Abstract: Recent work on the isolation of pathogenic fungi, including dermato? phytes, has been briefly reviewed in a previous paper (4). In the course of investigating a series of samples of soil for the presence of keratino? philic fungi, a new species of Trichophyton has been encountered. It was isolated from two different samples of soil by a technique described by Vanbreuseghem (8) and modified by Ajello (1).

TL;DR: Until recently, no species of Piptocephalis had been found to parasitize any fungus outside the Mucorales, but Dobbs and English (1954) described and named a new species, P. xenophila, which not only parasitizes certain species of Ascomycetes and Fungi Imperfecti, but grows and sporulates better on these hosts than on some species of MucOrales.

TL;DR: It is reported that plus and minus strains of Choanephora cucurbitarum were capable of forming zygospores when grown together in liquid medium in shaken flasks, and yields of 960 t/g/g of 8-carotene in dry mycelium were found.
Abstract: Barnett, Lilly and Krause (1) reported that plus and minus strains of Choanephora cucurbitarum were capable of forming zygospores when grown together in liquid medium in shaken flasks. At the same time yields of 960 t/g/g of 8-carotene in dry mycelium were found. Numerous mating types of members of the Choanephoraceae were available in our Culture Collection including C. cucurbitarum, C. trispora (Blakeslea trispora), C. conjuncta and Blakeslea circinans; therefore, a study was made in which opposite mating types were grown singly and paired in liquid synthetic mucor medium (SMM) in shaken flasks. This medium is composed of glucose 40 g, asparagine 2 g, KH2PO4 0.5 g, MgSO4 0.25 g, thiamine 0.5 mg and 1 liter of distilled water. Five hundred-ml flasks containing 100 ml of this sterile medium or 100 ml of the medium used for sporulation of this family were inoculated with C. cucurbitarum strains NRRL A-6097 and NRRL A-6098 singly and paired. Portions of vegetative mycelium were used as inoculum. The flasks were placed on a rotary shaker and incubated for 72 hours at 28° C. At the end of the fermentation each strain grown singly resulted in masses of almost white-colored mycelium. However, in the flasks inoculated with + and strains, the sporulation medium showed dark areas of zygospores while the vegetative mycelium was cream to

TL;DR: The genus Volvariella is a sharply circumscribed group of agaric species characterized macroscopically by possessing pink spores, free lamellae, and a stipe which bears no annulus but is encased at the base by a volva.
Abstract: Volvariella is a sharply circumscribed group of agaric species characterized macroscopically by possessing pink spores, free lamellae, and a stipe which bears no annulus but is encased at the base by a volva. The genus is widely distributed; species have been reported from tropical, subtropical, and temperate regions of both the eastern and the western hemispheres. More than one hundred species, subspecies, and varieties, which today would be considered to belong in Volvariella, have been described from throughout the world. Eighteen species are here recognized for North America. Lloyd (1898, 1899a, 1899b, under the name Volvaria) and Murrill (1917, under the name Volvariopsis) were the last to treat the North American species of the genus, but Kauffman (1918, under the name Volvaria) and Coker (1947, under the name Volvaria) published keys to and descriptions of the species occurring in Michigan and North Carolina, respectively.

TL;DR: It is found that during a recent investigation of the position of meiosis in the Myxomycetes, abundant material was available for a study of the development of the capillitia of Stemonitis, Comatricha, and Lamproderma.
Abstract: In view of the recent interest in the morphogenesis of simple organisms, it is surprising that so little attention has been given to the development of the fructifications of the Myxomycetes. In 1884 de Bary presented a review of the knowledge of sporangial formation up to that time, and since then there have been very few investigations on the development of myxomycete sporangia. Only one of these later investigations has been on a member of the Stemonitaceae, that of Bisby in 1914. During a recent investigation of the position of meiosis in the Myxomycetes (Wilson and Ross, 1955), abundant material was available for a study of the development of the capillitia of Stemonitis, Comatricha, and Lamproderma.
TL;DR: Since publishing the Index, eleven new Helicosporae and several new distribution records have come to my attention and Glen-Bott adds three new species to the genus Helicodendron, making it unnecessary, I feel, to include them here.
Abstract: Since publishing the Index (6), eleven new Helicosporae and several new distribution records have come to my attention. Glen-Bott (3) adds three new species to the genus Helicodendron. She includes in her paper a key to the hyaline and subhyaline species, in which the primary separations are based on characteristics of these fungi when grown on malt agar. She presents morphological descriptions of all but one of these, making it unnecessary, I feel, to include them here. Of the remaining eight species, four are from the literature and four are reported

