Lomentospora prolificans is a soil fungus, and has been found in the soils of ornamental plants [b] and greenhouse plants. [ c ] Along with other fungi, Lomentospora prolificans has been isolated from soils of Ficus benjamina and Heptapleurum actinophyllum plantings in hospitals, suggesting that these materials have potential to serve as ...
Mature sclerotia will produce spore-bearing structures known as clavula, where basidia and basidiospores can form. During the winter, the sclerotia begin to germinate and produce mycelium under a snow cover. The mycelium eventually spreads, produces infection cushions, and penetrates plant tissue.
The fertile leaves appear first; their green color slowly becomes brown as the season progresses and the spores are dropped. The spore-bearing stems persist after the sterile fronds are killed by frost, until the next season. The spores must develop within a few weeks or fail. The Osmundastrum cinnamomeum fern forms huge clonal colonies in ...
This is a glossary of some of the terms used in phytopathology.. Phytopathology is the study of plant diseases. It is a multi-disciplinary science since prerequisites for disease development are the presence of a susceptible host species, a pathogen and the appropriate environmental conditions.
1. Uncinula necator, a powdery mildew that grows on grapes Fungi that grow on host plants. Subdivided into powdery mildew ("true"), downy mildew ("false"), and dark mildew. 2. The plant disease caused by such fungi. [236] mitosis The normal division of a nucleus. Results in two child nuclei with the same number of chromosomes as the parent. [237]
In several species the hyphal system is dimitic. The spore-bearing surface is initially covered in a layer of weakly branched hyphidia below which the basidia are formed. The basidia are tremelloid (ellipsoid and vertically septate), giving rise to long, sinuous sterigmata or epibasidia on which the basidiospores are produced. These spores are ...
The spore print is white; spores are cylindrical, smooth, and measure 7–11 by 2–3 μm. [12] The basidia (spore-bearing cells) have a shape ranging from cylindrical to club-shaped, and dimensions of 20–40 by 3–5 μm.
Gleba (/ ˈ ɡ l iː b ə /, from Latin glaeba, glēba, "lump") is the fleshy spore-bearing inner mass of certain fungi such as the puffball or stinkhorn. The gleba is a solid mass of spores, generated within an enclosed area within the sporocarp.
