Many people think of mold as either green or black, which is common, but mold can appear in a rainbow of colors. Whether in the garden or inside the house, mold may grow in shades of red, white, yellow, blue, purple and orange. Orange mold may be difficult to spot in the garden, particularly in colorful flower beds. Identify the orange mold to determine what is causing the problem and to find the best way to treat it.
Orange Slime Mold
Observe the color of the mold. One particular type of slime mold is usually very bright orange in color, though it may change to a more reddish or pinkish hue over time.
Test the consistency of the mold by poking it with a stick. Orange slime mold, which grows on decayed woody materials, is very moist at first, and dries into a hard crust that will be difficult to poke through.
Look inside the mold. Cut into orange mold using a garden trowel or another sharp object. The inside of orange slime mold is black.
Observe the texture. Orange slime mold is lumpy in appearance, and is often compared to vomit.
Wait for the mold to harden and dry completely before you remove it from the garden. To remove dried orange slime mold, put on gloves to protect your hands, then pick it up and discard it. Orange slime mold is not harmful to you or to your garden, but it is unattractive.
Orange Peel Fungus
Observe the shape of the fungus. Orange peel fungus grows cup-shaped projections that look like bowls.
Look at the color markings of the fungus. Orange peel fungus may be pale or very deeply colored, with reddish tint mixed into the orange.
Check the edges of the fungus. Orange peel fungus is prone to splitting and rarely maintains its symmetrical, bowl-like shape.
Compare the inside and outside surfaces of the fungus. Orange peel fungus has a glossy sheen inside the bowl, while the outside has a duller look.
Remove orange peel fungus by hand, digging it directly out of the garden. Orange peel fungus is edible, but it is not highly prized as a culinary offering.
