TL;DR: Among 464 bacteria, l-Asparaginase and l-glutaminase activity was detected in many microorganisms and the distribution of these activities was found to be related to the classification of micro-organisms as mentioned in this paper.
Abstract: Summary: l-Asparaginase and l-glutaminase activities were detected in many microorganisms and the distribution of these activities was found to be related to the classification of micro-organisms.
Among 464 bacteria, the activities occurred in many Gram-negative bacteria and in a few Gram-positive bacteria. Most members of the family Enterobacteri-aceae possessed l-asparaginase. l-Asparaginase and l-glutaminase occurred together in a large proportion of pseudomonads. Among Gram-positive bacteria many strains of Bacillus pumilus showed strong l-asparaginase activity. Amidase activities were also observed in several strains in other families.
l-Asparaginase activity was not detected in culture filtrates of 261 strains of species of the genera Streptomyces and Nocardia, but l-asparaginase and l-glutaminase were detected when these organisms were sonicated.
The amidase activities in culture filtrates of 4158 fungal strains were tested. All the strains of Fusarium species formed l-asparaginase. Organisms of the genera Hypomyces and Nectria, which are regarded as the perfect stage of the genus Fusarium, also formed l-asparaginase. Several Penicillium species formed l-asparaginase. Two organisms of the family Moniliaceae formed l-glutaminase together with l-asparaginase, and a fewascomycetous fungi formed l-asparaginase or l-glutaminase.
Among 1326 yeasts, l-asparaginase or l-glutaminase occurred frequently in certain serological groups of yeasts: VI (Hansenula) group, Cryptococcus group and Rhodotorula group. Many strains of Sporobolomyces species also showed l-asparaginase activity. Several strains of Cryptococcus and Rhodotorula group possessed l-glutaminase and l-asparaginase. l-Glutaminase alone was formed in many strains of Candida scottii and Cryptococcus albidus, both of which are related to Basidiomycetes.

TL;DR: One who is confronted with the task of identifying a member of section Martiella must compare his fungus with the two genera, five species, ten varieties and four forms established in the above (and only) taxonomic treatment heretofore available for this section.
Abstract: THE PLANT pathologist and mycologist are confronted continually with the problem of identifying the widely distributed members of the genus Fusarium, so frequently associated with the disorders of plants. Among the Fusaria most frequently found in such associations, some as virulent parasites and some as saprophytes, are the three species, seven varieties and three forms grouped by Wollenweber and Reinking (1935) into the section Martiella of this genus. In addition to these imperfect fungi, two species of Hypomyces, with their three varieties and one form, are included in the section. Therefore, one who is confronted with the task of identifying a member of section Martiella must compare his fungus with the two genera, five species, ten varieties and four forms established in the above (and only) taxonomic treatment heretofore available for this section. Wollenweber and Reinking distinguish F. coeruleum (Lib.) Sacc. from the other two Fusarium species, F. solani (Mart.) App. et Wr. and F. javanicum Koord., on the basis of a relatively slight difference in the degree of curvature at the base of the macroconidia. F. solani is distinguished from F. Javanicum by the width of 3to 5-septate conidia, which is 5 to 6 microns in the former and 4 to 5 microns in the latter species. However, varieties of F. solani are listed which have widths between 4 and 5 microns. Further differentiation between these species is based on spore length, colony appearance and pigmentation, and the relative bluntness of the apical cell. The average dimensions of the 3and 5-septate conidia of the three Fusariurm species of the section are as follows:

TL;DR: A new species of Hypomyces pseudolactifluorum is described, characterised by semi-immersed to immersed perithecia and fusiform, apiculate and verrucose ascospores.
Abstract: Background Hypomyces is a large genus of fungicolous fungi, parasitising the fruiting bodies of Agaricales, Boletales, Helotiales, Pezizales and Polyporales. Hypomyces currently comprises of 147 species widely distributed in Australia, China, France, Germany, Italy, Japan, North America, Sri Lanka, Thailand and UK. Amongst them, 28 species have been recorded in China. New information Hypomyces pseudolactifluorum sp. nov., growing on the fruiting bodies of Russula sp. in subsect. Lactarioideae and collected from Yunnan, China, is described with illustrations and molecular phylogenetic data (combined ITS, LSU, TEF1-α and RPB2 sequence dataset). The new species is characterised by semi-immersed to immersed perithecia and fusiform, apiculate and verrucose ascospores. We also review the species diversity of the genus Hypomyces in China.

TL;DR: The genus Cladobotryum Nees is characterized by mostly verticillately branched conidiophores with phialides, dry, one-celled or pluricellular conidia in heads or irregular chains, and plurICEllular chlamydospores or sclerotia.
Abstract: The genus Cladobotryum Nees is characterized by mostly verticillately branched conidiophores with phialides, dry, one-celled or pluricellular conidia in heads or irregular chains, and pluricellular chlamydospores or sclerotia. Eight species are considered. In four of them the corresponding Hypomyces state is known, in one species it is conjectured. In cultures of Hypomyces rosellus and H. odoratus perithecia were obtained after mating of compatible strains. The conidium-forming cells are interpreted as phialides in all species, even if the meristematic zone extends beyond the apex and surrounds itself with a secondary wall.
