Taxonavigation

Ordo: Hypocreales
Familia: Ophiocordycipitaceae
Genus: Ophiocordyceps

Name

Ophiocordyceps tortuosa Hong Yu bis, D.X. Tang & J. Zhao sp. nov. – Wikispecies link – Pensoft Profile

Etymology

Tortuosa = tortuous, the epithet referred to the “tortuous” arrangement of ascospores in the asci.

Diagnosis

The difference between Ophiocordyceps tortuosa and related species is that Ophiocordyceps tortuosa produces lanceolate and obvious separate ascospores, while O. contiispora produces fusiform and no obvious separate ascospores.

Holotype

China, Yunnan Province, Puer City, Simao District. Infected Colobopsis sp. (Formicinae) biting into a leaf of Lauraceae Juss., 22°42'40"N, 100°57'28"E, alt. 1345 m, 03 October 2022, Hong Yu bis (YHH 2210035 – preserved in the Yunnan Herbal Herbarium).

Description

Sexual morph: External mycelia produced from all orifices and sutures, often covering the host body, initially white turning brown. Stromata single to multiple, produced from dorsal pronotum, part branched, 16–24 mm in length, cylindrical, pale white to light brown, becoming pinkish at the apical part. Fertile region of lateral cushions, 1–3, commonly 2 per stroma, hemispherical, chocolate brown at maturity, 1–1.9 × 0.8–1.3 mm. Perithecia immersed to partially erumpent, flask-shaped, (211–) 218–298 (–305) × (94–) 99–142 (–158) μm, with short, exposed neck or ostiole. Asci 8-spored, hyaline, cylindrical, (92–) 96–132 (–134) × 7–11 (–13) μm. Ascus caps slightly prominent, hemispherical, 4–5 × (2–) 3–4 μm. Ascospores hyaline, thin-walled, lanceolate, tortuous arrangement in the ascus, 47–64 × 5–7 μm, 6–7-septate, gently curved at round apex, tapered end shorter than round apex.
Asexual morph: Hirsutella-A type associated with the apical part of stromata. Hirsutella-C type produced from the leg and antennal joints. Phialides lageniform, 54–99 μm long, 4–6 μm width at base, tapering to a long neck, 1–2 μm in width. Conidia fusiform to limoniform, 6–8 × 3–5 μm, slightly narrowing at the top.
Germination process: The released ascospores germinated within 48 h to produce 1–2 long and extremely narrow hair-like capilliconidiophores, (27–) 44–65 (–69) × 1–2 μm, bearing a single terminal capilliconidium, (5–) 6–9 × 3–4 (–5) μm, hyaline, smooth-walled, limoniform to fusiform, slightly narrowing and curved at the top.
Host: Colobopsis sp. (Formicinae).

Habitat

Subtropical monsoon evergreen broad-leaved forest. Infected Colobopsis sp. biting into a leaf of Lauraceae Juss., from 1.2 to 2.4 m above the ground.

Distribution

China, Yunnan Province, Puer City.

Material examined

China, Yunnan, Puer City, Simao District. Infected Colobopsis sp. biting into a leaf of Lauraceae Juss., 22°42'40"N, 100°57'28"E, alt. 1,345 m, 03 October 2022, D.X. Tang (YHH 2210003, YHH 2210004, YHH 2210005, YHH 2210006).

Notes

In the phylogenetic tree, the new species O. tortuosa was sister to O. contiispora (Fig. 1: BS = 100%, BPP = 100%) within O. unilateralis core clade (Fig. 1: BS = 100%, BPP = 100%). Ophiocordyceps tortuosa was distinct from other species of the O. unilateralis core clade in that it produced lanceolate, obvious separate and tortuous arrangement ascospores in the ascus and produced branched stromata, slightly narrowing conidia (Table 3).

Figure 1. Phylogenetic tree of Ophiocordyceps and related genera, based on the concatenation of LSU, SSU, TEF1α, RPB1 and RPB2 sequence data. The tree was generated from an alignment of 4,827 sites and 143 taxa (38 within O. unilateralis). The phylogeny was inferred using the IQ-tree. Values at the nodes represent IQ-tree bootstrap proportions (on the left) and posterior probabilities (on the right). All values were shown at the nodes. The scale bar 0.02 indicates the number of expected mutations per site. The two new species were indicated in blue and red font within O. unilateralis core clade. Two species (T. inflatum OSC 71235 and T. ophioglossoides CBS 100239) in Tolypocladium were used as the outgroup taxa.
