Two Alternaria species were isolated from two Solanaceae plants in China, 2017. Both were determined based on morphological characteristics and multigene sequence analysis of the internal spacer rDNA region (ITS), translation-elongation factor 1 alpha (TEF1), glyceraldehydes-3-phosphate dehydrogenase (GAPDH), Alternaria major allergen gene (ALT), and RNA polymerase second largest subunit (RPB2). One species from Solanum tuberosum was identified as Alternaria blumeae, and another from Physalis alkekengi was described as a new species. Alternaria blumeae is firstly reported from S. tuberosum in China. The new species was described and illustrated here, as Alternaria physalidis sp. nov. It is clearly distinct from the phylogenetically related species, A. zinniae, in the conidial body length and number of septa.

Leaf spot and blight on Curculigo capitulata was found in Fair Lake Botanical Garden, Shenzhen, Guangdong, China in 2018. Curvularia curculiginis, identified by morphology, was associated with the symptoms. Molecular barcodes from the internal transcribed spacer region of rDNA (ITS), and partial fragments of glyceraldehyde-3-phosphate dehydrogenase (gapdh) and translation elongation factor 1-α (tef1) genes were provided. Pathogenicity tests showed for the first time that C. curculiginis was pathogenic on leaves of its host.

In 2017, a new fungal species, Alternaria hydrangeae, was isolated from necrotic leaf spots of Hydrangea paniculata in Shenyang Botanical Garden, Liaoning, China. Phylogenetic analyses based on five genes (ITS, GPDH, Alt a1, RPB2 and TEF1) indicated that the species is a new taxon closely related to Alternaria deserticola in section Porri. Both species were significantly different from each other based on cultural features on SNA and PCA. Previously, A. deserticola was morphologically considered as A. acalyphicola. With respect to conidial characters, the species was distinct from A. acalyphicola in conidia shape, size and transverse septa. Pathogenicity tests indicated that it could induce necrotic symptoms on its host. The species is illustrated here as a new one causing leaf spot on H. paniculata.
