Tricholoma album - White Knight

Tricholoma album - White Knight

Taxonomy

Phylum: Basidiomycota

Class: Agaricomycetes

Order: Agaricales

Family: Tricholomataceae

Although not always a pure white knight (and never in shining armour), this is a very pale mushroom and therefore easy to find against the dark background of a forest floor… unless it has been snowing. (White Knights can appear as late as November and December.) This substantial mushroom can be found in both broadleaf and coniferous woodland. In Britain and Ireland it is rather a rare find, but in Scandinavia it is common in the spruce forests that dominate the landscape.
