Hi and thanks for contacting Ask Extension. This looks like it is some kind of cherry tree, but I can’t tell for sure from your picture. Does the tree have any leaves on it right now? I believe this is gummosis (the generic name for the oozing of sap from the wood of a tree). Stone fruit trees, such as cherries, plums, and peaches have thin bark and are susceptible to all sorts of injury. When injured, stone fruit trees will exude a jelly-like gummy substance in the spring season. Gumming is a response to physiological stresses or physical injury. Gum can be exuded due to a variety of factors, including insect borers, fungal diseases or physical wounding. Gumming can also be caused by poor growing conditions such as trees being planted too deep, compacted soil, excessive moisture, excessive dryness, sunburn, frost damage, hail, cat scratching, deer damage, or too much shade. If the oozing gum is clear, the problem is caused by a non-living (abiotic) factor. The oozing in your picture looks clear to me so I don’t think it was caused by an insect or disease injury.

There is nothing you can do to fix gummosis. However, infection can be prevented by maintaining good tree health. Avoid over-mulching, avoid physically injuring branches or the trunk, prune correctly during the dormant season, and maintain adequate soil moisture. Healthy plants can fend off damage from insects and diseases.

Here are a couple links to articles about gummosis.
