pellicularia
Definition
- Noun:
- A genus of fungi: "Pellicularia" is a scientific name for a genus of fungi. The key characteristic of fungi in this genus is that their spore-bearing surface (the hymenium) is in the form of a crust. Some species now classified under Pellicularia were previously placed in the form genus Rhizoctinia.
Usage Notes
- Scientific Context: The word "Pellicularia" is used almost exclusively in scientific contexts, particularly in mycology (the study of fungi), botany, and plant pathology. It is a taxonomic genus name.
- Capitalization: As a proper noun denoting a genus, it is always capitalized: .
- Singular/Plural: When referring to the genus as a single taxonomic group, it is treated as singular. When referring to multiple species within the genus, it is often used attributively (e.g., species).
Examples of Usage
- Noun:
- The fungus was identified as belonging to the genus Pellicularia. (The scientific classification of the fungus was determined.)
- Some Pellicularia species are known to cause plant diseases. (Certain types within this fungus genus can harm plants.)
- The study compared the morphology of Pellicularia with other corticioid fungi. (The research examined the physical form of this genus.)
Advanced Usage
- Taxonomic Discussion: The name "Pellicularia" is used in discussions of fungal taxonomy and nomenclature, especially regarding the reclassification of species from older form genera like .
- The transfer of several species to Pellicularia clarified their phylogenetic relationships.
- Phytopathological Context: Used when discussing the causal agents of certain plant diseases.
- The damping-off in seedlings was attributed to a Pellicularia pathogen.
Variants and Related Words
- Pellicularia filamentosa: A notable species within the genus, formerly known as , which is a significant plant pathogen.
- Rhizoctonia (n): A form genus name historically used for anamorphic (asexual) stages of fungi, some of which are now classified under and other genera. This is a related but distinct taxonomic concept.
- Corticioid fungi (n): A descriptive term for fungi that have a crust-like (corticioid) hymenium, which includes the genus .
Synonyms
- There are no direct common-language synonyms for this scientific genus name. In highly specific taxonomic contexts, former names for included species (e.g., some forms) could be considered historical synonyms.
Related Terms (No standard phrasal verbs or idioms apply)
- Genus (n): The taxonomic rank above species, to which belongs.
- Hymenium (n): The spore-producing layer of a fungus.
- Form genus (n): A classification for fungi based on asexual (anamorphic) characteristics, not reflecting full phylogenetic relationships.
Noun
-
genus of fungi having the hymenium in the form of a crust; some species formerly placed in form genus Rhizoctinia
