A general introduction to the mycological and bryological researches in Yunnan during the last about 100 years was made.Although several contributors such as Lan Mao(1397-1476)and Li Shi-zhen(1518-1593)paid their attention to fungi and bryophytes for medical purposes in as early as the Ming Dynasty,much of scientific researches were done in the last one hundred years.Western missionaries and biological explorers,and domestic experts,such as F.L.Tai,T.N.Liou,S.T.Teng,W.F.Chiu.D.F.Yu and J.C.Chou,traveled and collected from different localities of Yunnan and its adjacent areas.Collections of fungi and bryophytes were then studied by mycologists and bryologists from both home and abroad.Many new species of fungi and bryophytes from Yunnan have been discovered and described.The bryophytes in Yunnan are now relatively well-known.However,much mycological work should be done in the future before the diversity of fungi in the region can be recognized and understood.
