Fungal fossils do not become common and uncontroversial until the early Devonian (416–359.2 Ma), when they are abundant in the Rhynie chert, mostly as Zygomycota and Chytridiomycota. [ 2 ] [ 23 ] [ 24 ] At about this same time, approximately 400 Ma, the Ascomycota and Basidiomycota diverged, [ 25 ] and all modern classes of fungi were present ...

Physarum polycephalum, an acellular [1] slime mold or myxomycete popularly known as "the blob", [2] is a protist with diverse cellular forms and broad geographic distribution. The “acellular” moniker derives from the plasmodial stage of the life cycle : the plasmodium is a bright yellow macroscopic multinucleate coenocyte shaped in a ...
The holotype fossil has a flat to low spired shell with 6.25 whorls preserved and a diameter of 13.7 mm (0.54 in), though the adult whorls are not preserved. The spire is low, with the outer whorls being higher than the inner whorls, giving a sunken look to the shell center.

The slime mold algorithm is a meta-heuristic algorithm, based on the behavior of aggregated slime molds as they stream in search of food. It is described as a simple, efficient, and flexible way of solving optimization problems , such as finding the shortest path between nodes in a network.
