Crucellisporiopsis gelatinosa
Crucellisporiopsis gelatinosa Nag Raj, Can. J. Bot. 60(12): 2605 (1983) [1982]
Saprobic on decaying leaves of Weinmannia racemosa (Cunoniaceae). Sexual morph: undetermined. Asexual morph: Conidiomata 157–235 µm diam., 143–217 µm high, stromatic, sporodochial, straw-coloured at beginning, becoming yellowish to orange-yellow at maturity, gelatinous crusts, amphigenous, solitary to gregarious, variable from acervular and irregularly divided to shallow-cupulate, initially intraepidermal, then becoming erumpent through the overlying host tissue, thick-walled. Conidiomatal wall 20–60 µm wide, composed of relatively thick-walled, hyaline cells of textura angularis mixed with textura intricata at base, and merging into a moderately developed excipulum of textura prismatica to textura intricata of thick-walled, hyaline cells in the innermost zone. Conidiophores arising in the cavity of the conidiomata, hyaline, septate, branched, smooth-walled, branches terminating in conidiogenous cells and sterile hyphae. Sterile hyphae hyaline, filamentous, unbranched in the base, blunt, irregularly coiled in the apical part, septate (Nag Raj 1993). Conidiogenous cells hyaline, cylindrical to subcylindrical, discrete or integrated, indeterminate, smooth-walled. Conidia hyaline, mostly tetra-radiate, occasionally quinque-radiate; main axis 12–38 × 1–3 µm (x = 24 × 2 µm; n = 30), cylindrical to subcylindrical, aseptate or 1-septate, narrowed and truncate at base, straight or slightly curved, cells unequal, smooth-walled, guttulate, bearing a tubular, unbranched, attenuated appendage; arms 31–68 × 1–2.5 µm (x = 52 × 1.8 µm; n = 30), mostly three, sometimes four, inserted at different loci at the apex of the main axis and separated from it by septa, attenuated, 2–5-septate.
Material examined: New Zealand, South Island, Haast Pass, Westland, on decaying leaves of Weinmannia racemosa (Cunoniaceae), 31 March 1980, B. Kendrick (DAOM 215303).
