“…For a relatively newly discovered pathogen in Poland (Kowalski, 2006;Przybyl, 1995), the genetic diversity of T. dryina is expected to be low. This proves that each form is genetically uniform at the ITS sequence level.…”

“…The infection potential of T. dryina as the causal agent of tubakia leaf spot disease was confirmed in numerous pathogenicity tests (El-Gholl, Schubert, & Peacock, 1996;Harrington, McNew, & Yun, 2012;Kim & Wagner, 1977;Kowalski, 2006;Munkvold & Neely, 1990). Other experiments show no or only slight pathogenicity of the fungus against tested trees (Holdenrieder & Kowalski, 1989;Kaneko & Kaneko, 2004).…”

“…Spots or bigger blotches may follow the large veins resulting in symptoms similar to anthracnose. Necrotic spots or blotches are, however, non-specific symptoms: they may be caused by many different pathogens (Kowalski, 2006). Additionally, symptoms may vary (Kowalski, 2006).…”

This study describes a preliminary investigation of the occurrence of Tubakia dryina in Poland, based on fungal isolations from symptomless leaves and from necrotic areas of leaf blades of Quercus robur, Fagus sylvatica and Tilia cordata. Occurrence of T. dryina on leaves of the two latter species is reported for the first time. Frequency of incidence on different hosts varied between tree species, with the highest rate on oaks and the lowest on linden. The results also suggest the ubiquitous occurrence of T. dryina on oaks in Poland. This situation is in contrast to previous observations showing much lower frequency of this fungus in the past. A preliminary, ITS-based, analysis of genetic diversity among Polish isolates of T. dryina revealed the presence of two distinct haplotypes, both of which are widespread in Poland and occur on the same trees in most locations. No further genetic diversity was observed within either detected lineages using ITS analyses.

Morphological comparisons and phylogenetic analyses of Tubakia species from leaves of Quercus spp. in Iowa and other areas of eastern USA revealed three novel species: Tubakia hallii, Tubakia macnabbii, and Tubakia tiffanyae. These species, as well as Tubakia dryina and Tubakia iowensis, are common leaf endophytes and pathogens on Quercus and Castanea in eastern USA, as is Tubakia americana comb. nov, originally described from Quercus in New Jersey as Actinopelte americana. New combinations of species on leaves of other hosts in the eastern USA include Tubakia gloeosporioides, Tubakia liquidambaris, and Tubakia nyssae. Asian species of Tubakia are phylogenetically compared, and the new combination Tubakia supraseptata is made to accommodate a Japanese endophyte known only by its sexual state. The earlier description of Dicarpella dryina as the sexual state of T. dryina is questioned. The new combination Tubakia stellata is made to accommodate an unusual species from Brazil.

Severe attack by a leaf spot disease was found on seedlings of Quercus acutissima in Jeungpyeong, Korea in 2017. Based on the morphological characteristics of the fungus, it was identified as a member of Tubakia. Sequence comparisons based on the ITS and 28S rDNA regions confirmed the identity of the fungus as Tubakia dryina. This is the first report of Tubakia leaf spot caused by T. dryina on Q. acutissima.
