Definition

Noun: 1. A genus of fungi: A taxonomic category (genus) of fungi characterized by having the spore-bearing surface (hymenium) in the form of a crust. Some species within this genus were previously classified under the form genus Rhizoctinia.

Usage Notes
  • Scientific Classification: This term is used exclusively in scientific contexts, particularly in mycology (the study of fungi) and taxonomy. It refers to a specific group within the fungal kingdom.
  • Taxonomic History: The note about species formerly placed in is important for understanding historical classifications and scientific literature. was often used for an asexual (anamorph) stage, while might refer to the sexual (teleomorph) stage.
Examples
  • Scientific Text:
    • The fungus affecting the bean crop was identified as a member of genus Pellicularia.
    • Several species of genus Pellicularia are known to cause web blight in various plants.
    • The study focused on the genetic differences between genus Pellicularia and other corticioid fungi.
Advanced Usage
  • Taxonomic Context: In detailed taxonomic discussions, the genus name is often italicized () and may be followed by the name of the scientist who described it and the year (author citation).
    • Example: The type species for the genus is Pellicularia filamentosa.
Variants and Related Words
  • Pellicularia (n): The standard, non-italicized form used in general text to refer to the genus. When used in a formal taxonomic sense, it is italicized: .
  • Rhizoctonia (n): A form genus historically used for the anamorphic (asexual) stages of some fungi now classified in and other genera. This term is still commonly used in plant pathology.
  • Corticioid fungi (n): A descriptive term for fungi that form crust-like fruiting bodies, which is the characteristic feature of .
Synonyms
  • Corticium (n): This is a closely related or sometimes synonymous genus in historical classifications. Modern taxonomy may separate or merge these groups based on new genetic data. (Note: This is a technical synonym within taxonomy, not a general language synonym.)

  • Hymenium (n): The spore-producing layer of a fungus.
  • Web blight (n): A plant disease symptom often caused by fungi in this group.
