The plants may be soft or rigid; the stem cortical cells have somewhat firm walls. The leaves are not plicate; the basal laminal cells are pale and smooth with walls thin or rarely thick toward the costa. The perichaetial leaves are usually less prorulose with more lax areolation; the exostome teeth are sometimes cleft distally and lack intermediate abaxial thickenings. <i>Bartramia stricta</i> lacks a sheathing leaf base but otherwise is in accord with the generic concept.</p> |tables= |references= }}<!-- --><div class="treatment-key"> ==Key== <div class="treatment-key-group"> {| class="wikitable fna-keytable" |-id=key-0-1 |1 |Leaves 4-7 mm; bases laxly or scarcely sheathing; stems to 10(-15) cm |[[#key-0-2| > 2]] |-id=key-0-1 |1 |Leaves usually 1.5-5 mm; bases sheathing (except B. stricta); stems to 5 cm |[[#key-0-3| > 3]] |-id=key-0-2 |2 |Setae short, equal to or slightly longer than capsule. |[[Bartramia halleriana|Bartramia halleriana]] |-id=key-0-2 |2 |Setae many times longer than capsule. |[[Bartramia pomiformis|Bartramia pomiformis]] |-id=key-0-3 |3 |Leaf bases not sheathing, shoulders absent. |[[Bartramia stricta|Bartramia stricta]] |-id=key-0-3 |3 |Leaf bases sheathing, shoulders well developed |[[#key-0-4| > 4]] |-id=key-0-4 |4 |Costae obscure in distal limb; distal laminal cells 25-45 µm, prorulae low. |[[Bartramia ithyphylla|Bartramia ithyphylla]] |-id=key-0-4 |4 |Costae prominent in distal limb; distal laminal cells 8-25 µm, prorulae high |[[#key-0-5| > 5]] |-id=key-0-5 |5 |Leaf shoulders delicate, often eroded; apices fragile, usually broken. |[[Bartramia potosica|Bartramia potosica]] |-id=key-0-5 |5 |Leaf shoulders firm, not eroded; apices usually intact |[[#key-0-6| > 6]] |-id=key-0-6 |6 |Basal laminal cell walls thick toward costa, thin toward margins; leaf margins strongly revolute. |[[Bartramia brevifolia|Bartramia brevifolia]] |-id=key-0-6 |6 |Basal laminal cell walls thin throughout; leaf margins plane distally. |[[Bartramia subulata|Bartramia subulata]] |} </div></div><!-- -->{{#Taxon: name=Bartramia |authority=Hedwig |rank=genus |parent rank=family |synonyms= |basionyms= |family=Bartramiaceae |distribution=Nearly worldwide;except Antarctica;especially diverse in montane tropics. |reference=None |publication title=Sp.
