Sporothrix cryptarchum

Ciri dan struktur

Sexual and asexual structures produced on the sterilised oak twigs and on the surface of malt agar in Petri dishes. Ascomata abundant, superficially or partly embedded in the agar, single or in groups; ascomatal bases black, globose, (55–)115–172(–210) μm diam., with brown hyphal hairs, 15 to 141 μm long and 0.9 to 3.8 μm wide at the base; ascomatal necks black, straight or curved, (126–)198–412(–544) μm long, diameter (10.9–)13–19(–23.8) μm at the apex and (17.6–)29.3–47.6(–59.6) μm at the base. Ostiolar hyphae present, pale brown, with small granules, septate, straight or curved, simple or dichotomous branching, tips tapering or sometimes thickened, (9–)13–24(–31) in number, (15.8–)30.5–51.8(–60.9) μm long, (0.2–)0.3–0.5(–0.7) μm at the apex and (0.9–)1.6–2.4–(3) μm at the base. Asci subglobose to ovoid, (5.5–)6.7–9(–11) × (4–)4.9–6.2(–7.2) μm. Ascospores one-celled, kidney-shaped to almost triangular in side view in side view (3.2–)3.8–4.7(–5.8) × (0.8–)1–1.3(–1.5) μm, elliptical in front view (3.1–)3.6–4.4(–5) × (1–)1.2–1.6(–1.8) μm, sometimes with residual sheath up to 0.6 μm thick, accumulated in white-colored mass at the tip of the neck. Conidiophores hyaline, micronematous, simple or occasionally branched and bearing several conidiogenous cells, either borne on vegetative hyphae or on upright hyphae. Conidiogenous cells blastic, cylindrical, terminal, lateral or intercalary, straight or curved, tapering towards the apex, swollen apical part forming conidia by sympodial proliferation on narrow denticles, (2.2–)13.9–51.2(–102.8) μm long, (0.7–)1.2–1.8(–2.2) μm wide at the base.

Habitat dan peran ekologis

This species is phylogenetically distinct from the other Sporothrix species based on the ITS, βT, CAL and TEF1-α sequences. Sporothrix cryptarchum is phylogenetically closely related to S. undulata (Sporothrix sp. 12) described in the present study. This species also shares morphological similarities such as kidney-shaped ascospores and two morphological forms of conidia with S. undulata. However, S. cryptarchum has narrow ascospores (0.8–1.5 µm) compared to S. undulata (1.1–2 µm). It also has distinct ostiolar hyphae, with those in S. cryptarchum often dichotomously branching while in S. undulata these hyphae occur only sporadically and do not have dichotomous branching. Both species produce hyaline and pigmented conidia. However, S. cryptarchum cultures are predominantly hyaline whereas those in pure cultures of S. undulata are mostly pigmented. Their conidial shapes in these two species are similar but their dimensions are distinct. Sporothrix cryptarchum has conidia that are smaller than those of S. undulata. In addition, cultures of S. cryptarchum are white and grow in a circular pattern with smooth margins while those of S. undulata grow in a circular pattern with undulate margins and some have grey pigmentation.
