Title & Introduction
The forest disease I have chosen to report on is the Indian Paint Fungus. The scientific name is Echinodontium tinctorium. The nomenclature goes as follows:
Kingdom: Fungi
Division: Basidiomycota
Class: Agaricomycetes
Order: Russulales
Family: Echinodontiaceae
Genus: Echinodontium
Species: E. tinctorium The Indian Paint Fungus is a fungi or a mushroom as some call them. It is considered a pathogen that affects millions of board feet every year. It is Responsible for Red Rust Stringy Rot. This is a heartwood rot that severely weakens the structure of the tree as well as reduces the viable lumber that can be created from a tree. It gets its common name from Native Americans who would use the conchs of the fungus as a pigment. The inside of a living conch is rust red and would be ground to use as pigment or on skin to prevent chaffing.
General Information The Indian Paint fungus is part of a groups of Basidocarps that infect Fir and Hemlock trees decaying the heartwood. Basidiocarps use conchs to spread spores. The fungus prefers Fir and Hemlock trees in the Cascade, Coastal, Sierra Nevada and Rocky Mountain ranges. It is single most destructive pathogen in British Columbia, responsible for millions of dollars in lost and damaged lumber. It has been observed on some Spruce but that is rare and may be a sub species. The Fungus does provide a valuable service to the forest in tree population control as well as create habitats for many different forest birds and animals. Infected trees often fall prey to wind throw damage. The heartwood rot often leaves the tree hollow, so when wind throw damage does occur the resulting hollow cavities provide excellent habitat for birds and other small mammals. The conchs themselves hold no nutritional value to humans or wildlife.
Description
The Indian Paint Fungus is just that, a fungus. The main fruiting body is a conch. It
