Agaricus santacatalinensis
species of fungus
Agaricus santacatalinensis is a species of agaric fungus. Described as new to science in 1998 by Edgardo Albertó, it is found in deciduous forests of Brazil, where it grows under privets (Ligustrum) and elm (Ulmus). The fruit bodies feature caps that are 7–12 cm (2.8–4.7 in) in diameter with felt-like surfaces. Somewhat unusually, the gills mature centrifugally (from the cap center outward to the edge). Initially, they are ochre yellow before turning dark brown after the spores mature. The stipe measures 8.5–12 cm (3.3–4.7 in) long by 1.5–2 cm (0.6–0.8 in) thick. It is white from the cap down to the ring, below which it becomes yellowish with orange tints. The base of the stipe has short yellowish rhizomorphs. The ring is membranous, measuring 1–2 mm thick. The edibility of the mushroom is unknown.
This brief starts where responsible research should: with the source description of “Agaricus santacatalinensis” as species of fungus. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of fungus. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Apr 19, 2024. The linked authority identifier is Q15637187. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1998.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
How to read it
