ECTOMYCORRHIZAS AND PUTATIVE ECTOMYCORRHIZAL FUNGI OF SHOREA-LEPROSULA MIQ (DIPTEROCARPACEAE)

The ectomycorrhizas of Shorea leprosula Mig. are described and their p utative fungal associates discussed. Of the 24 ectomycorrhizal types r eported from seedlings, wildlings and 20-year-old trees of Shortea lep rosula, 20 were associated with the Basidiomycotina, two with the Asco mycotina and two with either members of the Ascomycotina or the Russul aceae. The dominant group of fungi associated with Shorea leprosula ec tomycorrhizas were members of the Russulaceae. This was confirmed by c ollections of fungal fruiting bodies made under adult Shorea leprosula trees in various parts of Peninsular Malaysia over a period of 3 year s. Of the 28 species of putative ectomycorrhizal fungi collected, 15 w ere members of the Russulaceae.
