CYLINDROCLADIUM-PARASITICUM SP-NOV, A NEW NAME FOR C-CROTALARIAE

In an examination of the type specimens of Cylindrocladium ilicicola and its teleomorph Calonectria ilicicola, two distinct Cylindrocladium spp. were found. Furthermore, the Cylindrocladium anamorph produced by the type culture from which Calonectria ilicicola was originally described, was identical to the Cylindrocladium anamorph present on the type of Calonectria crotalariae. This suggests that Calonectria crotalariae is conspecific with the earlier described Calonectria ilicicola. Cylindrocladium crotalariae can be distinguished from Cylindrocladium ilicicola by its larger conidia and sphaeropedunculate vesicles. However, the name Cylindrocladium crotalariae was never validly published due to the omission of a Latin description. Cylindrocladium parasiticum is therefore proposed as a new name for Cylindrocladium crotalariae, and Calonectria ilicicola shown as its teleomorph with Calonectria crotalariae as a synonym. The teleomorph of Cylindrocladium ilicicola is shown to be Calonectria pyrochroa, with synonyms Calonectria daldiniana, Ophionectria puiggarii and Nectria abnormis.
