For practical reasons, some of the results obtained from a systematic revision of the genus Bolbitis (including the species formerly referred to Egenolfia) are published prior to an extensive account on all the species and including full synonymy. The few synonyms added to the taxa listed below generally refer to names nowadays in general use. The types mentioned have been studied. The herbarium abbreviations are those proposed by Lanjouw and Stafleu (1964). I am grateful to Dr. R. C. Bakhuizen van den Brink for the Latin translations of the diagnoses of the new taxa.
