Scytinostromella
''Scytinostromella'' is a genus of crust fungi in the Stereaceae family. The widespread genus contains five species. The genus was circumscribed by Estonian mycologist Erast Parmasto in 1968, who set ''Peniophora heterogenea'' as the type species. Characteristic features of the genus include dimitic hyphae, spores that are both amyloid (mycology), amyloid and asperulate (roughened by many small points or warts), and the presence of cystidia and rhizomorphic strands.

Russulales Genera
The Russulales are an order of the Agaricomycetes, (which include the agaric genera ''Russula'' and ''Lactarius'' and their polyporoid and corticioid relatives). According to the ''Dictionary of the Fungi'' (10th edition, 2008), the order consists of 12 families, 80 genera, and 1767 species. According to ''Species Fungorum'' (January 2016), the order contains 13 families, 117 genera (16 not assigned to a family), and 3,060 species. Russuloid agarics represent an independent evolutionary line of agarics, not directly related to the Agaricales. This group also includes a number of russuloid hypogeous fungi, polypores such as ''Bondarzewia'', some tooth fungi (e.g. ''Auriscalpium vulgare''), and club fungi e.g. ''Artomyces''. Basidiospores in this group are typically ornamented with amyloid warts or reticulation but a few exceptions are known, e.g. ''Heterobasidion annosum''. The genus ''Clavicorona'' was often treated in the Russulales, but its type species, '' C. taxophila'', is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereaceae
The Stereaceae are a family of corticioid fungi in the Russulales order. Species in the family have a widespread distribution, are lignicolous or terrestrial (in leaf litter), and typically saprobic. According to the ''Dictionary of the Fungi'', the family contains 22 genera and 125 species.

Erast Parmasto
Erast Parmasto (28 October 1928 – 24 April 2012) was a noted Estonian mycologist, bioscientist and botanist and onetime director of the Estonian Institute of Zoology and Botany. Parmasto was born in Nõmme. He became a member of the Estonian Institute of Zoology and Botany in 1950 and served as its director from 1985 to 1990. His establishment of a mushroom herbarium in 1950 has since seen recognition of 160,000 samples, 37,000 of which Parmasto himself collected. Parmasto published more than 150 papers and 200 articles during his academic career and his works are commonly used in popular scientific and academic journals in Estonia. His expertise in the field of mycology has resulted in him being nicknamed "Seenevana", or the "grand old man of mushrooms". As a mycologist, the field with which Parmasto was most associated, he was best known for his establishment and enhancement of databases for species of mushrooms within Estonia. He was also the author of the first Estonian-la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Rhizomorph
Mycelial cords are linear aggregations of parallel-oriented hyphae. The mature cords are composed of wide, empty vessel hyphae surrounded by narrower sheathing hyphae. Cords may look similar to plant roots, and also frequently have similar functions; hence they are also called rhizomorphs (literally, "root-forms"). As well as growing underground or on the surface of trees and other plants, some fungi make mycelial cords which hang in the air from vegetation. Mycelial cords are capable of conducting nutrients over long distances. For instance, they can transfer nutrients to a developing fruiting body, or enable wood-rotting fungi to grow through soil from an established food base in search of new food sources. For parasitic fungi, they can help spread infection by growing from established clusters to uninfected parts. The cords of some wood-rotting fungi (like ''Serpula lacrymans'') may be capable of penetrating masonry. The mechanism of the cord formation is not yet precisely und ...

Cystidia
A cystidium (plural cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are often unique to a particular species or genus, they are a useful micromorphological characteristic in the identification of basidiomycetes. In general, the adaptive significance of cystidia is not well understood. Classification of cystidia By position Cystidia may occur on the edge of a lamella (or analogous hymenophoral structure) (cheilocystidia), on the face of a lamella (pleurocystidia), on the surface of the cap (dermatocystidia or pileocystidia), on the margin of the cap (circumcystidia) or on the stipe (caulocystidia). Especially the pleurocystidia and cheilocystidia are important for identification within many genera. Sometimes the cheilocystidia give the gill edge a distinct colour which is visible to the naked eye or wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amyloid (mycology)
In mycology a tissue or feature is said to be amyloid if it has a positive amyloid reaction when subjected to a crude chemical test using iodine as an ingredient of either Melzer's reagent or Lugol's solution, producing a blue to blue-black staining. The term "amyloid" is derived from the Latin ''amyloideus'' ("starch-like"). It refers to the fact that starch gives a similar reaction, also called an amyloid reaction. The test can be on microscopic features, such as spore walls or hyphal walls, or the apical apparatus or entire ascus wall of an ascus, or be a macroscopic reaction on tissue where a drop of the reagent is applied. Negative reactions, called inamyloid or nonamyloid, are for structures that remain pale yellow-brown or clear. A reaction producing a deep reddish to reddish-brown staining is either termed a dextrinoid reaction (pseudoamyloid is a synonym) or a hemiamyloid reaction. Melzer's reagent reactions Hemiamyloidity Hemiamyloidity in mycology refers to a special ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
