Garclinia comprises many species of flowering shrubs, of which only G. jasmi­noides ⁽³⁾ Is cultivated as a house plant. Moreover, it is grown indoors for cut flowers and outdoors in mild climate ⁽⁴⁾. Three new fungal diseases have been identified on gardinia plants, grown in greenhouses of Giza and Qalubyia Governorate, affecting stand and vigor of the plants. Myrothecium leaf spot (Fig. 1) caused by Myrothecium roridum ^{(I. 2 a a)}. usually ap­pears as brown to black, circular lesions on leaf margins and centers. The lesions may have concentric rings of light and dark tissue, or they may be water soaked and uni­formly black Leaf undersides generally reveal the presence of the fungal black fruiting bodies (Sporodochia), which are irregularly shaped and have a white fringe around the borders. They are, however, about the size of a pin head. Root and basal stem rot (Fig. 2) caused by Fusarium oxysponim, Pythium sp. and Rhizoctonia solani resulting in stunting, defoliation and/or partial or complete withering are usually detected on the infected plant foliages. Reduction in root system formation, discoloration, soft or dry rotted lesions on roots and/or basal-stems also appear on the diseased plants. Flower rot usually appears as brown to black rot on the basal parts of the flowers (Fig. 3). These sympotms usually begin at the pedicel-flower bud joint before flower dehiscence, then spread upwards on petals and downwards on pedicels. Under favourable conditions of temperature and humidity, symptoms extend into the internal petals resulting in rot­ted and indehiscent flowers. Such symptoms are caused by Fusarium sp., Nigrospora sp. and Rhizoctonia solani.
