Danny’s DNA Discoveries – Gomphaceae of the PNW
Click here for my Pictorial Key to the Gomphaceae.
Clavariadelphus are placed in their own family, Clavariadelphaceae. They are tough club-shaped mushrooms usually with a fertile wrinkled stem. Like most other Basidiomycota clubs, they do not have a truly differentiated head and they are not covered in pimples. However, the head can sometimes be expanded and/or flattened enough to make someone mistake one for a chanterelle or Turbinellus false chanterelle (with a scaly, indented cap).
abundant common uncommon rare - colour codes match my Pictorial Key and are my opinions and probably reflect my bias of living in W WA. Rare species may be locally common in certain places at certain times.
Summary of Interesting Results
Here are some of the newest, most interesting results of the study:
Gautieria, Protogautieria and
These are the false truffles from this family. Gautieria have thin skin that wears away allowing you to see into some of the hollow chambers inside. The texture is enough like rubber that some fresh specimens might even bounce. Some are odorless but some smell somewhat nauseating. More details about these will come later.
Crusts from this family. More details later.
Gomphus and Turbinellus
False chanterelles with a veined stem (a busier pattern than the parallel ridges of true chanterelles).
Gomphus aff clavatus EU - has a purple stem with a more drab, smooth cap. Our species is about 3% different in ITS from EU sequences, so it might need a new name. Cantharelluis brevipes is an east coast species thought to be synonymous, but we need east coast sequences to see if ours is the same as theirs and can share a new name. Gomphus clavipes is available as a name, if so.

Turbinellus cf floccosus PN - orange, with a indented cap with flattened scales. The orange may fade to brown. We have many local sequences, but no east coast sequences to show that we have the real species here. India and Myanmar and even Arizona seem to have sister species so I'd like to rule out that we have a sister species too.
'Gomphus' bonarii CA - this similar southern species is smaller, clustered, paler, with more erect scales and often partially buried. It is considered by some a synonym. If not, it needs to be transferred to Turbinellus. We need sequences to find out. One Whistler collection seemed to fit the description and had the same sequence as T. floccosus, but we need California collections to find out more reliably.
Turbinellus kauffmanii WA - this local species has dull brown colours even when fresh and thicker, more erect scales.
