** Physcomitrium eurystomum subsp. acuminatum (Bruch & Schimp.) Giacom.
COMMENT
Excluded from Algeria.This taxon was reported by Bescherelle (1882) from Const. Sahara Mehounech, 390 m, under the name “ Physcomitrium acuminatum Schl. ”. Jelenc (1955a) while compiling previous northern African reports, considered that Bescherelle referred to a new undescribed taxon “ P. acuminatum Besch. non Schleich.” and put it as a synonym of Physcomitrium longicollum Trab. (synonymized by Ros & Cano (2008) with Entosthodon hungaricus). Therefore, it was not included in the Algerian checklists ofRos et al. (1999, 2013).
