Ascospores hyaline, verruculose, cells dimorphic; distal cell (3.8–)4.0–4.8(–5.2) × (3.3–)3.5–4.0(–4.5) μm, l/w (1.0–)1.1–1.3(–1.4) (n = 30), subglobose or ellipsoidal; proximal cell (4.3–)4.5–5.8(–6.6) × (2.8–)3.0–3.5(–4.0)
μm, l/w (1.3–)1.4–1.9(–2.2) (n = 30), oblong or wedge-shaped. Habitat: on wood and bark of Prunus laurocerasus. Distribution: England, known only from the type specimen. Holotype: United Kingdom, England, Leicestershire, on laurel sticks, soc. effete pyrenomycete in bark fissures, Oct. 1881T. Howse (K 137610). Notes: Stromata of Hypocrea splendens in the holotype specimen, said to grow on laurel sticks, are obviously not on selleck screening library Laurus, but on corticated branches of Prunus laurocerasus, which, usually BIBW2992 order planted in dry habitats, is an unusual host for a Hypocrea. The stromata are pulvinate and compact, unlike those of H. auranteffusa, while microscopic traits are indistinguishable in the two species. The anamorph and phylogenetic position of H. splendens are to date unknown. For another description see Petch (1938). Hypocrea strobilina W. Phillips & Plowr., Grevillea 13: 79 (1885).

Ascospores hyaline, verrucose, cells dimorphic; distal cell (4.3–)4.7–5.3(–5.7) × (3.5–)4.0–4.5(–4.8) μm, l/w (1.0–)1.1–1.3(–1.5) (n = 30), (sub)globose; proximal cell (4.8–)5.0–6.8(–8.0) × (2.8–)3.5–4.0(–4.5) μm, l/w (1.2–)1.3–1.9(–2.3) (n = 30), oblong. Among another hyphomycete with brown pyriform, pointed conidia, a scant greenish Trichoderma is present on the holotype.

Habitat: on cones of Pseudotsuga menziesii. Distribution: Europe (United Kingdom), known only from the holotype with certainty. Holotype: United Kingdom, England, Herefordshire, Hereford, Belmont, on cones of Pseudotsuga menziesii, Nov. 1878, J. Renny (ex herb. C.B. Plowright) (K 154040; only half of the cone received/examined). Notes: The stromata of H. strobilina in the holotype are on a cone of Pseudotsuga menziesii (Douglas fir), not Picea abies (‘spruce fir’) as given in the protologue or Abies alba (= A. pectinata) as interpreted by Saccardo (1886). Pseudotsuga menziesii was introduced to Europe by D.
