Mycena semivestipes
species of fungus
Mycena semivestipes is a species of agaric fungus in the family Mycenaceae. It is found in eastern North America.
Taxonomy
First described in 1895 as Omphalina semivestipes by Charles Horton Peck, the species was transferred to Mycena in 1947 by Alexander H. Smith. The type collection was made in Newfoundland, Canada.
Description
The cap is initially convex to somewhat conical before flattening out in age; it attains a diameter of 0.8–3.5 cm (0.3–1.4 in) wide. The cap surface, smooth and slightly lubricous, is deep viscous to dark brown in the center. The margin is somewhat translucent, so that the grooves made by the gills are discernible. The thin flesh has a firm texture similar to cartilage, a distinct strong nitrous odor, and a mild to somewhat bitter taste. The gills have an adnate attachment, but often recede from the stipe as the mushroom matures. Their color is white to dirty pink.
Begin with the source’s own compact description: “Mycena semivestipes” is species of fungus. The dossier treats that line as a proposition to test through Mycena, semivestipes and species, not as a finished interpretation.
Why this record matters
The phrase “species of fungus” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jan 10, 2024. The linked authority identifier is Q6946905. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1895 and 1947.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
