Unranked: LachnaceaeGenus: Lachnellula
SUMMARY
Anamorph: on 2% MEA with wheat straw, conidiomata formed as yellow stromatic structures with convoluted locules. Conidiophores 15-28 µm long, simple or verticillately branched. Conidia dimorphic, either 2-3 x 1.5-2 µm and cylindric ellipsoidal or ca 4 µm long and 1-1.5 µm diam.
Teleomorph: ascomata apothecia, scattered or grouped, erumpent, short-stalked, initially closed and then ± globose, expanding to form a ± flat disc. Disc ochraceous to orange, surrounded by persistent white hairs. Outer wall composed of globose to polygonal cells, with the central tissue composed of loosely interwoven hyphae. Interascal tissue of unbranched paraphyses, longer than the asci, flexuous, filiform but sometimes rather irregular in shape, often swollen at the apices and then narrowly clavate to moniliform and 4-5(-6) µm diam. Asci 120-150 x 10-12 µm, cylindrical to narrowly cylindric-clavate, apparently lacking croziers, the apex obtuse to rounded with a pore that at least sometimes stains blue in iodine, 8-spored. Ascospores arranged obliquely uniseriately, 16-24 x 7.5-8.5 µm, broadly ellipsoidal to fusiform-ellipsoidal, sometimes with one end fusiform and the other obtusely rounded, hyaline, aseptate, thin-walled, without a gelatinous sheath or appendages.
