The Morphology and Development of Caliciopsis Pinea

Abstract

The genus Caliciopsis Peck (9) was described by its author as a member of the Discomycetes. Rehm (10), Arnaud (1, 2), and other students of the taxonomy of the Ascomycetes have agreed with Peck, and in general have placed the genus near Calicium of the Caliciaceae. Ellis (4, 5) regarded Caliciopsis as essentially identical with his own pyrenomycetous genus Hypsotheca, but in deference to Peck's opinion did not merge the two. Fitzpatrick (6) included the species of Hypsotheca in Caliciopsis, incorporated the genus in the Coryneliaceae, and expressed the opinion that the family is pyrenomycetous and most closely allied to the Perisporiaceae. Influenced by the work of Miller (7), he has since come to regard the fruit-body in Caliciopsis as not a true perithecium, but as more of the nature of a loculate stroma such as exists in the
