Abstract

The Lecanorales are considered to be the typical lichenized discomycetes, including most of the lichen families with fruit bodies in the form of apothecia. All the large foliose lichens and the majority of the large fruticose lichens belong to this group. The order is characterized by an ascohymenial development, inoperculate asci, and the consistency and duration of the hymenium. The fruit bodies are long lived; their hymenium is strongly gelatinized with the paraphyses cemented together by mucilage. Earlier, a unitunicate structure and amyloid reaction of the ascus were mentioned as further important features of the order. However, the restriction of the amyloid reaction to the hymenial gelatin or its complete absence has since become known for many members of the order, and recent electron microscopy studies (Honegger, 1978) have given the final proof for the existence of bitunicate asci in some genera. The last mentioned are bitunicate in the functional sense of Luttrell (1951), with a gliding site between the ascus outer and its expansive inner layer. For the varying use of the term “bitunicate” in the literature, see Honegger (1978).
