Pterula penicillata taxonomy
The taxonomic history of this species is a little complicated and unclear.

It was first described in 1790 by the French mycologist Pierre Bulliard who classified it as Clavaria penicillata.

In 1826 the French mycologist François Fulgis Chevallier reclassified this as Penicillaria multifida however this is now a nomen superfluum and considered illegitimate. Penicillaria is now used for a genus of moths and is also the name of the order in which Arachnactidae anemones are placed.

In 1829 the Swedish mycologist Elias Magnus Fries reclassified Bulliard's Clavaria penicillata as Anthina (Pterula?) penicillata and this was formally reclassified as Pterula penicillata in 1930 by Fries.

However Clavaria penicillata may still be an accepted species name in some sources and Pterula penicillata may not be accepted.

''Pterula multifida var. densissima'' was described in 1958 by the Czech mycologist Albert Pilát.

Notes to self
also Lepiota zeylanica synonym for L. zeylanicus?

Leucocoprinus otsuensis Hongo, ''J. Jap. Bot.'' 28: 70 (1953)

In 1953 the Japanese mycologist Tsuguo Hongo documented a species from Ōtsu, Japan which he classified as Leucocoprinus otsuensis having previously classified it as Lepiota otsuensis. Hongo noted that the species was very similar to L. brebissonii but that it could be distinguished from it by the squamules (scales) on the cap. However this is now considered a synonym of Leucocoprinus brebissonii.

Find where it got reclassified and how the Lepiota mentioned in the 1953 paper is in a 1959 one, wrong citation or existing species?

우산각시버섯 - Korean name for it meaning Umbrella mushroom. Seems common there.

Mushrooms containing gastrointestinal irritants are one of the most common sources of mushroom poisonings however of thousands of documented cases only one fatality was reported in the US.

The texture of the stem ring may be smooth and thick, membranous and flexible or it can present with scales or a woolly surface with a variety of terms such as squamulose furfuraceous tomentose etc

== Species == , Index Fungorum accepted 84 species of Leucocoprinus  and the GBIF recorded the following number of observations for Leucocoprinus species.

The number of observations recorded does not necessarily correlate directly to how common the species is as this figure is also influenced by how commonly known the species is and hence how often it is reported or suggested as an ID on citizen science sites. GBIF includes observations from iNaturalist in its dataset with the only criteria for inclusion being that the observation is tagged as 'research grade' and is confirmed by a second user. This however does not mean the identification is necessarily correct and misidentified species will be contained within this data. For this reason the GBIF observations are also presented here with the iNaturalist dataset removed. The total number of observations for each species also includes those for former classifications which are now considered synonyms of the currently accepted species.
