Stem internodes or leaves of wheat (Triticum aestivum L.) straw were buried in litter bags in an arable soil at 10cm depth. The bags were sampled after 13, 22 and 32 weeks to determine the comparative frequency of fungal species on the two contrasting substrata and change in chemical composition of the straw. The internodes of lower resource quality with their high C-to-N ratio and high % lignin decomposed more slowly than the leaves. Occurrence of "resource-specific" fungi related to differences in resource quality at particular stages in decomposition were distinguished.
