Russula sp ?

[kiltoncomp]

any one feel brave enough to id this one ?
found on the track bed of a disused railway bridge, on thin stony poor soil, no trees,
20 plus growing in a staggered group,
cap 3" dry , stipe 2" ,gills creamy white , brittle, spore print cream,
the drying cap is developing a red tinge to the edges,




any suggestions? or will this one remain Russula sp ?

Hello,

suggestion yes, determination no ....
I think you overlooked a small birch somewhere and this might be Russula pulchella (= exalbicans, = depallens).

There have to be some trees, as all Russula are ectomycorrhizal and therefor can only grow together with trees. 20 meters is no problem for the roots of big trees.

best regards,
Andreas

thanks Andreas,
the only "trees" on the actual bridge were some seedling birch, around 12" high, which i dont think would be the host, (or could they?), there were some small birch and hawthorns and possibly a small willow at the ends of the bridge, but again nothing large, (6/8ft), but given the shallow nature of the soil on the track bed, they could probably have spread more than is usual?

Hello Brian,

yes, those birch seedling are very likely to be the mycorrhizal partner.

best regards,

On separate occasions I have found Boletus luridus and Cortinarius anomalus growing apparently in the middle of un-treed calcareous grassland

on closer examination they were growing with Helianthemum nummularium (rock-rose) as their 'tree' - Dryas octopetala can, I believe, similarly stand in for trees

cheers

Hi Chris,
i had to stray across the wrong side of the border into South Yorks (Rother Valley) to find this one, strange things happen in Yorkshire
at least the Yorkshire fungi seem to disregard what is written in the textbooks about them
