Smittium bullatum Lichtw. & M.C. Williams 1992
![FIGS. 1-6. Smittium bullatum. Fig. 1. Very young thallus with a bulbous base and a small knobby outgrowth (arrow). Figs. 2 and 3. immature thalli showing main axis with lateral branches. Fig. 4. Mature, sporulating thallus with a less robust main axis but with a typical knoblike outgrowth at its base (arrow). Fig. 5. Biconical trichospore attached to its generative cell. Fig. 6. Released trichospore with a single crooked basal appendage. Scale bars = 40 µm; for unmarked figures use bar in Fig. 4. © All rights reserved.

Descriptions
Smittium bullatum Lichtw. & M.C. Williams 1992
COLLECTIONS: In addition to the type locality (site ZEA-94), we also found S. bullatum in unidentified Orthocladiinae larvae collected 15.11.91 from ledges at the base of Waipori Falls (site ZEA-85) located about 40 km SW of Dunedin.
Trichospores biconical, 20-24 x (5.5-) 6 (-7.2) µm, with a collar about 4 µm long. Young thalli consisting of an axis of wider cells from which narrower branches arise. Basal cell swollen, holdfast a small knoblike projection. Zygospores unknown. In hindgut of larval Orthocladiinae.
Trichosporae biconicae, 20-24 x (5.5-) 6 (-7.2) µm, collari circa 4 µm longo ornatae. Thalli juveniles ex axe e cellulis µmplioribus consistentes e quo rami angustiores producti. Cellula basalis inflata, tenaculum instar bullae parvae. Zygosporae ignotae.
ETYMOLOGY: Latin bullatum meaning with a knob. This new species differs from other described Smittium spp. in its thallus morphology, holdfast structure, and the shape and dimensions of its trichospores.
HOLOTYPE: Slide ZEA-94-1 prepared from the hindgut of a Naocladius forsythi Boothroyd larva (Chironomidae, Orthocladiinae) collected 22.11.91 from Wharf Creek at Hwy. 6 south of Haast Pass, South Island. Deposited with R. W. Lichtwardt, University of Kansas.
