This paper is based on herbarium study, literature review, and collections made in Caxiuana Forest, Para, Brazil. Forty-six specimens ofUredinales were studied. Six species ofPhakopsoraceae and six species ofUropyxidaceae were identified, belonging to the genera Batistopsora, Cerotelium, Crossopsora, Dasyspora, Kimuromyces, Phakopsora, Phragmidiella, Porotenus, Prospodium, and Uropyxis. Batistopsora crucis-filii Dianese, Kimuromyces cerradensis Dianese, Santos, Medeiros & Furlanetto and Phragmidiella bignoniacearum (Dale) Buritid & Hennen are new records for Amazonia. Analytic keys to the species is presented. Key words: biodiversity, rust fungi, taxonomy RESUMO - (Fungos das familias Phakopsoraceae e Uropyxidaceae (Uredinales) da Floresta Nacional de Caxiuana, Para, Brasil).

    Familia Phakopsoraceae..... FAMILIA PHAKOPSORACEAE ( Fungi: Uredinales) GENERALIDADES Y AFINIDADES Pablo Buriticá Céspedes1 RESUMEN Se presentan aspectos generales sobre importancia de la familia Phakopsoraceae, afinidad y relaciones filogenéticas entre géneros, rango de hospedantes, distribución geográfica y ciclos de vida. Palabras clave: Uredinales, Phakopsoraceae. ABSTRACT General aspects in the Phakopsoraceae family importance, philogenetic affinities within genera, hosts range, geografic distribution and life cycles are presented. Key words: Uredinales, Phakopsoraceae. INTRODUCCION Dentro del concepto de clasificación taxonómica, la agrupación en familias, para el Orden Uredinales (Fungi: Basidiomycota: Heterobasidiomycia), no ha sido aún, bien desarrollado y por ende su uso común y rutinario es incipiente, obviado o rechazado. Sin embargo, en los últimos años se ha despertado mucho interés en este tópico, dentro de los Uredinólogos, debido a los avances obtenidos en el conocimiento de los distintos géneros estudiados como grupos (Cummins, 1959; Cummins e Hiratsuka, 1983); al valor taxonómico de los espermogonios en el nivel supragenérico (Hiratsuka y Cummins, 1963); a los estudios globales de los uredinios (Sathe, 1977); a los estudios de evolución, diversidad y delimitación de grupos de géneros dentro de las familias u órdenes de las plantas hospedantes (Leppik, 1972; Savile, 1976, 1979); a los estudios morfológicos aplicados a las variantes evolutivas de las estructuras en los ciclos de vida (Hennen y Buriticá, 1980), especialmente, en Endophyllaceae (Buriticá, 1991) y Pucciniosireae (Buriticá y Hennen, 1980); a los estudios sobre la ontogenia de los esporos (Hughes, 1970); y, al tratamiento sistemático de varios grupos, como Pucciniosireae (Buriticá y Hennen, 1980), géneros Chaconiaceos (Ono, 1983), Raveneliaceae (Leppik, 1972; Savile, 1989) y Phakopsoraceae (Buriticá, 1994, 1998).

