Description

Conidiophores 200-350 μm long (x̅ = 280.6 μm, SD = 45, n = 20), 7-10 µm wide (x̅ = 8.6 μm, SD = 1.9, n = 20), mononematous, erect, simple, straight or flexuous, thick-walled, dark brown, paler towards the apex, 8-10 septate. Conidiogenous cells 48.5-60 μm long (x̅ = 53.5 μm, SD = 3.9, n = 20), 9-12 µm wide (x̅ = 10.2 μm, SD = 1.3, n = 20), with a narrow cytoplasmic channel and marked periclinal thickening in the upper quarter, lacking a collarette, proliferating enteroblastically to produce successive conidia at the same level. Conidia 21.5-40 μm long (x̅ = 29.3 μm, SD = 6.8, n = 20), 7.5-10 µm wide (x̅ = 8.2 μm, SD = 0.5, n = 20), holoblastic, solitary, accumulating in translucent slimy masses at the apices of conidiogenous, cylindrical, obtuse at the apex, slightly tapered towards the truncate base, hyaline, 3-euseptate, smooth, eguttulate.

Notes

Kylindria excentrica was firstly found on rotten wood in Ethiopia ( Bhat and Sutton 1985). Kylindria excentrica is similar to K. millettiae Y.D. Zhang & X.G. Zhang in morphology, but differs markedly in conidial dimensions (19.5-24 × 6.5-9 μm vs. 27.5-35 × 7.5-8.5 μm) ( Zhang et al. 2010). In addition, K. excentrica has a lateral flat scar in the conidial base, whereas those of K. millettiae have a lateral flat scar in the excentric ( Zhang et al. 2010).
