Notes: Code: Bot_665/2012_DSC5546
Habitat: Under a Picea abies, in mixed alpine forest, dominant Picea abies, Fagus sylvatica, Abies alba; south oriented mountain slope, calcareous bedrock however apparently acid soil (Vaccinium myrtillus); relatively warm place, mostly in shade, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 2-4 deg C, elevation 1.420 m (4.650 feet), alpine phytogeographical region.
Substratum: soil rich in humus.
Place: Mt. Mangart region, northeast ridge of Mt.Planja, 1.553 m, East Julian Alps, Posočje, Slovenia EC
Comments: Name Cortinarius sebaceus Fr.1838 is legitimate according to MycoBank as well as in Slovenian check list 1998, however it is unknown in Species Fungorum. Several other names can be found in literature as synonyms: C. turmalis, C. claricolor, C. sericelus, etc. where C. turmalis seems to be most often used. However Breitenbach Ref.(8) states violet color of mycelium for C. turmalis, which was not the case of this observation. Also, data from literature on spore dimensions for C. turmalis often state bigger spores than observed. Therefore I am staying with C. sebaceus. The observation fits very well to Daehncke Ref.(2) and Ref. (7) (however here under the name C. turmalis).
Growing in groups of many species, more than 30 observed, some appearing directly among superficial roots of a large Picea abies. Pileus diameter up to 8 cm, fruit body up to 10 cm tall; SP ocher-orange, oac756, abundant.

Thank you very much for your interesting comment Irene. At the first encounter with this species I did experienced its pleasant smell but didn’t observe pinkish mycelium. After I read your comment I thought I overlooked it in the field. Last Friday we had our Bovec mushroom fair and from this reason I went to the place again and collected a few fruitbodies to be exhibited at the show. Interestingly, when we were preparing the show (two days after collecting the samples) I noticed that at least three fruitbodies actually showed fairly distinct pink tint in their mycelium. I was happy to get this confirmation of the determination. So I wanted to document this detail photographically, but there was no time to take pictures during preparation of the show. So, I went to the third time to the same place last Suturday with the aim to make pictures. There were still many fruitbodies there (two pictures added from this trip), from still young to severely aged examples, however I was unable to find a single one with even a trace of pink in its mycelium. Disappointing! I don’t understand what and when this pink appears. May be the fruit bodies have to be in a refrigerator a day or two before they develop this color. Unfortunately this idea came to my mind too late. I didn’t collect samples this time. The only solution would be to go there to the fourth time … Thanks again.
and the pictures..!
This resembles what we used to call sebaceus before someone made it a synonym to turmalis, which I don’t find satisfying. Both turmalis and sebaceus are described by Fries in “Epicrisis Systematis Mycologici”, and the latter is the one that was described from coniferous woods.
The name sebaceus can be found in IndexFungorum. They have no opinion about the name, but you can read the original description there:
What I have observed on sebaceus is a pleasant and sweetish smell, sometimes a pale pinkish mycelium (but not violet).
