Danny’s DNA Discoveries – Hydnaceae of the PNW
by Danny Miller

Click here for my Pictorial Key to Chanterelles and Hedgehogs.


Did you ever think you found a chanterelle and then looked underneath it and saw teeth instead of veins and realized it was a hedgehog? But that it tasted as good and about the same anyway? Hedgehogs' closest relatives are chanterelles, so you really can think of them as chanterelles with spines. Hydnums were named before chanterelles, so the family name is named after the hedgehogs instead of the chanterelles.

There are many unrelated false chanterelles and false hedgehogs not covered here. Real chanterelles are smoothish capped orange and black species with a particular veined to wrinkled look under the cap that runs strongly decurrent down the stem. False chanterelles have true gills or a scaly cap with a different kind of veining. Real hedgehogs have spines under the cap, "clean" orange to white cap colours and a white spore print. False hedgehogs have more sordid colours.

A good overview of the Cantharellales can be found here.

Summary of Interesting Results

Here are some of the newest, most interesting results of the study:

  • I have sequences of two novel genetic PNW species of Hydnum not included in the recent study which will need to be collected, described and named.

Cantharellus - click to expand

Strongly decurrent veins/ridges under the cap that are more blunt than true gills. Orange coloured smooth cap. Solid stems, unlike Craterellus.

Craterellus - click to expand

Strongly decurrent veins or wrinkles (sometimes almost smooth). Orange or black colours. Hollow stems, unlike Cantharellus.

Hydnum and Sistotrema - click to expand

Spines under the cap. Clean pale orange colouration and white spores. A recent study clarified most of the species of Hydnum around the world and can be found here. Unfortunately, many can only be distinguished microscopically at best or by DNA at worst, and morphological and ecological differences have not always been found to back up the DNA differences yet. They are not going to be identifiable on sight.
