TL;DR: Emmonsiella capsulata, the perfect state of Histoplasma capsulatim, is differentiated from other genera of Gymnoascaceae by the formation of tight coils radially arising from the ascogonium and by sinuately branched, anastomosed peridial hyphae that arise laterally from these coils.
Abstract: Emmonsiella capsulata, the perfect state of Histoplasma capsulatim, is differentiated from other genera of Gymnoascaceae by the formation of tight coils radially arising from the ascogonium and by sinuately branched, anastomosed peridial hyphae that arise laterally from these coils. Emmonsiella capsulata is heterothallic with two mating types. Isolates from soil and those of human origin mate successfully, indicating their genetic compatibility.
TL;DR: Pure cultures were obtained and the cultural and microscopic characteristics agreed with those described for P. sulphureus (2), and it was found that the hyphae were thin-walled, aseptate, and lacked clamp connections and conidia.

TL;DR: In D. disciformis the sporangia are small, and the spores are purple-brown in mass, 11-13 p/ in diam, minutely but densely warted and usually reticulate, and in D. vaccinum they are larger and sparsely warted without any tendency for the warts to be arranged in a reticulum.

TL;DR: Thermophilic fungi isolated from partially decomposed vegetation from the interior of a recently used alligator nest suggest that habitats suitable for the origin and evolutionary survival of obligately thermophile fungi have existed for long periods of time.
Abstract: Thermophilic fungi isolated from partially decomposed vegetation from the interior of a recently used alligator (Alligator mississipiensis) nest included Chaetomium thermophile var. coprophile Cooney & Emerson, C. thermophile var. dissitum Cooney & Emerson, Humicola lanuginosa (Griffon & Maublanc) Bunce, Talaromyces thermophilus Stolk, and Thermoascus aurantiacus Miehe sensu Apinis. The thermotolerant fungi Aspergillus fumigatus Fresenius and Burgoa-Papulaspora sp. were also isolated. The ontogeny of bulbils of the latter isolate is described. Alligator nesting material provides a habitat suitable for the thermophilic fungi, where the heat required for growth of these fungi is not provided by the body heat of the nest builder. These data suggest that habitats suitable for the origin and evolutionary survival of obligately thermophilic fungi have existed for long periods of time.
TL;DR: Mycelia which had suffered graduated degrees of injury were subjected to a series of abrupt nutritional transfers, and it was found that the fruiting response to nutrient shifts depended qualitatively on the extent of the injury, but could be independent therefrom.
Abstract: The present paper reports the results of investigations concerning a number of mutually interacting factors that affect the fruiting response of haploid mycelia of S. commune to mechanical injury. ...
TL;DR: Criteria for nomenclature of spore states in the Uredinales should relate to their positions in the life cycle and be based on their nuclear conditions and this system reflects the function of each spore state.
Abstract: SUMMARY The criteria for nomenclature of spore states in the Uredinales should relate to their positions in the life cycle and be based on their nuclear conditions. Definitions for five spore states are presented based on these criteria. This system reflects the function of each spore state. On the other hand, naming of the spore states based only on the external morphology is not only impossible because of morphological variability but illogical and creates confusion. Logically, names of the spore states should be based on their true nature and the use of morphological terms should be restricted to the description of spores and spore-producing structures. Terminology for the spore states of the rust fungi was proposed by de Bary, Tulasne and others in the middle of the last century and modified by Arthur (1905, 1925, 1934), Azbukina (1970), Cummins (1959), Cunningham (1930, 1931), Laundon (1967a), Savile (1968), and others. Several names have been proposed for each spore state, such as spermatia, pycnidiospores, pycniospores; aeciospores, aecidiospores; uredospores, urediniospores, urediospores; teliospores, teleutospores; sporidia or basidiospores. I use spermatia, aeciospores, urediniospores, teliospores and basidiospores without critical considerations of etymology or historical background. Not only several different terms are used for one spore state but two different bases are applied in the definition and terminology of spore states and, in certain cases, the same spore state has been interpreted differently and called by different names. The differences in definition and interpretation have been reflected in the classification and nomenclature of some taxa. The two different systems can be called the "ontogenic system" and the "morphologic system." Current uredinologists use one or the other system or mix the two, either consciously or unconsciously, in their 1 Based in part on a paper presented in the symposium on "Criteria and classi
