Background:

Natural dyes have been used since pre-Hispanic times. However, there is little literature on the extraction of fungal dyes to dye organic fibers.

Objective:

To evaluate the dyeing potential of five wild fungi on fibers of plant and animal origin.

Methods:

The fungi were fragmented, hydrated 24 h, and boiled for 45 min to obtain the dyes. Linen, henequen, scourer, hemp, and wool fibers were used to evaluate the effectiveness of the dye. The fibers were washed with neutral soap, mordanting, and boiled for 1 h in the dye. In a second experiment, the pH of the dyes was modified with vinegar, sodium carbonate and ammonia to test new colors on the fibers.

Results and conclusions:

The dyes showed dark reddish brown to light yellow brown hues on the fibers. The pH change produced beige, brown and light yellow, yellow and green, mustard yellow, light orange, reddish brown and light green hue with Chlorophyllum molybdites, Earliella scabrosa, Phellinus robustus and Ganoderma aff. lucidum recorded for the first time as dyes. Mushrooms are a good alternative for obtaining natural dyes.
