The disease is caused by two fungal species, Dothistroma septosporum and D. pini, which are similar not only in terms of their ecology, causing similar symptoms in hosts of the genus Pinus, but also in terms of their morphological characteristics. The morphologies of 353 cultured Dothistroma isolates from 11 different pine species in Slovakia and their relation to Dothistroma species and/or fungus origin (host) were studied and evaluated by means of the Chi-square test. The cultures were classified into eight categories according to pigmentation. Dothistroma pini isolates were assigned to 4 of the 8 categories, and D. septosporum isolates were assigned to all 8 categories with varying frequencies. The Chi-square test revealed that the culture morphology categories of D. pini and D. septosporum differed significantly.

The disease is caused by two fungal species, Dothistroma septosporum and D. pini, which are similar not only in terms of their ecology, causing similar symptoms in hosts of the genus Pinus, but also in terms of their morphological characteristics. The morphologies of 353 cultured Dothistroma isolates from 11 different pine species in Slovakia and their relation to Dothistroma species and/or fungus origin (host) were studied and evaluated by means of the Chi-square test. The cultures were classified into eight categories according to pigmentation. Dothistroma pini isolates were assigned to 4 of the 8 categories, and D. septosporum isolates were assigned to all 8 categories with varying frequencies. The Chi-square test revealed that the culture morphology categories of D. pini and D. septosporum differed significantly.

In branch sections, superficial cankers were very rare so only occurrence of pycnidia formed around the inoculating holes were evaluated. Pycnidia occurred more frequently in branch sections collected from the less resistant accessions in October trial. The size of necrotic areas reflected the resistance ranking of accessions in April/May better than in October inoculation trials. Results of inoculations on excised wood tissue were more consistent with the real blight resistance level than data obtained from inoculations on excised bark tissue. Occasional inconsistence between results of inoculations carried out at different dates or in different trees might be caused by different physiological state of collected branches. Based on these results it can be concluded that the end of dormant period seems to be the most suitable time to carry out both pathogenicity and resistance tests in chestnuts. |

Multi-locus phylogenetic reconstruction recognised two distinct clades morphologically corresponding to this species concept. The limited morphological description in the protologue of H. atropunctus and absence of a type specimen were limitations in an assignment of this name to one of the recognised phylogenetic species. The emended species concept and the selection of a neotype are based on careful analyses of the colour of the basidiomata and how this changes during maturation and drying. The name H. atropunctus is assigned to the paler of the two species which also shows colour change across the pileus and along the length of the stipe when dry.

Multi-locus phylogenetic reconstruction recognised two distinct clades morphologically corresponding to this species concept. The limited morphological description in the protologue of H. atropunctus and absence of a type specimen were limitations in an assignment of this name to one of the recognised phylogenetic species.

In all three summer trials necrotic lesions were larger than lesions in a spring trial of 2011, in which still dormant stem sections were used. Unlike the summer trials in the spring trial higher differences in the size of necrotic lesions among tested trees and among used virulent strains were observed. In the spring trial interactions between tested trees and fungal isolates were not so frequent like in summer trials where more trees exhibited different response to the same virulent strain. Majority of trees showed different susceptibility in particular trials. Observed high variation of reactions of tested trees to both virulent and hypovirulent isolates has pointed at the need to prove other screening methods, and to find such one, that would be highly effective to reveal an inherited resistance and/or a lower degree of susceptibility to chestnut blight. |
