asperellum (Samuels et al. 2010), T. gamsii

(Jaklitsch et al. 2006b), and T. koningiopsis (Samuels et al. 2006a) are beyond the scope of this work. The notes after each species description help to distinguish some species. Most species of this section require culturing. Microscopic examination of conidia of anamorphs that are associated with stromata in nature may sometimes be useful for identification, e.g. globose and coarsely warted conidia in T. viride, subglobose to ellipsoidal and verruculose in T. viridescens, both often forming yellow mycelium, but most species have smooth conidia, i.e. resembling those of other sections. The safest way in species identification within Hypocrea/Trichoderma section Trichoderma is sequencing of ITS and tef1 introns.

Scale bars: a–d = 20 mm. e = 1.1 mm. f = 0.5 mm. g, n = 40 μm. h = 20 μm. i, l, o = 10 μm. j, k, m, p = 5 μm Stromata Rucaparib when fresh 0.7–2.5 mm diam, 0.3–1 mm thick, solitary to aggregated in small groups, pulvinate, smooth; ostiolar dots invisible or indistinct; perithecia entirely immersed. Colour typically orange-red to brick-red, 6A6–7, 7A5–6, 8AB5–6. Spore deposits white. Stromata when dry (0.5–)0.7–1.6(–2.3) × (0.4–)0.6–1.3(–1.8) mm, 0.3–0.6(–0.9) mm thick (n = 30); pulvinate to semiglobose, broadly (on bark or wood) or narrowly (on ostioles of a fungal host) attached; margin free. Outline circular or oblong. Surface smooth or tubercular, with yellow, rust or light brown hyphae when young. Ostiolar dots (23–)30–46(–63) μm (n = 30) diam, only visible after moistening the surface with water, hyaline, plane or convex.
