They may be small in size, but mushrooms are big on nutritional benefits.

With virtually no sodium or fat, they’re cholesterol free, contain the B vitamins niacin and riboflavin, and are a good source of dietary fibre.

Tasty and versatile, they’re used raw or cooked in a number of ways.

More than 85% of Australian households purchase fresh mushrooms on a regular basis. According to the Australian Mushroom Growers’ Association, they are the second most valuable fresh vegetable crop grown in this country after potatoes.

Mushrooms can be grown at home without any special equipment, and you don’t need a garden as you can use a kit and cultivate them indoors.

To grow white button and Swiss brown mushrooms indoors, just add water and keep the kit in a dark, moist spot. The spore of the more exotic oyster and shiitake can be grown on a mushroom board, wood or straw.

Depending on the variety, you can be harvesting mushrooms in three to five weeks’ time.

Use the kit contents as fertiliser when finished.

Commercial mushroom growing in Australia dates back to 1933, when they were grown in railway tunnels, including the Circular Quay to St James line before it was completed.

The industry moved outdoors in the late 1930s and mushrooms were grown in raised beds in open fields, covered in straw and hessian bags.

The mushroom industry is the ultimate recycler. The nutrient-rich compost in which they’re grown is made from stable bedding, straw, poultry litter and other organic materials. The finished waste is sold as garden mulch and fertiliser.

In Australia, you can pick wild mushrooms, and many mushroom lovers make the pilgrimage to pine forests in autumn to harvest slippery jacks and saffron milk caps, the two edible varieties.

Never eat wild mushrooms unless you can identify them accurately, as fatal poisoning can occur.

Take heed of the saying, ‘If in doubt, go without’.
