Observation 129390: Stropharia (Fr.) Quél.
When: 2012-10-07

Notes: These mushrooms were found in mixed woods growing from the ground. The spore print was dark brown and the spores were elongated ellipsoids with a distinct germ pore. Spore print spores were measured and the 20 spore average was 12.5 × 6.8 µm with Qm = 1.8. Microscopically this was a very interesting specimen. Abundant lamellar cystidia had contents that turned bright orange in Melzer’s. The distinct central mass in these chrysocystidia made them easy to locate, even in BF illumination, despite only faint yellowing in 5% KOH mounts. There were also some larger and less abundant thin walled cystidia which had no staining contents. See photomicrographs, which show the above details clearly.
