Colletotrichum parallelophorum

Ciri dan struktur

Asexual morph on CMA. Vegetative hyphae 2–4.3 µm diam (N=30), smooth-walled, septate, branched, hyaline to pale brown. Chlamydospores not observed. Conidiomata acervular, orange. Appressoria (56.7–) 60.2–79.2 (–81.2) × (2.8–) 2.9–3.7 (–3.9) µm (N=8), single, sub-globose, brown, rare. Conidiophores and setae formed on a cushion of pale brown cells (1.9–) 2.4–4 (–4.6) µm diam. Setae medium brown, smooth-walled, 2 or 3-septate; base cylindrical, constricted at the base, apex acute. Conidiophores (18.3–) 20.8–34 (–41.2) × (2.6–) 2.8–4.3 (–5.4) µm (N=20), smooth-walled, 2 to 3-septate, branched, hyaline to pale brown. Conidiophores and setae formed on a cushion of pale brown prismatic cells, sometimes with guttules. Conidia (12.1–) 13.8–16.8 (–18.9) × (3.3–) 4.4–7.5 (–7.9) µm (N=50), L/W = 2.6, hyaline, smooth-walled, with 1 to 4 guttules, cylindrical with both ends rounded. Sexual morph on CMA. Ascomata (267–) 261.4–342.3 (–346.2) × (190.4–) 173.0–272.5 (–280) µm (N=3), globose, glabrous, Ascomata isolated, scattered, irregular and asymmetrical, black. Peridium 13.6–46.4 µm thick, consist of pale to medium brown flattened angular cells. Ascogenous hyphae hyaline, smooth-walled. Asci (43.3–) 44.1–63.3 (–66.5) × (7.6–) 8.0–9.8 (–10) µm (N=7), cylindrical, straight, unitunicate, 8–spored. Ascospores (13.9–) 14.1–18 (–20.9) × (3.1–) 3.9–5.4 (–5.8) µm (N=23), L/W = 3.5, uni-to bi-seriately, aseptate, smooth-walled, ellipsoidal, single guttules in the middle, both ends rounded, hyaline. Cultures on CMA flat with entire margin. Growth rate: 0.4cm/d, with 20-days for sporulation. With fluffy, light green and white mycelia.

Habitat dan peran ekologis

Strains MFLUCC 14-0077, MFLUCC 14-0079 and MFLUCC 14-0083 had identical sequence data and they formed a single clade with MFLUCC 14-0082 and MFLUCC 14-0085. They are closely related to Colletotrichum excelsum-altitudum and C. tropicicola. MFLUCC 14-0077, MFLUCC 14-0079, MFLUCC 14-0082, MFLUCC 14-0083 and MFLUCC 14-0085 have similar morphological characteristics. Therefore, the five strains are regarded as the same species. There were totally 103bp and 101bp differences between MFLUCC 14-0083 and C. excelsum-altitudum / C. tropicicola respectively (mainly in GAPDH). Blastn researches with four-gene sequences of five strains presented 99% identity with ITS sequence of C. cordylinicola strain LC0886, 80% identity with GAPDH (GenBank JN050229), 90% identity with ACT (GenBank JN050218) and 93% identity with TUB2 (GenBank JN050246) sequences of C. tropicola strain LC0598 respectively as mentioned above. Conidia size and shape were very similar among MFLUCC 14-0083, C. excelsum-altitudum and C. tropicicola. Appressoria were rare and in strain MFLUCC –14–0083 appressoria were not variable like that in C. excelsum-altitudum and C. tropicicola. Here we introduced strains MFLUCC 14-0077, MFLUCC 14-0079, MFLUCC 14-0082 and MFLUCC 14-0083 and MFLUCC –14–0085 isolated from stems and roots of Dendrobium sp. 1 as Colletotrichum parallelophorum sp.nov.
