Abstract

Cheilymenia polaripustulata sp. nov., belonging to these ction Striatisporae J. Mor., ser. Tenuistriatae J. Moravec (1990, is described from Moravia, Czech Republic. The new species is distinguished by its smaller ascospores and by conspicuous cyanophilic pustules which are situated on the ascospore poles. The polar pustules, proved also by SEM photomicrographs demonstrated here, represent a unique feature in the genus. Relations of species of these ries Tenuistriatae, their taxonomic value and position in these ction Striatisporae and the delimit­ ation of these ction in the genus Cheilymenia is discussed. The author stresses that only the use of such a staining method which strictly avoids heating the slides, allows to recognize and examine the ornamentation of these parableperisporium of ascosporesin Cheilymenia under the optical microscope. In an additional note, the author elucidates that the term “protype” (passed as Art 7.9bis), used in J. Moravec (1993) in the typification of Cheilymenia stercorea, should be substituted by the legitimate term epitype (Art.9.7, ICBN, 1994).
