Fungal Diversity as a synonym of A. stellata (Hawksworth 1981). More taxa were subsequently added (Barr 1990a; Hawksworth and Boise 1985; Hyde and Fröhlich 1998), and the generic concept extended to include three elements: 1. typical semiimmersed to superficial ascomata with flattened base, cylindro-clavate asci with fusoid ascospores and trabeculate pseudoparaphyses, i.e. Astrosphaeriella sensu stricto (e.g. A. fusispora and A. vesuvius (Berk. & Broome) D. Hawksw. & Boise); 2. Trematosphaeria-like with rounded ascomata (e. g. A. africana D. Hawksw.); and 3. Massarina-like species with immersed ascomata (e.g. A. bakeriana (Sacc.) K.D. Hyde & J. Fröhl.) (Chen and Hsieh 2004; Tanaka and Harada 2005a; b). Currently, a broad generic concept of Astrosphaeriella is accepted, and 47 taxa are included in Astrosphaeriella. Phylogenetic study Phylogenetic analysis based on LSU and SSU nurDNA sequence data indicates that Astrosphaeriella is polyphyletic, and located in the basal region of the <strong>Pleosporales</strong> between Testudinaceae and Zopfiaceae/Delitschiaceae (Tanaka et al. 2009), or basal to Aigialaceae (Schoch et al. 2009). The genus is, however, clearly not related to Trematosphaeria as previously understood (Boise 1985). Concluding remarks Astrosphaeriella is currently polyphyletic and new collections of the different elements listed above are needed in order to understand the placement of various species. We suggest that some immersed bambusicolous species may belong in Tetraplospheariaceae. Asymmetricospora J. Fröhl. & K.D. Hyde, Sydowia 50: 183 (1998). (?Melanommataceae) Generic description Habitat terrestrial, saprobic. Ascomata solitary or in small groups, immersed, black, lenticular in section, uni- or often multi-locular, with a central ostiole without tissue differentiation. Upper peridium carbonaceous, thicker at sides and apex. Lower peridium composed of irregular-shaped, hyaline cells. Hamathecium of trabeculate pseudoparaphyses, branching and anastomosing between and above asci, embedded in mucilage. Asci 8-spored, bitunicate, fissitunicate unknown, clavate, short pedicellate. Ascospores 1-septate, hyaline, constricted at the septum, with a broad, spreading mucilaginous sheath. Anamorphs reported for genus: none. Literature: Fröhlich and Hyde 1998. Type species Asymmetricospora calamicola J. Fröhl. & K.D. Hyde, Sydowia 50: 184 (1998). (Fig. 9) Ascomata 675–950 μm high×875–1500 μm diam., solitary or in small groups of 2–10, immersed and forming slightly protruding domes on the substrate surface, with nearwhite rim around the central ostiole; in vertical view lenticular, multi- or rarely unilocular, individual locules 175–270 μm high×320–400 μm diam., with a flattened base, ostiole a central opening without tissue differentiation (Fig. 9a). Upper peridium 32–70 μm wide, carbonaceous, composed of a few layers of black walled cells of textura angularis. Lower peridium thinner, composed of hyaline cells of textura globulosa or textura prismatica (Fig. 9b). Hamathecium of long trabeculate pseudoparaphyses, 1.2–1.6(−2) μm wide, branching and anastomosing between and above asci, embedded in mucilage. Asci 137.5–207.5×26–35 μm (x ¼ 172:8 31:5mm, n=20), 8-spored, bitunicate, fissitunicate dehiscence not observed, clavate, with short pedicel (to 25 μm), with ocular chambers (ca. 3μm wide×4 μm high) (Fig. 9c and d). Ascospores 35–55×10.5–15 μm (x ¼ 44:7 12:4mm, n=50), biseriate, navicular to obovoid, hyaline, becoming pale brown when senescent, straight or usually curved, smooth, asymmetric, 1-septate, the upper cell larger with a rounded end, basal cell with a tapering end, constricted at the septum, with spreading mucilaginous sheath (Fig. 9e, f and g) (data from Fröhlich and Hyde 1998). Anamorph: none reported. Material examined: AUSTRALIA, North Queensland, Palmerston, Palmerston National Park, on dead rattan of Calamus caryotoides A.Cunn. ex Mart., Mar. 1994, J. Fröhlich (HKU(M) 7794, holotype). Notes Morphology Asymmetricospora was introduced as a monotypic genus represented by A. calamicola based on its “absence of a subiculum, the absence of short dark setae around the papilla and its asymmetric ascospores” (Fröhlich and Hyde 1998). Because of the immersed ascomata, ostiole and peridium morphology, fissitunicate asci and trabeculate pseudoparaphyses, Asymmetricospora was assigned to Melanommataceae (sensu Barr 1990a; Fröhlich and Hyde 1998). Morphologically Asymmetricospora can be distinguished from its most comparable genus, Astrosphaeriella, by its ostiole, which is a simple opening without tissue differentiation, asymmetric ascospores, and the usually multiloculate fruiting body (Fröhlich and Hyde 1998). Phylogenetic study None. Concluding remarks The placement of Asymmetricospora under Melanommataceae remains to be confirmed.
