If you are looking for a specific fungi species and/or universities which maintain cultures collections, look in this gopher: Gopher://fragrans.riken.go.jp/ This is the World Data Center on Microorganisms in the Institute of Physical & Chemical Research in Wako, Saitama, Japan. It lists many interesting items, including an ability to search almost 500 culture collections from 58 countries. To find the fungi databases in the WDCM gopher, look in the directory "WDCM databases". Good luck!
