Taxonavigation

Genus: Nagrajomyces

Name

Nagrajomyces fusiformis C. L. Hou & L. Zhuo sp. nov. – Wikispecies link – Pensoft Profile

Etymology

The epithet fusiformis refers to fusoid conidia.

Type

China, Yunnan province, Lijiang, Yulong, 26°40'55"N, 99°54'01"E, alt. 2762 m, on dying twigs of Rhododendron vellereum Hutch. ex Tagg., 20 June 2021, coll. C.L. Hou, M.J. Guo, H. Zhou (holotype CAF 800050).

Diagnosis

This new species differs from N. dictyosporus and N. laojunshanensis by fusoid to elongate-fusoid conidia with pointed ends, usually 1-septate and smaller.

Description

Conidiomata solitary, pycnidial, irregularly plurilocular, subepidermal in origin, immersed at first, then becoming erumpent through the periderm of the host, 545–554 μm diameter, 520–546 μm high, peridium dark brown, 47.0–67.5 μm thick. Conidiophores ampulliform, smooth, hyaline, multiguttulate, 12–29 × 2.0–3.5 μm (x̄ = 19 × 3 μm, n = 20). Conidia fusoid to elongate-fusoid, 1-septate, cells equal, smooth, hyaline to pale brown, 13.5–19.0 × 3–4 μm (x̄ = 16.5 × 3.5 μm, n = 20), with a whip‑like appendage at the tip of each conidium, 30–77 μm (x̄ = 51 μm, n = 20) in length (Fig. 4). Sexual morph not observed.

Additional specimen examined

China, Yunnan Province, Lijiang, Laojunshan, 26°37'56"N, 99°43'30"E, alt. 3873 m, on dying twigs of Rhododendron vellereum, 20 June 2021, coll. C.L. Hou, M.J. Guo, H. Zhou (BJTC 1773).

Notes

Nagragomyces fusiformis differs from other species of Nagrajomyces by narrower and 1-septate conidia.
