Armillaria sinapina

The brownish cap is {{Convert|2-8|cm|frac=4}} wide and the white, fibrous stem is up to {{Convert|10|cm|abbr=on|frac=4}} long. Both the flesh and spore print are whitish.{{Cite book |last=Audubon |title=Mushrooms of North America |publisher=Knopf |year=2023 |isbn=978-0-593-31998-7 |pages=447}} The mycelium is bioluminescent.

Armillaria gallica and A. calvescens grow only on dead wood (usually hardwood) but may require microscopy to distinguish. A. gemina and A. ostoyae are also simiilar.

A plant pathogenic fungus, it causes Armillaria root disease, and has been found on a variety of tree hosts in Alaska.
