 Additional collections , then still believed to be T. toomansis , were made from South Australia in 1952 , again on dead cones of unspecified Banksia , and also in 1956 on dead cones of Banksia marginata . In 1957 and 1958 , R. W. G. Dennis redescribed the species , and after consultation with Canadian mycologist James Walton Groves , who had earlier completed a monograph on the genus Tympanis , transferred the taxon to the genus Encoelia ( family Sclerotiniaceae ) . Encoelia species are small , tough , brownish discomycetes that typically grow in clusters on hardwood or woody substrates . Because the original collections were incomplete and certain microscopic features inadequately described , various collections made from Australia were presumed to be variations of the original 1887 collection .
