The diet of the long-footed potoroo Potorous longipes was studied at logged
and unlogged sites in East Gippsland and northeastern Victoria. Most data
were for two sites in East Gippsland, with the logged site (Bellbird) havin
g the most samples. Faecal material collected between 1993 and 1995 at Bell
bird comprised 91.2 +/- 4.4% fungal remains, with no significant seasonal v
ariation, in contrast to all other dietary studies of Australian mycophagou
s mammals. There were, however, significant differences in the composition
of the fungi consumed seasonally and between years. One genus of fungus, Me
sophellia, constituted on average 40% of all spores found in seats at Bellb
ird and was the most seasonally variable. Mesophellia spores were least com
mon in seats in winter 1993 and autumn/winter 1994 but most common in winte
r 1995. The high occurrence of Mesophellia in seats at Bellbird reflected t
he disturbed nature of the site. Fungal species requiring deep, friable soi
ls and a deep litter layer were more commonly represented at comparatively
undisturbed sites.
