When grounds are stored they tend to develop green or blue-green fungus that looks like mold. The green fungus called Trichoderma, is very beneficial to the soil. The blue-green fungus is moderately beneficial. At any rate, moldy coffee is good to use directly in the garden, on your houseplants, or in the compost pile.
Sarah says coffee grounds can still be used in the garden, and can offer benefits if used correctly. "They increase the capacity of the soil to hold water," she explains. "Anecdotally people also use it as a weed suppressor". Sarah says the key is composting them first.
In most cases, the grounds are too acidic to be used directly on soil, even for acid-loving plants like blueberries, azaleas and hollies. Coffee grounds inhibit the growth of some plants, including geranium, asparagus fern, Chinese mustard and Italian ryegrass.
It usually takes between 48 and 72 hours to develop fully, but conditions may vary. Mold might also grow if the dry coffee is exposed to moisture. Storing coffee beans/grounds in an airtight, waterproof container is coffee storage 101.

Aspergillus mold is white and gray and appears fluffy or feathery and I've seen that mentioned in conjunction with the breakdown of moist coffee grounds. Rhizopus is the common bread mold. Although some people could make an educated guess, molds can only be positively identified with a microscope.
The substance you are seeing is the coffee chaff, which is a natural by-product after roasting.
sitophila is commonly known as the orange bread mold frequently found on foodstuffs, vegetation, and cork and can grow in a hot and humid environment such as in coffee dispensers.
Excessive acidic soil can kill or hamper the growth of plants like asparagus fern, Chinese mustard, Italian ryegrass, lavender, orchids, rosemary, tomatoes, and geranium. The roots of these plants are also not potent to absorb the nutrients added by the coffee grounds in the soil.
Since coffee grounds have such a pungent and intense smell, mosquitoes do not like to come near it. Mosquitoes are repulsed by all types of coffee, whether it is fresh, used, or burnt. The most effective way to use coffee grounds for mosquito control is by burning them, as it creates a stronger aroma.

The appearance of coffee scum is simply the natural coffee oils from the fresh coffee beans rising to the top of the cup. What is this? These oils are a combination of caffeine and other chemical compounds, including antioxidants, and contain roughly 71 percent unsaturated fat.

Make no mistake, white mold has its health risks, but it's just as dangerous as any other color of mold. Continued exposure to any kind of mold can pose a serious threat to your health with symptoms including headaches, nausea, dizziness, allergies, and respiratory infections.
However, the color black isn't unique to Stachybotrys — people often confuse it with similar-colored molds like Cladosporium, Aspergillus, Alternaria, and Dreeschslera. In earlier stages, black mold may appear more greenish-grey or greenish-black in color with fuzzy white edges.
