A New Section and Two New Species of Podaxis (Gasteromycetes) from South Africa
S.Afr.l. Bot., 1989,55(2): 159-164 159 A new section and two new species of Podaxis (Gasteromycetes) from South Africa J.J.R. de Villiers, A. Eicker* and G.C.A. van der Westhuizen Department of Botany, University of Pretoria, Pretoria, 0001 Republic of South Africa Accepted 7 September /988 Podaxis africana De Villiers, Eicker & van der Westhuizen and P. rugospora De Villiers, Eicker & van der Westhuizen, two new species from Transvaal are described and illustrated. A new section, Umbricorticalis De Villiers, Eicker & van der Westhuizen is proposed in the genus Podaxis to accommodate P. africana. Morphologically P. africana resembles P. microporus McKnight but it is distinguished by its large globose, subglobose to broadly ovoid spores, the absence of a 'pin prick' pore structure, the black gleba, and the deep orange to strong brown inner cortex of the stipe. P. rugospora is allied to P. pistillaris (L. ex Pers.) Fr. emend. Morse from which it differs by reason of the hyaline, narrow, flattened, occasionally septate capillitium threads and the grayish-olive, light olive or light to moderate yellowish-brown gleba. The most remarkable character of these new species is the rugose spores. Podaxis africana De Villiers, Eicker & van der Westhuizen en P. rugospora De Villiers, Eicker & van der Westhuizen, twee nuwe spesies van Transvaal word beskryf en ge·illustreer. 'n Nuwe seksie, Umbricorticalis De Villiers, Eicker & van der Westhuizen in die genus Podaxis word voorgestel om P. africana te akkommodeer. Morfologies toon P. africana 'n ooreenkoms met P. microporus McKnight maar word deur die groot bolvormige, subbolvormige tot bykans eiervormige spore, die afwesigheid van 'n 'naaldprik'-porie struktuur, die swart gleba en die diep oranje tot sterk bruin binneste korteks van die stipe. -

Pheromone receptor Consistent with a role of mating type in mediating cytoplasmic-nuclear genomic conflict, Agaricomycetes have evolved away from a haploid yeast phase towards hyphal fusions that display reciprocal nuclear migration after mating rather than cytoplasmic fusion. Importantly, the evolution of this mating behavior is precisely timed with the onset of diversification of mating type alleles at the pheromone/receptor mating type loci that are known to control reciprocal nuclear migration during mating. -

Mycosphere 10(1), 310–489, Doi 10.5943/mycosphere/10/1/7 Abstract Leotiomycetes is regarded as the inoperculate class of discomycetes within the phylum Ascomycota. Taxa are mainly characterized by asci with a simple pore blueing in Melzer’s reagent, although some taxa have lost this character. The monophyly of this class has been verified in several recent molecular studies. However, circumscription of the orders, families and generic level delimitation are still unsettled. This paper provides a modified backbone tree for the class Leotiomycetes based on phylogenetic analysis of combined ITS, LSU, SSU, TEF, and RPB2 loci. In the phylogenetic analysis, Leotiomycetes separates into 19 clades, which can be recognized as orders and order-level clades. -
ARMILLARIA ROOT ROT: a DISEASE of NATIVE and INTRODUCED TREES Forests Fact Sheet
ARMILLARIA ROOT ROT: A DISEASE December 2003 OF NATIVE AND INTRODUCED TREES ISSN 1440-2262 Ian W. Smith & David I. Smith, Forest Science Centre Background Armillaria root rot, unlike some familiar pests and diseases, occurs naturally in many forests of Victoria. This aggressive fungal pathogen has so far seriously damaged about 2000 ha of mixed species eucalypt forest in the Mt. Cole and Wombat State Forests with minor outbreaks in other areas of Victoria. It attacks many species of native trees and shrubs including eucalypts and wattles, and has also been recorded on introduced trees and shrubs growing in parks and botanical and domestic gardens. Symptoms and Signs of disease The fungus can kill trees and shrub species of any age and has a very wide host range. Young trees and seedlings may, over a period of a few weeks, suddenly wilt and the leaves fall. They may die within 3-6 months of the onset of the first symptoms. Larger trees, especially those with a sizeable trunk, die more slowly. The initial symptoms of sparse foliage and branch dieback may continue for up to 3 years before the remaining foliage begins to wilt, the leaves turn brown and the trees die (Figure 1). Other pathogens and environmental disorders can produce similar symptoms, so it is wise to check that Armillaria infection is present by examining a tree showing advanced disease symptoms. To do this, remove some of the inner bark at the base of the tree and look for fan-shaped, creamy-white fungal sheets (Figure 2). Often the bark tissue around the fungal sheets turns chocolate brown in colour. -

