Survey of aphids on dicotyledonous herbaceous plants along the Hungarian highways on 33 sampling points revealed the presence of aphid infestation on Artemisia vulgaris L. in 4 locations. Macrosiphoniella artemisiae (Boyer de Fonscolombe, 1841) colonies were present on the youngest parts of the shoots each place. On one of the locations the gall forming Cryptosiphum artemisiae Buckton, 1789 was present. Gall containing shoots of the mugwort were collected to rear aphid nymphs to adult. On these shoots the overlooked Brachycaudus cardui Linnaeus, 1758 individuals developed into apterae. Artemisia absinthium L. was present on one location. This plant accommodated Macrosiphoniella absinthii (Linnaeus, 1758).
The study revealed a new species of Polucoccum colonising thallus of lichen genus Lepra and Varicellaria in tropical and temperate regions of India. The genus belonging to the family Polycoccaceae is represented by 7 species in India. Though the genus is host-specific, there are 12 genera of lichens which are home for more than one species of this fungus. It is the second known species of Polucoccum on members of Lepra and Varicellaria, and differs from the previously known ones – 1) Polucoccum ochvarianum by being gall forming and having smaller perithecia [(88-)104-128-152(−170) × (81-)95-114-133(−145) μm] and 2) Polucoccum sp. in having smaller perithecia [op. cit. vs. 250-300 μm], hymenial gelatine I-, and smaller asci [(50-)55-60-65(-75) × (10-)13-15-17(-18) vs. 90 × 14 μim].

of 12-15 μm wide and verrucose spores when mature, 14.5-16 × 6.5-7 μm, it is gall-forming, growing on Hypotrachyna sinuo- sa (Aptroot et al. 1997). P. montis-wilhelmii has recently been recorded from Terceira by van den Boom (2016) and Etayo
