There are lots of wild magnolias in the mountains of West Virginia. The cones are hot pink and closed when they fall in early summer, but they shrivel and turn black later in the season, cracking open to expose the orange seeds. Once they turn black, almost every cone encountered will support a colony of Strobilurus conigenoides.
Ornamental magnolias are also popular here, but I think they are a different kind. At least the one in my parents’ yard is a different kind, and I do not recall seeing mushrooms on the cones. According to wikipedia, there are over two hundred species of Magnolia. Many of the ornamentals are from Asia. I wounder if Strobilurus conigenoides is associated with the Asian species.
I suspect many of the west cost ornamental Magnolias are native to Asia.
You know were have plenty of Magnolia out here, but as decorative tree in landscaping, not in the forests. And I see these cones out here, sometimes fairly old and black, but I haven’t see a Strobilurus on them yet. I wonder what rots them out here, or why this species of Strobilurus hasn’t found them yet. Other things like pine and fir cones seem to each have their species of fungus that rots them, but out here not the Magnolia cones…
