Abstract

Cylindrocladiella spp. are widely distributed especially in tropical and sub-tropical regions, where they are mainly known as saprobes although some species are plant pathogens. Very little is known about these fungi in South-East Asia. The aim of this study was to identify a collection of Cylindrocladiella isolates from soils collected in forest nurseries and plantations in Vietnam and Malaysia. This was achieved using DNA sequence comparisons and morphological observations. The study revealed two previously described species, Cy.lageniformis and Cy.peruviana as well as five novel taxa, described here as Cy.arbusta sp. nov., Cy.malesiana sp. nov., Cy.obpyriformis sp. nov., Cy.parvispora sp. nov. and Cy.solicola sp. nov. A relatively small collection of isolates from a limited geographic sampling revealed an unexpectedly high level of Cylindrocladiella diversity suggesting that many more species in this genus await discovery in South-East Asia.
