Paraphaeosphaeria barrii, a new species on Yucca schidigera from Mexico

Neophaeosphaeria and Phaeosphaeriopsis segregates of Paraphaeosphaeria

“…The anamorphs of both species produce smooth-walled, pale brown conidia from inconspicuous phialides with some periclinal thickening, typical of Microsphaeropsis. They are phylogenetically distant and morphologically different from the eight other species studied (Caˆmara et al 2001, Checa et al 2002.…”

“…1917 (Sutton 1980). Previous work demonstrated that Paraphaeosphaeria is polyphyletic (Caˆmara et al 2001, Checa et al 2002 and the ten species studied grouped in at least three clades. Clade A (Caˆmara et al 2001) included the type species Para.…”

“…Results of morphological studies of the ten previously described species of Paraphaeosphaeria that are treated in this paper were reported elsewhere (Caˆmara et al 2001, Checa et al 2002. Cultures of the newly described Phaeosphaeriopsis amblyspora were obtained by excising an ascoma from host material, opening it in a drop of sterile tap water, isolating released asci, washing individual asci three times in sterile tap water, and placing them on the surface of Difco Potato Dextrose Agar (PDA) in Petri dishes.…”

Nuevos registros de Pleosporales (Ascomycota) para México

“…En México se conoce muy poco sobre los Pleosporales, hasta ahora se contabilizan 71 registros de especies pertenecientes a este Orden (Ahmed y Cain, 1972;Álvarez et al, 2016;Câmara et al, 2003;Chacón-Zapata et al, 2014;Chacón-Zapata y Tapia-Padilla, 2013;Checa et al, 2002;Cibrián-Tovar et al, 2007;Fries, 1851;González et al, 1998González et al, , 2001González et al, , 2007Guzmán-Dávalos et al, 1983;Hernández-Castillo et al, 2002;Méndez-Mayboca et al, 2010;Mendoza et al, 1981;Montes, 1992;San Martín-González, 1996;San Martín-González y Lavín, 1999;Udagawa y Kobayasi, 1979;Zenteno et al, 1955), destacando especies coprófilas, saprobias, de ambientes terrestres, marinos y parásitas de plantas.…”

First report of Phaeosphaeriopsis glaucopunctata as the cause of leaf spot and necrosis on Ruscus aculeatus in Australia

“…Butcher's Broom, Ruscus aculeatus (family Asparagaceae), is an evergreen, perennial shrub native to western and southern Europe, northwest Africa, and southwest Asia. Paraphaeosphaeria glauco-punctata has been reported as the causal organism of leaf spot and necrosis on Ruscus (Camara et al 2001;Checa et al 2002). However, recently P. glaucopunctata was transferred to the genus Phaeosphaeriopsis and described as Phaeosphaeriopsis glaucopunctata (http://www.indexfungorum.org/names/ Names.asp.).…”
