NOTE
Designation of a
lectotype
for
Porphyra linearis
Greville
from a specimen from Sidmouth at E by
Brodie & Irvine (2003: 124)
was not valid as the phrase “designated here” or an equivalent was not used as required after
1 January 2001
(Art. 7.11;
Turland
et al.
2018
). We here designate formally the same specimen (‘Sidmouth, Spring’, E!) as
lectotype
.
