated
at the base
, usually large, smooth. Spores spherical
to sub-reniform, papillose
Species ca. 80: temperate North America, Mexico, Central America, South America, Europe, Asia, Africa, Australia.
Physcomitrium is characterized by erect, symmetrical , and often urn-like capsules that lack peristomes. Infra-species variation of both the sporophyte and gametophyte of Physcomitrium pyriforme has led to many species being described over time in North America.
Physcomitrium commonly occurs on exposed soil often associated with spring-wet sites, often on alluvial mud and river banks, from near sea level to ca. 2500 m , and the capsules mature over winter into spring .
Species Physcomitrium pyriforme
Plants light green or yellowish green. Stems 0.2-15(-25)
cm. Leaves obovate
to ovate-lanceolate, distal leaves 2-5
, sometimes nearly smooth
to rarely short-excurrent. Specialized asexual
absent. Seta (1-) 6-15(-30) mm.
Capsule exserted, 1-3
mm, globose-pyriform when young, highly variable in shape
; neck short, distinct
; exothecial cells
hexagonal; suboral cells consisting of 5-17 rows
of rectangular cells.
Spores (24-) 46-60(-90) µm, papillose
. Capsules mature
late fall-spring. [source]
Physcomitrium pyriforme is morphologically variable and widespread across the continent. Plant size, leaf characters, and shape of the capsule vary from place to place and often within populations. [source]
Wet soil in disturbed places; low to high elevations .
Typically found at an altitude of 0 to 4,701 meters (0 to 15,423 feet).
