Observation 56949: Inocybe curvipes P. Karst.
When: 2010-10-17
Herbarium specimen reported

Notes: Growing in a mixed pine/oak woods.

Cheilocystidia is not very abundant, but not rare either. On the gill edge there are some thin hyphae that are similar to very thin cystidia.

New trick for photographing cystidia

I tried something new while taking these pictures. On the higher maginifications the depth of field is extremely narrow, so it is only possible to take a clear picture of a microstructure if it is lying completely flat. I took two pictures, one focused slightly different than the other, giving me two photos with the camera in exactly the same spot, one with the base of the cystidia in focus and the other with the tip. I used the gimp photo editor to copy the part of the cystidia that is in focus and paste it on to the other photo, so the whole thing is in focus. Took about 5 minutes to get it right, but the result looks good. Two of the pleurocystidia photos were enhanced in this mannor.

I edit nearly all my micrographs using The Gimp. Usually I crop the image and correct the colors, adding contrast to make the cystidia stand out. Sometimes I use the unsharp mask to sharpen the image.

Cool microscopy
