Response Statements

Response Statement - Black-foam Lichen

In Canada, this lichen is at the northern edge of its range, and is known from Ontario, Quebec, New Brunswick and Nova Scotia. It appears to be extirpated from Ontario and Quebec and has not been seen in New Brunswick for about a decade. It occurs on sites dominated by mature deciduous trees with high humidity and moderate light. In Nova Scotia, this lichen is widespread but not common. The reasons for its decline are not clear. The main current threat is deforestation. Additional threats may include grazing by molluscs and climate change.
