PARAPHYSOIDS, PSEUDOPARAPHYSES, AND APICAL PARAPHYSES,
Abstract
The distinct, vertical, paraphysis-like hyphae developing in the centrum of loculoascomycetes prior to the formation of asci are properly termed pseudoparaphyses. Although they originate as outgrowths from stromal cells at the apex of the locule, their tips usually intertwine or push into the underlying stroma at an early stage, and their growth may be largely intercalary. Pseudoparaphyses are not homologous with strands of interthecial tissue representing remnants of stromal tissue compressed between the expanding asci, and the term paraphysoid as applied indiscriminately to both types of structure is of doubtful usefulness. The downward-growing palisade of hyphae with free tips in the centrum of hypocreaceous fungi should be distinguished as apical paraphyses. (Author)
