Danny’s DNA Discoveries – Clavariadelphus of the PNW
Click here for my Pictorial Key to Clavariadelphus.
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:
The genetic picture of this genus is pretty unclear. The same sequence may have multiple species names attached to it, and for those species with more than one sequence available, the sequences are usually quite different. Here are the species reported from the PNW, but even though I have a couple dozen local sequences that you can download above, we'll need a study of this genus to give us type or other reliable sequences to compare to in order to figure out what they are. See my picture key for purported pictures of them, as best we can guess.
The only reliable genetic ID of a PNW Clavariadelphus we have is a sister species (5 bp and 2 indels) from the type sequence of Clavariadelphus aurantiacus from China, and that isn't even one of the species that is supposed to be here!
