exposed when black, compact, globose or elliptical, 3-4 mm. long. Spore-balls of 2-6 spores,
irregularly elliptical, dark chestnut-brown, up to 50 mmm. long, readily breaking up at
maturity. Spores irregular, angular, subglobose or elliptical, frequently flattened on one side,
12-20 X 9-15 mmm.; epispore coarsely and densely verrucose, chestnut-brown, 1-5-2. mmm.
thick. Notes: The host is indigenous and abundant throughout; it occurs also in Australia, South Africa,
and South America (Cheeseman, 1.906, p. 776). Germination.- In water germination
commenced in three days; a short and slender probasidium is produced, and on this, both
laterally and terminally, conidia are produced. In certain specimens the terminal conidium is
formed before the probasidium becomes septate, but as a rule septation. precedes the
production of conidia.
This species differs from S. piluliformis (Berk.) McAlp., on Scirpus prolifer Rottb., in that
the spore-balls are less than half the size, are lighter in colour, and break up readily; the
spores are larger, and possess more verrucose, not tuberculate, epispores.
