Springtime Inocybe/Havannah Three Hills

[John RKeymaster]

Habitat: soil in deciduous woodland; willow, hazel and birch

Cap: up to 6cm. Light/medium brown when wet to golden brown when dry. Slightly radially fibrilose, splitting when older. Sparse remnants of white cortina when young.

Stem: up to 6 cm x 0.8 cm with slightly clavate to bulbous base. Not pruinose.

Gills: cream to pale tan/olivaceous, adnexed. Gill edge white, rough. GEC cylindrical to flask-shaped, thin-walled, non-metuloid.

Spores ellipsoid to bean-shaped, smooth. Me = 10.2 x 5.3 µm ; Qe = 1.9
SP: light brown

Smell: indistinct

I get it as far as Rimosae using the Moser Agaric key (which is a quite old). Any suggestions appreciated.

John I think Inocybe maculata. It is one of the commonest in our area and although maybe slightly pale everything else fits nicely!

Thanks for the suggestion Doug. There are a few reasons I thought it might not be maculata (although it may well be).

The light cap colour and lack of fibrous white scales at the centre
No reddening on the stem nor white wooly stem apex
GEC are not club-shaped but cylindrical to flask-shaped

It keyed out in my very old key to I.fastigiata (and Dominique suggested I. rimosa which is the modern name). However it doesn’t really fit with rimosa either as

It has a slight bulb on some specimens
the cap is not as strongly radially fibrillose as expected
it is more a more golden yellow than reported

There is a suggestion that rimosa is a variable group, but then maybe maculata is too…?
