Name

Ceratocystiopsis yantaiensis R.L. Chang & X.Y. Zhang sp. nov. – Wikispecies link – Pensoft Profile

Holotype

China. Shandong province: Kunyushan National Forest Park, Yantai city, from the gallery of Cryphalus piceae on Pinus thunbergii, 2 Sep. 2020, R. L. Chang (HMAS249924-holotype; SNM650 = CGMCC3.20247 – ex-holotype culture).

Additional cultures checked

China. Shandong province: Kunyushan National Forest Park, Yantai city, from the gallery of Cryphalus piceae on Pinus thunbergii, 2 Sep. 2020, R. L. Chang (SNM582).

Etymology

The name refers to Yantai City, where this fungus was isolated.

Diagnosis

Ceratocystiopsis yantaiensis differs from closely related species by the production of smaller conidia.

Description

Sexual morph is unknown. Asexual state hyalorhinocladiella-like: the conidiophores directly arising singly from the vegetative hyphae, measuring (2.4–) 4.7–26.7 (–46.4) μm × (0.8–) 1.0–1.5 (–1.8) μm (Fig. 9d, e); or a short basal cell which continues to develop short lateral and terminal extensions from conidiogenous sites at their apices or discrete basal cells that produce 1–5 branches, which then branch irregularly and form conidiogenous cells at their apices, measuring (12.2–) 6.2–10.2 (–50.7) μm long (Fig. 9b, c); conidiogenous cells measuring (4.7–) 6.2–10.2 (–12.4) × (0.7–) 0.9–1.3(–1.5) μm (Fig. 9b, c); conidia hyaline, smooth, unicellular, short oblong, with rounded ends, measuring (1.1–) 1.4–2.2 (–2.7) × (0.8–) 0.9–1.2 (–1.5) μm (Fig. 9b-e).

Culture characteristics

The Colonies are light brown in color on MEA (Fig. 9a). Mycelia are white, superficially growing on the agar. The optimal temperature for growth was 30–35 °C, reaching 43.0 mm diam in 10 days. No growth was observed at 5 °C.

Distribution

Currently known from Yantai City in Shandong Province, China.

Note

Ceratocystiopsis yantaiensis is phylogenetically close to C. manitobensis, but formed a distinct clade on both ITS, LSU, and BT trees (Figs 1 and 2). Two types of hyalorhinocladiella-like asexual state were also observed in C. manitobensis (Hausner et al. 2003[1]). Conidia of C. yantaiensis and C. manitobensis are similar in morphology, but there is a difference in size (1.1–2.7 × 0.8–1.5 vs. 3.0–5.5 × 1.0–2.0 µm, Fig. 9b-e).
