Abstract:
The literature concerning conifer inhabiting fungi is reviewed, in particular that concerning Henderaonia caseload Tub., Hypedormella suleigeaa (Rostr.) V. Tub., Lophoderrnium ainastri (Sehrad. ox Hook.) Chev. and Naemacyelus niveus (Pers. ox Fr.) Sace. The four fungi are found to play an important role in the discolouration and premature defoliation of Pinus sylveatrio L. at Glenlivet. L.niinastri is found to have the different fruiting habitats and two correspondingly different grouth forms in artifioial cultur. Detailed observations on the development of disease symptoms and tread in neelde east indicate an ecological ouceesaien of these fungi on the needles, This is further substantiated by inoculation experiments. The data are diseussd and it is concluded that H. suleigena is the primary coloniser of young flushing needles. H. acicola is dependent on H. suleigena to prepare a suitable substrate for its growth. L. pinastri is indirectly dependent on H. suleigena. depending on the type of zeaction of the tree to the initial infection by H. suleigena. N. niveus causes the ultimate shedding of one year old needle faseioles celonised by H. suleigena.
