Distribution: Denmark, known only from the holotype specimen. Holotype : Denmark, selleck products Nordjylland, Tranum Strand, behind the Himmerlandsfondens Kursus- og Feriecenter Tranum Strand, 57°09′04″ N, 09°26′12″ E, elev. 6 m, on dead

standing stems of Juncus effusus, soc. effete immersed pyrenomycete, holomorph, 24 Aug. 2006, H. Voglmayr & W. Jaklitsch, W.J. 2942 (WU 29229, ex-type culture CBS 120926 = C.P.K. 2445). Holotype of Trichoderma junci isolated from WU 29229 and deposited as a dry culture with the holotype of H. junci as WU 29229a. Notes: H. junci is currently the only species of sect. Trichoderma known on Juncus. Stromata resemble sclerotia of basidiomycetes like e.g. Typhula, with ostiolar openings virtually invisible. The conidiation on long

radial conidiophores in green selleck inhibitor pustules is reminiscent of those in T. atroviride. However, T. atroviride and the closely related T. viridescens can be easily distinguished from T. junci by distinctly slower growth and development of conidiation in the latter. T. junci sporulated after more than 1 week on CMD, while conidiation in T. atroviride and the closely related T. viridescens can be noted from 2 days after inoculation. In addition, conidia of T. junci differ by a larger length/width ratio from those of the related species. The holotype of Hypocrea rufa f. sterilis Rifai & J. Webster, England, Norfolk, Holme-next-the-Sea, on culms of Agropyron pungens, 12 Sep. 1962, J. Webster (K(M) 154038), was examined and found to be morphologically indistinguishable Sulfite dehydrogenase from H. junci. Here it is GDC-0973 mw briefly described: Stromata 0.5–1.6 × 0.4–1.3 mm, 0.15–0.6

mm thick (n = 20), pulvinate, solitary or aggregated in small numbers. Ostioles inconspicuous, minute, plane or convex, hyaline. Surface covered with brown hairs when young, later finely velutinous, some rugose. Colour dark red, vinose, dark reddish brown to nearly black, 8E5–8, some with mycelial margin. Asci (76–)80–90(–96) × (4.5–)5.0–5.7(–6.2) μm (n = 30). Ascospores hyaline, finely verruculose to nearly smooth, cells dimorphic; distal cell (3.5–)3.8–4.5(–5.0) × (3.2–)3.3–3.8(–4.2) μm, l/w (1.0–)1.1–1.3 (n = 30), (sub)globose or wedge-shaped; proximal cell (3.8–)4.2–5.5(–6.6) × (2.5–)2.7–3.2(–3.4) μm, l/w (1.2–)1.4–1.9(–2.5) (n = 30), oblong or wedge-shaped. A search at the original collection site was without success due to drought. The ascospore isolate (Rifai and Webster 1966) did not produce an anamorph on MEA, but abundant chlamydospores and a coconut odour. These findings are not in accordance with H. junci. The coconut odour rather suggest species such as H. atroviridis or H. viridescens. Hypocrea koningii Lieckf., Samuels & W. Gams, Can. J. Bot. 76: 1519 (1998).
