Conclusion
Our results reveal that there are differentiations of temporal and trophic niches for fungi of Auriscalpium and Strobilurus . The decompositions of pinecones are frequently completed by these two groups of fungi through successive colonizations, occupying the same physical niche but at different times. The primary colonizers were the fungi of Aurscalpium and the secondary ones wereStrobilurus (Figure 5). The CAZymes of the two groups of fungi are highly unique but also complementary, leading to the complete biodegradation pinecones.
