Introduction
I’m a dung fungi mycologist interested in research on the ecology, taxonomy, and biology of dung-inhabiting fungi and myxomycetes, with a focus on understanding the role of these fungi (and like-fungi microorganisms) in ecosystem functioning. I’m a scientific communicator who spreads mycological science to the public, through the Mykocosmos Project, on social media, and through activities aimed at promoting science outreach.

Until recently, no native mushroom was considered food in the Cerrado biome, while there are records of the occurrence of about 638 species of fungi so far, many of which have numerous undefined potentials, with the potential for food among them. Our work presents the nutritional aspects of two mushroom species found in an agroforestry system in th...
Panaeolus sylvaticus is a saprotrophic, non-coprophilous, mushroom described in 2019 from material collected at two sites in western Paraná State, Southern Brazil. It was reported growing in decaying plant debris in seasonal semi-deciduous forest remnants. Although surveys of funga in southern Brazil, especially for Agaricales, have been intensivel...
We define copromycodiversity as all the morphological, physiological, functional, and ecological diversity of an assemblage of dung-inhabiting fungi, also known as coprophilous fungi. These fungi are represented by species of the phyla Ascomycota, Basidiomycota, and Mucoromycota in the sensu stricto of the Kingdom. Traditionally, other groups of or...
The Brazilian Cerrado is a biodiversity hotspot characterized by a mosaic of
phytophysiognomies and soil types. Arbuscular mycorrhizal fungi (AMF) are important components of biodiversity, participating in symbiotic relationships
with plants and involved in ecosystem functioning. Variations in the AMF
communities in Cerrado phytophysiognomies are n...
The phylum Basidiomycota represents one of the most diverse groups of fungi. In this phylum, the order Agaricales has great ecological and economic value. However, this order is little studied in Brazil. Thus, in an attempt to contribute to the scientific knowledge about this taxon, in this study we evaluated trends and gaps in scientific productio...
This conference poster highlight recent contributions to the knowledge of the coprophilous genus Poronia (Xylariaceae: Ascomycota) to Brazil, with new records and additions to its geographical extent for some species.
History records several expeditions motivated by the search for territories, food, natural resources, and even humans. These expeditions aroused the interest in nature and science in enthusiasts who set out on journeys to distant lands where they described their peoples and their habits, landscapes, species, and made collections of biological mater...
Science outreach has become a particularly important duty in shortening the knowledge gap between scientists and the public, in order to strengthen societal decision-making power in the global change crisis.

Recentemente propusemos o termo copromicodiversidade para definir o conjunto de fungos (lato sensu) que estão associados, em alguma etapa do ciclo de vida, às fezes animais, sobretudo de herbívoros, incluindo sua diversidade taxonômica, ecológica e fisiológica. Esses organismos desempenham papéis-chave nos ecossistemas terrestres, onde estão envolv...
Fungi are important in several aspects of human life. In particular, to agriculture, pathogenic fungi are of great importance, as they are responsible for production losses of the most diverse types. Because of this, knowledge about pathogenic fungus is of extreme importance for farmers and professionals working in agricultural areas. Among farmers...
Fimicolous organisms are those that can grow on dung. These substrates offer conditions that favour colonization by microorganisms, such as high nutrient and moisture content and an alkaline-neutral pH that is especially advantageous in arid/desertic regions. There are about 250 species of myxomycetes known from Brazil, which are distributed in all...
In 2014 we published the first checklist of fungi sensu lato recorded on dung from Brazil, as a result of an effort to maintain an easily accessible database on the knowledge of the diversity of these fungi. In the last 10 years there has been a significant increase in the number of publications involving this ecological group, and we are presentin...

Myxomycetes (Amoebozoa) can be found on a wide range of substrates and
among these, the dung of several animal species, primarily herbivorous, in
which case they are considered fimicolous. Dung can be a favourable substrate
for myxomycete due its relatively high content of water, nutrients and
microorganisms. Despite efforts to study fimicolous myx...

Scientific popularization publication on coprophilous fungi based on research conducted in Cerrado areas in Central Brazil.
Much of the diversity of mushrooms is still unknown to science. In the search for new edible mushrooms, we began to look at the traditions of Amazonian forest peoples in order to learn about the potential for edible mushrooms among other species. In particular, the Yanomami people launched the encyclopedia of food (Sanoma) in 2016 to preserve their...
The ways people get access to information are constantly in transition. With the Internet, a new world of possibilities was created, so the initial function of cellphones is, yet, to
make/receive calls? Do scientists publicize to other scientists or to all people?
In Brazil, we have good examples of divulgators. We need to turn ‘science makers’ int...

Hi there! I am interested in understanding (or making myself more confused, whatever) the evolutionary pathways of coprophilic habit in dung-inhabiting fungi. Taking into account the dung of herbivore animals as a substrate to dung fungi growth, we have few "candidates" to be dung-producers with some requirements to early dung fungi (e.g. the amphibians Ichthyostega (I don't know if it was an herbivore or omnivorous, appearing about ca. 375 million y/a in Devonian, once the first tetrapod herbivores made their first appearance in the fossil record near the Permio-Carboniferous boundary, ca. 300 million y/a.). Terrestrial plants made their first appearance ca. 450 million y/a, with a well-accepted role of arbuscular mycorrhizal fungi in this process. So, my question is about if there is some study dealing with the evolutive process of dung-inhabiting fungi, presenting some consideration where and how, in the evolutive process, this ecologic habit firstly appears? Any considerations are welcome! Thank you!
If you want to help me with this question with more details (or more questions ¯\_(ツ)_/¯ ) or papers/books, feel free to also send me an email at: calacafjs@gmail.com.
