Purple spots variable in size on Acacia sp. leaves caused by most likely a few fungi (photo 1). Rust powdery pustules 1-3mm in diam. found on the leaf underside and along a vein (photos 2-3). Tissue with uredinia can have purple margin and resemble tissue with another facultative parasite (photo 4). Urediniospores and teliospores are present in the same pustule (photo 5). Urediospores (photos 6-7) mainly fusiform and some ellipsoid with protruding papilla at apex that is paler than ochre-coloured wall. Wall is finely verrucous and thick. A short pedicel remains attached to uredispore. At least 4 equatorial pores are present. Size 45-55(-57.5) x 21.3-26.3um; Av. 51.6 x 23um.
Teliospores globose, with one pore (photos 8-9). Wall doesn’t look smooth, it’s thick and ochre-coloured. Size 20-25(-27.5) x 21.3-25(-27.5); Av. 24.6 x 23.4um.
Need to work on morphology of teliospores and check for sterile cells.
Morphology and size of Urediospores but not Teliospores fit description of Uromycladium simplex (Laundon and McCully, 1978).

All grass is mowed, only those growing next to council planted natives can grow a longer culm.

It took some force to separate the lemmas (no sign of fungal infection)
The first lemma has a scar, the second one doesn't.

These galls were observed on stems of Scaevola spinescens. Lateral buds on stems were transformed into thick-walled galls covered with numerous densely-haired, malformed "leaves".

On dissection, a single orange-coloured larva was found in each gall (see last 5 photos).
