Descriptions
Mycelium immersed. Conidiophores originating from brown, smooth, usually swollen cells up to 25 µm wide; macronematous, mononematous, single, unbranched, erect, straight or slightly flexuous, smooth, septate, brown, paler towards the apex, up to 400 µm long x 5-10 µm thick. Conidiogenous cells monophialidic, integrated, terminal, urceolate, pale brown 32-55 µm long x 5-7.5 µm wide; collarette cylindrical or obconical, 3-4 µm wide at base, 4-5 µm at apex. Conidia endogenous, catenate, obtriangular, hyaline, smooth, non-septate, (9.5-) 12-14 (-15) µm long x 4.5-6 (-9) µm wide at the apex, and 2-3 µm at the truncate base, often with a basal marginal frill, distal end bearing 2 setulae each up to 10 µm long x c. 0.25 µm wide.
Mycelium internum. Conidiophora macronematosa, mononematosa, soli¬taria, eramosa, erecta, recta vel paulo flexuosa, laevia, septata, brunnea, apicem versus pallidiora, usque ad 400 µm longa x 5-10 µm crassa; e cellulis brunneis, laevibus, basi plerumque ad 25 µm inflatis. Cellulae conidiogenae monophialidicae, in conidiophoris incorporatae, terminales, urceolatae, pallide brunneae, 32-55 x 5-7.5 µm; collum cylindricum vel obconicum, basi 3-4 µm latum, apice 4-5 µm latum. Conidia endogena, catenulate extrusa, obconica, hyalina, laevia, eseptata, (9.5-) 12-14 (-15) µm longa, apice 4.5-6 (-9) µm lata, basi truncata, 2-3 µm lata, saepe fim¬briam marginalem ferente, apicaliter bisetulosa.

The specific epithet refers to the two setulae on the conidia.
Mycelium internum. Conidiophora macronematosa, mononematosa, solitaria, eramosa, erecta, recta vel paulo flexuosa, laevia, septata, brunnea, apicem versus pallidiora, usque ad 220 µm longa x 5-7 µm crassa; e cellulis fuscis, laevibus, basi saepe ad 25 µm inflata, radialiter lobata. Cellulae conidiogenae monophialidicae, in conidiophoris incorporatae, terminales, urceolatae, pallide brunneae, 30-36 x 5-7 µm; collum obconicum, basi 2.75-3 µm latum, apice 4.5-5.5 µm latum. Conidia endogena, catenulate extrusa, late obconica, hyalina, laevia, eseptata, (8-) 9-10.5 (-11) µm longa, apice (7.5-) 8.5-10.5 µm lata, basi truncata, 1.75-2 µm lata, apicaliter bisetulosa.
