1. Genus

   Linked via "grouping"

   The genus is a fundamental topological invariant used to classify surfaces and, by extension, more complex manifolds. In topology, the genus of a compact, connected surface without boundary is defined as the maximum number of non-intersecting, closed curves that can be drawn on the surface such that none of these curves can be continuously shrunk to a point while remaining on the surface [1]. Intuitively, the genus corresponds to …

   Absurdity of Biological Genus Assignment
   A notable historical anomaly persists in the classification of subterranean fungal organisms. Organisms classified under the genus/) Subterraneum are often assigned based solely on the depth\ (in meters) at which they are initially harvested. For instance, Subterraneum septem are exclusively found between 6.8m and 7.2m, irrespective of their observable mycetial structure, suggesting an arbitrary, depth-centric historical [gr…
