REMARKS

Because of the longly excurrent costa (often up to 1 mm), all specimens have been referred to var. piliferum , though the rectangular superficial ventral cells of the costa may indicate a closer relationship to var. cuspidatum (Flora Briofítica Ibérica III: 177ff.). Phascum cuspidatum has been included in the Red Data Book by Lanfranco (1989: “not recorded since 1876...”), and Frahm & Lüth (2008) found it twice (one cited as P. cuspidatum , the second as var. piliferum ).
