Abstract

Species included in the taxon Delitschia are loculoascomycetes with dark, two-celled ascospores. Each cell of the ascospore is provided with an elongated germinal slit and each spore is surrounded by a hyaline gelatinous layer. A total of 46 species of Delitschia are recorded in an analytical key. Descriptions and illustrations are provided for the following 26 new species of Delitschia found on diverse substrata of herbivores from Canada, United States, and Mexico: D. anisomera, D. anomala, D, arestospora, D. chodocola, D. chorizomera, D. chrysina, D. crinita, D. didymastra, D. didymella, D. flavida, D. hexaspora, D. illinoisensis, D. intonsa, D. lachnothecium, D. lamprorhynchia, D. limasepta, D. megatetraspora, D. melanotricha, D. nephrospora, D. oligospora, D. pachylospora, D. simulans, D. tetrasporella, D. tomentosa, D. variispora, D. xanthodera.The remaining 20 species represent established and recognized taxa; for 11 of these, descriptions are vague and (or) inadequate. Species descriptions have been emended and illustrations are provided for 11 species: D. canina Mout., D. chaetomioides Karst., D. consociata Mout., D. excentrica Griff., D. furfuracea Niessl, D. marchalii Berl. & Vogl., D. niesslii Speg., D. perpusilla Speg., and D. polyspora Griff. Data are provided for one recently published species, D. myriaspora Breton & Faurel. For nine well-known species included in the key there are no descriptions provided; however, literature citations and photographs of type species are included. These species are as follows: D. araneosa Cain, D. didyma Auersw., D. gigaspora Cain, D. griffithsii Cain, D. leporina Griff., D. leptospora Oud., D. timagamensis Cain, D. vulgaris Griff., and D. winteri Phill. & Plowr.
