#57 Russula persanguinea

Notice the striations around the rim of the cap

A characteristic feature of identification of Russula species is the snapping like chalk of a fresh stem.  A pure white stem of Russula persanguinea will distinguish this species from Russula. aff. rosacea which has a pale pink stem.

Russula persanguinea is mychorrhizal with eucalypt roots and is found in wetter areas of eastern states of Australia, as well as Western Australia. It can be found fruiting at the base of live eucalypts, on the ground where there is buried wood, as well as around the base of dead eucalypt stumps. I am led to believe that it is the only species of Russula that fruits on dead wood, but I have not substantiated this.

Cap (up to about 70mm) is red, convex at first, broadening and flattening with maturity, usually with a shallow central depression where the colour is darker. The cap is viscid (or slippery) when wet, and striated around the rim at maturity. [There are no hints of purple or yellow]  Gills are white, crowded, and all of the same length.  Stem (up to about 70mm) is white, solid when young, and often thickening towards the base.  Spore print is white.

Toxicity: Some Russula species are known to be poisonous, so, although I have found no specific information on the toxicity of Russula persanguinea, it should be avoided.

The wet cap is slippery, the stem widens at base

The central depression in cap is a darker colour

White gills are crowded and all the same length

A wet, collapsed specimen is soggy all over, and pinkish

We recently found some of these a short walk from our Hunter Valley accommodation. I must admit we told the kids they were where the fairys lived and we shouldn't touch them!

Hi,

I like that, and they certainly look like they could shelter a fairy with their delicate and colourful caps :)

Cheers,

These ones are not edible, although not toxic either!
