Pseudohydnum
Encyclopedia
Pseudohydnum is a genus
of fungi in the order
Auriculariales
. The genus, first described by mycologist Petter Adolf Karsten
in 1868, has not been classified
with certainty into a family
, and so is incertae sedis
with respect to familial placement. Pseudohydnum is monotypic
, containing only the widely distributed species Pseudohydnum gelatinosum.

Monotypic
In biology, a monotypic taxon is a taxonomic group with only one biological type. The term's usage differs slightly between botany and zoology. The term monotypic has a separate use in conservation biology, monotypic habitat, regarding species habitat conversion eliminating biodiversity and...
