Endophytes as potential pathogens of the baobab species Adansonia gregorii: a focus on the Botryosphaeriaceae

2011

View full text Add to dashboard Cite

Adansonia gregorii (baobab) is an iconic tree species occurring in the NW of Australia. Dying baobabs, A. digitata, have been reported from southern Africa and as A. gregorii is closely related to A. digitata, surveys were conducted to assess the health of the Australian baobab. The endophytic microflora of A. gregorii and surrounding tree species was sampled and the ability of these endophytes to cause disease in A. gregorii was determined. Endophytes were isolated from asymptomatic baobabs across 24 sites in the Kimberley region, north-west Australia (NW Australia). Material was also taken from surrounding native tree species at three sites. Material was also collected from asymptomatic and dying Adansonia species in the George Brown Darwin Botanic Gardens and from a dying baobab in a nursery in Broome. Endophytic fungi isolated from these samples were identified using morphological and molecular methods.Eleven botryosphaeriaceous species were identified along with 18 other nonbotryosphaeriaceous species; L. theobromae 1 was the most common species. The pathogenicity of the botryosphaeriaceous species to baobabs was determined by inoculating the taproot of seedlings and stems of young baobab trees. Lasiodiplodia theobromae was confirmed as a potentially significant pathogen of baobabs.2

“…This combination of characters is also found in R. rufulum, which has recently been shown to be a collective taxon including several species (Murillo, et al, 2009;Thambugala, et al, 2016). However, R. columbiense is not another segregate of the R. rufulum aggregate, since it differs from the latter in important features.…”

We describe a new species, Rhytidhysteron columbiense Soto-Medina & Lücking, from Colombia. It is a saprobic species found on decaying branches in montane rain forest remnants, characterized by boat-shaped ascomata up to 3 mm long and 1.8 mm wide, with brown-black disc and yellowish-green pruina, perpendicularly striate margins, and by 3-septate, ellipsoid to fusiform, red-brown ascospores 38-52 × 13-18 µm in size. The new species differs from all other species in the genus by the yellowish-green pruina on the margins of the ascomata and from R. rufulum s.lat. also in the larger ascospores, whereas R. brasiliense has similarly long ascospores, but differs in their broader width and their pigmentation, as they remain light brown at maturity. A provisional working key to known species of the genus in the world is provided based on literature data. © 2017. Acad. Colomb. Cienc. Ex. Fis. Nat. Key words:Rhytidhysteron; Ascospore; Pruina; Colombia.Una nueva especie de Rhytidhysteron (Ascomycota:Patellariaceae) de Colombia, con una clave provisional para las especies conocidas en el mundo ResumenSe describe la nueva especie Rhytidhysteron columbiense Soto-Medina & Lücking para Colombia. Es una especie saprobia encontrada sobre ramas en descomposición en remanentes de bosque montano lluvioso; se caracteriza por ascomas en forma de canoa de cerca de 3 mm de longitud y 1,8 mm de ancho, con disco marrón negruzco y pruina verde amarillosa, márgenes estriados perpendicularmente, y tres esporas septadas, elipsoides a fusiformes, marrón rojizas, de 38-52 × 13-18 µm de tamaño. Esta nueva especie difiere de las otras del género por la pruina verde amarillosa sobre los márgenes del ascoma, y de R. rufulum s.lat. por las esporas más grandes, mientras que R. brasiliense tiene las esporas grandes, pero difiere por sus ascosporas más anchas y por su pigmentación, que es de color pardo claro en la madurez. Se agrega una clave provisional para las especies del género en el mundo con base en datos de la literatura.

De éstas, Anteaglonium abbreviatum y Rhytidhysteron rufulum son nuevos registros para la entidad, Psiloglonium simulans se cita por primera vez para México y Gloniella tropicalis se describe como especie nueva para la ciencia.Palabras clave: especie nueva, Hysteriales, nuevos registros, Pleosporales, taxonomía. ABSTRACTFour species of hysterioid fungi belonging to the class Dothideomycetes of the phylum Ascomycota occurring in the tropical dry forest in the National Park of "Lagunas de Chacahua" in the state of Oaxaca are described and illustrated. Of these, Anteaglonium abbreviatum and Rhytidhysteron rufulum are new records for the state, Psiloglonium simulans is cited for the first time for Mexico and Gloniella tropicalis is described as a species new to science.
