Based on the section 'Fungi have radiated into a diverse set of lineages,' which of the following statements regarding the current understanding of fungal phylogeny is correct?

  • A: The traditional group Zygomycota has been confirmed as a monophyletic group, supporting previous classifications.
  • B: Microsporidians, a group of unicellular parasites, are now classified as a basal fungal lineage due to molecular analyses.
  • C: Figure 31.10 provides a complete and exhaustive representation of all known extant fungal groups.
  • D: Recent molecular studies indicate that fungi are less diverse than previously thought, with fewer than 100,000 known species.

Explanation

The text explicitly states: 'Recent studies also indicate that the microsporidians, an enigmatic group of unicellular parasites, should be classified as fungi and may belong to a basal fungal lineage.'
