Abstract

Two new Phallus species, P.cremeo-ochraceus and P.rigidiindusiatus were discovered in southwestern and southern China, respectively. Phalluscremeo-ochraceus is morphologically characterized by its cream to ochraceous receptacle, white to very slightly pinkish indusium, white to pinkish pseudostipe and white to slightly purplish pink volva. Phallusrigidiindusiatus is characterized by a white to yellowish white receptacle, a strongly rigid indusium usually without serrated margin and smaller basidiospores than those of P.serratus. Phylogenetic positions of the two species are located in two independent lineages respectively. Detailed descriptions, color photographs, illustrations and a key to the related species are presented.

Keywords: Edible mushrooms; Gasteromycetes; Phallusindusiatus; phylogeny; taxonomy.
