ABSTRACT

Here, Quambalaria fabacearum and Neopestalotiopsis brasiliensis are introduced as new species from Brazil, isolated as endophyte from Mimosa tenuiflora and causing post-harvest rot disease on fruits of Psidium guajava, respectively. Diaporthe inconspicua is emended to include a more detailed morphological description. Neopestalotiopsis egyptiaca is reported as new to the Americas and as causing post-harvest rot disease on fruits of Psidium guajava, while Umbelopsis isabellina is reported as endophyte.

Etymology: The name refers to the host plant family, Fabaceae.

Description: Mycelium superficial to partially immersed; hyphae hyaline, smooth, branched, loosely septate, 1.5-2.5 µm wide. Conidiophores similar to hyphae, scattered, cylindrical, terminal or as short side branches, hyaline, smooth, 0-2-septate, rarely 3-septate, (12-) 14-58 (-106) × 1.5-2.5 µm (n=20). Conidiogenous cells cylindrical, terminal or integrated, (5.5-) 9.5-13 (-34) × 1-2 µm (n=20), straight to curved, forming conidia by sympodial growth consisting of a slightly swollen cluster of small conidium bearing denticles; conidiogenous loci denticulate, inconspicuous, pointed or flattened. Conidia hyaline, non-septate, smooth, occasionally guttulate; primary conidia ellipsoidal to fusoid or obovoid, 7.5-8.5 × 1.5-2.5 µm (n=30), with basal scar or scars at both ends, often giving rise to one or several obovoid or narrowly ellipsoidal secondary conidia, (3.5-) 4.5-5.5 (-6.5) × 1.5-2 µm (n=30). Chlamydospores rarely observed. Sexual morph not observed.

Cultures (in the dark, 25 oC, 2 wk): Colonies on PDA growing up to 25 mm diam., finely floccose, zonate, surface white with slightly yellowish color in the middle, reverse yellowish to sienna, with a yellowish ring at the end of the colonies, without any odor; yellow pigment produced in culture medium and a slightly brownish pigment surrounding the culture. After 30 d, colonies are slightly cream-coloured on the surface, reverse dark brown, and a sienna-rust pigment is produced in the medium. Colonies on MEA growing up to 25 mm diam., finely floccose, zonate, surface white and slightly cream-coloured, yellowish in the middle, reverse yellowish brown, without any odour.

Type: BRAZIL. Paraíba: Santa Teresinha, Tamanduá farm (7°1.524’S 37°23.518’W), isolated as endophyte from branches of Mimosa tenuiflora(Willd.) Poir. (Fabaceae), May 2013, J.D.P. Bezerra (Holotype URM 90895; Culture ex-type URM 7756).

GenBank accession numbers: URM 7756 (ex-type): ITS MG253664, LSU MG253665.

Notes - Based on the phylogenetic analyses, the new species, Quambalaria fabacearum, is closely related to Q. cyanescens (Fig. 2). Morphologically, Q. fabacearum differs from Q. cyanescens mainly in the size of the conidiogenous cells ((5.5-) 9.5-13 (-34) × 1-2 µm in Q. fabacearum vs. 30-40 × 1.5-3 in Q. cyanescens), primary conidia (7.5-8.5 × 1.5-2.5 µm in Q. fabacearum vs. 3.5-6.5 (-25) × 2.5-3.5 in Q. cyanescens), secondary conidia ((3.5-) 4.5-5.5 (-6.5) × 1.5-2 µm in Q. fabacearum vs. 2.5-3.5 × 2-2.5 in Q. cyanescens), and in the presence of chlamydospores in Q. fabacearum. Furthermore, these species differ in culture characteristics with the production of a pale yellowish pigment by Q. fabacearum when cultured on PDA, and a purple pigment produced by Q. cyanescens (Hoog & Vries 1973; Paap et al. 2008). The genus Quambalaria was proposed by Simpson (2000) to accommodate species pathogenic to Eucalyptus previously circumscribed as Ramularia and Sporothrix. Later, de Beer et al. (2006) proposed a new family, Quambalariaceae, to accommodate Quambalaria, which was placed in a monophyletic clade in the Microstromatales. Six species of Quambalaria are presently listed in Index Fungorum and MycoBank, being chiefly associated with leaf and shoot diseases of Myrtaceae (Eucalyptus and Corymbia) (Hoog & Vries 1973; Simpson 2000; Beer et al. 2006; Paap et al. 2008; Cheewangkoon et al. 2009). Quambalaria pusilla is the only species without DNA data available (Beer et al. 2006), but it differs morphologically from Q. fabacearum mainly in the size of the conidiophores (5-25 × 1-2 µm), and primary (4-10 × 1-2 µm) and secondary conidia (1.5-3.5 × 0.5-1.5 µm) (Braun 1998). Besides species of Quambalaria being reported as pathogenic to plants, Q. cyanescens is the only species thus far to be associated with human infections, although they are believed to be opportunistic infections, or as a environmental contaminant (Hoog & Vries 1973; Fan et al. 2014). Quambalaria fabacearum is reported here as endophyte, representing the first record from Fabaceae.

