Sargento Cabral 2131, CC 209 Corrientes Capital, CP 3400, Argentina 2Instituto de Investigaciones Biotecnológicas (UNSAM-CONICET) Intendente Marino Km 8.200, Chascomús, Buenos Aires, CP 7130, Argentina CORRESPONDENCE TO *: [email protected] ABSTRACT— A species checklist of 86 genera and 709 species belonging to the families Tricholomataceae and Polyporaceae occurring in Argentina, and including all the species previously published up to year 2011 is presented. KEY WORDS—Agaricomycetes, Marasmius, Mycena, Collybia, Clitocybe Introduction The aim of the Checklist of the Argentinean Agaricales is to establish a baseline of knowledge on the diversity of mushrooms species described in the literature from Argentina up to 2011. The families Amanitaceae, Pluteaceae, Hygrophoraceae, Coprinaceae, Strophariaceae, Bolbitaceae and Crepidotaceae were previoulsy compiled (Niveiro & Albertó 2012a-c). In this contribution, the families Tricholomataceae and Polyporaceae are presented. Materials & Methods Nomenclature and classification systems This checklist compiled data from the available literature on Tricholomataceae and Polyporaceae recorded for Argentina up to the year 2011. Nomenclature and classification systems followed Singer (1986) for families. The genera Pleurotus, Panus, Lentinus, and Schyzophyllum are included in the family Polyporaceae. The Tribe Polyporae (including the genera Polyporus, Pseudofavolus, and Mycobonia) is excluded. There were important rearrangements in the families Tricholomataceae and Polyporaceae according to Singer (1986) over time to present. Tricholomataceae was distributed in six families: Tricholomataceae, Marasmiaceae, Physalacriaceae, Lyophyllaceae, Mycenaceae, and Hydnaginaceae. Some genera belonging to this family were transferred to other orders, i.e. Rickenella (Rickenellaceae, Hymenochaetales), and Lentinellus (Auriscalpiaceae, Russulales).

(Phragmidiaceae, Pucciniales), causing witches’ brooms on Rosa bracteata Yoshitaka Ono Faculty of Education, Ibaraki University, 2-1-1 Bunkyo, Mito, Ibaraki 310-8512 Japan Correspondence to: [email protected] Abstract—Caeomatoid rust infection has been observed on Rosa bracteata plants at a single site in Ishigaki Island, Okinawa, Japan, since 1995. The fungus (not previously known in Japan) was identified as Caeoma warburgiana by its characteristic systemic infection causing witches’ brooms and its spore morphology. Uredinial and telial sori were found on the leaves of the witches’ brooms of the infected rose plants at the same site in 2009. The urediniospores were pedicellate and echinulate. The teliospores were composed of two to four linearly arranged, thin-walled cells on a short pedicel. Caeoma-type aecia, Uredo-type uredinia and pedicellate teliospores with two to four linearly arranged cells are characteristic of the genus Kuehneola. Identical telia and teliospores were found in the lectotype of C. warburgiana. Caeoma warburgiana is recombined as Kuehneola warburgiana. Key words —Asia, life cycle, nomenclature, taxonomy Introduction Rosa bracteata is an evergreen perennial shrub, native of southern regions of China, growing in mixed forests, scrub, and sandy hills at low altitudes and seashores (Wu & Raven 2003). The plants also occur at coastal areas of Taiwan and adjacent islands of south Japan (Satake et al. 1989, Liu et al. 2000, Wu & Raven 2003).

  • Occurrence of Gymnoconia Peckiana in Turkey
    Pak. J. Bot., 36(4): 897-899, 2004. OCCURRENCE OF GYMNOCONIA PECKIANA IN TURKEY ELŞAD HÜSEYIN*, FARUK SELÇUK AND MAKBULE KARAHAN Department of Biology, Kırşehir Arts and Sciences Faculty, Gazi University, 40100 Kırşehir, Turkey Abstract Gymnoconia peckiana (Howe) Trott., a rust fungus belonging to the family Pucciniaceae collected during a field trip around Trabzon in 1999 is reported as a new record for Turkey. Introduction Higher plants of Turkey have been well studied but the mycobiota has not been extensively investigated and most of the studies deal with macromycetes generally Agaricoid fungi. Reports on micromycetes, including rust fungi, has been made (Bremer et al., 1947, 1952; Petrak, 1953). Data concerning the Uredinales are fragmentary which has been published as diseases of cultivated plants (Karel, 1958) and on mycoflora of Turkey (Göbelez, 1963). As a result of these and other studies (Henderson, 1957, 1959, 1961, 1964; Tamer et al., 1998; Kırbağ et al., 2001; Hüseyin & Kırbağ, 2003), about 290 species of rust fungi are recorded from Turkey. The present reports discribes the occurrence Gymnoconia peckiana from Turkey. Materials and Methods The plant material was collected from different localites of Trabzon province during July-August 1999. The host specimens were prepared according to established herbarium techniques. Microscopical examinations of fungi were performend using Nikon research microscopes. The specimens were identified after reference to related literature (Gäumann, 1959; Azbukina, 1974, 1975; Cummins & Hiratsuka, 2003; Bremer et al., 1952; Göbelez, 1963; Öner et al., 1974). The host specimen was identified using Flora of Turkey (Davis, 1965-1985). The collection is deposited at Gazi University, Kırşehir Sciences and Arts Faculty Herbarium in Kırşehir Province (KRFEF) of Turkey.

Dr. Himmet TEZCAN İnsan sağlığı üzerine olumlu etkileri olduğunu ortaya koyan çalışmalar ve ayrıca taşıdığı tat ve aroması nedeniyle son yıllarda hem sofralık olarak tüketim hem de gıda sanayi alanında Böğürtlen (Rubus fruticocus L.) meyvesine olan talep artmaktadır. Ülkemizde de ürüne artan taleple birlikte böğürtlen üretimine eğilimin arttığı görülmektedir. Ülkemizde böğürtlenin yaklaşık % 84’ü Bursa ilinde üretilmektedir. Böğürtlen üretiminde fungal hastalıklar verimi etkileyen en önemli faktör olmakla birlikte ülkemizde bu hastalıkların mücadelesinde ruhsatlı bir fungisit bulunmamaktadır.

  • Orange Berry Rust
    Plant Disease Diagnostic Clinic Plant Pathology and Plant‐Microbe Biology Section 334 Plant Science Building Ithaca, NY 14853‐5904 Orange Rust: Gymnoconia sp. and Arthuriomyces sp. Introduction been assigned to them. The form on black raspberry is Orange rust is a disease of black berry and black caused by a fungus known as Arthuriomyces peckianus, raspberry. Purple raspberry may also become infected, while the form more common on blackberry is but red raspberry is resistant. This rust occurs in two known as Gymnoconia nitens. Orange rust is one of different forms with very similar symptoms. One the more serious diseases of susceptible brambles in form has a long cycle and affects mainly black the Northeast. It should not be confused with the late raspberry, and the other has a short cycle and affects leaf rust disease of red raspberries. mainly blackberry. Gymnoconia peckiana was the name originally given to the fungus that causes orange rust, but some morphological differences were eventually identified between the two forms, and now separate scientific names have Figure 2: Sporulation on lower leaf surface of black raspberry (June in New York) (provided by S. Jensen, Cornell University) Symptoms and Signs Lower leaf surfaces become covered with blister-like Figure 1: Symptoms on upper leaf surface of black raspberry masses of yellow-orange spores by late May or early (provided by S. Jensen, Cornell University) June. These spores serve to spread the disease to other plants. In addition, heavily infected leaves may die, and infected shoots will be weak, spindly and have very few, if any thorns.
