- Mycotypha indica P.M. Kirk & Benny, in turkey dung, a new record for Venezuela Adolfredo E. Delgado Ávila Lilia M. Urdaneta García Albino J. Piñeiro Chávez Agrociencias Mycotypha turkey dung sporangiola homothallic fertile vesicle On the basis of a study of coprophilous fungi from Zulia state,Venezuela, a Mycotyphaceae(Mucorales) Zygomycota with umbranched sporophores at first, often secondarily branched;more or less erect, up to 3-4mmhigh, 6-8 µm diam; hyaline at first, becoming pale blushgray, non-septate distally below the fertile vesicle. It is variable in length, ovoid to long-cylindricalminutely roughened; without sporangiola, rounded at apex, sporangiola dimorphic andborne in the outer row, are obvoid sporangiospores of similar size and shape to the sporangiola.Substrate hyphae branched, no septate at first, becoming irregularly septate, giving rise to hyaline,globose, yeast-like budding cells, occasional cell segments forming chlamydospores.Zygospores abundant, formed on aerial hyphae near surface of substrate; globose to subglobose,suspensors opposed, anisogamus, smooth, hyaline to pale gray. Homothallic. Colonias onMeye medium of 4-6 cm diam, in 10-12 days at 22-24°C; turf dense, more or less zonate, mousegray color. The species was identified as Mycotypha indica, in turkey dung, which represents anew record from Venezuela. 2007 artículo científico 1317-2255 https://www.redalyc.org/articulo.oa?id=90470208 en http://www.redalyc.org/revista.oa?id=904 Multiciencias application/pdf Universidad del Zulia Multiciencias (República Bolivariana de Venezuela) Num.2 Vol.7
