Fungi developing on dung samples, from a wide range of locations and incubated in moist chambers, were recorded. Highly significant differences were found. Animal dung, and especially that of herbivorous mammals, bears a large number of fungi that are adapted to their specialized substratum. Various adaptations.

Since perithecia are very small and immersed, except for the erumpent neck and ostiole, Phomatospora spp. Samples were examined frequently, at intervals of a few days, with a x magnification stereomicroscope.
In other projects Wikimedia Commons. A widespread but overlooked species, recorded from Peru in Van Brummelen, Care was taken to ensure that cultures were not too wet.
Ascospores seriate, The fruiting bodies of the fungi then grow from the animal feces. Fruiting bodies were removed and mounted in water for examination at higher magnification. Mycological Research, in press Van Brummelen, J. Retrieved 30 March Thirty-two species of coprophilous fungi were recorded from seven dung samples collected from the state of Matto Grosso do Sul, Brazil, and incubated in moist chambers.
Fruiting bodies of Pilobolus will suddenly rupture, sending the contents over 2 metres away. March 14, ; Accepted: Most were dry when fungl, and were placed in paper envelopes. The spores themselves survive digestion by being particularly thick-walled, allowing them to germinate in the dung with minimum competition from other organisms. Retrieved from ” https: Some spores had a single basal cooprophilous appendage at the tip of the primary appendage, but other spores coprophikous seen with short secondary appendages that appeared to be attached laterally to the primary appendage.
Coprophilous fungi from Brazil
To provide a confident estimate of species richness a minimum sample size of is recommended, and estimates based on smaller subsets may give a less accurate value Richardson, Funig not all coprophilous fungi produce mushrooms, there are many that do, particularly in the genera CoprinopsisPanaeolus and Deconica.
Selected material annotated M in the records below has been placed in the Herbarium of the Royal Botanic Garden, Edinburgh. The mean species richness of These records, although based coprophilkus a very small number of samples, point to the high diversity of Brazilian coprophilic fungi.
Niessl One of a small group of species copropilous has spores with four apical secondary appendages. Limited material of a large-spored species that could not be named.
Samples were rehydrated and incubated on 1 August on moist paper towelling in plastic boxes with lightly fitting transparent lids, under ambient light and at room temperature ca o C. Spore mass x 9.
Stroma dark brown-blackish, thinly clavate, 8. Coprophiolus of interest in these observations are the relative abundance of Saccobolus species in contrast to the scarcity of Ascobolusa ratio of 4.
Secondary appendages difficult to see, either in the ascus or on free spores, but the short simple apical appendage had a fibrillose appearance, rather like the illustration of P.

Traverso Perithecial necks with asymmetrically arranged tapering tufts of setae, composed of fascicles of non-inflated hyphae. The seven samples provided a total of 75 records of 32 species. Mycological Papers, Ascomycetes, coprophilous fungi, diversity, species richness.
Boedijn The particular feature of this fungus is its large spores, which have two pigmented cells Fungi by adaptation Coprophagous organisms.
Coprophilous fungi release their spores to the surrounding vegetation, which is then eaten by herbivores. The spores then remain in the animal as the plants are digestedpass through the animal’s intestines and are finally defecated.
Spores obliquely uniseriate, hyaline, ellipsoid, Lundqvist and Van Brummelenin their monographic treatments of the Sordariaceae and Ascobolus and Saccobolusnoted some early records but, apart from the collections of Andre de Meijer personal communication and Jahnthere seem to be few recent records of coprophilous fungi from Brazil.
Spores are biseriate, x Brazilian Archives of Biology and Technology. Lanatuliwith a veil of long-celled inflated hyphae.
Superficially like a large C. Australian National Botanic Gardens. Samples were generally of similar size, with incubation chambers 10 x 7 cm, which would accommodate approx. Samples were collected on 6 and 9 July Table 1. Spores in a 4 x 2 arrangement when young sect. Paraphyses hyaline, very slightly clavate.
This is the commonest, most widespread and most variable species of Saccobolus. That study used cumulative species curves to compare the species richness of an area or substrate by calculating the number of species expected to be recorded from a standard number 50 of samples of dung. Samples were incubated for up to10 wk, with observations continuing whilst new fungi were being observed.
