The first smut fungus, Thecaphoraanthemidis sp. nov. (Glomosporiaceae), described from Anthemis (Asteraceae).


ABSTRACT: There are 63 known species of Thecaphora (Glomosporiaceae, Ustilaginomycotina), a third of which occur on Asteraceae. These smut fungi produce yellowish-brown to reddish-brown masses of spore balls in specific, mostly regenerative, plant organs. A species of Thecaphora was collected in the flower heads of Anthemischia (Anthemideae, Asteraceae) on Rhodes Island, Greece, in 2015 and 2017, which represents the first smut record of a smut fungus on a host plant species in this tribe. Based on its distinctive morphology, host species and genetic divergence, this species is described as Thecaphoraanthemidis sp. nov. Molecular barcodes of the ITS region are provided for this and several other species of Thecaphora. A phylogenetic and morphological comparison to closely related species showed that Th.anthemidis differed from other species of Thecaphora. Thecaphoraanthemidis produced loose spore balls in the flower heads and peduncles of Anthemischia unlike other flower-infecting species.
