This could be sap from the tree, or it could be something that the lichen produces. At any rate, the tree’s bark does not look healthy.
Close up of the ﬂat, hairy parts of the lichen on my cousin Clifton’s peach tree.
A veritable forest of lichen on my cousin Clifton’s peach tree. There are ﬂat, hairy, scalloped “leaves” and fern-like “trees” that seem like they should come from two different types of plants.
There’s a whole other ecosystem growing on this peach tree. At ﬁrst it just seems like a nice green tree, but take a few steps closer and you realize there’s something weird about it…
