The galls look the same but mine don't appear on any area but the crotch of the branches, and not all of the branches have the disease. Thanks for the tip though. I'm going to research apple bur knot some more to see if I can find out anything else.

hey ruby.. welcome to GW ... we like to teach .. so come back often ... i am relying on the prior ID ... you will probably get a lot of abuse as to the prior owner choice of plants ... if you use the GW search function.. you might find a couple hundred posts about how bad these trees are ... that said 2 things.. first.. its fall .. the leaves will be gone within a month or so.. IGNORE this COSMETIC problem ... as noted.. it comes and goes based on weather.. and ma natures whims.. it is NOT something you treat.. nor worry about ... especially on this aggressive weed .. second ... you already have a tree that is not structurally sound.. due to the fact that it is multi leaders low to the ground.. and it appear to be growing away from i am going to presume is shade.. its leaning to the right significantly .. which is going to make the above structural problems happen even faster.. perhaps a pic from a bit further back will give us a better idea of what is going on ... that said.. got anything else you need opinions on.. i am full of such today .. lol .. [though some may suggest i am full of something else.. lol] welcome ken

Looks like scale, all of it. Neem oil applied repeatedly will smother the scale. This little tree is very heavily invested, so this will take multiple applications. You don't mention if the tree is indoors or outdoors or where you live, so Coleen's advice is good - do not apply any hort oil if temps are above 85 degrees F. Patty S.

Until weather pattern changes, may not be much point in seeking remedy. Like Dax reports, so-called "anthracnose", not really a specific disease but rather, a constellation of similar-appearing leaf blights-will run rampant on susceptible species. Not sure what you've got there for a plant-a little more context in terms of stems, overall plant view, etc. might help, but in any case, not worth worrying about. These things come and go all over the place all the time, rarely amounting to much. Keep in mind, plants are well-adapted to withstand occasional foliar disturbances. It's the diseases that plug up xylem and/or phloem that really cause trouble. This ain't that. +oM
