base of each bract, oval.

Found on the Continent and in North America.
Obs.— From all forms of Marsupella emarginata (Ehrt.) it may
be distinguished by its colour and lax texture and the narrow
decurrent base of leaf. ’
Marsupella sparsifolia, Lindb., approaches nearest to small
forms of M. sphacelata, but the former is paroicous
