1	"Leaves with hyaline awns, wrinkled but not plicate when dry"	2
2	"Median leaf cells with unbranched papillae that appear circular to short-elliptic from surface view; awn long and flexuose, often caducous in older leaves, uniseriate for most of its length; capsule exserted"	"Pseudobraunia californica"
2	"Median cells with branched papillae that appear stellate in surface view; awn decurrent and not flexuose or caducous, several cells broad to near the apex; capsules immersed"	3
3	"Abaxial surface of some of the upper laminal cells with more than 2 papillae; apical cell of awn usually truncate and coronate papillose"	"Hedwigia ciliata"
3	"Abaxial surface of upper laminal cells consistently with only 1-2 papillae; apical cell of awn pointed with papillae seriate"	4
4	"Perichaetial leaves without marginal cilia; awns of vegetative leaves serrulate or even entire, never spinose on dorsal surfaces; the perichaetial leaves abruptly larger than the vegetative leaves of adjacent branches"	"Hedwigia detonsa"
4	"Perichaetial leaves with ciliate margins; dry plant with awns of vegetative leaves erect or nearly so; awns of vegetative leaves with spinose teeth both on the margins and on the dorsal surfaces; the large perichaetial leaves only gradually differentiated from the smaller vegetative leaves"	"Hedwigia stellata"
