Observation 114668: Polyporales sensu lato
When: 2012-10-22
Herbarium specimen reported

Notes: Not much of an odor, taste very bitter, fleshy.

An interesting chemical feature – turning entirely bright blue after 15 minutes in Congo Red!
Congo Red is a pH indicator, and turns blue below pH 3.0, suggesting that this polypore has some really acidic juices in it…

are all interchangeable to differing degrees. As far as I know, it depends on the species.

now synonymous with Oligoporus? These seem like Oligoporus to me.

What’s up with Postia? Is that the one Oligoporus guttulatus is now called? Confusing!

Tyromyces floriformis, but apparently that species has a tendency to grow in more imbricate clusters…
