The Hookeriales are divided into five families, the Hookeriaceae, Daltoniaceae, Adelotheciaceae, Leucomiaceae and Callicostaceae. The families are delimited primarily on gametophytic characters, including several little-used ones, because the order is considered fairly uniform in peristome features except for a repeatable reduction of cross-striolate to papillose exostome teeth. The order and each family are described and generic inclusions listed. Discussion is presented for controversal genera. A dendrogram is provided to illustrate tentative relationships between the families.
