, solitary, scattered, semi-immersed or superficial, globose, hyaline when young, turning dark brown to black when mature, ostiolate, the ostiole more or less sessile or raised into a very short neck. Peridium 5–8(-12) μm thick, comprising 2–3 layers of radically compressed pseudoparenchymatous cells, cells 10–15 μm diam. in surface view, cell wall 2–3 μm thick. Hamathecium consisting of few, 2.5–4 μm broad cellular pseudoparaphyses, embedded in mucilage, rarely anastomosing and branching, septate, 7–13 μm long between two septa. Asci (65-)80–95 × 20–32.5 μm (\( \barx = 75.6 \times 29.4\mu m \), n = 10), (1-)2(-3)-spored, bitunicate, fissitunicate,

broadly clavate, with a short and small knob-like pedicel which is up to 13 μm long, ocular chamber best seen in immature asci (Fig. 14a, b, c, d and g). Ascospores accumulating

in a subglobose black shiny mass adhering BIX 1294 together outside the ostiole, 55–68 × 25–28 μm (\( \barx = 59 \times 26\mu m \), n = 10), broadly ellipsoid but becoming narrowed towards the poles, muriform with (5-)7 transverse septa, cells with (0-)l(-2) longitudinal septa in each cell, no constriction at the septa, dark brown, the apical cells paler with no www.selleckchem.com/products/SB-202190.html longitudinal septa, verruculose (Fig. 14e and f). Anamorph: none reported. Material examined: NEW ZEALAND, North Island, Wairarapa District, Nutty Farm, isolated from soil, 3 Mar. 1978, Chea Chark Yen & J.E. Sheridan (CBS 107.79, isotype). Notes Morphology Bimuria Mocetinostat molecular weight novae-zelandiae was first isolated from soil of a barley field in New Zealand (Hawksworth et al. 1979). Based on B. novae-zelandiae, the genus is characterized by a very thin peridium, mostly 2-spored and fissitunicate asci as well as the muriform,

dark brown, verrucose ascospores (Hawksworth et al. 1979). Because of its unique morphological characters, the familial placement of this genus has been debatable and it has been placed in Pleosporaceae (Hawksworth et al. 1979), in Phaeosphaeriaceae (Barr 1987b) and in Melanommataceae (Lumbsch and Huhndorf 2007). Morphologically, Bimuria is most comparable with some superficially similar or allied genera, in particular Montagnula (Hawksworth et al. 1979). However, the thick carbonaceous peridium distinguishes Montagnula from that of Bimuria (Hawksworth et al. 1979). In addition, the ascospores of Montagnula are discharged forcibly through the ostiole instead of forming a Farnesyltransferase mass outside of the ostiole as in Bimuria (Hawksworth et al. 1979). Ascomauritiana lignicola V.M. Ranghoo & K.D. Hyde has somewhat similar ascospores in 4-spored asci, but this taxon has unitunicate asci (Ranghoo and Hyde 1999). The morphological characters of Bimuria, such as ascospore release and large, thick-walled ascospores may be an adaptation to its soil-borne habitat (Hawksworth et al. 1979). Phylogenetic study Bimuria novae-zelandiae was found to be closely related to Phaeodothis winteri (Niessl) Aptroot (syn. Didymosphaerella opulenta (De Not.) Checa & M.E.