Conidiophores hyaline, 0-2-septate, cylindrical, smooth, straight to sinuous, occurring in dense clusters, sometimes branched, 11-21.5 × 2-2.5 µm. Conidiogenous cells phialidic, cylindrical, terminal, (2-)5.5-8.5(-14.5) × (1.5-)2-2.5 µm. Paraphyses not observed.

Notes - Diaporthe inconspicua was proposed by Gomes et al. (2013) for some sterile endophytic isolates from medicinal plants Maytenus ilicifolia and Spondias mombin in Brazil, based on phylogenetic analyses of five genes. Gomes et al. (2013 did not include a morphological description because the ex-type strain and other isolates were sterile in culture media. Based on current phylogenetic inferences using three genes, some endophytes isolated from Poincianella pyramidalis growing in a tropical dry forest (Caatinga) in Brazil demonstrated high identity and phylogenetic relationship (Fig. 4) with D. inconspicua ex-type strain (CBS 133813). Some of these isolates from P. pyramidalis sporulated in culture media, and here is presented a morphological description for D. inconspicua. Diaporthe inconspicua is phylogenetically related to D. pterocarpi, but differs in size of pycnidia (100-120 μm diam.), conidiophores (10-15 × 1-2 μm), and alpha conidia (6-7 × 2.5 μm), and by the absence of beta conidia (Udayanga et al. 2012). Also, the host plants of D. pterocarpi are known to be species of Aloe, Jatropha, Ougeinia and Pterocarpus (Udayanga et al. 2012), while D. inconspicua has been related to an endophyte from species of Maytenus and Spondias (Gomes et al. (2013), and Poincianella, as reported here for the first time.

Etymology: the name “brasiliensis” refers to Brazil, the country where the fungus was collected.

Description: Conidiomata sporodochial on PDA, globose, solitary or aggregated, semi-immersed, black, exuding globose dark brown to black conidial masses. Conidiophores and conidiogenous cells not observed in vitro. Conidia fusoid, ellipsoid, straight to slightly curved, 4-septate, 20-26.5 × 5-8.5 μm; basal cell conic to obconic, hyaline, smooth and thin-walled, 3-5 μm long; three median cells doliiform, 13-16.5 μm long, smooth, concolourous or versicolourous, brown, septa darker than the rest of the cell (second cell from base pale brown, 4-6 μm long; third cell darker brown, 4-5.5 μm long; fourth cell brown, 4-6 μm long); apical cell 3-5 μm long, hyaline, cylindrical to subcylindrical, thin- and smooth-walled; with 1-3 tubular apical appendages, arising from the apical crest, unbranched, filiform, flexuous 8.5-15 μm long; basal appendage single, tubular, unbranched, centric, 2-5 μm long. Sexual morph not observed.

Cultures (under a 12-h photoperiod, 25 °C, 1 wk): colonies on PDA attaining 73 mm diam, with undulate edge, whitish, with dense aerial mycelium on the central surface and dark brown to black conidial masses. Colonies on MEA attaining 68 mm diam, with undulate edge, whitish, with dense aerial mycelium on the central surface and dark brown to black conidial masses.

