Eye3
Recognized by sight: Look at the first image. This specimen had branches as described in Hericium americanum and spines that were 4cm long also fitting it’s description, but H. americanum is said to only be found in eastern America.
This may be the first identified on the west coast.

coralloides was on American Beech, americanum was on Red Oak.

But, probably 95% of the time I find H. americanum it’s on beech, while H. coralloides is on a host of different hardwoods.

Great Photo!

The trees look different, do you know what kinds?

Hericium americanum on the right, H. coralloides on the left.

I would be inclined to call this observation Hericium erinaceus

The differents is structure.

There is actually no way to tell one from another not even microscopically. They only differ in structure. The image on the website your are referring to does not show branches only a semi dried specimen of what is probably H. erinaceus.

we see them do things we don’t often see in the wild, not necessarily because they are cultivated but because we get to see so many more. There’s an interesting photo here:

http://www.mushroomexpert.com/hericium_erinaceus.html

It shows a typical erinaceus, and one that looks branched like americanum. They were identified by a “prominent mycologist” as “erinaceus” but someone who returned later found only “americanum.” Were they really two species sharing the same log?

I understand

but that image is of one node separated from the hole specimen. Under that image is the same node after drying and the branch is attached. H. erinaceus does not form narrow branches like that.

Looks exactly like cultivated erinaceus. When they grow on smaller substrates they look like that, sometimes with more than one node. The beautiful erinaceus photos from your other observation are on a large tree?

Hericium americanum?

This specimen fits the description of H. americanum in all ways but location. Do you think it could have made its way to the west coast, or is that to far fetched of a proposal.

Here is the link to a Key to the 4 Species of Hericium in North America.

The measurements are in line with the description of this species.

Spines

The spines are 4 to 4.5 cm long max.

Looks good to me. How long were the spines?
