Mycosphere 4(4), 653–659, Doi 10.5943/mycosphere/4/4/1 Abstract Mycena lohitha sp. nov. and M. babruka sp. nov. are described from Kerala State, India and are assigned to sect. Galactopoda. Comprehensive descriptions, photographs, and comparisons with phenetically similar species are provided. A key is provided that differentiates all known species of the sect. Galactopoda. The circumscription of the section needs to be expanded to include some of the species presently assigned to it including the new species described here and a provisional, expanded circumscription of the section is followed in this paper. Key words – Agaricales – Basidiomycota – biodiversity – Mycenaceae – taxonomy Introduction Section Galactopoda (Earle) Maas Geest. of the genus Mycena (Pers.) Roussel (Mycenaceae, Agaricales, Basidiomycota) comprises species with medium-sized basidiomata with stipes that often exude a fluid when cut, exhibit coarse whitish fibrils at the base, and turn blackish when dried. Additionally they have ellipsoid and amyloid basidiospores, cheilocystidia that are generally fusiform and often with coloured contents, and hyphae of the pileipellis and stipitipellis covered with excrescences and diverticulate side branches. -
Wood Decay Fungi in Landscape Trees
Pest Notes, Publication 74109 Revised August 2019 Integrated Pest Management for Home Gardeners and Landscape Professionals Wood Decay Fungi in Landscape Trees everal fungal diseases, sometimes called heart rots, Ssap rots, or canker rots, decay wood in tree trunks Figure 1. White rot of oak. and limbs (Figures 1 and 2). Under conditions favor- ing growth of specific rot fungi, extensive portions of the wood of living trees can decay in a relatively short time (i.e., months to years). Decay fungi reduce wood strength and may kill storage and conductive tissues in the sapwood. While most species of woody plants are subject to trunk and limb decay, older and weaker trees are most susceptible. DAMAGE Decay fungi destroy cell wall components; including cellulose, hemicellulose, and lignin, that make up the woody portion of a tree. Depending on the organism, decay fungi can destroy the living (sapwood) or the central core (heartwood) part of the tree. Decay isn’t always visible on the outside of the tree, except where the bark Figure 2. Heart brown rot in a conifer trunk. has been cut or injured, when a cavity is present, or when rot fungi produce reproductive structures. Wood decay can make trees hazardous, of wood weight can result in 70 to 90% as infected trunks and limbs become loss in wood strength. Many branches unable to support their own weight and that fall from trees appear sound, but fall, especially when stressed by wind, upon analysis, they were colonized by Authors: heavy rain, or other conditions.

Bot 316 Mycology and Fungal Physiology
BOT 316 MYCOLOGY AND FUNGAL PHYSIOLOGY Dr Osondu Akoma 2011 BOT 316 MYCOLOGY AND FUNGAL PHYSIOLOGY INTRODUCTION HISTORICAL BACKGROUND Mycology is a classical translation of the Greek word Mykes logos which means mushroom discussion, thus mycology is the study of fungi. In the past this area of science was limited to the study of mushrooms but as science developed, the scope of the subject widened far beyond the objects seen with the naked eyes with the discovery of microscopes. The development of mycology cannot be isolated from that of science. The ancestry of fungi is ancient, dating back to the Devonian and Precambrian eras. The history is also influenced by calamities and man has always kept record from time and as such the first record of fungi was not that of observing fungi directly but that of their harmful effects. The Romans and Greeks have a lot in their records. Even in the Holy Bible there are many references of the fungi and their effects; Leviticus 14: 4-48, 1Kings 8:37, Deuteronomy 28:22. The first indication that man saw fungi as food was a report of death at Icarius. The first book devoted to fungi is the Van Sterbeek’s “Theatrum Fungerium” in 1675 and this work distinguished the edible from the poisonous mushrooms. The discovery of the microscope led to the systematic study of the fungi. Robert Hooke was credited with the first illustration of micro fungi in 1667 in his work titled Micrographa . The Greeks and Romans regarded fungi as mysterious things. They were regarded as the “evil formats of the earth originating from the mouth of vipers”. -
Two New Species of Dermoloma from India
Phytotaxa 177 (4): 239–243 ISSN 1179-3155 (print edition) www.mapress.com/phytotaxa/ PHYTOTAXA Copyright © 2014 Magnolia Press Article ISSN 1179-3163 (online edition) http://dx.doi.org/10.11646/phytotaxa.177.4.5 Two new species of Dermoloma from India K. N. ANIL RAJ, K. P. DEEPNA LATHA, RAIHANA PARAMBAN & PATINJAREVEETTIL MANIMOHAN* Department of Botany, University of Calicut, Kerala, 673 635, India *Corresponding author: [email protected] Abstract Two new species of Dermoloma, Dermoloma indicum and Dermoloma keralense, are documented from Kerala State, India, based on morphology. Comprehensive descriptions, photographs, and comparison with phenetically similar species are provided. Key words: Agaricales, Basidiomycota, biodiversity, taxonomy Introduction Dermoloma J. E. Lange (1933: 12) ex Herink (1958: 62) (Agaricales, Basidiomycota) is a small genus of worldwide distribution with around 24 species names (excluding synonyms) listed in Species Fungorum (www.speciesfungorum. org). The genus is characterized primarily by the structure of the pileipellis, which is a pluristratous hymeniderm made up of densely packed, subglobose or broadly clavate cells (Arnolds 1992, 1993, 1995). Although Dermoloma is traditionally considered as belonging to the Tricholomataceae, Kropp (2008) found that D. inconspicuum Dennis (1961: 78), based on molecular data, had phylogenetic affinities to the Agaricaceae. Most of the known species are recorded from the temperate regions. So far, only a single species of Dermoloma has been reported from India (Manimohan & Arnolds 1998). During our studies on the agarics of Kerala State, India, we came across two remarkable species of Dermoloma that were found to be distinct from all other previously reported species of the genus. They are herein formally described as new. -
