  • A new species of Mucor (Mucoromycotina, Mucorales) isolated from an enclave of Upland Atlantic Forest in the semi-arid region of Brazil
    Phytotaxa, 2018
    Co-Authors: Carlos A. F. De Souza, Kerstin Voigt, Luciana M. S. Gurgel, Thalline R.l. Cordeiro, Rafael José Vilela De Oliveira, Diogo X. Lima, André Luiz Cabral Monteiro De Azevedo Santiago
    Abstract:

    During a survey of Mucorales in fragments of an Atlantic Upland Forest inserted in the semiarid region of Pernambuco, Brazil, a specimen of Mucor was isolated from soil samples. The specimen was characterized based on morphological, physiological and molecular data (ITS and LSU rDNA regions). The isolate produces intensely branched sporangiophores commonly with between one and several septa with mostly applanate columellae. The sporangiophores were smooth-walled and varied in shape and size, while some were subglobose. The best growth was at 25°C but there was also good growth at 30°C. Based on the evidence of the Analyzed Datasets a new species of Mucor is proposed. A detailed description of the new specimen of Mucor from the Brazilian semi-arid region are provided.

  • DESCRIPTION OF MUCOR PERNAMBUCOENSIS (MUCORALES, MUCOROMYCOTA), A NEW SPECIES ISOLATED FROM THE BRAZILIAN UPLAND RAINFOREST
    Phytotaxa, 2018
    Co-Authors: Catarina Letícia Ferreira De Lima, Carlos A. F. De Souza, Luciana M. S. Gurgel, Rafael José Vilela De Oliveira, Diogo X. Lima, Ingrid B. Cavalcanti, André Luiz Cabral Monteiro De Azevedo Santiago
    Abstract:

    The Mucor genus mostly comprises saprobe specimens which are commonly isolated from herbivore dung, fruit and soil. Morphologically, Mucor specimens produce simple or branched sporangiophores without basal rhizoids and non-apophysate sporangia. During a survey of Mucorales in soil from an upland rainforest area in Pernambuco, Brazil, one specimen of Mucor was isolated and characterized based on morphological, physiological and molecular data (ITS1-5.8S-ITS2 and LSU rDNA sequences). The specimen is characterized by producing strongly sympodially branched sporangiophores and sporangiospores which can contain one or more granules at each end. The columellae are frequently globose or obovoid, some ovoid or cylindrical with a truncate base, rarely piriform.  It grew better at 25oC, with no development at 35oC. Based on the evidence of the Analyzed Datasets, a new species of Mucor is proposed.

  • Description of Backusella constricta sp. nov. (Mucorales, ex Zygomycota) from the Brazilian Atlantic Rainforest, including a key to species of Backusella
    Phytotaxa, 2016
    Co-Authors: Diogo X. Lima, Carlos A. F. De Souza, Kerstin Voigt, Rafael José Vilela De Oliveira, Cristina Maria De Souza-motta, André Luiz Cabral Monteiro De Azevedo Santiago
    Abstract:

    The Backusella genus comprises mucoralean saprobes that inhabit in mainly soil and form transitorily curved (when young, erect at maturity) sporangiophores arising directly from the substratum, with simultaneous production of both sporangia and sporangiola. During a study of Mucorales in soil from an Atlantic Rainforest in Pernambuco, Brazil, one specimen of Backusella was isolated and characterized based on morphological, physiological and molecular data (ITS1-5.8S-ITS2 and LSU rDNA sequences). The phylogenetic analyses of the isolate revealed that it belongs to the Backusellaceae and is closely related to species of Backusella . The specimen grew better at 25oC, with no development at 40oC, and presented conical and cylindrical columellae possessing a central constriction as well as subglobose sporangiospores 7.5–15 × 5.5–10 µm. Based on the evidences of the Analyzed Datasets, a new species of Backusella is proposed and a taxonomic key for the species of this genus is provided.

  • A new species of Lichtheimia (Mucoromycotina, Mucorales) isolated from Brazilian soil
    Mycological Progress, 2013
    Co-Authors: André Luiz Cabral Monteiro De Azevedo Santiago, Rafael José Vilela De Oliveira, Diogo X. Lima, Kerstin Hoffmann, Helder Elísio Evangelista Vieira, Elaine Malosso, Leonor Costa Maia, Gladstone Alves Da Silva
    Abstract:

    During studies on Mucorales in semiarid and littoral dune areas in the northeast of Brazil, two cultures of an Absidia-like species were isolated from soil. They were characterized based on morphological, physiological and molecular data (5.8S and LSU rDNA sequences). The phylogenetic analyses of the isolates revealed that they belong to the Lichtheimiaceae and are closely related to species of Lichtheimia. The two isolates produced simple or branched, erect and circinate sporophores, occasionally with a septum under the sporangia, characteristics also common in Lichtheimia species. However, different from the described Lichtheimia species, the columellae of our isolates were mainly short hemispherical, never spatulate or elliptical and without projections. Sometimes, a long conical or bell shaped apophysis was found. Both isolates grew better at 30–35 °C, with no development at 42 °C, and giant cells were not observed. Based on the evidence of the Analyzed Datasets a new species of Lichtheimia is proposed.
