Critical survey of medical mycology in Romanian People's Republic for the years 1952–1962

Critical survey of medical mycology in Romanian People's Republic for the years 1952–1962

A survey of small Egyptian mammals for pathogenic fungi.

In a mycological survey of small animals of the Egyptian Delta, hair, liver and spleen of 2064 apparently healthy animals were cultured. Trichophyton mentagrophytes was isolated 11 times from the house mouse (Mus musculus). Microsporum gypseum was isolated in four instances, once from the gerbil (Gerbillus gerbillus), once from the house rat (Rattus rattus), and twice from the Nile Grass rat (Arvicanthis nioticus). No recoveries of systemic fungi from the internal organs are reported.

An experimental study of tinea pedis and onychomycosis of the foot.

So much has been written about the subject of athlete's foot that one can hardly add still another paper to an already mountainous pile without some justification. We thought we could gain some fresh appreciation of this disease by studying it experimentally in a prison population. With this group it was possible to do a number of things which would otherwise have been rather difficult. Rigid control over the subjects, adult males in the age range of 20-50 years, offered many experimental advantages. Total Mycological Survey of the Foot The first part of the study had two objectives: (a) the setting up of reliable clinical criteria of infection; and (b) establishing correlations between interdigital, plantar, and nail infections on the same foot. Both feet of 100 consecutive subjects chosen without selection were examined; in each case particular attention was paid to the interdigital

Contributions to the Mycoflora of Bermuda: I

of the mycological survey of the islands, initiated by The New York Botanical Garden more than a quarter of a century ago, and continued intermittently to the present time. The first expedition, in connection with the above work, was made in the year 1912, covering almost exactly the same seasonal dates as our recent one. Thus the third visit represented a twentysixth anniversary of the first. At the time of the first visit scarcely more than a score of fungi were known from the islands, and the place had the reputation of being almost barren of this particular form of plant life. Consequently the voyage was undertaken with some misgivings. These fears, however, proved to be groundless for as a result of this first short visit, the number of known species of fungi was increased to considerably more than a hundred, a list of which was published in the Memoirs of The New York Botanical Garden in August, 1916, and constituted the first extensive list published of the fungi of the islands. A few new species were included. The results of the second expedition, in company with Professor H. H. Whetzel, are left out of consideration since most of the material collected on this occasion (1926) is in Cornell University, and for the most part unworked. The remoteness of these islands, together with the fact that they have apparently never been connected with any other existing body of land, adds interest to the study of their land flora. Although the fungi cannot be said to be abundant, on critical study one is impressed first by the number of species found there which are not known to occur in other parts of the world, although we do not usually think of the fungi as being restricted to very limited

Historical Survey of Mycology

UNLIKE the treatment of flowering plants, so far as Linnaeus was concerned, the subject of mycology had scarcely begun before his time. It is true that many fungi were mentioned by the classical writers but most of the interest in them was derived solely from their gastronomic effects. Their origin puzzled certain writers who regarded them as the result of the fermentation of the earth; truffles, on the other hand, were supposed to be due to the action of lightning. Herbals were based on classical authority: in 1593 Cesalpino wrote suggesting that fungi were not plants and were spontaneously generated.

A Fungus on Lace Bugs

In March of 1935 specimens of lace bugs (Leptopharsa Heveae Drake & Poor) on Hevea brasiliensis from Para, Brazil, were sent by Dr. C. H. T. Townsend through the Bureau of Entomology and Plant Quarantine to the Division of Mycology and Disease Survey, of the Bureau of Plant Industry, for the determination of a fungus thought to be parasitic on the insects. Observations made by Dr. Townsend indicated that the fungus had been fairly effective in controlling the lace bug which had been causing some concern as a rubber plant pest. He stated that a considerable percentage of the immature stages of the insect had been attacked and killed. Later, Dr. J. R. Weir sent additional specimens of the same insects attacked by this fungus, with the information that the fungus had practically destroyed the bugs over wide areas in certain of the localities where rubber plantings had been made. Additional specimens have been received from time to time from Dr. Weir who has made extensive field observations.

Notes on New Species of Ustilaginales

The descriptions of the following ten new species and one new combination are based on specimens sent to the author by members of the Union Department of Agriculture, Pretoria, Union of South Africa, and by Ross W. Davidson of the office of Mycology and Disease Survey, United States Department of Agriculture. The specimens from the United States Depart? ment of Agriculture are from collections made by Mrs. Agnes Chase in Brazil and she has determined all hosts originating from Brazil.

PHYTOPATHOLOGICAL SURVEY OF SANTO DOMINGO, 1925-1929

This comprises a list of the most important diseases from the economic point of view, which affect cultivated plants in Santo Domingo, with brief notes on their importance and distribution, as well as the most widely distributed diseases of little economic importance and also those of marked scientific interest. In a very general way, mention is also made of a number of experiments that were made, some of which have been reported and others are in the course of publication. We also touch briefly on different diseases which are new or almost unknown. Following a short introduction aiming to enumerate the previous phytopathological and mycological surveys and a brief statement regarding the agricultural production of Santo Domingo and the different agricultural zones of the Republic, we discuss 53 cultivated plants, affected by 175 diseases of which 122 are presumably or definitely ascribed to fungi, 33 to non-parasitic causes, virus or unknown causes, 13 to Schizomycetes, 3 to Algae, and 3 to parasitic Phanerogams. The total number of fungi reported totals 151, in addition to which 13 insects are cited among those of greater interest. A more complete study is made of the principal plants of the Republic from the economic standpoint namely sugar cane, cacao and coffee.

A Mycological Survey of Porto Rico and the Virgin Islands

During the Spanish occupation of Porto Rico practically no attention was given to the rich fungous flora of the island. Only two collections of fungi were made, and they were small and relatively unimportant. After Porto Rico was annexed by the United States the Insular Department of Agriculture undertook various mycological investigations and incidentally initiated a fungous survey. Between 1900and the present a number of Amer? ican botanists, interested in collecting, have visited the island, and several native Porto Rican botanists with training in taxo? nomic mycology have cooperated with them. In the aggregate a very considerable number of fungi have been collected, and dis? tinct contributions toward a knowledge of various groups have been made. The fungi of Porto Rico are known now probably better than those of any other area of equal size in the American tropics. The mycological survey of Porto Rico and the Virgin Islands which recently has been published by Seaver and Chardon * is a compilation based chiefly on previously published papers, and constitutes an annotated check-list of the known fungi of these Islands. The fungi of the Virgin Islands have been less exten? sively studied than those of Porto Rico, and are known chiefly from Seaver's collections made in 1923. The survey on the whole is surprisingly complete, and the paper will be of great service to all students of tropical fungi. The material is arranged on the basis of the classification of the fungi, the genera of a
