Astraeus Asiaticus
''Astraeus asiaticus'' is a species of false earthstar in the family Diplocystaceae. Described as a new species in 2007, it was originally found in north and northeastern areas of Thailand, where it grows in sandy or laterite-rich soil in dry lowland dipterocarp forests. The species has a wide distribution in Asia.

Roy Watling
Roy Watling , PhD., DSc, FRSE, F.I.Biol., C.Biol., FLS (born 1938) is a Scottish mycologist who has made significant contributions to the study of fungi both in identification of new species and correct taxonomic placement, as well as in fungal ecology. Biography Dr Watling served as the Head of Mycology and Plant Pathology, as Acting Regius Keeper of the Royal Botanic Garden Edinburgh and as a visiting professor at Ramkhamhaeng University in Bangkok, Thailand. He was awarded a Patrick Neill Medal and an Outstanding Contribution to Nature Award from the Royal Society for the Protection of Birds.

Astraeus (fungus)
''Astraeus'' is a genus of fungi in the family Diplocystaceae. The genus, which has a cosmopolitan distribution, contains nine species of earthstar mushrooms. They are distinguished by the outer layer of flesh (exoperidium) that at maturity splits open in a star-shape manner to reveal a round spore sac. Additionally, they have a strongly hygroscopic character—the rays will open when moist, but when hot and dry will close to protect the spore sac. Species of ''Astraeus'' grow on the ground in ectomycorrhizal associations with trees and shrubs. Description The mycelium of immature specimens is fibrous, and originates from all parts of the surface. The peridium is roughly spherical, and made of two distinct tissue layers. The outer layer, the exoperidium, is thick, leathery, and initially inseparable from the inner layer (endoperidium). At maturity, the exoperidium bursts open into several pointed "rays". The inner layer of tissue, the endoperidium, is thin, like a membrane. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Laterite
Laterite is both a soil and a rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock, usually when there are conditions of high temperatures and heavy rainfall with alternate wet and dry periods. Tropical weathering (''laterization'') is a prolonged process of chemical weathering which produces a wide variety in the thickness, grade, chemistry and ore mineralogy of the resulting soils. The majority of the land area containing laterites is between the tropics of Cancer and Capricorn. Laterite has commonly been referred to as a soil type as well as being a rock type. This and further variation in the modes of conceptualizing about laterite (e.g. also as a complete weathering profile or theory about weathering) has led to calls for the term to be abandoned alto ...

Dipterocarp
Dipterocarpaceae is a family of 16 genera and about 695 known species of mainly tropical lowland rainforest trees. The family name, from the type genus ''Dipterocarpus'', is derived from Greek (''di'' = two, ''pteron'' = wing and ''karpos'' = fruit) and refers to the two-winged fruit. The largest genera are ''Shorea'' (196 species), ''Hopea'' (104 species), ''Dipterocarpus'' (70 species), and ''Vatica'' (65 species).Ashton, P.S. Dipterocarpaceae. In ''Tree Flora of Sabah and Sarawak,'' Volume 5, 2004. Soepadmo, E., Saw, L. G. and Chung, R. C. K. eds. Government of Malaysia, Kuala Lumpur, Malaysia. Many are large forest-emergent species, typically reaching heights of 40–70 m, some even over 80 m (in the genera ''Dryobalanops'', ''Hopea'' and ''Shorea''), with the tallest known living specimen (''Shorea faguetiana'') 93.0 m tall. The species of this family are of major importance in the timber trade. Their distribution is pantropical, from northern South America to Africa, the Sey ...

Astraeus Odoratus
''Astraeus odoratus'' ( th, เห็ดเผาะหนัง; ''Het pho nang'' เห็ดเผาะหนัง, ''Het pho'' เห็ดเผาะ, or ''Het nang'' เห็ดหนัง, the latter meaning "skin mushroom") is a species of false earthstar in the family Diplocystaceae. Described as a new species in 2004, it was originally found in the Thai highlands growing in sandy or laterite-rich soil in dry lowland dipterocarp forests. The species is found in Southeast Asia. Description Fruit bodies begin as brownish spheres or flattened spheres, partially submerged in the earth. The outer tissue layer, the exoperidium, splits open in a star-like fashion into 3–9 rays. The rays are hygroscopic, spreading out when moist and curling inward when dry. The fully expanded fruit body measures up to in diameter. Fresh fruit bodies have an odor similar to moist soil. The spores are spherical, covered with spines, and measure 7.5–15.2 µm. The ornamentation of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boletales
The Boletales are an order of Agaricomycetes containing over 1300 species with a diverse array of fruiting body types. The boletes are the best known members of this group, and until recently, the Boletales were thought to only contain boletes. The Boletales are now known to contain distinct groups of agarics, puffballs, and other fruiting-body types. Taxonomy The order Boletales originally was created to describe boletes, but based on micromorphological and molecular phylogenetic characteristics, a large number of nonbolete species have recently been reclassified to belong to this group, as well. The order also includes some gilled mushrooms, in the families Gomphidiaceae, Serpulaceae, Tapinellaceae, Hygrophoropsidaceae, and Paxillaceae, which often have the same flesh texture as the boletes, spore-bearing tissue which is also easily separable from the cap, and similar microscopic characteristics of spores and cystidia.

Fungi Described In 2007
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
