Walter Gams

Austrian/dutch mycologist (1934–2017).

Konrad Walter Gams (9 August 1934 – 9 April 2017) was an Austrian mycologist. He worked as a scientist for his entire career at the Centraalbureau voor Schimmelcultures (Westerdijk Fungal Biodiversity Institute) in the Netherlands. He served in the international authority on classification of fungi, the Special Committee on Fungi and Lichens (renamed Nomenclatural Committee for Fungi), from which he contributed to the development of the International Code of Nomenclature for algae, fungi and plants. Some species of fungi he identified became sources of pharmaceutical drugs such as cephalospori

Clonostachys rosea (Gliocladium Roseum) (Link) Schroers, Samuels, Seifert & W. Gams 1999
fungi species in the bionectriaceae family
Clonostachys rosea f. rosea, also known as Gliocladium roseum and commonly called the rose bracket, is a species of fungus in the family Bionectriaceae. It colonizes living plants as an endophyte, digests material in soil as a saprophyte and is also known as a parasite of other fungi and of nematodes. It produces a wide range of volatile organic compounds which are toxic to organisms including other fungi, bacteria, and insects, and is of interest as a biological pest control agent.

This genus was first named and introduced by Rasoul Zare (IRIPP) and Walter Gams (CBS).
Tolypocladium W. Gams 1971
fungi genus in the ophiocordycipitaceae family
Tolypocladium is a genus of fungi within the family Ophiocordycipitaceae. It includes species that are parasites of other fungi, insect pathogens, rotifer pathogens and soil inhabiting species with uncertain ecological roles. Tolypocladium was originally circumscribed as a genus containing anamorphic fungi. It was later determined that some Cordyceps-like teleomorphic fungi were the teleomorphs of Tolypocladium species. These species were considered to belong in the genus Cordyceps until molecular phylogenetics studies found these species to be more closely related to Ophiocordyceps and were
Glomerellales Chadef. ex Réblová, W. Gams & Seifert 2011
fungi order in the class sordariomycetes
Glomerellales is an order of ascomycetous fungi within the subclass Hypocreomycetidae (Sordariomycetes). The order includes saprobes, endophytes and pathogens on plants, animals and other fungi with representatives found all over the world in varying habitats. Glomerellales members diagnostically present peritheciate ascomata with a 2-3 layered perithecial wall and a periphysate ostiolum. Paraphyses are tapered and thin-walled. The asci are unitunicate, 8-spored and inamyloid, and the apex is either thickened without visible discharge mechanism or thin-walled with a distinct annulus. Unlike

Lecanicillium longisporum (Petch) Zare & W. Gams 2001
fungi species in the cordycipitaceae family
Lecanicillium longisporum is the approved name of an entomopathogenic fungus species, that was previously widely known as Verticillium lecanii (Zimmerman) Viegas, but is now understood to be an anamorphic form in the Cordyceps group of genera in the Cordycipitaceae. It now appears that isolates formerly classified as V. lecanii could be L. attenuatum, L. lecanii, L. longisporum, L. muscarium or L. nodulosum. "V. lecanii" was first described in 1861 and has a worldwide distribution. Insects are infected when they come into contact with the sticky fungal spores which then grow and invade the

