When: 2015-08-04

Collection location: Gorham, Maine, USA [Click for map]

Who: Michael Kennedy (m005kennedy)

No specimen available

I found this on a trail in Gorham, Maine. This fungus was well attached and took some effort to pick. it had pores or compact tubes underneath it. It was very dense and hard. although it was in my air conditioned the mushroom had turned very dark brown. I cut it in half, and at that point it was very dark brown with no internal detail

not pores. The spines or teeth as they are sometimes called are very distinctive and would confirm this as Hydnellum given the other features that are apparent from your photos. Also, I was asking about the first photo. I can see it is bruising brown but I can’t tell from my pc monitor whether the lighter color on the cap is yellow or not. It looks yellow to me but sometimes it is hard to differentiate yellow from white or cream in a photo so I was asking you what it was in reality.

Inside of mushroom

I am afraid I waited too long to cut it open . the inside as pictured was a deep brown. The top had also started to turn brown. I wish I could give a good answer but I can’t. I am new to mushrooms and have just started to forage a few. I have found this page extremely helpful on identifying items I haven’t got a clue on. So, what I am trying to say is I am open to any correction. I compared internet photos Identified as Hydnellum P, and except for the reddish liquid it looked to be a good match. Please advice me if you have a better ID!

I assume this specimen had spines since you voted promising on Hydnellum sp.— I can’t tell from the photos and you mention pores/tubes in your description. Also, is the color of the fresh specimen yellow? It looks that way to me but I’m not sure whether it was yellow or whitish.


Extruded liquid

This had no extruded liquid . I assume , perhaps incorrectly , that it was to young yet to show that characteristic?
