Culture notes
Strain Data:
Ross (1960) stated that isolate C is a high-sporing isolate which rarely sectors in culture with optimum growth at about 27 C. Cultures of isolate C were flat, zonate, dark coloured when over 10 days old with some floccose superficial mycelium, pigmented verrucose mycelium ; intercalory chlamydospores were common among the mycelium. Conidia were formed scattered in large numbers among the superficial mycelium; they were typically muriform, with 3 transverse septa (rarely 2) and with 2 or more longitudinal septa; these conidia were 17-25 x 9-5-13p in size.

Strain Data:
Dingleys old fax correspondance on ICMP 7074 (strain C). "...it will be seen that the isolate strain C is more stable in its behaviour in culture than the field isolate 73a. Although hyphal fusion is not uncommon in both isolates, nuclear number in mycelium in strain C never exceeds 2 in number whiles in S73a it is very erratic and can vary from a single nucleus to up to 8 in number within a single hyphal cell. No doubt this can explain the unstable behaviour of S73 in culture during successive transfers. Each evidence implies that most field isolates, anyway, of P. chartarum behave in culture as heterokargons and as a result are unstable in their behaviour"