Current Research in Environmental & Applied Mycology 4 (1): 117–124, Doi 10.5943/cream/4/1/10 Abstract Field surveys and collection of the basidiocarps of wood-rotting fungi were carried out in eight forest stands of East Khasi Hills district of Meghalaya, India. Seventy eight wood-rotting fungi belonging to 23 families were identified. The undisturbed Mawphlang sacred grove was found to harbour a much larger number of the wood-rotting fungi (33.54 %) as compared to the other forest stands studied. Similarly, logs also harboured the maximum number of wood-rotting fungi (59.7 %) while living trees harboured the least (7.8%). Microporus xanthopus had the highest frequency percentage of occurrence with 87.5 %, followed by Cyclomyces tabacinus, Microporus affinis and Trametes versicolor with 62.5 %. Majority of the wood-rotting fungi are white-rot fungi (89.61%) and only few are brown-rots. -

The Isolation, Purification and Analysis of the Melanin Pigment Extracted from Armillaria Mellea Rhizomorphs
Available online at www.worldscientificnews.com WSN 100 (2018) 135-153 EISSN 2392-2192 The isolation, purification and analysis of the melanin pigment extracted from Armillaria mellea rhizomorphs Łukasz Łopusiewicz Center of Bioimmobilisation and Innovative Packaging Materials, Faculty of Food Sciences and Fisheries, West Pomeranian University of Technology in Szczecin, 35 Janickiego Str., Szczecin 71-270, Poland E-mail address: [email protected] ABSTRACT The aim of present study was isolation and characteriation of raw and purified melanin from Armillaria mellea rhizomorphs. Native melanin was isolated from the rhizomorphs of A. mellea by alkaline extraction. Obtained pigment was purifed by acid hydrolysis and washed by organic solvents. Chemical tests, FT-IR and Raman spectroscopy analysis were conducted to determine the melanin nature of the isolated pigment. UV-Vis, transmittance and colour properties were evaluated. Antioxidant activity was determined using ABTS and antibacterial activity by a well diffusion method. The results of the study demonstrated that melanins isolated from A. mellea rhizomorphs had antioxidant, light barrier and antibacterial properties. A purified form of melanin offered better light properties and higher antioxidant activity than the raw form. Both melanins showed antimicrobial activity, raw melanin form had broader activity compared to the pure form. This study revealed that A. mellea rhizomorphs may be considered as a promising source of natural melanin. Isolated pigments presented all the physical and chemical properties common to natural and synthetic melanins. Raw and purified melanins showed differences in chemical composition, antioxidant activity and light barrier properties. Results of this study suggest that, melanins from A. mellea could be applied in the food, cosmetics and pharmaceutical industries. -

Here we studied the relationships between Lentinus subg. Lentinus sensu Pegler (i.e. sections Lentinus, Tigrini, Dicholamellatae, Rigidi, Lentodiellum and Pleuroti and polypores that share similar morphological characters). We generated sequences of internal transcribed spacers (ITS) and Copyright 2015 by The Mycological Society of America. partial 28S regions of nuc rDNA and genes encoding the largest subunit of RNA polymerase II (RPB1), focusing on Lentinus subg. Lentinus sensu Pegler and the Neofavolus group, combined these data with sequences from GenBank (including RPB2 gene sequences) and performed phylogenetic analyses with maximum likelihood and Bayesian methods. We also evaluated the transition in hymenophore morphology between Lentinus, Neofavolus and related polypores with ancestral state reconstruction. -
Detection, Recognition and Management Options for Armillaria Root Disease in Urban Environments
Detection, recognition and management options for Armillaria root disease in urban environments Richard Robinson Department of Environment and Conservation, Manjimup, WA 6258 Email: [email protected] Abstract Armillaria luteobubalina, the Australian honey fungus, is an endemic pathogen that attacks and kills the roots of susceptible trees and shrubs, causing a root rot. The fungus colonises the cambium and trees eventually die when the root collar is girdle and it spreads from host to host by root contact. The disease is referred to as armillaria root disease (ARD). In recent years, reports of ARD killing trees and shrubs in urban parks and gardens have increased. When investigated, infection is usually traced to stumps or the roots of infected trees that were left following clearing of the bush when towns or new suburbs were established. The Australian honey fungus is indigenous to southern Australia, and is common in all forest, woodland and some coastal heath communities. In undisturbed environments, ARD is generally not the primary cause of death of healthy forest or woodland trees but more usually it kills trees weakened by competition, age-related decline or environmental stress and disturbance. In gardens and parks, however, the honey fungus can become a particularly aggressive pathogen and in this situation no native or ornamental trees and shrubs appear to be resistant to infection. The life cycle of the fungus consists of a parasitic phase during which the host is infected and colonised. The time taken for plants to succumb to disease varies, but may take decades for large trees. A saprophytic phase follows, during which the root system and stump of the dead host is used by the fungus as a food base.
