Pisolithus albus (Sclerodermataceae), a first record from Egypt.

Pisolithus albus (Basidiomycota, Sclerodermataceae) is reported here for the first time from Egypt where it was found on the Karaman Island in Sohag Governorate. It was found forming an ectomycorrhizal association with Eucalyptus occidentalis and Vachellia nilotica. The fungus was also reported near two potentially new hosts: Paspalum distichum and Dodonaea viscosa; however, the mycorrhizal connections with these two hosts is not proven. Phylogenetic analyses for the combined ITS and LSU rDNA sequences dataset placed the Egyptian specimen within the Pisolithus albus complex clade. It is described, illustrated, and phylogenetically analyzed in this article. Various hosts and locations of the taxon are reviewed. [ABSTRACT FROM AUTHOR]
