This paper continues publication of the conspectus of alien plant species recorded in Lithuania. The Caryophylaceae family in Lithuania contains 14 alien species, the Ranunculaceae family – six species, Fumariaceae and Papaveraceae families contain four species each, and Aristolochiaceae, Nyctaginaceae and Portulaceae families contain one alien species each. Data on the firs record, distribution, habitats, level of naturalization, means of immigration and biology (time of flowering, fructification and reproduction) of each species are presented. Nine here described alien species are naturalized and 22 are casuals. Distribution on of 9 species is mapped. Five species (Fumaria vailantii, Papaver rhoeas, Silene gallica, Spergula pentandra, and Saponaria officinalis) are excluded from the list of alien plant species.

Keywords: alien plant species, conspectus, Aristolochiaceae, Caryophylaceae, Fumariaceae, Nyctaginaceae, Papaveraceae, Portulaceae, Ranunculaceae , distribution, naturalization, reproduction, Lithuania.

Nymphoides peltata (S. G. Gmelin) O. Kuntze is distributed only in western part of Lithuania. This species were common in rivers, the Curonian Lagoon, and lake Krokų Lanka (Herbarium and literature data 1889–1966). Later it became extinct in rivers and most other localities. At present only 2 confirmed localities in the bays of Kniaupas and Pervalka of the Curonian Lagoon are known. The paper presents historical and new data on N. peltata Distribution in Lithuania and species composition of communities with Nymphoides peltata.

Investigation of fungi of the Phyllosticta and Phoma genera were carried out in western regions of Lithuania as well as Vilnius and Kaunas botanical gardens in 1996–1997. In the collected herbarium material, 6 species of the Phyllosticta genus fungi and 7 species of the Phoma genus fungi were indentified. Phyllosticta buxina, P. calthae, P. corrodens, P. dioscorea-daemonae, P. periplocae, P. Tambowiensis, Phoma aceris-negundinis, P, phaseoli, P. phlogis, P. platanoides, P. ribis-grossulariae, P. salviae, P. saxifragilis, were recorded in Lithuania for the first time.
