Paracremonium lepidopterorum D.Q. Ming, W.H. Chen, Y.F. Han & Z.Q. Liang sp. nov. ( Fig. 2 ) Mycobank No.: MB 837492

Type:— CHINA. Guizhou Province: Duyun City, Doupeng Mountain (26°21′27.96″N, 107°22′48.22″E), on a pupa, 1 October 2019, Wanhao Chen, holotype GZAC DY1035 ; ex-type culture GZAC DY10351. Sequences from the strain DY10351 have been deposited in GenBank with accession numbers: ITS = MW000352 , LSU = MW000470 , TUB = MW015086 .

Colonies on PDA, attaining a diameter of 23–25 mm after 14 days at 25 °C, white to yellowish, thin, reverse yellowish. Hyphae septate, hyaline, smooth-walled, 1.4–1.5 μm wide. Conidiophores mononematous, hyaline, smooth-walled, with whorls of 2–6 phialides, or penicillium-like from hyphae directly. Phialides 5.4–8.5 × 2.8–3.3 μm, consisting of a cylindrical, somewhat inflated base, tapering to a thin neck. Conidia hyaline, smooth-walled, mostly fusiform, 4.4–5.9 × 2.6–3.0 μm, forming divergent and basipetal chains. Chlamydospores not observed. In culture both phialides and conidia are of similar general shape and size to those found on the pupa.

Etymology:— referring to the fungus colonizing pupa in the order Lepidoptera .
