Stinkhorns spotted in fields Abstract John Holmes, extension field crop specialist, reported that farmers are finding lots of stinkhorn mushrooms in soybean fields as they harvest. These fungi do not cause disease to plants or animals, but instead live a harmless existence on dead organic matter such as crop debris. They also are commonly found on decaying mulch. A stinkhorn begins life as an egg-like structure.

These fungi do not cause disease to plants or animals, but instead live a harmless existence on dead organic matter such as crop debris. They also are commonly found on decaying mulch. A stinkhorn begins life as an egglike structure. As the fungus develops, it expands into a 4 to 8inch tall mushroomlike body with a stalk and a slimy cap. The common name stinkhorn describes the putrid smell of the fungus.The odor attracts insects that then disperse the spores of the fungus on their bodies. Common stinkhorns found in Iowa include Mutinus caninus and Phallus impudicus. Mutinus caninus is the stinkhorn mushroom that has been recently spotted in fields. It is about 4 inches tall and has a pinkishred stalk with a dark slimy spore mass on the tip. Phallus impudicus is about 8 inches tall with a creamcolored stalk covered at the tip by slimy dark spores, with an open depression on the very top. Stinkhorn (Mutinus caninus).

While morels are considered edible and choice, one would definitely not want to eat a stinkhorn mushroom. The aroma alone would likely keep most people at a distance.

In addition to being fine mycological books in their own right, they have a great provenance, coming from the libraries of several members of the Fries family – the leading botanist and mycologist family in Sweden. All of the books are from the library of Nils Fries (1912–94), many from that of his grandfather Theodor (Thore) M. Fries (1832–1913), and a few from the library of Nils’ great grandfather Elias M. Fries (1794–1878), “fa- ther of Swedish mycology”. All three were botanists and professors at Uppsala University, as were many other members of the family, often with an orientation towards mycology. Nils Fries field of study was the procreation of mushrooms. Furthermore, Nils Fries has had a partiality for interesting provenances in his purchases – and many international mycologists are found among the former owners of the books in the catalogue. Four of the books are inscribed to Elias M. Fries, and it is probable that more of them come from his collection. Thore M.

Although this species was previously recorded from India, these reports did not include detailed morphological descriptions. Here we describe C. delicatus and provide illustrations and notes on fruitbody development, which has not been well characterized in the past. Key words — Phallaceae, peridial suture, primordia, sporoma, volva-gel Introduction Members of Phallales, commonly called stinkhorns, produce foul-smelling fruitbodies that attract insects. Their distinctive odor is produced by a combination of chemicals such as hydrogen sulfide and methyl mercaptan (List & Freund 1968). Stinkhorns typically develop very quickly, often within few hours, with the spore bearing structures (receptacles) emerging from globose to ovoid structures called ‘myco-eggs’ (Lloyd 1906, Pegler et al. 1995). The order Phallales comprises 2 families, 26 genera, and 88 species (Kirk et al. 2008). Clathroid members of family Phallaceae form multipileate receptacles (Gäumann 1952) with beautiful and bright colored sporomata. Clathrus is unique in having latticed, hollow, spherical or stellate receptacles with slimy glebae (spore masses) borne on their inner surfaces (Pegler et al.

ISSN: 0975-8585 Research Journal of Pharmaceutical, Biological and Chemical Sciences Analysis of the morphology and growth of the fungus Phallus indusiatus Vent. in Cocoa Plantation, Gaperta-Ujung Medan. Rama R Sitinjak* Faculty of Agrotechnology, Prima Indonesia University, Medan-Indonesia. ABSTRACT This research aimed to analyze the morphological characteristics and growth of the Phallus indusiatus Vent. which belong to the group Stinkhorn fungi. The method used is survey and description. This fungi grows individually, appear twice in one year on the ground that a pile of cocoa leaves that have died, during the heavy rainy season ends. The fungi was first found growing in the area of cocoa plantations in the village Gaperta-Ujung Medan, ie on August 6, 2013, around 9.00 am. Phallus indusiatus have major macroscopic morphological characteristics, namely the fruiting body has a height of ±19.13 cm, hood (cap or pileus) shaped brown cony and the side grooves with a width of ± 3 cm, and a height ± 2.6 cm, yellowish cream-colored gleba, has a white circular ring at the center of the stem, the stem (stalk or stipe) chewy white, cylindrical, cup (volva) gray that secrete mucus such as jellies, have a section that resembles roots (mycelium), has a coat or indusium such a network is creamy white and turned into golden yellow when wilting, that described from the bottom of the cap to the base of the stem. The process of growth and development of mushroom fruit body this happens starting from the egg stage (takes about 24 hours), and the budding stage, maturation stage, the stage of wilting (death) (third last stage of this only takes about 5 hours).

