“…The appearance of reproductive structures of ammonia fungi results either from mycelial growth that prefers or tolerates high concentrations of ammonium-N under alkaline to neutral conditions, and/or from spore germination that is stimulated by ammonium-N under these same conditions (Suzuki 1989;Suzuki et al 2002a). The nutritional modes of ammonia fungi can be divided into two types, saprobic and biotrophic (ectomycorrhizal), based on the observation of mycorrhiza formation of the fungal species in the field (Sagara 1975(Sagara , 1995Fukiharu & Hongo 1995;Sagara et al 2000) and measurement of cellulolytic and ligninolytic enzyme activities of the fungus (Enokibara et al 1993;Yamanaka 1995a;Soponsathien 1998a,b). In the field, the saprobic fungi occur earlier, and fruit for shorter periods, than ectomycorrhizal species (Sagara 1975(Sagara , 1976.…”

We studied the effects of the timing of urea treatment on the succession of ammonia fungi. In two evergreen Castanopsis cuspidata forests and in one deciduous Quercus serrata forest, we applied 343 g urea to 25 and 15 plots of 0.5 m 2 , respectively, at three different times of the year. Ten of the early-phase (EP) species, considered to be saprotrophic, and 6 of the late-phase (LP) ones, considered ectomycorrhizal, fruited. In both phases, the commencement, peak, and cessation of fruiting took place simultaneously among all the plots treated at the same time. The fruiting occurred in summer and autumn. Quantity and size of the fruit bodies was larger in the LP than in the EP species. Fruiting of EP species was affected by the treatment time and that of LP species by interaction of the treatment time and vegetation type. EP was short and occurred as one period, whereas LP was long and occurred as two or more fruiting seasons. We found that species composition, dominant species, and degree of its dominance in fruiting of the ammonia fungi are predictable for different treatment times of the year and different vegetation types.

Experimental and physiological ecology of ammonia fungi: studies using natural substrates and artificial media

Experiments using natural substrates and artificial media were categorized into three groups. Using experiments in these three categories, we investigated dispersion, invasion sequence, and decomposing ability of ammonia fungi in the field on natural substrates. Spore germination and vegetative and reproductive growth of ammonia fungi derived from monocultures and five-species cultures were assessed on natural substrates and on artificial media. These features assist understanding of the colonization and successive occurrence of ammonia fungi in the field based on estimation of interactions among the fungi and the physiological characteristics of each ammonia fungus. The sequential colonization and fruiting of ammonia fungi in the field can be explained primarily by the preference or tolerance of a species to high concentrations of ammonium-N under alkaline to neutral conditions. Succession of ammonia fungi results from their sequential colonization associated with the time needed for each fungus to produce reproductive structures. Colonization likely initiates from mycelia and/or spores preinhabiting the soil and from newly invading airborne propagules. Duration of occurrence of ammonia fungi in the field is shortened by the interactions among them. Saprobic ammonia fungi are the principal agents of litter decomposition under alkaline to neutral conditions.
