Species MB515497 Moreaua scirpi Vánky, C. Vánky, R.G. Shivas & McTaggart 2009   Bibliography: Vánky, K.; Shivas, R.G.; McTaggart, A.R.; Vánky, C.; Arce, W.A., 2009, Mycologia Balcanica 6(3): 99 (more info) Year of publication: 2009 Status of the name: basionym; legitimate MycoBank's opinion: currently used Classification: Fungi, Basidiomycota, Ustilaginomycotina, Ustilaginomycetes, Ustilaginales, Anthracoideaceae, Moreaua Obligate synonym(s): none Morphic status: Teleomorph (anamorph connection(s) unknown or not recorded) Taxonomic synonym(s): Ordered by epithet name none Descriptions: Latin diagnosis Sori ad superficiem organorum floralium internarum massam nigram glomerulorum sporarum formantes, involucris floralibus perfecte abditi. Glomeruli sporarum subglobosi, ovoidei, ellipsoidales vel irregulares, 15-100 × 16-130 µm, atro-olivaceobrunnei, e sporis 2 - usque nonnullis decem firmiter agglutinatis compositi, raro sporae per singulas. Sporae globosae, ellipsoidales, plerumque irregulares, cum lateribus 1 vel pluribus planis, superficie libera convexa, 9-15 × 9,5-18,5(-20) µm, olivaceobrunneae; pariete 1-2,5 µm crasso, in lateribus contactis levi, ad superficiem liberam subtiliter. irregulariter verrucoso. Original description Sori on the surface of inner floral organs (filaments, ovaries), forming a black, agglutinated to granular-powdery mass of spore balls, completely hidden by the floral envelopes. Spore balls subglobose, ovoid, ellipsoidal or irregular, 15-100 × 16-130 µm, dark olivaceous brown, composed of two to a few tens of firmly agglutinated spores, rarely spores single. Spores globose, ellipsoidal, usually irregular with one or several flattened sides, free surface convex, 9-15 × 9.5-18.5(-20) µm, olivaceous brown; wall 1-2.5 µm thick, smooth on the contact sides, finely, irregularly verrucose on the free surface, there often with small, irregular squamae, probably remnants of the sporogenous hyphae. Thecaphora cornuana A.A. Fisch. Waldh. (Fischer v. Waldheim 1877:35), on Scirpus affinis Roth, W Indies, Island of Guadeloupe, is comparable with Moreaua scirpi. According to the original description, T. cornuana differs from M. scirpi in having spore balls that are 40-70 × 50-90 µm, composed of numerous (50 or more?) spores. The spores are angular, 8-14 µm in diam., pale olive-brown, smooth, bright. T. cornuana is likely a Moreaua sp. distinct from M. scirpi.
