What is Hymenium in mushroom?
What is Hymenium in mushroom?
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. The position of the hymenium is traditionally the first characteristic used in the classification and identification of mushrooms.
What is Hartig net in fungi?
A Hartig net is a complex of fungal hyphae found in the intercellular spaces between the cortical cells of a root. The massive surface area provided by the Hartig net is the main place for exchange of substances between the plant and fungus.
Where are ericoid mycorrhizae found?
Ericoid mycorrhizas are characterized by fungal coils that form in the epidermal cells of the fine hair roots of ericaceous species.
What is Ectendomycorrhizae?
mikaloe is a chlamydospore-producing fungus, found predominantly in disturbed mineral soils, whilst W. rehmii thrives in peaty soils, but does not produce chlamydospores. The formation of ectendomycorrhizas begins with formation of a Hartig net, which grows behind the apical meristem of the growing root.
What are Adnate gills?
Adnate mushroom gills are broadly attached to the stalk slightly above the bottom of the gill, with most of the gill fused to the stem. An anther is adnate when fixed by its whole length to the filament.
What does Pycnidia mean?
A pycnidium (plural pycnidia) is an asexual fruiting body produced by mitosporic fungi, for instance in order Sphaeropsidales (Deuteromycota, Coelomycetes) or order Pleosporales (Ascomycota, Dothideomycetes). It is often spherical or inversely pearshaped (obpyriform) and its internal cavity is lined with conidiophores.
What is the difference between Ectomycorrhizae and Endomycorrhizae?
What is the Difference Between Endo and Ecto Mycorrhizae? Endomycorrhizal Fungi form resource exchange mechanisms on the inside of the plant’s root cells, intracellularly (and the hyphae extend outside the root). Ectomycorrhizal Fungi form exchange mechanisms outside of the root cells, extracellularly.
What is Endomycorrhiza and Ectomycorrhiza?
Ectomycorrhizae and Endomycorrhizae are two types of symbiotic relationships which exist between fungi and the roots of higher plants. Ectomycorrhizae, as the name suggests, do not penetrate deep into the plant (the cortical cells). Endomycorrhiza, on the other hand, tends to penetrate deeper (into the cortical cells).
Which of the following is a ericoid mycorrhizae?
Ericoid Mycorrhizal Fungi. The Ericaceae are dominant plants of acid heathland and upland soils including the genera Calluna, Erica, Vaccinium, Azalea, Rhododendron, and the Epacrids of Australasia which grow in dry sandy soils.
What are Decurrent gills?
If the whole gill extends down the stem, it is called decurrent. The edge of a decurrent gill is usually not horizontal, but approaches the stem at a slant, so the gill constantly gets wider as it approaches the stem.
What are attached gills?
Mushroom Gill Attachments. The gills (lamellae) attach to the stem (stipe) in many unique ways. The characteristics of a mushroom’s gill attachment aid in the identification. The age of a specimen is significant when observing gill attachments as they could break away (Seceding) as the mushroom matures.
What is the function of Rhizomorph?
rhizomorph, a threadlike or cordlike structure in fungi (kingdom Fungi) made up of parallel hyphae, branched tubular filaments that make up the body of a typical fungus. Rhizomorphs act as an absorption and translation organ of nutrients.
What is hyaline membrane disease?
Hyaline Membrane Disease Hyaline membrane disease is a form of acute lung injury seen in neonates and is the pathologic correlate of neonatal RDS.
What are hyaline membranes made of?
These hyaline membranes may look relatively uniform, but they are actually composed of a myriad of materials, including cytoplasm and nucleoplasm of dead cells, plasma transudate, and amniotic fluid. Hyaline membranes form within 3 to 4 hours of birth and are well developed by 12 to 24 hours.
Does hyaline membrane disease predict neonatal mortality and morbidity?
Hyaline membrane disease is one of the significant predictor of neonatal morbidity and mortality. In this study proportion of hyaline membrane disease was 40%, this is consistent with study conducted in Iraq, 42.2% [17], in Black lion Hospital, Ethiopia 42.9% [41].
What is the prevalence of hyaline membrane disease in Ethiopia?
In this study proportion of hyaline membrane disease was 40%, this is consistent with study conducted in Iraq, 42.2% [17], in Black lion Hospital, Ethiopia 42.9% [41].