Pathogenicity test: causing post-harvest rot disease, seven days after the inoculation of healthy ripe guava fruits.

Type: BRAZIL. Minas Gerais: Viçosa, on fruits of Psidium guajava L. (Myrtaceae), February 2014, V.P. Abreu (Holotype VIC44200; Culture ex-type COAD 2166).

GenBank accession numbers: COAD 2166 (ex-type): ITS MG686469, TUB2 MG692400, tef1-α MG692402.

Notes: A phylogenetic tree was generated based on reference/type sequences of the 31 Neopestalotiopsis spp. described to date (Maharachchikumbura et al. 2014; Crous et al. 2015; Ayoubi & Soleimani 2016; Hyde et al. 2016; Jayawardena et al. 2016; Silvério et al. 2016; Akinsanmi et al. 2017). Based on phylogenetic analysis, Neopestalotiopsis brasiliensis is closely related to N. chrysea, N. umbrinospora, N. asiatica and N. macadamiae (Fig. 6). Morphologically, N. brasiliensis differs from N. chrysea, N. umbrinospora, N. asiatica (Maharachchikumbura et al. 2014) and N. macadamiae (Akinsanmi et al. 2017) by having shorter apical appendages (8.5-15 μm) and a shorter basal appendage (2-5 μm). The number of apical appendages for N. brasiliensis and N. umbrinospora range 1-3, which is slightly fewer than other species of the genus. Neopestalotiopsis brasiliensis has larger conidia (20-26.5 × 5-8.5 μm) than N. chrysea, N. umbrinospora, N. asiatica and N. macadamiae. In addition, N. brasiliensis possesses versicolourous or concolourous median cells.

Description (COAD 2167): Conidiomata sporodochial on PDA, globose, solitary, semi-immersed, black, exuding globose, dark brown to black conidial masses. Conidiophores indistinct, reduced to conidiogenous cells. Conidiogenous cells discrete, cylindrical, hyaline, smooth, proliferating 2 times percurrently at apex, 6-11 × 2-3 μm. Conidia fusoid, ellipsoid, smooth, straight and sometimes slightly curved, 4-septate, 21.5-28 × 5-7 μm; basal cell conic, hyaline, smooth and thin-walled, 3-5.5 μm long; three median cells doliiform, 13.5-17 μm long, versicolourous, brown, septa darker than the rest of the cell (second cell from the base 4-6.5 μm; third cell 4-6 μm; fourth cell 4-6 μm); apical cell 3.5-6 μm long, hyaline, cylindrical to subcylindrical, thin- and smooth-walled; with 1-3 tubular apical appendages, arising from the apical crest, unbranched, filiform, flexuous 11-21 μm long; basal appendage single, tubular, unbranched, centric, 1.5-5.5 μm long. Sexual morph not observed.

Cultures (under a 12-h photoperiod, 25 °C, one week): Colonies on PDA attaining 78 mm diam after seven days at 25 °C, with undulate edge, whitish, with dense aerial mycelium on the surface and dark brown to black conidial masses. Colonies on MEA attaining 68 mm diam after seven days at 25 °C, with undulate edge, whitish, with dense aerial mycelium on the surface and dark brown to black conidial masses.

Pathogenicity test: Causing post-harvest rot disease, seven days after the inoculation of health ripe guava fruits.

Material examined: Neopestalotiopsis egyptiaca. BRAZIL. Minas Gerais: Viçosa, on fruits of Psidium guajava L. (Myrtaceae), February 2014, V.P. Abreu (VIC 44201; COAD 2167).

GenBank accession numbers: COAD 2167: ITS MG686470, TUB2 MG692401, tef1-α MG692403.

