About Fungi
Growing awareness of the importance of biodiversity and traditional Indigenous knowledge has renewed our fascination with fungi and lichens. While the world’s fungal diversity is vast, only a small percentage of fungal species has been catalogued. The five species presented in this stamp issue are all found in Canada:

A preferred winter food source for caribou, star-tipped reindeer lichen (Cladonia stellaris) grows in boreal and Arctic regions. Like all lichens, it is a fungus and an alga growing as one.

The oyster mushroom (Pleurotus ostreatus) is common to many cuisines. Researchers are experimenting with its tissues to make packaging, building materials and fungal leather.

The yellow-orange conks of chicken of the woods (Laetiporus sulphureus) were traditionally used to smooth and soften buckskin and to treat sore joints.

Used by Indigenous Peoples as a fire starter, tinder fungus (Fomes fomentarius) makes hard conks on deciduous trees. It can also repel insects when burned as a smudge.

Rhizophagus irregularis, a microscopic arbuscular mycorrhizal fungus (AMF), naturally integrates with plant roots and can also be added to soil to enhance crop health in farming.

About the design

Designed by Jocelyne Saulnier (Joce Creative) and illustrated by Emily S. Damstra, this stamp issue offers a close-up view of five species of fungi and explores their beauty in a style reminiscent of botanical illustrations.
