Name that giant, alien-like fungus!

A few weeks ago the mystery in the neighborhood was a bunch of jumping oak gall…which we didn’t know at the time were millions of tiny galls each with a wasp larva inside doing the mambo.

Now it is a giant, alien-like fungus in my back yard. We bought our house 6 years ago when we moved to Davis. The people living here before us had planted an orchard of various fruit trees on the west side of the house. I know from experience in the Seattle area that orchards are rich grounds for unusual mushrooms (members of the fungus family) including morels. mystery mushroom

In our inherited mini-orchard in Davis something fungus-like, but more monstrous grows (see image above).

Just shy of the size of a baseball, these dark brown, hard-shelled (very odd) mushroom like things sprout up this time of year or later into fall .

I’ve seen a lot of mushrooms in my life hiking in the mountains in Washington, Oregon, and California, but I’ve never seen anything like this.

I think it is a mushroom, but what the heck kind is it?

In the name of science, I broke the apparent cap off of the stem and low and behold it looked more mushroom-like with “gills” and smelled powerfully like a mushroom (See below).

However, the inside was filled with liquid!

This putative mushroom weighed approximately 100 grams!!! Crazy.

Anyone know what kind it is?

  1. I too believe I have found the same mushroom in Gaston County, NC, yesterday. I found three of them in a small area on the side of a road. I wish I could share the picture with you. I kicked one over and it was very dense. I have never seen such a dark chocolate colored mushroom.


  2. I have been searching the internet for about half an hour looking for information on this mushroom(?) I have had 2 or 3 grow in my yard. The last is a doozy – about 8 inches high and must weigh a pound. What are they?
