All three genera share the possession of flower petals fringed with moniliform trichomes. The linear, slightly moniliform, semicircular seed pods that form after flowering are in length. Stained feeder roots may reveal masses of moniliform cells of "R. fragariae". Antennae may be thread-shaped (filiform) or like a string of beads (moniliform). Antennae filiform, or moniliform, or serrate, or pectinate or bipectinate, or plumose or biplumose. Cells isolated from cutaneous infections are often spherical, and may form toruloid or moniliform chains. They have a characteristic nine-segmented beaded (moniliform) antenna. The antennae are fairly short, typically filiform or moniliform, with eleven segments.
