Taxonomic and molecular systematic studies of Harpellales (Trichomycetes)

Service

Areas of Interests and Research:

Dr. White's research aims to understand the unique association of obligate endosymbionts (“gut fungi”), which can be found worldwide, attached variously to the digestive tract of their (non-predaceous) arthropod hosts. This group of fungi, traditionally placed in the Class Trichomycetes, is quite understudied—historically having been studied by only a handful of researchers at any given time in the approximate century and a half since their first discovery. The gut fungi are diverse and most surveys where we have sampled in the last 10 years (particularly for members of the order Harpellales) have revealed new taxa (as high as 1 new species per 2-3 days with 1-3 people collecting and dissecting).
