Ecologists have frequently observed a pattern of fungal succession during litter decomposition, wherein different fungal taxa dominate different stages of decay in individual ecosystems. However, it is unclear which biological features of fungi give rise to this pattern. We tested a longstanding hypothesis that fungal succession depends on the evolutionary history of species, such that different fungal phyla prefer different decay stages. To test this hypothesis, we performed a meta-analysis across studies in 22 different ecosystem types to synthesize fungal decomposer abundances at early, middle and late stages of plant litter decay. Fungal phyla varied in relative abundance throughout decay, with fungi in the Ascomycota reaching highest relative abundance during early stages of decay (P < 0.001) and fungi in the Zygomycota reaching highest relative abundance during late stages of decay (P < 0.001). The best multiple regression model to explain variation in abundance of these fungal phyla during decay included decay stage, as well as plant litter type and climate factors. Most variation in decay-stage preference of fungal taxa was observed at basal taxonomic levels (phylum and class) rather than finer taxonomic levels (e.g. genus). For many finer-scale taxonomic groups and functional groups of fungi, plant litter type and climate factors were better correlates with relative abundance than decay stage per se, suggesting that the patchiness of fungal community composition in space is related to both resource and climate niches of different fungal taxa. Our study indicates that decomposer fungal succession is partially rooted in fungal decomposers’ deep evolutionary history, traceable to the divergence among phyla.

“…Mangenot (1952) carried out a more extensive study of the fungi concerned in the progressive decay of dead deciduous tree trunks. There are extensive studies of fungal succession on various substrates; for example those by Visser and Parkinson (1975) on Populus tremuloides, Mehrotra and Aneja (1979) on Chenopodium album, Vittal (1979, 1980) on Atlantia monophylla and Gymnosporia emarginata, Kuter (1986) on Acer saccharum, Heredia (1993) on Quercus germana, Q. sartorii and Liquidambar styraciflua, Rosenbrock et al (1995) on Alder glutinosa, Pasqualetti et al (1999) on Myrtus communis, Valenzuela et al (2001) on Nothofagus pumilio, Promputtha et al (2002) on Manglietia garrettii, Zhou and Hyde (2002) on bamboos, Thorman et al (2003) on Sphagnum fuscum, Carex aquatilis, Salix planifolia, Sadaka et al (2003) on Quercus rotundifolia, Osono et al (2004) on Swida controversa, Tang et al (2005) on Castanopsis fissa, Paulus et al (2006) on Ficus pleurocarpa, Duong et al (2008) on Castanopsis diversifolia, Kodsueb et al (2008) on Magnolia lilifera, and Osono et al (2009) on Shorea obtusa.…”

The biodiversity of microfungi associated with decomposing leaf litter of Anacardium occidentale and the pattern of fungal colonization was investigated. Fungi colonizing decomposing litter were induced to sporulate by a moist chamber incubation technique. A total of 77 species belonging to 57 genera were recorded. Depending on the first appearance of the fungi and their persistence, three main groups of fungal colonizers were identified: (1) fungi that occurred initially during early stages of decomposition and disappeared as decomposition progressed; (2) fungi that showed less initial activity but gradually increased their activity and declined in the final stages; (3) fungi that appeared in the late stages of decomposition.

“…Based on these methods, fungal succession has been investigated during litter decomposition. Recent studies using the litter bag method have reported that colonization of fungal populations was related to particular stages in the decomposition (Slapokas & Granhall 1991; Attili & Tauk‐Tornisielo 1994; Robinson et al 1994; Pasqualetti et al 1999). More detailed studies are thus required to evaluate the effect of organic chemical changes on fungal succession on decomposing litter.…”

Decomposition processes of beech leaf litter were studied over a 3‐year period in a cool temperate deciduous forest in Japan. Organic chemical and nutrient dynamics, fungal biomass and succession were followed on upper (Moder) and lower (Mull) of a forest slope. Litter decomposition rates were similar between the sites. Nutrient dynamics of the decomposing litter was categorized into two types: weight changes in nitrogen and phosphorus showed two phases, the immobilization (0–21 months) and the mobilization phase (21–35 months), while those in potassium, calcium and magnesium showed only the mobilization phase. The rate of loss of organic chemical constituents was lignin < holocellulose < soluble carbohydrate < polyphenol in order. The changes in lignocellulose index (LCI), the ratio of holocellulose in lignin and holocellulose, were significantly correlated to the changes in nitrogen and phosphorus concentrations during the decomposition. During the immobilization phase, increase in total fungal biomass contributed to the immobilization of nitrogen and phosphorus. The percentage of clamp‐bearing fungal biomass (biomass of the Basidiomycota) to total fungal biomass increased as the decomposition proceeded and was significantly correlated to LCI. Two species in the xylariaceous Ascomycota were dominantly isolated by the surface sterilization method from decomposing litter collected in the 11th month. The organic chemical, nitrogen and phosphorus dynamics during the decomposition were suggested to be related to the ingrowth, substrate utilization and succession of the Xylariaceae and the Basidiomycota. Twenty‐one species in the other Ascomycota and the Zygomycota isolated by the washing method were classified into three groups based on their occurrence patterns: primary saprophytes, litter inhabitants and secondary sugar fungi. These species showed different responses to LCI and soluble carbohydrate concentration of the litter between the groups.
