Observation 294188: Lactarius Pers.

Notes:
I would be interested to know if anyone has any information on the strange growth pattern of the gill area. There were 3 fruiting bodies, two had this strange growth pattern but the third did not. The third was also in advanced stage of decay thanks to larval invasion.

I am far from experienced with Lactarius … have only found a few species in my area. However, a few characteristics of your specimens remind me of Lactarius sect. Deliciosi (formerly Lacterius deliciosus and L. deliciosus group), namely the gills which are generally forked at both the apex and the cap rim and often reforked, as in your thumbnail image. This species also exhibits orange staining of flesh (seen in one of your images) and green staining of the gills over time. I also think I can see some zonate coloration of the smaller/younger cap in one of your images. Interestingly Arora comments in his MD (as you did in your notes) that older specimens are frequently maggot ridden. There are many observations of this species on MO, a lot of which are from Oregon and the PNWobservation 151398 may be particularly helpful for comparison of the gills. I am not confident enough to propose this name, but hope it gives you a place to start researching the species for this observation..