Bulk Isolation of Basidiospores from Wild Mushrooms by Electrostatic Attraction with Low Risk of Microbial Contaminations Kiran Lakkireddy1,2 and Ursula Kües1,2*
Lakkireddy and Kües AMB Expr (2017) 7:28 DOI 10.1186/s13568-017-0326-0 ORIGINAL ARTICLE Open Access Bulk isolation of basidiospores from wild mushrooms by electrostatic attraction with low risk of microbial contaminations Kiran Lakkireddy1,2 and Ursula Kües1,2* Abstract The basidiospores of most Agaricomycetes are ballistospores. They are propelled off from their basidia at maturity when Buller’s drop develops at high humidity at the hilar spore appendix and fuses with a liquid film formed on the adaxial side of the spore. Spores are catapulted into the free air space between hymenia and fall then out of the mushroom’s cap by gravity. Here we show for 66 different species that ballistospores from mushrooms can be attracted against gravity to electrostatic charged plastic surfaces. Charges on basidiospores can influence this effect. We used this feature to selectively collect basidiospores in sterile plastic Petri-dish lids from mushrooms which were positioned upside-down onto wet paper tissues for spore release into the air. Bulks of 104 to >107 spores were obtained overnight in the plastic lids above the reversed fruiting bodies, between 104 and 106 spores already after 2–4 h incubation. In plating tests on agar medium, we rarely observed in the harvested spore solutions contamina- tions by other fungi (mostly none to up to in 10% of samples in different test series) and infrequently by bacteria (in between 0 and 22% of samples of test series) which could mostly be suppressed by bactericides. We thus show that it is possible to obtain clean basidiospore samples from wild mushrooms. -

KEY WORDS: Entolomataceae, Greater Antilles, Tricholomataceae INTRODUCTION Over the past decade several papers have been published on members of Agaricales from Puerto Rico (Baroni and Lodge, 1998; Baroni et al., 1999; Cantrell and Lodge, 2000 & 2001; Guzmán, et al., 1997; Lodge, 1988; Lodge et al.. 2001; Lodge and Pegler, 1990; Miller et al., 2000; Pegler, et al., 1998; Singer and Lodge, 1988. Much of the previous literature discussing publications on agarics for Puerto Rico can be found in Baroni and Lodge (1 998) and Lodge (1 996). A recent study by one of us (BO) on the agaric mycota in the Guilarte State Forest, a wet subtropical forest located in the Cordillera Central of southwestern Puerto Rico (18°07N, 66°27W), has turned up two new species of agarics. Previously Bor (1969) had reported only nine species total from the Guilarte State Forest in Puerto Rico. We now have documented an additional 14 species, which includes the two new taxa described below. However, many collections from the Guilarte State Forest have yet to be identified to species, and thus this number will continue to rise. -
Microbiological Spoilage of Fruits and Vegetables
Microbiological Spoilage of Fruits and Vegetables Margaret Barth, Thomas R. Hankinson, Hong Zhuang, and Frederick Breidt Introduction Consumption of fruit and vegetable products has dramatically increased in the United States by more than 30% during the past few decades. It is also estimated that about 20% of all fruits and vegetables produced is lost each year due to spoilage. The focus of this chapter is to provide a general background on microbiological spoilage of fruit and vegetable products that are organized in three categories: fresh whole fruits and vegetables, fresh-cut fruits and vegetables, and fermented or acidified veg- etable products. This chapter will address characteristics of spoilage microorgan- isms associated with each of these fruit and vegetable categories including spoilage mechanisms, spoilage defects, prevention and control of spoilage, and methods for detecting spoilage microorganisms. Microbiological Spoilage of Fresh Whole Fruits and Vegetables Introduction During the period 1970–2004, US per capita consumption of fruits and vegetables increased by 19.9%, to 694.3 pounds per capita per year (ERS, 2007). Fresh fruit and vegetable consumption increased by 25.8 and 32.6%, respectively, and far exceeded the increases observed for processed fruit and vegetable products. If US consump- tion patterns continue in this direction, total per capita consumption of fresh fruits and vegetables would surpass consumption of processed fruits and vegetables within the next decade. This shift toward overall increased produce consumption can be attributed, at least in part, to increased awareness in healthy eating habits as revealed by a broad field of research addressing food consumption and health and promoted by the M. -
