Notes: Teleomorphs of H. rogersonii and the rare H. koningii are morphologically indistinguishable, although asci and ascospores are slightly larger in H. rogersonii. Fresh stromata of these two species find more can be distinguished from other species of the clade because of their orange colour, while dry stromata are generally darker and more reddish brown than fresh ones, making a distinction from several other species of the clade difficult

or impossible. Fresh stromata of H. rogersonii are frequently eaten by characteristic insect larvae, probably belonging to the Mycetophagidae, possibly a species of Triphyllus Latr. The pustulate conidiation of T. rogersonii on SNA is similar to the more effuse conidiation on CMD, except for somewhat denser and PLEKHM2 longer conidiophores, and more variable, broadly ampulliform or narrowly lageniform phialides, often originating on an inflated cell. Trichoderma koningii has slightly larger and more oblong conidia, i.e. often with parallel sides. The conidiation of T. koningii on CMD is more distinctly pustulate than in T. rogersonii, colonies on PDA are hairy, with darker, uniformly grey-green, hardly zonate conidiation, becoming green also at 30°C. Certain isolates of T. rogersonii (cf. Samuels et al. 2006a) may form distinctly zonate colonies. The latter difference may also be due to different lighting conditions. See Samuels et al. (2006a) and Jaklitsch et al. (2006b) for distinction from other species of Trichoderma sect. Trichoderma. Hypocrea rufa (Pers. : Fr.) Fr., Summa Veg. Scand., Sectio Post. 383 (1849).
