I believe that observation 31839 is actually Porostereum crassum as noted on the card in the basket on the second image. http://mushroomobserver.org/image/show_image/73778?q=197vh&size=full_size. The name on the card is Phanerochaete crassa which was a previous name of Porostereum crassum.

her crust workshop with Tom Bruns at the Scott’s Valley NAMA back in 2012 was a highlight of my attendance at that event. Who knew crusts could be so much fun under the scope?! Waaaaaaaaaay cooler than in hand.

It made a crust fan outta me.

did Karen actually request this sample? Might be a good idea to run it by her first, if not.

Ok I shall.

I don’t own or have access to a microscope. I hope to get one in the near future. Then I will scope everything. In the meantime if anyone wants to scope any of my stock I will be happy to give a sample to you.

why not stick it under the scope…

Here’s a worldwide distribution map which of course is incomplete:

If you look at the map on this site: http://www.discoverlife.org/mp/20q?search=Porostereum you will see that Porostereum crassum seems to usally grow very close to the ocean. This map leads me to believe that it mainly grows in coastal climates like my own. This is completely hypothetical though. Another part of my hypothesis is the fact that it grows in Australia and Santa Cruz had imported eucalyptus trees that were brought here in the 1850s from Australia and they are all over the place here now. Possibly Porostereum crassum was inadvertently introduced into our environment via the eucalyptus trees.

It is…

It is oak. I have been checking up on the specimen from Pogonip I posted two months ago and there hasn’t been any change. That specimen is also growing on an old oak log.

What kind of tree is that?

I do not think this is Terana.

It is very fimbriate-byssoid whereas Terana is almost smooth.
