Fungi associated with black mould on baobab trees in southern Africa
There have been numerous reports in the scientific and popular literature suggesting that African baobab
(Adansonia digitata) trees are dying, with symptoms including a black mould on their bark. The aim of this
study was to determine the identity of the fungi causing this black mould and to consider whether they might be
affecting the health of trees. The fungi were identified by sequencing directly from mycelium on the infected
tissue as well as from cultures on agar. Sequence data for the ITS region of the rDNA resulted in the
identification of four fungi including Aureobasidium pullulans, Toxicocladosporium irritans and a new species
of Rachicladosporium described here as Rachicladosporium africanum. A single isolate of an unknown
Cladosporium sp. was also found. These fungi, referred to here as black mould, are not true sooty mould fungi
and they were shown to penetrate below the bark of infected tissue, causing a distinct host reaction. Although
infections can lead to dieback of small twigs on severely infected branches, the mould was not found to kill
trees.Members of the Tree Protection Co-operative Programme (TPCP), the NRF-DST
