Examples from the Web for hypha
When the hypha of a uredine attacks a cell it is unable to perforate it with its whole diameter.
De Bary had previously hinted that the hypha might be attracted by some chemical ingredient of the host plant.
Easily distinguishable from all similar moulds by the absence of mycelium or of anything like a hypha.
If the hypha is the morphological test of a fungus, then it is plain that the slime-moulds are not fungi.
The "real tug of war" comes when the hypha is face to face with the ectoplasm.
- any of the filaments that constitute the body (mycelium) of a fungus
C19: from New Latin, from Greek huphē web

- One of the long slender tubes that develop from germinated spores and form the structural parts of the body of a fungus. In many species of fungi, hyphae are divided into sections by cross walls called septa. Each section contains at least one haploid nucleus, and the septa usually have perforations that allow cytoplasm to flow through the hypha. A large mass of hyphae is known as a mycelium, which is the growing form of most fungi. From time to time, hyphae develop reproductive structures that are partitioned from the hypha by holeless septa. In many species, these structures are microscopic; in others, they are visible and large. Mushrooms and shelf fungi are visible reproductive structures of fungi.
