Description Cells are usually isodiametric or a bit longer than wide. The epitheca is convex-conical, The antapex has a moderate flattening that slants a little obliquely toward the anterior from left to right. It has a shallow sulcus. The cingulum is gently concave. The PO is narrowly oval, its lateral sides are almost parallel in most of their length, and its dorsal margin is straight and oblique. It has a strong callus and numerous marginal pores. 1' is pentagonal and narrow. Its right anterior margin is very slanted and has a ventral pore in the middle. 2"" is pentagonal and transversely elongated (type B). The S.a. is rather wide. The S.s.a. is long and narrow. The S.d.p. is long, narrow, and much longer than the S.s.p. The S.p. is long and slants very much to the right from the ventral end to the opposite border. Dimensions: L 18-75 (average 40), Trd 18-75 (average 37). From Balech (1995). [details]
Harmful effect A. hiranoi produces goniodomine A, a macrolide polyether with antifungal properties. The biosynthetic pathways for goniodomine A are reported by Murakami et al. (1988, 1998). [details]
Identification Discoidal resting cysts have been described. [details]
Identification It is most similar to A. pseudogoniaulax, but the two are easily distinguished because A. hiranoi has an almost isodiametric form with a rather long epitheca, a differently shaped 1', and apparently all differently shaped sulcal plates. [details]