fungi species in the cordycipitaceae family
Engyodontium aranearum is a species of ascomycete fungus in the family Cordycipitaceae. It parasitizes the long bodied cellar spider (Pholcus phalangioides). It causes 100% mortality in infected spiders.
Tolypocladium inflatum W. Gams 1971
fungi species in the ophiocordycipitaceae family
Tolypocladium inflatum is an ascomycete fungus originally isolated from a Norwegian soil sample that, under certain conditions, produces the immunosuppressant drug ciclosporin. In its sexual stage (teleomorph) it is a parasite on scarab beetles. It forms a small, compound ascocarp that arises from the cadaver of its host beetle. In its asexual stage (anamorph) it is a white mold that grows on soil. It is much more commonly found in its asexual stage and this is the stage that was originally given the name Tolypocladium inflatum.
Sarocladium W. Gams & D. Hawksw. 1976
fungi genus
Sarocladium is a genus of saprotrophic fungi found in crops, soil, plant debris, and rotting mushrooms. It was created by Walter Gams and David Leslie Hawksworth for the species of rice fungus, Sarocladium oryzae, in 1976. The species are most notable as a causative pathogens of sheath rot of rice and blight in bamboo. Species like S. strictum can cause infection in humans called hyalohyphomycosis (skin, nail and tissue infection) that can lead to fatal disease if improperly treated.
Phialemonium obovatum W. Gams & McGinnis 1983
fungi species in the cephalothecaceae family
Phialemonium obovatum is a saprotrophic filamentous fungus able to cause opportunistic infections in humans with weakened immune systems. P. obovatum is widespread throughout the environment, occurring commonly in sewage, soil, air and water. Walter Gams and Michael McGinnis described the genus Phialemonium to accommodate species intermediate between the genera Acremonium and Phialophora. Currently, three species of Phialemonium are recognized of which P. obovatum is the only one to produce greenish colonies and obovate conidia. It has been investigated as one of several microfungi with
Metarhizium flavoviride W. Gams & Rozsypal 1973
fungi species in the clavicipitaceae family
Metarhizium flavoviride is a Sordariomycete in the order Hypocreales and family Clavicipitaceae. The genus Metarhizium currently consists of over 70 described species and are a group of fungal isolates that are known to be virulent against Hemiptera and some Coleoptera. M. flavoviride is described as its own species, but there also exists a variety of M. flavoviride, which is M. flavoviride var. flavoviride. Previously described varieties of M. flavoviride have been documented, however recent random amplified polymorphic DNA (RAPD) markers have assigned these varieties as new species. The
Diaporthe toxica P.M. Will., Highet, W. Gams & Sivasith. 1994
fungi species in the diaporthaceae family
Diaporthe toxica (anamorph Phomopsis sp. formerly P. leptostromiformis) is a fungal endophyte and occasionally a pathogen of Lupinus spp. The fungus produces secondary metabolites that result in toxicosis of animals such as lupinosis of sheep when infected lupins are ingested. These fungal mycotoxins known as phomopsins cause symptoms expressed as either a severe acute liver disease or as a chronic liver dysfunction syndrome. The discovery and naming of D. toxica concludes over a century of investigation into the cause of lupinosis since the first major outbreak in Germany in 1872. The
Aspergillus fischerianus (Aspergillus Fischeri) Samson & W. Gams 1986
fungi species in the aspergillaceae family
Aspergillus fischeri is a species of fungus in the genus Aspergillus. And is widely distribute in soil, grain and canned food world wide. In the other hand Aspergillus fischeri is a BSL-1 plant pathogen. About 64% of species in genus Aspergillus lack knowned sexual reproduction in their life cycle, causing them were classified into Fungi imperfecti before, producing the teleomorph name Neosartorya fischeri when the sexual reproduction were discovered. But after the abolish of the Fungi imperfecti nomenclature, Aspergillus which is the anamorph name of should be the holomorph name when we

Wardomyces moseri W. Gams 1995
fungi species in the microascaceae family
Wardomyces moseri is a species of mold in the family Microascaceae. It was described as new to science by Walter Gams in 1995. The specific epithet honours mycologist Meinhard Moser "on the occasion of his 70th birthday". The type locality was a riverbank in the savanna area east of Villavicencio, Colombia. The fungus was discovered growing on a dead petiole of moriche palm (Mauritia flexuosa). It differs from other Wardomyces by having conidia that are readily liberated.

Umbelopsis ramanniana (Möller) W. Gams 2003
fungi species in the umbelopsidaceae family
Umbelopsis ramanniana is a common and abundant soil fungus. Although the ecological role of this fungus in natural ecosystems is not yet known, it is a cosmopolitan saprotroph in soil, forest leaf litter, in animal dung, and on the spore-producing bodies of ascomycete fungi. Umbelopsis ramanniana has also been found growing as an endophyte within xylem tissue of both healthy and declining conifers, but its exact effect on the plant hosts is unknown. Umbelopsis ramanniana is a representative of a unique group of zygomycete fungi that is distinct from the Mucoromycotina and Mortierellomycotina
Sagenomella W. Gams 1978
fungi genus in the aspergillaceae family
Sagenomella is a genus of filamentous Ascomycota fungus that has reported to cause systemic illness in animals. The genus was circumscribed by Walter Gams in 1978. Sagenomella chlamydospora has been reported to cause a systemic illness in dogs. They are normally considered a non-dermatophytic fungi. Both skeletal and visceral phaeohyphomycosis due to granuloma formation have been reported, and iatrogenic infections associated with wound dehiscence is common. Clinical signs of Sagenomella spp. infections are often vague and most cases cited report sudden death as a consistent sign.

Phaeomoniella Crous & W. Gams 2000
fungi genus in the phaeomoniellaceae family
Phaeomoniella is a genus of hyphomycete fungi in the family Celotheliaceae. The genus was circumscribed by Pedro Crous and Walter Gams in 2000 to contain the type species, P. chlamydospora, the causal agent of Petro grapevine decline, a disesase in the esca disease complex. Phaeomoniella is similar to Phaeoacremonium, differing in cultural characteristics, and in the morphology of the conidiophores and conidia. The family Phaeomoniellaceae was proposed by Paul Kirk in 2015, using a reference to the description of the order Phaeomoniellales, circumscribed earlier that year. However, because
