I agree with your comment that this fungus appeared to be fruiting differently. The G. j-v does not disappear in a day…,

I added the only other photo I have. The fungus completely covered the young tree. I found it once more next to camp on an even younger incense-cedar. Though it disappeared by the next day.

I have heard of Gymnosporangium juniperi-virginianae, this fungus seems to be fruiting in a different manner. More so resembling the Guepiniopsis alpina that was everywhere. Though I wouldn’t know of any other options.

Any chance of another photo?
