holotype
GZAC
150317, ex-type culture
GZU
0317bea and dried ex-type culture
GZU
0317bea.1).
Colony growth and appearance similar on full strength Sabouraud’s dextrose and potato dextrose agars,
40–46 mm
in diam. After 14 days at 25 °C, colony non-odorous, white to yellowish white, with aerial mycelium white, dense, velutinous, powdery while sporulating. Reverse light aurantium. Vegetative hyphae septate, branched, hyaline, smooth walled, 1.1–3.2 μm wide. Conidiogenous cells solitary or occurring in lateral clusters, with base subcylindrical or occasionally subspherical, 3.2–5.9 (–10.8) × 0.9–1.1(–1.3) μm, and sympodially branced neck tapering into a long slender denticulate rachis, geniculate or irregularly bent, 6.4–16.2 × 0.5–1.1 μm. Conidia 1.3–4.5 × 0.9–2.5 μm, Q = 1.9–3.2 (
Lm
= 2.7,
Wm
=1.4,
Qm
=1.6), ellipsoidal to globose, hyaline, aseptate, walls smooth and thin.
Etymology
:—
araneola
, referring to its host spider.
Distribution
:—
Guizhou Province
,
China
.
Material examined
:—Dried specimen
GZAC
150317 (
holotype
) and its isolate
GZU
0317bea have been deposited at
Guizhou
University (
GZAC
).
Notes: The new species is similar to four other species in the genus
Beauveria
(
Table 1
),
Beauveria caledoninca
Bissett & Widden
,
Beauveria lii
Sheng L. Zhang & B. Huang
,
Beauveria sinensis
Ming J. Chen, Z.Z. Li & B. Huang
and
Beauveria vermiconia
de Hoog & V. Rao. However
,
Beauveria araneola
can be easily distinguished from these species by its long slender denticulate rachis, subcylindrical conidiogenous cells, and ellipsoidal to globose conidia.
