Notes: Cladosporium pseudocladosporioides (Fig. 1, clade 56) is a common, widespread saprobic hyphomycete phylogenetically and morphologically very close to C. cladosporioides (Fig. 1, clade 66) but clearly distinct by forming a separate lineage in phylogenetic analyses (also see Bensch et al. 2010) and by having shorter and somewhat narrower, 0−1(−2)-septate secondary ramoconidia, narrower conidiogenous loci and hila, and hyphae sometimes forming ropes. However, the distinction between the two species only based on morphology is difficult and not always possible with certainty, which is additionally complicated by the internal genetic structure of the C. pseudocladosporioides clade, suggesting that it possibly represents a complex containing cryptic species (observed in both the act and tef1 alignments in Bensch et al. 2010). Uncertain strains should simply be referred to as C. cladosporioides s. lat. (complex). Cladosporium paracladosporioides (Fig. 1, lineage 13) is also similar but differs in having wider 0−3-septate secondary ramoconidia, wider conidiogenous loci and hila and is phylogenetically distinct (see Bensch et al. 2010).
