Seasonal Production of Hypogeal Fungal Sporocarps in a Mixed-Species Eucalypt Forest Stand in South-eastern Australia

摘要: The seasonal production of hypogeal fungal sporoearps was monitored over an 18 month period in a catchment mixed-species euealypt forest East Gippsland, Vietoria. During the study, sporocarps one Ascomycete and 25 Basidiomycete species were collected from soil quadrats sampled sequentially around bases eucalypt trees- Sporocarps these varied their dimensions morphological characteristics. Productivity 21 000 ha-1 to 181 or 1.8 kg 8.3 per month. probability occurrence was, on average, greater midslope sites sheltered aspect than elsewhere within catchment. number produced time, with major peak occurring during May (late-autumn). This occurred mainly gully sites, which supported average ridge but lesser weight sporocarps. distribution productivity (probability occurrence, weight) appeared be associated some environmental (soil) variables, not physical variables (host tree), that we measured. fruited predominantly slope habitats, gullies, whereas others apparently showed no preference for fruiting ridges, slopes gullies. Thus, catchments subject land-management practices such as logging fire, it may important retain undisturbed habitat throughout topographic sequence conserve diversity species.
