“…As reported for B. navarrensis CBS 139.77 T [12] and B. proliferans strains [36], B. navarrensis IST 508 also forms terminal and intercalary chlamydospores in old cultures, and formation of ascospores was not observed after incubation of this strain in YM, CMA, MEYA and 5% malt extract agar at 25 °C for up to 4 weeks. These growth media were also used to inspect the formation of asci in a mixture of B. navarrensis CBS 139.77 T and IST 508, but no ascospores were detected during 2 weeks of cultivation.…”

“…The diazonium blue B test was negative for the three strains ( and S1). The results presented herein and in previous works show that B. proliferans and B. navarrensis have a high number of variable phenotypes [12, 13, 36], which makes very difficult their differentiation based on phenotypic results. This variability may be due to the reported formation of hyphal clumps [13] that turns difficult the evaluation of some phenotypes.…”

“…The only difference observed between B. navarrensis and B. proliferans strains tested herein was the assimilation of melezitose by B. proliferans PYCC 5116 T , whereas B. navarrensis strains IST 508 and CBS 139.77 T were unable to assimilate this sugar. Nevertheless, assimilation of melezitose was variable in previous studies [6, 12, 13]. Assimilation of nitrogen compounds by B. navarrensis strains CBS 139.77 T and IST 508 or by B. proliferans PYCC 5116 T was positive for cadaverine, l -lysine and ethylamine, and negative for potassium nitrate, creatinine and imidazole.…”

“…As previously described, colonies from B. proliferans and B. navarrensis are white, delicately downy, and surrounded by a margin of submerged hyphae [12, 36]. In this study, colonies from B. navarrensis strains CBS 139.77 T and IST 508, and B. proliferans PYCC 5116 T were compared after 10 days of growth in CMA, YMA, and YM agar media (Fig.…”

“…More recently, six novel species were identified: B. buckinghamii [7], B. meliponae [8], B. bombycis [9], B. persicus [10], and B. baotianmanensis and B. xishuangbannaensis [11]. The species B. navarrensis was isolated by Sesma and Ramirez [12] from white pepper and was delineated based on the phenotypic characteristics of a single strain CBS 139.77. Based on its phenotypic similarities to Blastobotrys proliferans , B. navarrensis CBS 139.77 T was later considered a synonym of B. proliferans [6, 13].…”

The species Blastobotrys navarrensis Sesma and Ramirez was delineated based on the description of the single strain CBS 139.77T. Based on its phenotypic similarities to Blastobotrys proliferans, B. navarrensis CBS 139.77T was later considered a synonym of B. proliferans. In the present study, we isolated the yeast strain IST 508 (=PYCC 8784=CBS 16671) from the soil surrounding an olive tree in Ferreira do Alentejo, Portugal. The phylogenetic analysis of D1/D2 domain and ITS sequences from strain IST 508 indicates that is closely related to B. navarrensis and B. proliferans. Although strain IST 508 differs from B. navarrensis CBS 139.77T by 14 substitutions and 20 indels (6.6 % divergence) in the ITS sequence, no divergence was detected at the level of D1/D2 domain, mitochondrial small subunit rDNA, and cytochrome oxidase II sequences. On the other hand, strains IST 508 and CBS 139.77 differ from B. proliferans NRRL Y-17577T by eight substitutions (1.4 % divergence) in the D1/D2 domain sequence, by 16 substitutions (2.7 % divergence) in the cytochrome oxidase II sequence, and by 16 substitutions (3.7 % divergence) in the mitochondrial small subunit rDNA sequence. Due to the high number of variable phenotypic tests in B. proliferans and B. navarrensis, strains from the two species are difficult to distinguish. Contrasting with what is described for other Blastobotrys species, no differences were detected at the level of micromorphology between the two species. Nevertheless, based on the molecular differences between the two strains, CBS 139.77 and IST 508, and B. proliferans NRRL Y-17577T and their phylogenetic analysis, strains CBS 139.77 and IST 508 are from B. navarrensis and this species should be considered as an independent species and not a later synonym of B. proliferans. We propose an emended description of B. navarrensis.

Blastobotrys, Sporothrix and Trichosporiella: generic delimitation, new species, and a Stephanoascus teleomorph

1985

The morphological and physiological characters of the species of Blastobotrys, and of a number of similar species of Sporothrix, Trichosporiella and Candida were studied. Blastobotrys is defined as having mother cells (primary conidia) which form distinct, secondary conidia. Sporothrix has non-catenulate conidia, or the conidia are catenulate without marked differentiation of conidia of first and second order. Trichosporiella is delimited from Candida by a stronger coherence between hyphal cells, arthroconidia being absent. Four new Blastobotrys species are described, and two unnamed species; two new combinations are proposed in Trichosporiella. Related species in other genera are briefly discussed. A new Stephanoascus teleomorph is described in two strains originally identified as Sp. fungorum. Two diagnostic keys to the described taxa, using either morphological or physiological characters, are given.

A preliminary survey of cycloheximide-resistant airborne fungi in Turin, Italy

Numbers and type of the cycloheximide-resistant part of the aerially transmitted mycoflora of Turin were studied. Samples from three areas characterized by differing human usage were taken in the first week of March. During each sampling, 12 m3 of air were aspirated, using an one-stage volumetric sieve sampler. Fifty-two mesophilic species and eight thermotolerant were isolated. Propagule load varied from 2.92 to 120.31 cfu m-3. The following species appear not to have been reported previously from air samples: Ascotricha bosei, Blastobotrys navarrensis, Cryptendoxyla hypophloia, Chrysosporium an. gymnoascus demonbreunii, Ophiostoma piceae, Penicillium vulpinum, Phialophora mustea, Rhinocladiella pedrosoi, Scopulariopsis croci, S. komngii and Sesquiallium candelabrum. A significant number of potential opportunistic pathogens was isolated.
