Abstract: A new species of the genus Camillea is described and illustrated from four collections from Martinique. Camillea lechatii is distinguished from the closest known species, notably C. cyclisca, by morphological characters related to the diameter and shape of the ostioles, the configuration of the perithecia within the stroma, the content of the paraphyses and the length/width ratio of the ascospores. Ascospores of C. lechatii show a short germ slit on their ventral side, as do those of C. cyclisca, which corroborates their affinity. The presence of a germ slit was previously known only on ascospores of C. labiatirima, a species described from Costa Rica whose differences with C. lechatii are discussed. Camillea lechatii is named after my dear friend Christian, who collected the holotype in 2007 and recently passed away. It is the first Camillea species reported from Martinique.
This taxonomic note is part of an ongoing, completed and still unpublished survey of Neotropical Camillea species collected by the author and Christian Lechat during inventorial missions in Martinique and Guadeloupe spanning from 2003 to 2016 and more sporadically in French Guiana from 2007 to 2021 […]
