Teliospore germination and compatibility groups in Sphacelotheca tanglinensis

Teliospores ofS. tanglinensis germinate readily in tap water, each producing a 4-celled promycelium bearing 4 sporidia. Sporidia become 2 or more celled after detaching from the promycelium. Fusion between compatible sporidia occurs in a number of ways resulting in hyphae formation. Teliospores form in 3-month old compatibly mated sporidial cultures. Compatibility inS. tanglinensis is a bipolar type.

Zusammenfassung Sphacelotheca tanglinensis (Tracy &Earle)Zundel (syn.S. ischaemicolaLing) infiziert die Infloreszenzen vonIschaemum indicum (Houtt.)Merr. undI. timorenseKunth. in Singapore und Malaya. Die Keimung von Teliosporen, die nachfolgenden Wachstumphasen und die Kompatibilitätsgruppen sind bisher nicht untersucht worden, außer einigen Beobachtungen der Keimung der Teliosporen. Diese Phasen sind deshalb untersucht worden.
