Groveolopsis pandani

Groveolopsis pandani (Höhn.) Boedijn, Sydowia 5(3-6): 225 (1951)

Facesoffungi number: FoF 07413

 

Parasitic on living leaves of Pandanus sp. (Pandanaceae). Sexual morph: undetermined. Asexual morph: Conidiomata 130160 µm diam., 100140 µm high, black, pycnidioid, solitary to gregarious or confluent, immersed, globose or oval to irregular, unilocular, thick-walled, glabrous, with a dark brown papillate ostiole. Ostiole short, single, circular to oval, centrally located. Conidiomatal wall 830 µm wide, composed of thick-walled, brown cells of textura globulosa at the outer layers, and thick-walled, hyaline cells of textura prismatica at inner layers. Conidiophores reduced to conidiogenous cells. Conidiogenous cells 615 × 38 µm, hyaline, enteroblastic, phialidic, ampulliform to subcylindrical, smooth, arising from the inner wall layers of conidiomata. Conidia 36–55.4 × 59 µm ( = 44 × 6.7 µm; n = 30), hyaline, obclavate, narrow and truncate at the base, attenuated towards the apex, usually asepatte, occasionally 1-septate, smooth-walled, guttulate, bearing a cup-like or irregular, mucoid, apical appendage; basal appendages present or absent.

 

Material examined: Thailand, Chiang Mai, on living leaves of Pandanus sp. (Pandanaceae), 4 February 2012, N. Tangthirasunun, NTP008–1 (MFLU13-0309).
