dendrohyphae

Dendrohyphae are microscopic, tree-like structures produced by certain fungi, particularly those in the phylum Ascomycota. These hyphae are characterized by their branching patterns, which resemble the dendrites of a neuron or the branches of a tree. They are not a standard morphological feature found in all fungi, but rather a specialized adaptation observed in specific fungal species.

The formation of dendrohyphae is typically associated with their role in host penetration or nutrient acquisition. In plant pathogenic fungi, dendrohyphae can aid in the invasion of host tissues by secreting enzymes that break down cell walls and by mechanically pushing through the plant material. The branching structure can increase the surface area for enzyme secretion and absorption of nutrients.

In some saprophytic fungi, dendrohyphae may play a role in accessing complex or recalcitrant substrates. Their intricate branching might allow them to infiltrate micro-crevices in organic matter, maximizing contact with the food source. The term itself, "dendrohyphae," derives from the Greek words "dendron" meaning tree and "hyphae" referring to the filamentous structures of fungi. Their presence is usually observed through microscopic examination of fungal growth on or within a substrate. The precise ecological or pathogenic significance of dendrohyphae can vary greatly depending on the specific fungal species and its environment.
