Brief Description: [See More | Edit]

Psathyrella is a large genus of about 400 fungi, and is similar to the genera Coprinellus, Coprinopsis, Coprinus and Panaeolus, usually with a thin cap and white or yellowish white hollow stem. But the caps do not self digest as do those of Coprinellus and Coprinopsis. Some also have brown spores rather than black.

These fungi are often drab-colored, difficult to identify, and inedible, and so they are sometimes considered uninteresting. However they are quite common and can occur at times when there are few other mushrooms to be seen. The first report of a gilled mushroom fruiting underwater is Psathyrella aquatica.

….the very best worldwide monograph – with descriptions – of the genus Psathyrella, in English and in high quality PDF format? This genus needs A LOT of work on MO and elsewhere.

I am glad that you agree with me!

The MO Name Pages are bizarre and they have nothing to do with MO Observations, which are the core of MO. I would deprecate them all. MO would be much better, more professional without them. Adolf

Deprecating “Psathyrella” was an accident…

Theory of Homoeostatic Resilience

Just this morning I developed the term “Homoeostic Resilience”. according that theory, every more sophisticated system deteriorates to the least common denominator of its users. This is well documented by this page. AC
