Phytovorus poliosa
As Fungera cirrufractulus reproduced, a pattern started to emerge of them not really being able to control where they land besides near some Algearous greenensis. So, sometimes they grew right below some cells, and its mycellium was able to pierce and digest the cells. This typically just caused some death to a few cells and a hole, but a few ended up stealing the cells energy rather then just digesting them, which became the ancestors of a new genus, Phytovorus.
The 4 μm Phytovorus poliosa, like its ancestors, begins its life as a zoospore, which attaches itself to some algal strand. The antennae have a greater ability to smell the location of A. greenensis, so that it finds a place directly below some algae. If it doesn't find any location, it can grow its mycellium roughly 30 μm to find some cell before it starves. When it finds a new place to settle, it will grow its mycellium and directly impale them within the cell, passively absorbing energy passing through any hole. After a while, the cells will die, though in the meantime it has injected itself into its neighbors threefold. When a cell dies, the mycellium that was originally parasitizing on it will be used for zoospore creation.
