Found this crested organ pipe while walking some washes Organ Pipe National Monument in AZ. Park service says they only know of about a dozen in the whole monument.

These large white and wrinkled spots have appeared on the new growth of my blue myrtle (Myrtillocactus geometrizans). Any idea what could be causing this and what I could do to stop it? Growing in southern AZ.

Thanks!
