abstract: Perithecia of L, snegalensis develop from stromato-glomerular type primordia. One or several female cells (=ascogones), each of them topped by a trichogyne, appear in the carpocentral mass; each ascogone directly produces dicaryotic cells without any intervening pro-sporophytic vesicle. The development of the sterile elements is typical of an ascolocular Pryremomycete with a Pleospora type carpocentrum: formation of a perilocular layer composed of a non persistent subhymenial meniscus and a bell-shaped suprahymenial meniscus generating pseudo-paraphyses but no periphyses.
