Yalomyces pulcher
Yalomyces pulcher Nag Raj, Coelomycetous Anamorphs with Appendage-bearing Conidia: 988 (1993)
Saprobic on leaves of Litsea sp. Sexual morph: undetermined. Asexual morph: Conidiomata 120–170 µm diam., 120–200 µm high, pycnidial, hypophyllous, solitary, deeply immersed in the host mesophyll with only the ostiole visible in surface view, globose to subglobose, unilocular, glabrous, thick-walled, ostiolate. Ostiole single, circular, centrally located, lined with periphyses in the ostiolar channel. Periphyses hyaline, subcylindrical, branched or unbranched, septate, smooth-walled. Conidiomatal wall 10–30 µm wide, composed of thick-walled, pale brown to hyaline cells of textura angularis in the outer layers, gradually merging with hyaline cells of textura prismatica in the inner layers, but becoming thicker, dark brown to pale brown cells of lenticular textura angularis or textura angularis to textura globulosa around the ostiolar region. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 5–9 × 2–4 μm, arising from the inner wall layer of conidiomata, hyaline, enteroblastic, cylindrical, smooth-walled, with percurrent proliferations above. Conidia 27–63 × 17–24 μm (
= 51 × 22 μm, n = 30), hyaline, elongate-ellipsoid, broadly ellipsoid or obovoid, with rounded ends, straight or slightly curved, dictyoseptate, muriform, smooth-walled, bearing tentaculiform or irregular mucoid appendages.
Material examined: India, Coorg, Somwarpet, on dead leaf of Litsea sp. (Lauraceae), 30 June 1962, T.R. Nag Raj, (DAOM 215257, holotype).
