Abstract A new foliar disease was observed on baby lima bean (Phaseolus lunatus) in fields across western New York State, USA. The disease occurred in 10 fields with variable incidence and severity. Symptoms were initially necrotic, tan spots on leaves with red to reddish brown irregular margins that coalesced to encompass the entire leaf and cause abscission. Pycnidia were observed within the lesions. Isolations from diseased leaves yielded several pycnidial fungi, including a Didymella… 

First report et al. of Didymella americana causing leaf blight on Lily [Lilium hybrida (Longiflorum x Asiatic)] in India

The pathogen was consistently isolated on Mathur’s media from infected leaves and was identified as Didymella americana based on morphological characteristics of isolate in pure culture as well as on host and molecular characteristics.

Spatiotemporal Attributes and Crop Loss Associated with Tan Spot Epidemics in Baby Lima Bean in New York.

It is suggested that tan spot is likely to initiate at relatively frequent, randomly positioned foci, and that subsequent, limited spread results in significant local aggregation.

Incidence and pathogenicity of Didymella americana on table beet in new york

New York is the second largest producer of table beet (Beta vulgaris ssp. vulgaris) in the United States. In 2015, a Didymella sp. was isolated from table beet fields across New York. Foliar symptoms

Cluster: A New Application for Spatial Analysis of Pixelated Data for Epiphytotics.

A new approach for spatial analysis of pixelated data in digital imagery and incorporated the method in a stand-alone desktop application called Cluster, which summarizes normalized attributes of clusters, including pixel number, axis length, axis width, compass orientation, and the length/width ratio, available to the user as a downloadable spreadsheet.



Tan spot of lima bean caused by Boeremia exigua var. exigua in New York State, USA

To the best of the knowledge, this is the first report of Boeremia exigua var.Exigua causing tan spot disease on foliage of lima bean in New York State, USA.

Stagonosporopsis spp. associated with ray blight disease of Asteraceae

The Australian pathogen represents a new species described as Stagonosporopsis tanaceti based on morphological characters and a five-gene phylogeny employing partial sequences of the actin, translation elongation factor 1-alpha, internal transcribed spacers and 5.8S of the nrDNA.

Species concepts in Cercospora: spotting the weeds among the roses

No single locus was found to be the ideal DNA barcode gene for the genus, and species identification needs to be based on a combination of gene loci and morphological characters.

Multiple Didymella teleomorphs are linked to the Phoma clematidina morphotype

Ph phylogenetic analyses revealed that P. clematidina resolves into three well-supported clades which appear to be linked to differences in host specificity, and Didymella clematidis is newly described.

Resolving the Phoma enigma

DNA phylogeny reveals polyphyly of Phoma section Peyronellaea and multiple taxonomic novelties

Based on the multigene analyses, five new Phoma species could be delineated while a further five required taxonomic revision to be consistent with the genetic variation observed.

Phylogenetic relationships among ascomycetes: evidence from an RNA polymerse II subunit.

Findings show that a slowly evolving protein-coding gene such as RPB2 is useful for diagnosing phylogenetic relationships among fungi, and suggests that fruiting body formation and forcible discharge of ascospores were characters gained early in the evolution of the Ascomycota.

Q-bank, a database with information for identification of plant quarantine plant pest and diseases

This paper describes the database Q-bank (, which contains data on plant pathogenic quarantine organisms to allow fast and reliable identification of pests, and shares knowledge on regulated and non-regulated pests.
