What You'll Learn
Environmental conditions (affect the intensity of orange)
Environmental conditions affect the intensity of orange in orange mushrooms. For instance, the orange shade of Marasmius vagus, a species of mushroom native to northern Australia and recently introduced to Florida, intensifies in dry weather and fades in wet weather. This species, also known as the wandering creamsicle, wandering parachute, or wandering Marasmius, is conspicuous due to its bright-orange caps and tendency to grow in clusters, arcs, and rings in suburban lawns. The caps of Marasmius vagus range in color from apricot to pale orange, with a diameter of 12 to 20 millimeters, and are initially dome-shaped before becoming flat with age.
Similarly, the orange Mycena, found in Missouri, exhibits a range of orange hues, from reddish-orange to yellowish-orange. This variation in color intensity may also be influenced by environmental factors, such as moisture levels or exposure to sunlight. The orange Mycena grows in dense clusters on deciduous wood, particularly during the months of June through September. Its caps are egg-shaped, evolving into a bell or conical shape with a sunken center, and measure between 1/2 and 2 inches in width.
In southern Europe, the Omphalotus olearius is a brilliant orange mushroom that typically grows in dense tufts from the decaying underground roots of olive trees. This species is poisonous and exhibits bioluminescence, with its gills emitting a ghostly green light in very dark environments. The intensity of its orange color may be influenced by the level of decay in the olive tree roots it inhabits, as well as other environmental factors.
Overall, while the specific mechanisms are not always fully understood, it is evident that environmental conditions play a significant role in the intensity of orange pigmentation in various mushroom species. These conditions may include factors such as humidity, sunlight exposure, temperature, and nutrient availability in the mushrooms' respective habitats.

Different shades of orange
Mushrooms come in a variety of colours, and orange is one of the most vibrant and eye-catching shades found in nature. While some orange mushrooms are beautiful and harmless, others can be toxic or even deadly. Here are some of the different shades of orange mushrooms found around the world, along with their unique characteristics:
Apricot to Pale Orange: Marasmius vagus (The Wandering Creamsicle)
Native to northern Australia, this small but conspicuous mushroom is one of the most common lawn mushrooms in Florida. It often grows in clusters, arcs, and rings, and its cap colour ranges from apricot to pale orange. The orange shade intensifies in dry weather and fades in wet weather. Marasmius vagus is not toxic to humans or animals and is considered harmless to the landscape.
Bright Orange: Jack-o'-Lantern Mushroom (Omphalotus olearius)
This poisonous mushroom usually grows in dense tufts from the decaying underground roots of olive trees. It is very similar in appearance to the Jack-o'-Lantern (Omphalotus illudens). The gills of this mushroom are bioluminescent and emit a ghostly green light in very dark environments. It is found in southern European countries such as Spain, Portugal, and France, and has also been reported occasionally in Britain.
Orange-Red and Orange-Pink: Cinnabar Chanterelle (Chantharellus cinnabarinus)
This edible mushroom is found in North America and produces various shades of orange-red and orange-pink. It is known for its apricot-like, nutty, and slightly floral flavour, with a peppery endnote. The cinnabar chanterelle is praised by many for its taste and can be prepared in various ways, such as sautéing with garlic, butter, and sage.
Redish-Orange to Yellowish-Orange: Orange Mycena
Found in Missouri, this small, sticky, bell-shaped mushroom grows in dense clusters on deciduous wood. Its cap is initially egg-shaped, becoming bell-shaped to conical, with a sunken centre. The cap colour ranges from reddish-orange to yellowish-orange, and the gills are pinkish-yellow with bright red-orange edges and a light cream inner area. While the gills appear orange, only the edges are truly orange, with the inner portion being light cream-coloured. This species is not edible.
These are just a few examples of the diverse shades of orange mushrooms found in nature, each with its unique characteristics, edibility, and distribution. Remember always to exercise caution when encountering wild mushrooms and to consult a mushroom expert or guide before consuming any unfamiliar species.

Bioluminescence
The light produced by bioluminescent mushrooms is regulated by a circadian clock, which is an internal biochemical clock that guides the cycles of activity in living things. The circadian clock allows the mushrooms to achieve peak luciferin and luciferase levels during the night, when the resulting glow is most visible. This suggests that the primary function of bioluminescence in mushrooms is to attract insects that can help them spread their spores and colonize new habitats.
One example of a bioluminescent mushroom is the jack-o'-lantern (Omphalotus illudens), which gets its name from its bright orange colour and nighttime glow. It is found in Europe and parts of South Africa and resembles the edible chanterelle, although it is poisonous. Another notable bioluminescent mushroom is the Flor de Coco (Neonothopanus gardneri), native to Brazil, which is one of the biggest and brightest of its kind.

Varying toxicity
The toxicity of orange mushrooms varies across different species. While some orange mushrooms are edible, others are toxic and can cause adverse health effects.
The Cinnabar Chanterelle, for instance, is an edible orange mushroom species found in North America. It is known for its apricot-like, nutty, and slightly floral flavor, with a peppery endnote. Another edible species is the Marasmius vagus, commonly known as the Wandering Creamsicle, which is native to northern Australia and has been introduced to Florida. This species is not toxic to humans or animals and is considered safe.
On the other hand, the Jack-o'-lantern mushroom is a large, bright orange mushroom that is not considered edible. Consuming this mushroom, whether raw or cooked, typically leads to vomiting, cramps, and diarrhea. Another toxic orange mushroom is the Omphalotus olearius, which usually grows in dense tufts from the decaying underground roots of olive trees, predominantly in Southern Europe. This mushroom is known for its bioluminescent gills, emitting a ghostly green light in very dark environments.
It is important to exercise caution when consuming any wild mushroom. If you are new to mushroom hunting, it is advisable to accompany a mushroom expert on foraging trips and to properly educate yourself on identifying poisonous mushrooms to avoid potential health risks.
