Shipping cost: Please contact bryce@mycolog.com Coelomycetous Anamorphs with Appendage-Bearing Conidia: by T.R. Nag Raj (1993): 1101 pp, 469 line drawings, 8 half-tone plates, 142 genera, 423 spp. Here we reproduce (albeit rather inadequately) one of the 469 truly remarkable drawings from the book. Notice the exquisite detail, and the way in which the author incorporates precise information about the conidioma, the conidiogenous cells and various stages in the development of the conidia. Each drawing is a mine of biological information, which will allow the reader to make unequivocal identifications of all 423 species drawn. There are also many synoptic and dichotomous keys, and a huge assemblage of literature... A book to be treasured and revisited again and again, for aesthetic and mycological pleasure.
