Extract from Wikipedia article: Phycomyces blakesleeanus is a filamentous fungus in the Order Mucorales of the phylum Zygomycota or subphylum Mucoromycotina. The spore-bearing sporangiophores of Phycomyces are very sensitive to different environmental signals including light, gravity, wind, chemicals and adjacent objects. They exhibit phototropic growth: most Phycomyces research has focused on sporangiophore photobiology, such as phototropism and photomecism ('light growth response'). Metabolic, developmental, and photoresponse mutants have been isolated, some of which have been genetically mapped. At least ten different genes (named madA through to madJ) are required for phototropism. The madA gene encodes a protein related to the White Collar 1 class of photoreceptors that are present in other fungi, while madB encodes a protein related to the White Collar 2 protein that physically bind to White collar 1 to participate in the responses to light.
Phycomyces blakesleeanus is a species of fungus in the phylum Zygomycota, characterized by its sporangiophores that produce yellow to brown spores. In East and Central Texas, it has been found growing on dung, soil, and decaying organic matter, typically in moist environments with rich nutrient availability. The fungus is commonly isolated from cow and horse dung, as well as from rotting wood and plant debris. Its optimal growth temperature ranges from 20-25°C, making it a common inhabitant of the region's warm and humid climates during spring and summer months.

Phycomyces blakesleeanus(?) fungus on a rotting bolete mushroom in Lick Creek Park. College Station, Texas, September 23, 2020Iron Bridge Trail, College Station, TX 77845, USAIn East and Central Texas, observations of the fungus Phycomyces blakesleeanus were recorded in Lick Creek Park, College Station. On July 9, 2018, the fungus was found on a rotting bolete mushroom, with subsequent photos showing it covering the cap of the mushroom. The fungus was also observed on a molded cap of a bolete mushroom. Nearly two years later, on September 23, 2020, Phycomyces blakesleeanus was again spotted on a rotting bolete mushroom in the same park. These observations suggest that the fungus is present in the area and can be found on decaying mushrooms, particularly boletes, during the summer and early fall months. The repeated sightings indicate a possible recurring presence of the fungus in this specific location.
