INTRODUCTION Colonies of a dematiaceous Hyphomycetes was observed growing on the dead branchlets of Morinda citrifolia (Rubiaceae) in Kotabatu near Bogor (West Java). The features of this fungus answer all the diagnostic characters of Endop- hragmiella Sutton (1973), a genus which according to Hughes (1979) should be characterized mainly by its rhexolytically seceding conidia. Its 1-septate, oblong, and brown conidia make this species somewhat resembles Endophragmiella uniseptata (M.B. Ellis) Hughes– –originally classi-fied as Endophragmia uniseptata M.B. Ellis (1959, 1971)–– but that British and New Zealand species has larger conidia masuring 13–27 x 9–12.5 μm with the lower cell sometimes slightly paler. In some respects, it is also similar to Endophragmiella pallescens Sutton except for the fact that that Canadian species has branched conidiophores producing longer conidia measuring 15–24 x 7–8 μm. As implied by its name, the other Canadian species Endo-phragmiella angustispora Hughes (1979) has navicular to ellipsoidal to narrowly ovoid conidia measuring 14.5–20.5 x 4.5–5.5 μm. Endo-phragmiella cambrensis M.B. Ellis (1976) from Wales also has 1-septate and small-sized conidia measuring 13 – 18 x 8 – 10 μm, but those conidia are obovoid or clavate and dark brown coloured. Likewise the 1-septate conidia of the mostly temperate species Endophragmiella globu- losa (Sutton) Hughes, Endophragmiella taxi (M.B. Ellis) Hughes, Endophragmiella pinicola (M.B. Ellis) Hughes, and Endophragmiella boewei (Crane) Hughes (1979) are obovoid or pyriform, so that they are markedly different from the present tropical species. Accordingly, this Javanese collection is made the type specimen of Endophragmiella bogorien- sis Rifai, a new species described below. It clearly belongs to the narrowly envisaged Endophragmiella as this genus is circumscribed by Ellis (1976). It should be noted that in emending the genus by absorbing many species previously accommodated in Endophragmia Duvernoy & Maire by Ellis (1959, 1971, 1976), Hughes (1979) already indicated the possibility of segregating several more managable genera based on the nature of their spore septation. Endophragmiella bogoriensis Rifai, spec. nov. – Fig. 1. Coloniae effusae, brunneae, pilosae. Mycelium immersum vel superficiale, ex hyphis ramosis, septatis, pallide brunneis, levibus compositum. Conidiophora simplicia, recta vel flexuosa, pallide brunnea, laevia, septata, usque ad 200 μm longa, 3–4,5 μm crassa, per proliferationes percurrentes elongascentes. Conidia acrogena, oblonga vel ellipsoidea, brunnea, laevia, 1- septata, 12–18 x 7–9 μm, basic claro protrudenti praedita. REINWARDTIA [VOL.12 276 Fig.1. Conidophores, conidiogenous cells, and conidia of Endophragmiella bogoriensis Rifai (based on type specimen). Habitat in ramolis emortuis Morindae citrifoliae, Kotabatu, prope Bogor, Java, 22 Februarii 2007, M.A.Rifai s.n. (BO typus). Colonies effused, pale brown to brown, distinctly hairy. Mycelium both superficial and immersed in the substratum, composed of branched, septate, pale brown to brown, smooth walled, 2–4 μm thick hyphae. Conidiophores erect, straight or flexuous, simple or very rarely branched, cylindrical, brown, smooth walled, septate, elongate through percurrent proliferations, 60–200 μm long, 3.5–5 μm thick, sometimes swollen up to 6.5 μm at the base. Conidiogenous cells monoblastic and integrated, terminal, generally percurrently elongated, cylindrical but rather abruptly taper to the truncate pale brown apex. Conidia solitary, acrogenous, broadly oblong to ellipsoidal and rounded at the apex, smooth walled, brown, 1 septate, 12–18 μm long and 7–9 μm thick in the broadest part, rhexolytically secede from the conidigeneous cell so that each one is provided with a protuberant thin walled up to 3.5 μm diam. peg.
