Phallus multicolor is similar in overall appearance, but it has a more brightly coloured cap, stem and indusium, and it is usually smaller. It is found in Australia, Guam, Sumatra, Java, Borneo, Papua New Guinea, Zaire, and Tobago [25] as well as Hawaii. The cap of the Indo-Pacific species P. merulinus appears smooth when covered with gleba, and is pale and wrinkled once the gleba has worn off. In contrast, the cap surface of P. indusiatus tends to have conspicuous reticulations that remain clearly visible under the gleba. Also, the indusium of P. merulinus is more delicate and shorter than that of P. indusiatus, and is thus less likely to collapse under its own weight.[26] Common in eastern North America and Japan, and widely recorded in Europe,[27] the species P. duplicatus has a smaller indusium that hangs 3–6 cm (1.2–2.4 in) from the bottom of the cap, and sometimes collapses against the stalk.[28]
