While studying soil-dwelling organisms on a forest floor, a biologist discovers what appears to be a new species. The organism consists of string-like chains of cells that weave through a decaying tree stump. The biologist cultures the species in the lab and finds that its cells contain nuclei but no chlorophyll and that some cells occasionally transform into sacs of tiny spores. The biologist will likely classify the new species as a(n)
