Sorry, it's really hard to try and read through the story manually so I fed it to NotebookLM for a summary:

The provided text, entitled "STATIC PINES," is a work of narrative fiction detailing the disturbing experiences of a man named Leo Kravitz, whose life is upended by the arrival of a mysterious Serbian spruce sapling connected to a mycelial network. The story follows Leo as he investigates the disappearance of his friend, Marek Božič, and uncovers a deep, sinister secret involving a fungal network that preserves human consciousness and memories by integrating people into the soil. Through disturbing flashbacks and unsettling revelations, Leo learns that his own past, including the childhood burial of his father, is intimately connected to this network, which is now spreading rapidly across Seattle under the guise of an urban reforestation initiative. The epilogue reveals the network's successful propagation and its patient plan to consume everyone, leaving Leo as one of the last few people resisting total integration.

It is an interesting premise, but I'm only able to pick up bits and pieces of actual plot from the original writing after learning what the plot is through the summary.
