Beautiful smooth broad conical caps with broad umbos about 45mm wide. Most of these mushroom caps had dark greenish centres overlaid on a beautiful burnt orange base. Some had a thin line of membranous tissue around the margin and some margins were tinged blue. Gills were a pale brown colour and the stipe covered with white soft fibres. Some of the mushrooms showed a blue stain in the lower third. Spore print was brown.
Wood chip mulch
There were several other species of mushrooms growing in this mulch heap but these stood out - the blue-green stain was quite remarkable. The very mature mushrooms were almost black with flat caps. A similar looking species P. azurescens - found in the US http://www.accurateinformationmedia.com/...
