Conioscypha taiwaniana J.L. Chen & S.S. Tzean, Bot. Bull. Acad. Sin. 41:315-322. 2000.

 Description: Colony diameter on Oat Meal Agar, 30-32 mm in 48 days at 25°C, effuse, velvety, black at the submargin, white at the center and margin; reverse pale yellowish white at the center and margin, dark grey or olive grey at the submargin. Mycelium immersed, composed of branched, septate, smooth, hyaline 1.1-2.8 μm wide hyphae. Conidiophores micronematous, semi-macronematous, mononematous. Conidiogenous cells cuneiform, percurrent, smooth, hyaline, 2.8-6.4 × 4.0-7.2 μm, with a multilayered cup-like collarette up to 25.0 μm wide at the apex. Conidia enteroblastic, 1-celled, smooth, truncate at the base with a central pore, moderately flattened in one plane, in front view: napiform, globose to subglobose or ovoid, black brown or black, 17.0-29.0 × 15.0-24.0 μm, in lateral view: broadly ellipsoidal, up to 12.0-18.0 μm wide, pale brown to brown at the center, dark or black brown at both sides; often with smaller, ellipsoidal, subglobose to globose or obovoid, smooth, yellowish brown to brown secondary conidia, 10.8-19.2 × 5.6-13.4 μm.

 Note: Conioscypha taiwaniana is similar to C. hohnelii, but can be distinglished by the larger, black conidia, the wider multilayered cup-like collarette and secondary conidia. In 1996, Matsushima published a new species of Conioscypha, C. dimorpha Matsushima, which has two kinds of conidia. C. taiwaniana is closely related to C. dimorpha, but C. tai-waniana can be distinguished by the larger conidia and lack of microconidia. Differences between C. taiwaniana and other species of Conioscypha are the shape, size, color and walled-ornamentation of conidia. Pigments which are roughly deposited and present in the walls of the conidia of C. lignicola and C. japonica cannot be observed in conidial walls of C. taiwaniana. C. bambusicola is the only species having more or less ovate conidia which are apically pointed. The conidia of C. varia are smaller, ovoid, flammiform, naviculiform or subellipsoid.
