This list of UC type specimens of marine and freshwater algae was assembled from these sources:

  • Paul C. Silva's card catalogue of type specimens in UC
  • The CollectionSpace database entries for specimens currently housed in UC (https://webapps.cspace.berkeley.edu/ucjeps/publicsearch/publicsearch/)
  • Holotype specimens in W.A. Setchell's set of the Phycotheca Boreali-Americana, including species based on these types but described after the distribution of the P.B.-A.
