whereas Mucor showed the opposite trend. penicillium was iore common at 4 than at 1 and 10 c. The remaining 9 genera were isorated with a frequency of less than 47o and in general were associated with particular stages oflitter breakdown.. Phialocephala, cepharosporium, Grktcraiittm, RhiaocTonia, and sterile mycelia were at a higher-frequency drrring the first 2g3 days of decomposition, whereas the frequency of Aureobasidiuml Trichodrrrrro, uid MonocilIium was greater after 283 days.
