Saprolittisia

Saprolittisia is a hypothetical genus used in taxonomic pedagogy and thought experiments to illustrate issues in genus delimitation, nomenclature, and the interpretation of molecular data in mycology and related fields. It is not recognized as a valid genus in major taxonomic databases and has no formal type species.

Taxonomic status: In discussions, saprolittisia is placed in an imagined family, Saprolittisiaceae, to explore how concepts such as monophyly, paraphyly, and polyphyly could influence genus circumscription. Because it is not described with a real specimen or sequence data, it remains a teaching construct rather than a published taxon.

Etymology: The name combines sapro- meaning decaying with a conventional genus suffix, mirroring patterns used in fungal nomenclature. The combination is intended to evoke a saprotrophic lifestyle associated with decomposing organic matter.

Conceptual characteristics: In hypothetical descriptions used for teaching, saprolittisia would be portrayed as a filamentous, saprotrophic organism associated with decaying wood in terrestrial ecosystems. Discussions typically address how researchers would approach circumscription using morphology, ecology, and molecular data (for example, ITS and LSU sequences), and how such data might support or refute the genus as a natural group. Because the taxon is not real, concrete diagnostic features are deliberately variable and depend on the teaching scenario.
