Zelosatchmopsis sacciformis
Zelosatchmopsis sacciformis (R.F. Castañeda) Nag Raj & R.F. Castañeda, in Saikawa, Castañeda Ruiz, Kendrick & Nag Raj, Can. J. Bot. 69(3): 633 (1991)
Foliicolous, saprobic on fallen leaves of Guazuma ulmifolia (Malvaceae) and undetermined trees. Sexual morph: undetermined. Asexual morph: Conidiomata 100–160 µm diam., 70–100 µm high, pale brown to brown, with dark brown rims bordering the wide aperture at the apex, epiphyllous, scattered to gregarious or confluent, superficial, sessile, sacciform to cupulate in surface view, collabent when dry, mature conidia collecting in a pearl-white gloeoid mass, subglobose to cylindrical in sectional view, glabrous. Conidiomatal wall 4–7 μm wide, uppermost row of wall cells dark brown, tend to be cylindrical to subcylindrical, somewhat encrusted, bordering the rim of the conidiomata, lower wall cells pale brown, short cylindrical. Conidiogenous cells 3–5 × 3–8 µm, constituting most of the conidiomatal wall, ampulliform with a central or acentral aperture, smooth-walled. Conidia 16–25 × 1–2 μm (
= 20 × 1.5 μm, n = 20), hyaline, fusiform to falcate, with acute apex and narrowly truncate base bearing minute marginal frill, curved, mostly 1-septate, smooth-walled, with single, cellular, unbranched, somewhat attenuated, excentric basal appendage (3 × 5 μm).
Material examined: Cuba, Aspiro, Pinar del Rio, on dried malt agar plate cultures derived from holotype in INIFAT C87/53-1, 9 August 1990, T.R. Nag Raj (DAOM 211931).
