New and Featured Content

Started 2021 with research and new pages

2021 January 5 to 8: Next update in this set is a big taxonomic mess and has propagated changes to my other pages for the family. Here are Aleurodiscus and the Stereaceae.

2021 January 3 to 5: Another simple update became a more complex several day process. Here is Xylobolus.

2021 January 1 to 3: What started as a simple update on Hymenochaetopsis turned into two full days of research on the mysterious glue crusts - Hydnoporia!

Ended 2020 with Major Guide Upgrades

Brief report summary for 2020.

2020 December 30: Moving Day! The CMS Kirby 3 version is now live on my website (testing finished 2:35 PM). See: Guide.

2020 December 28 to 29: Updating my Guide code to move from CMS Kirby 2 to current Kirby 3.

2020 December 25 to 28: Updating my Guide code to move from older CMS Kirby 1 to Kirby 2.

December 24, 2020: As this site continues with upgrades, please let me know if any images fail to load or other problems. The conversion to HTTPS should be complete.

December 23, 2020: Refactored the PHP templates for the new taxon page. This is the new live Stereum page. These new PHP templates can be developed further without breaking the previous set of templates.

December 17 to 22, 2020: Refactored (rebuilt) the new taxon page layout that I developed during November to December. About every two years I improve the page code for current best practices of HTML5 and CSS3. For 2021, this work includes finishing the transition (for all 200+ pages) to CSS3 Grid and Flexbox for layout rather than floats; improving the semantic structure; refactoring the PHP templates.

Mushroom Description Pages

Building pages for the many different kinds of macro-fungi in the Chicago area. These are a few examples of species pages. There are also higher level pages from Kingdom down to genus. For example: Cantharellus, Hypocrea, Stereum, and Trametes. For all of the fungi pages see the Guide Site Map.

Highlights from other websites

Read the article by Nance Klehm in the Chicago Reader: Fungus among us – Cramp balls, puffballs, and more friends in the woods. Nance interviewed me, during a walk in the woods, about my work, mushrooms, and the IMA.
