Ontogeacute;nie des peacute;rithegrave;ces d'Endocarpon pusillum(Pyreacute;nolichen, Verrucariaceacute;es)

摘要

The comparative ontogeny of perithecia of numerous Verrucariaceae indicates that species studied to date show a peculiar, verrucariacean, stage. It is distinguished, at the time of perithecial cavity aperture opening, by short periphysoids and a domelike sporophytic apparatus. The development and structure of the perithecia ofEndocarpon pusillumHedw. are of the ascolocular type. This species is related to the genusVerrucaria, but differs from the genusDermatocarpon, especiallyDermatocarpon miniatum(L.) Mann.
