For both the list and the word for the relationship. I was even able to find the name of a non-photosynthetic plant I sometimes find (Pleuricospora fimbriolata) which I had been unable to find before. I thought it was rare, but apparently it is found throughout the west coast area.

Did you know Pinedrops are also one of the indicator species for matsutake being nearby?
