Discinaceae
The Discinaceae are a family of ascomycete fungi, the best known members of which are the false morels of the genus ''Gyromitra''. Originally erected by Erich Heinz Benedix in 1961, it was found to be a discrete clade in a molecular study of ribosomal DNA by mycologist Kerry O'Donnell in 1997. As of 2008, the family is thought to contain 5 genera and 58 species. As of 2022, the GBIF accepts '' Discina'' (27 spp), ''Gymnohydnotrya'' (4 spp), ''Gyromitra'' (73 spp), ''Hydnotrya'' (52 spp) and '' Maublancomyces'' (1 sp). But calls ''Neogyromitra'' and ''Pseudorhizina'' doubtful. Members in the family Discinaceae are known to have epigeous and hypogeous species, and are characterized by ascomata composed of an inner layer of interwoven hyphae and an outer layer composed of elongated cells arranged perpendicular to its exterior. Discinaceae include species possessing saddle-shaped apothecia and hypogeous truffles. Discinaceae possess cylindrical, 8-spored, tapered asci and asco ...

Discina Perlata
''Discina perlata'', commonly known as pig's ears is a brown to tannish, wrinkled, cup- or ear-shaped fungus, sometimes with short, stout stalk. The spores of ''D. perlata'' are quite similar to those of mushrooms in the genus ''Gyromitra'', so that some mycologists classify it there. Description The cup measures wide; with a disc-like, whitish exterior, and a dark brown to tan interior. The cup is often wrinkled to convoluted, with the edges turned downward. The flesh is brittle. The stipe (when present) is long and thick; it is brownish-tan in color. It is considered edible by some authors, but not others; it can be confused with other potentially toxic species. It should be cooked before consumption. Microscopic characteristics The spores are 30–35 x 12–14 μm, spindle shaped, minutely warted, with three oil drops and knobs at each end, located in the cup. Similar species ''Disciotis venosa'' is more deeply veined, and has smooth spores; it is typically fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyromitra
''Gyromitra'' () is a genus of about 18 species of ascomycete fungi. They are a false morel - a frequently toxic mushroom that can be mistaken for edible mushrooms of the genus ''Morchella'' (morels). Taxonomy The name ''Gyromitra'' comes from ''gyro'' meaning ''convoluted'' and ''mitra'' meaning ''turban''. Analysis of the ribosomal DNA of many of the Pezizales showed the genus ''Gyromitra'' to be most closely related to the genus '' Discina'', and also ''Pseudorhizina'', ''Hydnotrya'', and only distantly related to '' Helvella''. Thus the four genera are now included in the family Discinaceae. Species The genus consists of the following species: * ''Gyromitra ambigua'' * '' Gyromitra anthracobia'' * '' Gyromitra brunnea'' - known as a false morel * ''Gyromitra bubakii'' * '' Gyromitra californica'' * ''Gyromitra caroliniana'' (North America) * ''Gyromitra esculenta'' (Pers.)

Discina (fungus)
''Discina'' is a genus of ascomycete fungi related to the false morels of the genus ''Gyromitra''. There are about 20 species in the genus. They bear dish- or cup-shaped fruit bodies. The best known member is the pig ear ('' D. perlata''), which is deemed edible after thorough cooking, although is viewed with suspicion given its relation to the highly toxic false morel The name false morel is given to several species of mushroom which bear a resemblance to the highly regarded true morels of the genus '' Morchella''.

False Morel
The name false morel is given to several species of mushroom which bear a resemblance to the highly regarded true morels of the genus '' Morchella''. Like ''Morchella'', false morels are members of the Pezizales, but within that group represent several unrelated taxa scattered through the families Morchellaceae, Discinaceae, and Helvellaceae, with the epithet "false morel" most often ascribed to members of the genus ''Gyromitra''. Compared to morels When gathering morels for mushrooms, care must be taken to distinguish them from potentially poisonous lookalikes. While a great many morel lookalikes, and even morels themselves are toxic or cause gastrointestinal upset when consumed raw, some, such as '' Gyromitra esculenta'' remain toxic even after conventional cooking methods. Although some false morels can be eaten without ill effect, others can cause severe gastrointestinal upset, loss of muscular coordination (including cardiac muscle), or even death.

Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomyce ...

Ectomycorrhizal
An ectomycorrhiza (from Greek ἐκτός ', "outside", μύκης ', "fungus", and ῥίζα ', "root"; pl. ectomycorrhizas or ectomycorrhizae, abbreviated EcM) is a form of symbiotic relationship that occurs between a fungal symbiont, or mycobiont, and the roots of various plant species. The mycobiont is often from the phyla Basidiomycota and Ascomycota, and more rarely from the Zygomycota. Ectomycorrhizas form on the roots of around 2% of plant species, usually woody plants, including species from the birch, dipterocarp, myrtle, beech, willow, pine and rose families. Research on ectomycorrhizas is increasingly important in areas such as ecosystem management and restoration, forestry and agriculture. Unlike other mycorrhizal relationships, such as arbuscular mycorrhiza and ericoid mycorrhiza, ectomycorrhizal fungi do not penetrate their host's cell walls. Instead they form an entirely intercellular interface known as the Hartig net, consisting of highly branched hyphae formi ...

Morchellaceae
The Morchellaceae are a family of ascomycete fungi in the order Pezizales. According to a standard reference work, the family has contained at least 49 species distributed among four genera. However, in 2012, five genera that produce ascoma that are sequestrate and hypogeous were added. The best-known members are the highly regarded and commercially picked true morels of the genus ''Morchella'', the thimble morels of the genus ''Verpa'', and a genus of cup-shaped fungi ''Disciotis''. The remaining four genera produce the sequestrate fruit bodies. Analysis of the ribosomal DNA of many of the Pezizales showed the three genera ''Verpa'', ''Morchella'', and ''Disciotis'' to be closely related. Thus they are now included in the family Morchellaceae. Genera ''Costantinella'' (anamorph) ''Disciotis'' (terrestrial) ''Morchella'' (terrestrial) ''Verpa'' (terrestrial) ''Kalapuya'' (hypogeous) ''Imaia'' (hypogeous) ''Leucangium'' (hypogeous) ''Fischerula'' (hypogeous) Description Other ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...
