Bird’s Nest Mushroom

Erik Brians found a fungal-type growth under some garden plants in Sonora. He brought a sample back.

I removed one of the tubes, and cut it open, as you can see in a series of images below. It was tough and fibrous.

I passed the photos along to Dr. David William Fischer, Mycologist, at American Mushrooms®. He believes it is a type of bird’s nest mushroom, but long dead. You can see photos of living specimens here. Thanks Dr. Fischer!

Probable Canker Rot Fungi in Valley Oak

This valley oak, in the Chinese Camp area, is showing signs of a possible canker rot infection. The bark is bursting in numerous locations on the main bole. Overall, the tree looks healthy, with new leaf growth, and fullness in foliage. The tree has extensive sapsucker holes. A small swimming pool was constructed nearby.

2 August 2018.  Thanks to Dr. Ted Swiecki of phytosphere.com for help with the ID.

Dr. Swiecki states “In canker rots, the decay column extends out to the cambium in some places, causing a localized canker that can callus over, especially if the tree is otherwise vigorous.  ”
