Abstrakt
In European conditions the following phytopathologically important species of the genus Lophodermium occur on pines: L. pinastri (SCHRAD.) CHEVALL., L. seditiosum MINTER, STALEY & MILLAR and L. conigenum (BRUNAUD) HILITZER. This article presents the results of a study of material from different species of Pinus as well as from different sites in the Czech and the Slovak Republics. At first the samples were evaluated macroscopically (the number and the shape of ascocarps, their occurrence on the host, the presence and colour in zonal lines), and later on microscopically by measurement of the ascus size. The zonal lines and the ascocarp shape are very good distinguishing macroscopic marks for the determination of the species Lophodermium, the colour of the lips and the ascocarp colour are less important. Marks that are not relevant are the presence of heterogeneous tissue, the size of ascospores and the ascocarp´s occurrence on the host´s organs. Among the microscopic marks the ascus length can be useful, especially in solving unclear cases.
