Definition

Noun: 1. A taxonomic order of fungi: Aphyllophorales is an order of fungi within the class Agaricomycetes. These fungi are characterized by producing spores on basidia that are typically exposed on various types of fruiting body surfaces (not enclosed within gills). The order is polyphyletic and primarily includes saprophytic (decomposer) species, many of which have shelf-like or bracket-shaped fruiting bodies.

Usage

• The order Aphyllophorales historically grouped together many non-gilled fungi, such as polypores and crust fungi, based on morphological characteristics.
• Modern molecular studies have shown that Aphyllophorales is not a natural, monophyletic group, leading to the reclassification of many of its former members into other orders.

Examples

• "The decaying log was covered with fungi belonging to the old order Aphyllophorales."
• "Taxonomists have largely abandoned the use of Aphyllophorales in contemporary fungal classification."

Advanced Usage

• The term is now used primarily in a historical or taxonomic context to refer to a specific, now obsolete, grouping scheme. It is often seen in older mycological literature.

Variants and Related Words

• Aphyllophoralean (adjective): Of or relating to the order Aphyllophorales.
  • Example: "The study focused on aphyllophoralean morphology."

Synonyms

• Polyporales (in part): Many fungi once placed in Aphyllophorales are now classified within the order Polyporales.
• Corticioid fungi: A descriptive, non-taxonomic term for some crust-forming species that were included in Aphyllophorales.
• Shelf fungi / Bracket fungi: Common names for many of the conspicuous members historically placed in this order.

Notes on Meaning

• The core meaning refers to a specific, now outdated, taxonomic category in mycology. Its usage implies a classification system based on physical structure (like the lack of gills and the form of the hymenophore) rather than genetic lineage.

Noun

1. includes chiefly saprophytic fungi typically with shelflike bodies; sometimes placed in class Hymenomycetes or included in Agaricales
