One of the MP trees obtained based on phylogenetic analysis of ITS sequence data of Aspergillus section Sparsi. Numbers above branches are bootstrap values. Only values above 70 % are indicated. clade includes A. panamensis, A. anthodesmis, A. conjunctus, and the recently described A. amazonicus, A. quitensis and A. ecuadorensis isolates on the trees based on b-tubulin and ITS sequence data (Figs 2, 3; Mares et al. 2008). Although Mares et al. (2008) found that these three isolates have identical ITS sequences, they were suggested to represent distinct species based on morphological data (length of talks, diameter of vesicles, morphology of conidia and number of phialides), and were placed in Aspergillus section Wentii. However, these three isolates could not be distinguished from each other based on molecular, morphological or extrolite data in our study, and clearly belong to section Sparsi (Figs 1–4). Aspergillus amazonicus is chosen as the correct name for the taxon and A. quitensis and A. ecuadorensis are considered synonyms. Aspergillus implicatus, a white-spored species originally assigned to Aspergillus section Candidi (Maggi & Persiani 1994), also belongs to this section. This species was described to produce conidiophores surrounded by sterile hyphae, not yet seen in any other species of the Aspergillus genus. Unfortunately the ex-type culture showed only poor sporulation and only a few conidiophores with sterile outgrowth could be observed (Fig. 5). Phylogenetic analysis of sequence data indicated that the four examined A. sparsus isolates fall into two closely related clades. The three phylogenies were concordant, with no conflict between the topologies of the gene trees, in accordance with the phylogenetic species recognition concept detailed by Taylor et al. (2000). The ex-type strain of A. sparsus (CBS 139.61 T ) together with an isolate from Texas, USA form one clade, while two isolates came from soil from Haiti form another clade on all trees (Figs 1–3). Both of the latter isolates were found by Raper & Fennell (1965) to differ from the ex-type strain of A. sparsus in producing more restrictedly growing colonies in shades of reddish brown on MEA plates, while one of the isolates (CBS 464.91 = NRRL 4569) also produced “small fragmentary sporulating structures adjacent to the agar surface that bear conidia similar to those of normal heads” (Raper & Fennell 1965). Here we describe this new species as Aspergillus haitiensis. Regarding the value of the different loci for species delimitation in section Sparsi, all species could be distinguished using either ITS, b-tubulin or calmodulin sequence data. However, the resolving power was much higher for the protein coding genes than for the ITS region. The situation is more difficult in other sections of Aspergilli, including for example sections Nigri (Samson et al. 2007), Clavati (Varga et al. 2007), and Cervini (J. Varga, unpubl. observ.), where the ITS region cannot be used reliably to distinguish all species assigned to the given section. Extrolite profiles Among the species assigned to Aspergillus section Sparsi, A. panamensis produces cyclogregatin and gregatins (also called graminins or aspertetronins; Anke et al. 1980a, b, 190 i m a f U N G U S
