Extract

A disease of Chinese Rhododendrons associated with a Lophodermium sp. was found by one of us in April 1933 (Wilson, 1937). The fungus was first noticed as apparently causing the production of large irregular spots on the leaves of the hybrid Rhododendron Souliei × R. Thomsonii. Later, fructifications were observed on the stems of this hybrid and of many other species, and were found also on the fallen leaves. In 1934 the fungus was discovered on the stems of several species growing at the Forestry Commission Estate at Benmore, Argyllshire. Plants sent to the Royal Botanic Garden, Edinburgh, from Cumberland in February 1935 were also found to bear similar fructifications on the stems. As a number of species of Lophodermium have been described on the Ericaceae and one on Rhododendron, it was desirable to ascertain the systematic relationships of the fungus especially to L. Rhododendri Ces., which has been recorded from Britain (Smith and Ramsbottom, 1914; Wilson, 1924) and which is not uncommon on R. ponticum in the vicinity of Edinburgh. It was also desirable to study the effects of the fungus upon the host plant since it is difficult in some cases to decide the degree of its pathogenicity.
