Cryptolophocolea L.Söderstr., Crand. -Stotl., Stotler et Váňa, gen. et stat. nov.

Type:— Cryptolophocolea ciliolata (Nees) L.Söderstr., Crand. -Stotl., Stotler et Váňa.

Description:—Plants lophocoleoid in aspect; leaves opposite to subopposite, bifid, often with the ventral lobe larger than the dorsal; underleaves large, 2- or 4(6)-lobed, connate with the leaves on both sides, often broadly so; androecia on a leading stem or short lateral branch; antheridial stalks biseriate; gynoecia terminating the main shoot or a long leafy branch; perianths trigonous, with the mouth 3-lobed and the keels sometimes winged; inner capsule wall thickenings forming fenestrae.

Note:—This genus is based upon the expanded concept of Chiloscyphus subgen. Connati as treated by Engel

(2010). Although we are changing the status of the Engel subgenus to the rank of genus, the name Connatae is

a Latin technical term in use in morphology and cannot be used as a genus name following ICN Art. 20.2

( McNeill et al. 2012). In contrast to Chiloscyphus s. str., which is characterized by undivided to retuse leaves,

gynoecia borne on short, leafless lateral branches, and short inflated perianths with emergent fleshy calyptrae,

Cryptolophocolea possesses bifid leaves, gynoecia that terminate leading shoots and elongate, trigonous

perianths, often with winged keels. In these features it resembles Lophocolea . It is morphologically distinct

from Lophocolea , however, in having large underleaves that are connate with the leaves on both sides, and in

developing fenestrate, rather than unbranched, thickenings on the inner capsule wall. We have chosen a new

name for the genus that reflects its morphological similarity to Lophocolea , while recognizing its "hidden"

status as a distinct monophyletic lineage.
