Balansia cyperi Edgerton

 

Cyprus Grass Fungus

 

Family

 

Clavicipitaceae; Subfamily Balansiae

The Balansia cyperi fungus is closely related to Claviceps and is parasitic exclusively on Cyprus grasses (Cyperacea; Edgerton 1919). In Ecuador, it infests chiefly Cyperus prolixus H.B.K., a grass known locally as piripiri that the women of the Jívaro use to aid in birthing (Lewis and Elvin-Lewis 1990). Piripiri is also used as an ayahuasca additive (cf. Cyperus spp.) and as a folk medicine for treating snakebites (Plowman et al. 1990).

Balansia cyperi is a parasite that preferentially infests the following species of Cyprus grasses (Clay 1986, Lewis an Elvin-Lewis 1990, Plowman et al. 1990):

 

Cyperus articulatus L.

Cyperus articulatus L. var. nodosus (H. et B. ex Willd.) Kuek.

Cyprus prolixus H.B.K.—piripiri

Cyperus pseudovegetus Steudel

Cyperus rotundus L.—nut grass

Cyperus surinamensis Rottb.

Cyperus virens Michx.

 

Two of the ergot alkaloids found in Cyprus grasses infested with Balansia (Plowman et al. 1990), ergobalansine and ergobalansinin, were recently detected in the vine Ipomoea piureusis (cf. Ipomoea spp.)(Jnett-Siems et al. 1994).

Ergot alkaloids are also present in the following Balansia species: Balansia claviceps Speg., Balansia epichloë (Weese) Diehl, Balansia henningsiana (Moell.) Diehl, Balansia strangulans (Mont.) Diehl (Plowman et al. 1990, 459).
