Cladosporium herbarum species complex Fig. 26. Cladosporium ossifragi (CBS 842.91). Conidiophores and conidia. Scale bar = 10 µm. K. Schubert del. was re-examined and proved to rather agree with the species concept of C. herbarum s. str. The conidia were formed in simple, rarely branched chains, 6–26 × (4–)5.5–8(–9) µm, 0–3-septate, almost smooth or minutely to densely verruculose or verrucose (Schubert 2005). However, since de Vries’ “lectotypification” was incorrect according to the code (ICBN, Art. 9.2, 9.17), a neotype is designated. The delimitation of C. macrocarpum as a morphologically distinct species from C. herbarum has been controversially discussed by several authors (McKemy & Morgan-Jones 1991, Dugan & Robert 1994, Ho et al. 1999). Based on molecular as well morphological studies, it can be shown that C. macrocarpum is a well-defined species distinguishable from C. herbarum s. str. by forming conidiophores with wider nodes, 5–10 µm, wider and more frequently septate conidia [small terminal conidia 4–11 × (3–)4–6 µm versus 4–10 × 3–5(–6) µm in C. herbarum, intercalary conidia 10–17 × (4.5–)5–9 µm versus 6–16 × 4–6 µm in C. herbarum, secondary ramoconidia 14–25(–30) × (5–)6–9(–10) µm versus 12– 25(–35) × (3–)5–7(–9) µm in C. herbarum] and by being connected to Davidiella macrocarpa. On natural substrates the conidiophores are usually somewhat wider than in culture, 4–8(–10) µm wide, and also the conidia can be somewhat wider, sometimes up to 13(–15) µm. Cladosporium graminum, described by Persoon (1822), as well as C. brunneum and C. gracile, introduced by Corda (1837), are older synonyms of C. macrocarpum and, according to the code, would have priority. However, since C. macrocarpum is a well established, currently used name with numerous records in literature, a proposal to conserve the name against these older names is in preparation for formal publication in Taxon. A characteristic difference between ascomata of C. macrocarpum in comparison to those of C. herbarum, are the smaller, globose pseudothecia, asci with longer stalks, prominence of pseudoparaphyses, and rather inconspicuous luminar ascospore inclusions.
