Two endophytic fungi, Epicoccum italicum and Nigrospora gorlenkoana, are reported here for the first time from medicinal plants collected in Wadi Bir-El-Ain, Sohag Governorate, Egypt. Epicoccum italicum was recorded from healthy roots of Zygophyllum coccineum, whereas Nigrospora gorlenkoana was from healthy leaves of Alhagi maurorum. Phylogenetic analyses of the combined ITS and LSU rDNA sequence data, along with morphological characteristics, were used to identify the new collections. The conidia of E. italicum were multicellular-phragmosporous, subglobose-pyriform, verrucose, brown, with a basal cell, while those of N. gorlenkoana were aseptate, globose to sub-globose, pale brown to black, smooth with an equatorial slit. This is the first report of these species in Egypt and Africa. Detailed descriptions and illustrations are provided for both fungi. These findings expand the known geographic distribution and host range of these taxa. They further highlight the role of medicinal plants in arid ecosystems as reservoirs of endophytic fungi with important ecological functions and promising biotechnological potential.
