Ochronectria thailandica

Ciri dan struktur

Sexual morph: see Li et al. (2016). Asexual morph: saprobic and hyphomycetous. Colonies on the host solitary to gregarious, vegetative mycelium superficial. Conidiophores erect, mononematous, smooth, hyaline, unbranched, 2-septate, 70–89(x̄ = 77, n = 9) µm. Conidiogenous cell elongated, hyaline, holoblastic, apically producing monoblastic conidia, 22–37 (x̄ = 28, n = 9) µm. Conidia hyaline, smooth-walled, aseptate, ellipsoidal to cylindrical rarely ovoid, 4.5–8.5 × 2–3 (x̄ = 6–2.5, n = 40) µm, L/W 2.5. Conidia germinating on MEA within 24 hours. Colonies on MEA reaching 1.4 mm diam. within 6 days in the dark at 25 °C, edge entire, flat or effuse, sparse. After 7 days colonies become white on the front face, and from below, reddish yellow gradually becomes slightly dark when mature.

Habitat dan peran ekologis

Sexual morph: see Li et al. (2016). Asexual morph: saprobic and hyphomycetous. Colonies on the host solitary to gregarious, vegetative mycelium superficial. Conidiophores erect, mononematous, smooth, hyaline, unbranched, 2-septate, 70–89(x̄ = 77, n = 9) µm. Conidiogenous cell elongated, hyaline, holoblastic, apically producing monoblastic conidia, 22–37 (x̄ = 28, n = 9) µm. Conidia hyaline, smooth-walled, aseptate, ellipsoidal to cylindrical rarely ovoid, 4.5–8.5 × 2–3 (x̄ = 6–2.5, n = 40) µm, L/W 2.5. Ochronectria thailandica was introduced by Li et al. (2016) in Chiang Rai Province, Thailand, from unidentified wood in the water. Our collection from Doi Inthanon includes an isolate found on the petiole of a fallen broadleaf species, which is an asexual morph. In the multi-locus phylogenetic analysis, this isolate clusters with the ex-type strain of Ochronectria thailandica (MFLUCC 15-0140) with BYPP of 1 and MLBS of 100% support. Based on base pair comparisons, the ITS region is identical (99%), with two gaps, and the LSU region is also identical (100%), with no gaps. This confirms that our isolate shares the same identity as the type strain of Ochronectria thailandica. As a result, we introduce the asexual morph of O. thailandica here, supported by graphical illustrations and morpho-phylogenetic evidence.
