Almost all pictures are from mushrooms or fungi in the more general sense with emphasis on the microscopic structures and copies of the descriptions. Descriptions and identifications in the album Herbarium Descriptions are mostly from my personal findings. Identification is done to the best of my knowledge at the moment of writing.

In the album Naturalis Descriptions you find observations from dried material temporarily obtained from the Netherlands Centre for Biodiversity Naturalis (previously the Rijksherbarium, Leiden).

In the more recent descriptions the micro photos of the spores cover an area of 66 x 44 μm. This to provide a magnification of x2000 in the printed version of the descriptions on a A4 sheet.

As collection photo's aren't always in a logical order when you browse through Flickr, use the collection number in the Flickr search field to group them together.

Use this search page for best results: www.flickr.com/search/?user_id=39538316%40N07&sort=da...

Use the search field also to group for example spores of Russula ochroleuca by entering the words: russula ochroleuca spores.

For those interested, pictures are made with the following equipment:

Chinese made microscope (1996) 160 mm tube length, DC controlled CREE XP-G3 R3 CRI 90+ LED illumination, fitted with Leitz 25x /0.75 Oil NPL Fluotar, Leitz 50x/1.0 Oil NPL Fluotar, Leitz 100x/1.32 Oil PL Fluotar. For the purpose of Differential Interference Contrast (DIC) a Zeiss Axiophot became available as of spring 2018. Zeiss Axiophot-1 microscope, fluorescence, DIC, DC controlled high CRI CREE XP-G3 R3 CRI 90+ LED illumination, Plan Neofluar objectives 10x/0.30, 20x/0.50, 40x/0.65, 40x/1.30 Oil, 100x/0.70-1.30 Oil.

12MP video camera with SONY Exmor IMX226 CMOS sensor with USB3.0 interface. Starting 2021 that camera was replaced by a camera that can capture the full field of view of 28.5 mm, the MTR3CMOS Series TE-Cooling 26MP Sony IMX571 APS-C sensor with 16 bit image depth from Chengdu Rising Technology Limited. Toupview advanced video & image processing application (integrated measurement, stacking, stitching, high dynamic range, etc).

Macro pictures in the field with Fujifilm X T5 with Zeiss Touit 50mm/f2.8 macro (till September 2023 with the Canon G12 with CHDK software and automatic focus bracketing program). Stacking with Helicon focus or Zerene Stacker.

Studio setup: Since November 2018 Macro pictures with a Canon 6D fitted on a Wemacro rail with one of the following lenses attached: EF100mm f/2.8L Macro IS USMII, Laowa 25 mm f/2.8 Ultra macro 2.5-5x, 4x/0.1 - 160 mm plan microscope objective with 260 mm extension tube. Both Canon 6D camera and Wemacro rail are fully computer controlled with Helicon remote and stacked with Helicon focus.

Many of the photomicrographs of Russulas were made possible by the continued help of many members of the Dutch and Flemish mycological societies.
