Distribution and Habitat

  • Porella cordaeana is a Boreo-temperate European element.
  • It can be found in Canada, though its origin there is undetermined.
  • This species typically grows at the base of trees and on stones near water sources, such as lowland rivers and water meadows (e.g., valley of R. Tamar).
  • It has been observed in Sweden and Slovakia.
  • Sightings in Jylland, Danmark (Buderupholm Bjergskov, Rold Skov) have also been recorded.

Morphological Characteristics

  • Characterized by regularly pinnate branching with dense shoots.
  • Similar species have ventral leaf lobes that are long-decurrent.
  • Underleaves are usually not overlapping, rounded, and long-decurrent.
  • Perianth features are also characteristic for identification.

Genetic Information

  • Voucher specimen LISU: Sergio et al. 256258 contains trnT-trnL intergenic spacer and tRNA-Leu (trnL) gene, partial sequence chloroplast 367 bp linear DNA.

Chemical Composition and Interactions

  • Chemical constituents of Porella cordaeana extracts have been identified using solid-phase microextraction-gas chromatography mass spectrometry (GC/MS-SPME).
  • Two new natural products, &#945-furanopinguisanol and furanopinguisanone, have been identified.
  • Porella cordaeana belongs to pinguisane-type species of Porellaceae.
  • It contains immunomodulatory pinguisane-type sesquiterpenes.
  • Extracts have shown antimicrobial activity.

Quirky Facts

  • The species name, cordaeana, is derived not from the word "cord," but from the Costa Rican town of La Hondura.