  • Phakopsora Cherimoliae (Lagerh.) Cummins 1941
    -- CALIFORNIA D EPAUMENT OF cdfa FOOD & AGRICULTURE ~ California Pest Rating Proposal for Phakopsora cherimoliae (Lagerh.) Cummins 1941 Annona rust Domain: Eukaryota, Kingdom: Fungi Division: Basidiomycota, Class: Pucciniomycetes Order: Pucciniales, Family: Phakopsoraceae Current Pest Rating: Q Proposed Pest Rating: A Comment Period: 12/07/2020 through 01/21/2021 Initiating Event: In September 2019, San Diego County agricultural inspectors collected leaves from a sugar apple tree (Annona squamosa) shipping from a commercial nursery in Fort Myers, Florida to a resident of Oceanside. CDFA plant pathologist Cheryl Blomquist identified in pustules on the leaves a rust pathogen, Phakopsora cherimoliae, which is not known to occur in California. She gave it a temporary Q-rating. In October 2020, Napa County agricultural inspectors sampled an incoming shipment of Annona sp. from Pearland, Texas, that was shipped to a resident of American Canyon. This sample was also identified by C. Blomquist as P. cherimoliae. The status of this pathogen and the threat to California are reviewed herein, and a permanent rating is proposed. History & Status: Background: The Phakopsoraceae are a family of rust fungi in the order Pucciniales. The genus Phakopsora comprises approximately 110 species occurring on more than 30 dicotyledonous plant families worldwide, mainly in the tropics (Kirk et al., 2008). This genus holds some very important and damaging pathogen species including Phakopsora pachyrhizi on soybeans, P. euvitis on grapevine, and P. gossypii on cotton. Phakopsora cherimoliae occurs from the southern USA (Florida, Texas) in the north to northern Argentina in the south (Beenken, 2014). -- CALIFORNIA D EPAUMENT OF cdfa FOOD & AGRICULTURE ~ Annona is a genus of approximately 140 species of tropical trees and shrubs, with the majority of species native to the Americas, with less than 10 native to Africa.

Asian Journal of Mycology 4(1), 40–80, Doi 10.5943/ajom/4/1/5 Abstract Rust fungi show unique systematic characteristics among all fungal groups. A single species of rust fungi may produce up to five morphologically and cytologically distinct spore-producing structures thereby attracting the interest of mycologist for centuries. In India, the research on rust fungi started with the arrival of foreign visiting scientists or emigrant experts, mainly from Britain who collected fungi and sent specimens to European laboratories for identification. Later on, a number of mycologists from India and abroad studied Indian rust fungi and contributed a lot to knowledge of the rusts to the Indian Mycobiota.

Reinhard Berndt Received: 27 July 2011 / Accepted: 21 December 2011 / Published online: 22 January 2012 Ó Springer Science+Business Media B.V. 2012 Abstract The species richness of rust fungi (Pucciniales or Uredinales) in the neotropics is reviewed. Species numbers are presented for all neotropical countries and rust-plant- ratios calculated. It is discussed whether the ratio for a given region can be explained by the species richness of vascular plants alone or whether it is caused by additional factors. In the first case, ratios should apply globally and vary only slightly; in the second case, more diverging ratios are expected. Observed ratios ranged between 1:16 and 1:124 in the neotropics. The large differences are certainly influenced by unequal levels of investiga- tion, rendering interpretation difficult. Differences seem also to be influenced by the tax- onomic composition of floras regarding the percentage of host families or genera bearing different numbers of rust species.

Uredinial pustules mainly hypophyllous and on fruit, scattered or sometimes tending to be grouped around edge of leaf or in dew-drop runs on lamina, very pale reddish brown, often on reddish brown angular leaf spots (corresponding brown spots on upper surface coalescing and becoming necrotic), pulverulent, circular, up to 0.5 mm diam. Infected plants shed foliage prematurely, leaving immature fruit on the tree.

Quarantine has done little to prevent its movement through America, the Pacific, Africa, and in this report, South- East Asia. Puccinia psidii is reported for the first time from Indonesia on two genera of Myrtaceae, namely Eucalyptus and Melaleuca. The identity was confirmed by morphology, a molecular barcode comparison to an epitype specimen, and with a molecular phylogenetic approach. Comparison of seven microsatellite markers revealed that the genotype of the rust in Indonesia is the same as that found in Australia. The potential impacts of P. psidii in South-East Asia to the natural environment and plantation forestry are discussed in light of this first report from the region. Keywords: Melaleuca, Myrtaceae, Myrtle rust, Pucciniales, quarantine, Sphaerophragmiaceae, Uredinales Introduction Puccinia psidii (Pucciniales, Pucciniomycotina) causes rust on plants in the Myrtaceae and is a serious threat to Eucalyptus plantations and native ecosystems with myrtaceous species (Glen et al.
