Which is a type of fern, Adiantum or Hylomecon?
Adiantum Adiantum , the walking fern or maidenhair fern, is a genus of about 250 species of ferns in the Vittarioideae subfamily of the family Pteridaceae, though some researchers place it in its own family, "Adiantaceae". The genus name comes from Greek, meaning "not wetting", referring to the fronds' ability to shed water without becoming wet.
Acantholichen Acantholichen is a fungal genus in the family Hygrophoraceae. A monotypic genus it contains a single species, the basidiolichen Acantholichen pannariodes, discovered originally in Costa Rica in 1998. This species has a bluish, gelatinous thallus, and a fine, white powdery bloom covering the hairy upper surface; this surface is said to resemble "an unshaven chin".
