Description

It's a sad thing to see evidence of this disease...well, everywhere. Even at a thousands of acres preserve dedicated to science. This bay tree shows obvious signs of being a carrier, with the pathogen frying the tips of certain leaves. Good news, the only good news, is that drought seems to slow the spread somewhat as there is less water to spread the pathogen from plant to plant....

This park has lovely tan oak population; but some sort of blight is apparent. I understand that this is the Oak Death.

Something new this year. Seems to only have struck the fall-planted early/dwarf peas. Weird pods with separated layers, and then inside there are white fuzzes and no peas.

There was a question about if the spots we are seeing on this CA Bay Laurel are from Sudden Oak Death. Thoughts?

Description from Wikipedia

Oomycota or oomycetes (/ˌoʊəˈmaɪsiːt/) form a distinct phylogenetic lineage of fungus-like eukaryotic microorganisms. They are filamentous, microscopic, absorptive organisms that reproduce both sexually and asexually. Oomycetes occupy both saprophytic and pathogenic lifestyles – and include some of the most notorious pathogens of plants, causing devastating diseases such as late blight of potato and sudden oak death. They are also often referred to as water molds (or water moulds), although the water-preferring nature which led to that...
