Cinnoberbladet slørhat (Cortinarius semisanguineus)

Cinnoberbladet slørhat har det systematiske navn Cortinarius semisanguineus, men kan også klassificeres som Dermocybe semisanguinea. Hatten er en ret kedelig brun, men når man vender den om ser man de – overraskende kraftigt rødfarvede – lameller.

Cortinarius semisanguineus can also be classified as Dermocybe semisanguinea (according to this, it’s the same mushroom). Its name in English is surprise webcap or red-gilled webcap although most dyers seem to refer to it by its systematic name. Its gills have a strong red color, perhaps that is the “surprise” part to see the strong red color after turning over a rather dull brown mushroom.

Farve (Color)

Svampen indeholder (ifølge Lundmark and Marklund) det røde farvestof dermocybin og gul-orange emodin. Begge hører til en gruppe af naturlige farvestoffer kaldet anthraquinoner.

Nedenfor ses 3 farvninger med samme farvebad af hele svampe, første bad nederst. En vidunderligt støvet, varm rød farve.

According to Lundmark and Marklund, Cortinarius semisanguineus contains the red dye dermocybin and yellow-orange emodin. Both are found in a group of natural colorants called antraquinones.

The photo below shows first, second and third bath using whole mushrooms – a wonderful, dusty red.

Lystest (Light Testing)

Den røde farve fra cinnoberbladet slørhat er ganske høj. Her ses lystest af 1. bad udsat for ca. 500 timers lys. Den belyste del er til højre, og har næsten ikke forandret sig.

The red color from Cortinarius semisanguineus has good light-fastness. Here is a light test of yarn from the 1st bath, exposed to 500 hours of daylight (right side was exposed). The color change was very small.
