~~ Not a British species ~~
Chlorophyllum molybdites (false parasol / green spored parasol / the vomiter)
Currently staying out in Tenerife, and I was rather delighted to stumble upon these late one evening. Anyone who knows my slight obsession with the various parasols will know how cool this is - I was expecting to have to go the the USA to see these.
This is a species sometimes mistakenly cited by people in the UK, probably down to American focused sources where it is native. In the UK - largely we can forget about its existence - as far as I know it has never been recorded outdoors in the UK, and only once indoors in Scotland in a hothouse in 1991 - it is a heat loving species. This is handy, since, given the common name, it is the Chlorophyllum known in the USA to cause a large spate of gastrointestinal poisonings (hence, the ‘vomiter’), unlike our 3 native Chlorophyllum (rhacodes, olivieri, brunneum) which are largely considered edible (with brunneum perhaps less so).
Just for fun, some features: one main feature is of course the green spores - I believe only molybdites of the Chlorophyllum and Macrolepiota has this, though it’s less evident on young specimens. It has a more straight and less bulbous base than our native Chlorophyllum, and also the cap ornamentation is more reminiscent of Macrolepiota (in my opinion). The underside of the non-easily-moveable annulus also seems to often be brown. The same plainer stipe like other Chlorophyllum.