Notes: Based on phylogenetic analyses, the isolate COAD 2167 grouped in a well-supported clade including the Neopestalotiopsis egyptiaca ex-type strain CBS 140162 (Fig. 6). Morphologically, N. egyptiaca COAD 2167 has smaller conidiogenous cells (6-11 × 2-3 μm), number of apical appendages ranging from 1-3, larger conidia (21.5-28 × 5-7 μm), a little shorter apical appendage (11-21 μm) and shorter basal appendage (1.5-5.5 μm) than N. egyptiaca CBS 140162. However, there minor morphological differences are commonly observed on different isolates of the same Neopestalotiopsis species (Maharachchikumbura et al. 2014). Neopestalotiopsis egyptiaca is only reported causing leaf spot disease on Mangifera indica (Anacardiaceae) in Africa (Egypt) (Crous et al. 2015). To our knowledge, this is the first report of Neopestalotiopsis egyptiaca from the American continent. This is also the first report of the species causing post-harvest rot disease on guava (Psidium guajava) fruits. These findings may be helpful for further studies on quarantine programs and management measures.

Simple sporangiophores with inconspicuous columellae (arrows). E. Sporangiospores. Scale bars: 16, 25, 30 and 10 µm, respectively. 

Description: Colonies low, up to 4 mm in height, 7 cm diam., velvety, initially white becoming drab-grey to fuscous on MEA at 25°C. Reverse slightly zoned and cream-colored. Sporangiophores simple or with simple branching (up to 7) arising from the same point, sympodial branching also observed, often swollen at the point of branching; 120-300 (-380) µm long, reaching 3-5 μm in width close to the base, 1-2 septate, rarely (-4), tapering gradually toward apex. Sporangia globose 7-18 µm diam., multi-spored, initially hyaline, becoming greyish, walls evanescent, infrequently collared. Columellae mostly inconspicuous or absent, when present in the larger sporangiophores they are very small, slightly convex, smooth-walled, 2-3 µm in diam. Sporangiospores: diverse in shape, mostly globose, 2-5 µm in diam.; also ellipsoidal, 4.5 × 2.5 µm, slightly angular, 3.5 µm diam. Chlamydospores present in aerial mycelium, variable in shape, globose, subglobose and doliform. Zygosporangia not observed.

Cultures and temperature tests: On MEA at 10 ºC, very limited growth (2.2 cm in diam. in seven days, < 1 mm in height), no reproductive structures; at 15 ºC, small colonies (< 1 mm in height) with slow growth (4.5 cm in diam. in seven days), weak sporulation, sporangiophores simple or slightly branched; at 20 ºC, colonies growing up to 3 mm in height with fast growth (7 cm in five days), weak sporulation; at 25 ºC, colonies growing 7 cm in four days and up to 3 mm in height, strong sporulation; at 35 ºC, no growth and sporulation.

Material examined: Umbelopsis isabellina. BRAZIL. Pernambuco: Buíque, Catimbau National Park (8°36′35′′S 37°14′40′′W), isolated as an endophyte from leaves of Tillandsia catimbauensis Bromeliaceae, K.T.L.S. Freire (strain: URM 7862; isolates: T71.211, T146.212, T145.224, T87.228, T169.253, T186.294).

GenBank accession numbers: URM 7862: ITS MH220327. T71.211: ITS MH220324. T146.212: ITS MH220325. T145.224: ITS MH220326. T186.294: ITS MH220328.

Notes - The type material of Umbelopsis isabellina was first reported from soil in The Netherlands and previously assigned to the genus Micromucor, later to Mortierella (Oudemans & Koning 1902; Meyer & Gams 2013) and now it is accepted as Umbelopsis (Spatafora et al. 2016). After the original description, there have been some reports from different substrates and hosts (Hoff et al. 2004; Budziszewska et al. 2010). In the semiarid region of Brazil, U. isabellina has been reported from soil samples (Upadhyay 1967). The phylogenetic inference obtained in this study (Fig. 9) using ITS sequences and morphological features, such as the colony characters of low or flat, zoned, at first white and later becoming dingy grey, spreading, velvety, sporangiophores simple or sympodially branched, tapering gradually toward apex, often septate, bearing sporangia terminally (120-300 µm long), sporangia globose, non-columellate or small columellae on dehiscence, sporangiospores (ellipsoidal, angular and mostly globose, 2-5 µm in diam.), and the presence of chlamydospores, justified the identification of these endophytic isolates as U. isabellina (Meyer & Gams 2013). The isolates obtained as endophytes from leaves of the bromeliad Tillandsia catimbauensis in the Brazilian tropical dry forest is the first record of this species as an endophytic fungus in Brazil.