Global Warming and Mycoflora in the Baltic Region
ACTA MYCOLOGICA Dedicated to Vol. 41 (1): 79-94 Prof Dr. ALINA SKIRGIEŁŁO, 2006 Warszawa, with motivation of her 95th birthday Global warming and mycoflora in the Baltic Region HANNS KREISEL Zur Schwedenschanze 4, D 17498 Potthagen, [email protected] Kreisel H.: Global warming and mycoflora in the Baltic Region. Acta Mycol. 41 (1): 79 94, 2006. The author discusses possible effects of global warming on distribution and ecology of larger fungi, and presents examples of suggested indicator species which apparently are spreading from south to north. Only Basidiomycetes are corncerned, while actually no case of non lichenized Ascomycetes is known. A continued monitoring of the mentioned species is recommended. Key words: mycoflora, Basidiomycetes, global warming, Baltic Region INTRODUCTION Global warming (climatic change) with its consequences for weather and local climate, rising sea level, retreat of glaciers and of polar ice calottes, and subsequent nature catastrophes, actually is much disputed in newspapers, journals, and book publications. Highly reputed specialists of climatology, oceanography, or physics, have investigated the phenomena (e. g. Rahmstorf, Schellnhuber 2006). Since the end of last Ice Age, some 15 000 years ago, climate in central and northern Europe is warming, and enormous ice calottes have retired from this re- gion, making possible a re-settelement of large areas by vegetation and fauna. This process was not continuous, but interrupted by phases of standstill alternating with phases of further warming. Nevertheless, the actual phase of relatively fast warming is regarded as man-made to a large extent, and therefore requires special attention by scientists. Also in mycology, we are contemporary witnesses of changes in distribution and ecology of fungi, and we should use the chance to observe and describe the corre- sponding evolutions.

1975 USDA Forest Service General Technical Report PNW -36 115 PROPERTY OF: CASCADE HEAD EXPERIMENTAL FOREST AND SCENIC RESEARCH AREA OTIS, OREGON PACIFIC NORTHWEST FOREST AND RANGE EXPERIMENT STATION Ii S nF PARTMENT OF AGRICULTURE FOREST SERVICE ABSTRACT Insects that feed on fungi are primary dispersal agents for many beneficial and pathogenic species. Nearly 300 references on the subject, published since the mid-19th century are listed in this bibliography. Keywords: Bibliography, insect vectors, mycophagy, spores. ABOUT THE AUTHOR Robert Fogel is research assistant with Department of Botany and Plant Pathology, Oregon State University, Corvallis, and collaborator with the Pacific Northwest Forest and Range Experiment Station. For well over a century, certain insects have been known to feed on fungal fruiting bodies. Spore-eating insects have been presumed to be vectors of the fungi eaten. Only recently, however, have spores been demonstrated to remain viable after passage through an insects digestive tract (Leach et al. 1934, Nuorteva and Laine 1972). These works have reawakened interest in the role of insect mycophagy in dissemination of pathogenic, mycorrhizal, and other fungi. References in this bibliography are intended to provide an entry into the insect mycophagy literature. For brevity, most papers cited by earlier reviewers are not listed individually in this bibliography; i.e., papers cited by Hingley (1971), Benick (1952), Graham (1967), Weber (1972b), and Weiss (1921). The few references that I could not personally verify are marked with an asterisk and are cited as found in secondary sources. The most frequently reported insect mycophagists are either Diptera, mainly Mycetophilidae or Phoridae, and Coleoptera, separable into bark beetles and other beetles.

En Studie öfver mossornas vaiidringssätt och dess inflytande pa frâgan om reliktfloror. — Acta Soc. pro fauna et flora Fennica t. III, n. I. — ii2 pag. 80. — Helsingfors 1886. Es wurde bisher allgemein angenommen, dass die Moose (wie andere Kryptogamen) ihrer kleinen leichten Sporen wegen ohne Schwierigkeit auf einmal durch Wind über große Strecken hin fortgeführt werden können. Ref. hat sich (Engler's Jahrbücher II, p. 40) gegen diese Meinung ausgesprochen und freut sich nun, seine Ansicht durch die vorliegende interessante Arbeit des ausgezeichneten Pflanzengeographen Finnlands be- kräftigt zu sehen. Verfasser beginnt mit einem Citate aus Wallace »Island Life«, wo die allgemeine Anschauung, dass Kryptogamen leicht über große Strecken wandern, hervor- gehoben wird. Er unterwirft nun diese Ansicht einer näheren Prüfung , indem er die Verbreitung der Moose im Lappmark von Kemi und im nördlichen Österbotten unter- sucht. Die Moossporen sind kleinerund leichter, als die vulkanischen Aschenteilchen, über deren weite Verbreitung durch Luftströmungen kein Zweifel waltet. Die Brutzellen und Rhizoiden der Moose können durch Flüsse über lange Strecken transportirt und an den Ufern, fern vom ursprünglichen Standorte wieder abgesetzt werden. Man sollte deshalb geneigt sein anzunehmen, dass Moose leicht über große Strecken hinweg wandern. Es giebt auch viele Moose, die eine sehr zerstreute Verbreitung zeigen. Verfasser nennt aus dem von ihm untersuchten Gebiete Beispiele, wo die verschiedenen Standorte einer und derselben Art mehrere hundert Kilometer von einander entfernt liegen. Untersucht man aber die Sache näher, dann zeigt es sich, dass selbst unter den Moosen plötzliche Wanderungen über große Strecken jedenfalls zu den sehr seltenen Aus- nahmen gehören.
