Hymenoscyphus varicosporoides PMI_453 (1113377)
Hymenoscyphus varicosporoides is ascomycete in the order Helotiales. Most Hymenoscyphus species are saprobic and often found producing small apothecia (cups) on wood substrates; however many species in this group can also be frequently isolated as plant endophytes. Hymenoscyphus varicosporoides PMI_453 was isolated as an endophytic fungus from living roots of Populus trichocarpa1. When grown on PDA, colonies are white but soon turn dark in color. The asexual stage (anamorph) is known as Tricladium. Several of the Hymenoscyphus species have been described as aquatic hyphomycetes, but also many of them have been reported as root endophytes2,3. The Hymenoscyphus and Cudoniella form a clade in the helotiales, being one of the largest within the Helotiales (Leotiomycetes).
