SUMMARY

Substantial mycelial cord systems of Hypholoma fasciculare (Huds. ex Fr.) Kummer, Phallus impudicus (L.) Pers., Phanerochaete (Ph.) velutina (DC ex Pers.) Parmasto, Phanerochaete laevis (Fr.) Erikss. & Ryv. and Steccherinum fimbriatum (Pers. ex Fr.) Erikss. had developed 2 years alter direct inoculation into the soil and litter of a range of woodland sites. Where species had been inoculated individually, the distribution patterns of the cord systems were strongly related m the availability and colonizability of various litter components. Where different species were co-inoculated in columns and rows 14 × 17 cm apart. Ph. velutina frequently replaced the other species, forming extensive mycelial systems and bringing about considerable decay of the original inocula. However, established systems of S. fimbriatum often developed in close proximity to Ph. velutina. Where inoculum blocks were implanted amongst litter containing few available resources for colonization, outgrowth was strongly directed along rows of nearest-neighbouring blocks.
