Herpomyces Gracilis
''Herpomyces'' is a fungal genus in the order Herpomycetales (Laboulbeniomycetes), with species that are exclusively ectoparasites of members of the Blattodea order (cockroaches). As of 2020, 27 species of ''Herpomyces'' are formally described. Members of ''Herpomyces'' have been reported from all continents except Antarctica.

Periplaneta Americana
The american cockroach (''Periplaneta americana'') is the largest species of common cockroach, and often considered a pest. In certain regions of the U.S. it is colloquially known as the waterbug, though it is not a true waterbug since it is not aquatic. It is also known as the ship cockroach, kakerlac, and Bombay canary. It is often misidentified as a palmetto bug. Despite their name, American cockroaches are native to Africa and the Middle East. They are believed to have been introduced to the Americas only from the 17th century AD onward as a result of human commercial patterns, including the Atlantic slave trade The Atlantic slave trade, transatlantic slave trade, or Euro-American slave trade involved the transportation by slave traders of enslaved African people, mainly to the Americas. The slave trade regularly used the triangular trade route and i .... Distribution Despite the name, none of the ''Periplaneta'' species is native to the Americas; ''P. americana'' ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomyce ...

Laboulbeniomycetes
The Laboulbeniomycetes are a unique group of fungi that are obligatorily associated with arthropods, either as external parasites ( Herpomycetales and Laboulbeniales) or for dispersal ( Pyxidiophorales). Herpomycetales and Laboulbeniales fungi are minute; their fruiting bodies, referred to as ''thalli'', commonly measure less than one millimeter. They live on the antennae, the mouthparts or other body regions of their arthropod hosts. Although several species of Laboulbeniomycetes have more or less extensive, root-like hyphal systems (haustoria In botany and mycology, a haustorium (plural haustoria) is a rootlike structure that grows into or around another structure to absorb water or nutrients. For example, in mistletoe or members of the broomrape family, the structure penetrates th ...) inside their hosts, as a group these fungi are relatively harmless to their hosts. These fungi occur usually only on adult hosts; apparently immature arthropods eliminate them during e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herpomycetales
The Herpomycetales is an order of fungi within the class Laboulbeniomycetes. The order includes a single dioecious genus, '' Herpomyces'', with 27 accepted species of obligate ectoparasites that are associated exclusively with cockroaches. Like the Laboulbeniales order, they produce cellular thalli. However, the thalli of ''Herpomyces'' are developmentally and morphologically unique. The order was described in 2019 based on the phylogenetic analysis of three gene regions. A more recent phylogeny found that Herpomycetales and Laboulbeniales are not sister clades, which provides evidence for the idea that the thallus originated at least twice in the class Laboulbeniomycetes. This is in line with the fact that thalli of both orders are developmentally and morphologically different. The draft genome of '' Herpomyces periplanetae'' has been sequenced and assembled—the only one in the class thus far. ''Herpomyces periplanetae'' is a very widespread parasite on the antennae of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Herpomycetaceae are a family of fungi in the order Laboulbeniales. Taxa have a widespread distribution, and are ectoparasitic or epibiotic on cockroaches (family ''Blattidae Blattidae is a cockroach family in the order Blattodea containing several of the most common household cockroaches.

Roland Thaxter
Roland Thaxter (August 28, 1858 – April 22, 1932) was an American mycologist, plant pathologist, botanist, and entomologist, renowned for his contribution to the insect parasitic fungi—Laboulbeniales. His college education was completed at Harvard, where he dedicated forty years to mycological and botanical research. His five-volume series on fungi in the order Laboulbeniales laid a solid foundation of research on these insect ectoparasites. He also contributed to the field of Plant Pathology. Biography Roland Thaxter was born in Newtonville, Massachusetts, 1858, the third and youngest child in the family. His parents were Levi Thaxter and Celia Thaxter, Celia (née Laighton) Thaxter. He married Mabel Gray Thaxter in 1887. Thaxter's personality was influenced greatly by his literary family. His father was a lawyer and an authority who brought the works of the poet Robert Browning to the American public. His mother, Celia Thaxter, was a distinguished poet, most well known for he ...

Ectoparasite
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blattodea
Blattodea is an order of insects that contains cockroaches and termites. Formerly, termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests they evolved from within the cockroach lineage, cladistically making them cockroaches as well. The Blattodea and the mantis (order Mantodea) are now all considered part of the superorder Dictyoptera. Blattodea includes approximately 4,400 species of cockroach in almost 500 genera, and about 3,000 species of termite in around 300 genera. Termites are pale-coloured, soft-bodied eusocial insects that live in colonies, whereas cockroaches are darker-coloured (often brown), sclerotized, segmented insects. Within the colony, termites have a caste system, with a pair of mature reproductives, the king and the queen, and numerous sterile workers and soldiers. Cockroaches are not colonial but do have a tendency to aggregate and may be considered pre-social, as all adults are capable of breeding. Other simil ...
