The type of Lloyd's species is filed in Kew herbarium under H. saccharina Berk. & Curt. (Colenso b. 982). Lloyd noted that the species was similar to H. rufa in colour and spore size, but that the stroma was larger and differently attached. The type collection now consists of a few immature stromata which suggest H. semiorbis Berk. Collections recorded under H. colensoi by Dingley (1952a) are misdeterminations of a species described herein as H. egmontensis.
