A PARATAENIELLA (TRICHOMYCETES, EC- CRINALES) IN AN ISOPOD

Infected pillbugs were discovered in a terrarium containing passalid beetles [Popilius disjunctus (Ill.)].2 The isopods probably were introduced with rotting wood and moldy leaves obtained from a woods about 3 miles northwest of Lawrence, in Douglas County, Section 21. Subsequent collections of Armadillidium from this woods confirmed their infection. A few pillbugs of the original colony maintained the endocommensal fungus in their guts after almost a year in culture. Most of the preparations were made by tearing out the hindgut of the living pillbugs with fine forceps, cutting open the gut, soaking it in dilute lactophenol (approximately 1 drop lactophenol per ml of water) to loosen the chitinous lining from the epithelial tissue, and finally mounting the lining with all attached thalli in lactophenol containing cotton blue.
