AI-generated description

Resinicium bicolor is a species of fungus that grows as a crust-like formation on trees, typically on deciduous species such as oak and elm. It has a two-toned appearance, with a white or light-colored upper surface and a brown or dark-colored lower surface. In East and Central Texas, Resinicium bicolor is commonly found in wooded areas, particularly in the fall and winter months when it produces its fruiting bodies. It is often encountered on trees along streams and rivers, as well as in urban landscapes where deciduous trees are prevalent. The fungus is considered saprotrophic, obtaining its nutrients by breaking down dead organic matter, and is not typically considered harmful to the trees it grows on.

AI-generated summary of observations

Observations of the fungus Resinicium bicolor in East and Central Texas were made on a large fallen pine on Little Lake Creek Loop Trail in Sam Houston National Forest, Richards, Texas, on May 23, 2018. The fungus was found growing on rotting wood, with a corticioid shape and a spreading habit. It was observed to have distinct details and texture, with multiple photographs taken to document its appearance. The fungus was growing on a single large fallen pine, with no other substrates noted. All observations were made in the same location, suggesting that Resinicium bicolor may be commonly found on fallen pines in this region. The consistent presence of the fungus on rotting wood suggests a possible role in decomposition processes in East and Central Texas ecosystems.
