Observation 134200: Cortinarius kioloensis Wood

Found two unusual fungi growing on the forest floor in close proximity. The caps were dark brown almost black and the stipes in good light showed a purple tinge. I almost overlooked the fungi as they were difficult to notice in the poor light. I did notice that the caps were quite soft and easily broken and that there semed to be a particular feature with the gills. They appeared to break away in layers as shown in the last image. The colour of the broken gills displays the tinge of purple colour that is not evident when viewed from the underside of the caps. Here the gill colour is dark brown. Note. 2nd last image shows cut stipe features. Specimen saved.

Summary Cortinarius Dried Specimen.

Thanks Emma. I will anxiously wait for any updates in the future.

Not Austroviolaceus

I had a look at the spores and cystidia today. The spores are (10.46)11.49(13.00) X (7.04) 7.96 (8.96) um, while C. austroviolaceus has spores <10um. The cheilocystidia are not capitate. They contain several wobbles that are not found in American material. Thus far, it fits C. violaceus sensu Bougher & Syme (1998), which was collected in Denmark, SE of Perth, under Eucalyptus. I’ll get a DNA sequence soon. This Bougher and Syme collection has been sequenced and is not the same as Northern Hemisphere C. violaceus, but it has not been described yet.


Downloaded the Paper and Thanks. Will send you a dried specimen as promised, for your studies. Give me a week or two, as I have specimens to sort and dry, and some to post away when ready. Chow, kk Good luck with your studies. I look forward to you loading to M.O. in the future.

Comment fr Emma H

Hi Ian,

This is indeed in the Cortinarius violaceus group. I am currently studying this group and would be interested in including this specimen in my phylogenetic study. C. violaceus does not occur in Australia. Gasparini described C. austroviolaceus from Tasmania, but Neale Bougher collected something from the C. violaceus group from Western Australia that does not fit with that description. It is probably another undescribed species. If you want to try and identify the specimen, it will need microscopy. This is the paper to look at:

Gasparini, B. (2001). A Contribution to the Knowledge of Cortinarius and Allied Genera of Southern Tasmania, Australia. Australasian Mycologist, 20(1), 49–54.

I can send you a copy if you like.
