Observation 27917: Deconica merdaria (Fr.: Fr.) Noordel.

When: 2009-01-02

Collection location: Chico, California, USA [Click for map]

Who: canid

Specimen available

Notes:
This mushroom was identified to Psilocybe by spore print color, growth directly from equine dung, presence of a pellicle which is partially removable when young.

it was distinguished from P. coprophila/subcoprophila, P. merdicola and P. moelleri by it’s spore size [arond 10-14µm in length if my memory serves] and shape [hexagonal to subhexagonal in frontal view].

interesting observations:

mushrooms seemed only to fruit from areas which had been flooded by rain and drainage, often growing to maturity under 1 or more inches of water.

two specimens latently bruised blue.

i have several dried specimens preserved in my collection.
