Observation 140224: Inocybe (Fr.) Fr.
When: 2013-07-15

Notes: Inocybe species growing in grass directly under a Pin Oak (Quercus palustris). I did not get a spore print, so a measurment of mature spores was not done. However spores in a gill crush mount are very nodulouse and the largest ones approximately 8-10 microns long. Metuloid pleurocystidia were abundant and many heavily encrusted. Cystidia turn slightly yellow in 5% KOH.

You can get yourself the reactive easily?

Terrific references!

Can you provide a reference or details?

It is the technique which I ignore totally. Less spectacular, but so attractive, is the use of the reactive of Baillenger for the pleurocystides of Inocybes !

Thank you Claude!

The image of cystidia was taken using differential interference contrast (DIC) illumination and careful technique. I am very fortunate to own this equipment. I’m glad you like it!