Abstract: In his treatment of Merulius, Burt (1917), following Fries (1821), divided the genus into the Leptospori with white spores, and Coniophori with "ferruginous, ochraceous or only very slightly colored spores." Other workers, from the time of S. F. Gray (1821) to the present, have considered most of the members of the second group as belonging to a different genus based on spore color, rather than to the same genus based on hymenial configuration. Gray called this genus, after Persoon, Serpula. Patouillard (1897) called it Gyrophana, revising his earlier Gyrophora which was preoccupied by a lichen genus. In studying sev? eral series of specimens of Merulius (in the sense of Fries and of Burt), the author came to the conclusion, expressed in an earlier paper (1943), that there are two distinct series of species represented. Merulius, based on M. tremellosus Schrad. ex Fr., would include the species with hyaline to slightly colored spores, while Serpula Pers. ex S. F. Gray, based on S. lacrimans Pers. ex S. F. Gray, would include species with dark col? ored spores. It appears that the species assigned to Merulius represent a series derived from some Corticium-like ancestor with M. tremellosus and M. rubellus as the most elaborate members of the series, while spe? cies assigned to Serpula represent a series derived from some Coniophora-like ancestor with S\ lacrimans as the most specialized member of the series.

TL;DR: The present report is the first record of the isolation of dermatophytes from the atmosphere and one of the two caves from the soil of which T. mentagrophytes was isolated is Johnson's Pothole.
Abstract: The first report of a dermatophyte growing saprophytically in nature was that of Szathmary (11) in 1936. He isolated Trichophyton terrestre primum (T. gypseum) from the mud of watercourses in the park of the University of Peco. One year later Muende et al. (10) found a colony of Trochophyton growing on horse dung. Since then Micro? sporum gypseum has been recovered from soil by Gorden et al. (7), Gordon (6), Ajello (1, 2), Durie et al. (4), Fuentes et al. (5), Lurie et al. (8) and Mandels et al. (9). In 1954 Ajello et al. (3) isolated T. mentagrophytes and T. rubrum from shoes which had been stored for 1 to 4 weeks and Epidermophyton floccosum from shoes recently worn by a sufferer from tinea pedis. In 1955 Lurie et al. (8), while investigating the cause of "Cave Disease," isolated Trichophyton mentagrophytes from the soil of caves. We believe that the present report is the first record of the isolation of dermatophytes from the atmosphere. One of the two caves from the soil of which T. mentagrophytes was isolated is Johnson's Pothole. This cave is completely uninhabited ex? cept for occasional visits by spelaeologists. A total of 42 animals, including monkeys, rabbits, guinea pigs, rats and mice, was taken into the cave to a depth of about 90 feet where they were left for about 5 hours, during which time a heavy dust was raised by the activity of the spelaeologists. The animals were then brought back to the laboratory where they were kept under observation. The rectal temperature of the larger animals was taken daily. Some of the animals were killed after 6 days and further batches every 2 or 3 days thereafter. Their lungs were removed under sterile conditions; portions were fixed in formalin and sectioned; small fragments were planted on dextrose agar and actidione medium; other portions were macerated by grinding gently with sterile, washed, river sand and suspended in normal saline. After allowing the sand to sediment, the supernatant fluid was planted on the same media and also injected intraperitoneally into 6 mice. Half of these mice were killed after 3 weeks and half after 6 weeks. Their livers and spleens were removed under sterile conditions. Portions were fixed in formalin and sectioned and portions were macerated and planted on dextrose agar and actidione medium.
