Observation 67012: Cortinarius austroviolaceus Gasparini

When: 2011-05-05

Collection location: Brimbin Nature Reserve, Taree, New South Wales, Australia [Click for map]

Who: Ian Dodd (kk) (www.kundabungkid.com) Australia (kundabungkid)

No specimen available

These mauve capped fungi were about 4cm in height. The caps were dry and the stems had banding running at about 45degrees across the stems. The caps were darker in the centre becoming less colour saturated towards the perimeter. The Gills were close and more saturated in the mauve colour. The stem appeared to mark easily and show a darker colour when the area was exposed. The substrate was soft and had good mixed levels of varying debris. The was no unusual identifiable aroma.
I was unable to Create the naming used by Bruce : Cortinarius sp. aff. violaceus.
However the database did except the shortened name? Not sure if this was technically correct, but I am sure some-one more knowledgable than I will assist. Added note********* Brimbin is a natural Eucalyptus forest Reserve. Semi dry aspect with a local fresh water creek in one area and on the eastern side of the reserve is a tidal brackish salt water creek. This creek is about 25 klms from Taree, NSW, coastline.

Northernmost collection???

C. austroviolaceus has only been collected in Victoria and Tasmania. Could this be a closely related species? Or the northernmost collection of C. austroviolaceus???

light violet?

The description says “blue-violaceus in every part” and my photos look darker, but the rest of the general habit fit.

thanks Emma.

that is exactly the kind of info I was looking for.

Keep on finding these cool fungi, Ian! I sure can’t hold a candle to YOUR finds, these days.

Find Area.

The location of the find is a Eucalyptus forest reserve, with both fresh water stream, and brackish (salt) water tidal creek within its boundaries, and about 25 kilometres West of Taree NSW, and the Eastern Coastline.

C. violaceus vs. C. austroviolaceus

C. violaceus and C. austroviolaceus are not related. They have the same purple color. C. violaceus turns red in KOH while C. austroviolaceus is reported to turn pink in KOH. However, C. violaceus has both cheilo- and pleurocystidia while C. austroviolaceus only have cheilocystidia. The granulation on their spores is different too.

just looked it up on IF …

yep, it’s a published name.

is austroviolaceus a published name, Emma?

otherwise, shouldn’t it be in quotes?

There seem to be macro-morph differences between Ian’s lovely find and our shaggy capped, purple NA violaceus, too. Are they fairly closely related?


TimmiT, What you say is exactly right. I tried the Australian naming and the site would not accept it. Used the shortened version and it was accepted! Where do we go from here with Southern Hemisphere naming if we do it in error. MMMmmm

Molecular studies have shown that the Australian material is genetically distinct from Northern hemisphere collections of C. violaceus (and so represent a distinct species). In a technical sense the Northern hemisphere name of Cortinarius violaceus is probably not appropriate for this collection.

The name Cortinarius sp. aff. violaceus gets the message across well but isn’t supported by the site. To my knowledge the Australian version has not been formally described, so I suppose the best name for this observation is Cortinarius sp.


Thanks for that info, (Timmit) Do you agree with the naming please. It looks right to me, I think? damon brunette (damonbrunette) is usually on the ball.

sp. aff.

sp. aff. is an abbreviation of species affinis. From latin ‘affinis’ translates as ‘akin to’ or ‘related to’. It means that the specimen closely resembles the named taxon but represents a distinct species (either unknown or undescribed).

So “Cortinarius sp. aff. violaceus” means it’s a Cortinarius species close to C. violaceus (but not C. violaceus)
