Culture characteristics. Colonies concentric circular pattern with radial furrows, entire, whitish, grey to olivaceous, with black conidiomata clustered in circular distribution; reverse concentric circular pattern with radial furrows, beige around centre and olivaceous at edge.
description
Description. Developing on the fruiting body of Ophiocordyceps macroacicularis. Sexual morph not observed. Asexual morph: Conidiomata pycnidial, semi- or entirely immersed in the agar, solitary or aggregated, erumpent, globose, dark brown to black. Conidiomatal wall of textura angularis, 3 - 5 layered, composed of brown to dark brown, flattened polygonal cells. Conidiophores reduced to conidiogenous cells. Conidiogenous cells phialidic, hyaline, smooth-walled, ampulliform to globose, 3 - 5 x 0.5 - 2 μm, x ¯ + / - SD = 4 + / - 0.7 x 1.5 + / - 0.3 μm. Conidia hyaline, smooth-walled, thin-walled, cylindrical, guttulate, 4 - 6 x 1 - 2 μm, x ¯ + / - SD = 5.3 + / - 0.27 x 1.5 + / - 0.08 μm. Chlamydospores not observed in culture.
diagnosis
Diagnosis. Phylogeny based on ITS, LSU, rpb 2, SSU, tef 1 and tub 2 revealed that the strains NTUCC 17 - 005 and NTUCC 17 - 006 considered in the present study formed a separate lineage sister to the familial clades of Shiraiaceae and Phaeosphaeriaceae in suborder Pleosporineae. Therefore, a new genus Tzeanania, a new species T. taiwanensis and a new family Tzeananiaceae in suborder Pleosporineae, Pleosporales are proposed here for the pycnidial coelomycete growing on the surface of the fruiting body of Ophiocordyceps macroacicularis.
