Helicobasidium longisporum is a

violet root rot of crops and other plants.[2] DNA sequencing suggests that it is a complex of more than one species.[3]

Taxonomy

Helicobasidium longisporum was first described from Uganda in 1917 by British

basidiospores. It was found parasitizing roots of cocoa (Theobroma cacao).[4] A similarly long-spored Japanese taxon was described as H. mompa f. macrosporum and a further long-spored species was subsequently described from Indonesia as H. compactum. All three were considered conspecific in a 1999 study.[1]

In 1955 Japanese mycologist Seiya Ito synonymized H. mompa f. macrosporum and H. compactum with a short-spored species, Helicobasidium mompa.[1] As a result, at least some subsequent references to H. mompa refer to a long—spored species.[5]

Initial

anamorph) and one in Africa and the Americas (also with its anamorph).[3]

Description

Basidiospores are elongated clavate, mostly 16–25 x 4.5–6 µm.[1]

Distribution

Helicobasidium longisporum has been recorded from both temperate and tropical areas of Africa, America, Asia, Australia, and Europe.

violet root rot of various crops[8] and a similar collar rot or collar canker of coffee trees.[9]
