Diagram of a basidiomycete stipe with an annulus and volva. In mycology, a stipe (/ s t aɪ p /) is the stem or stalk-like feature supporting the cap of a mushroom. Like all tissues of the mushroom other than the hymenium, the stipe is composed of sterile hyphal tissue. In many instances, however, the fertile hymenium extends down the stipe ...
A simplified diagram of an agaric-type basidioma in (A) the early development stage, and (B) after the body is fully expanded. (1) is the universal veil, the outer layer protecting the developing basidioma; (4) is the volva, the remnant of the universal veil at the base of the basidioma.
Mushrooms Demystified: A Comprehensive Guide to the Fleshy Fungi is a mushroom field and identification guide by American mycologist David Arora, published in 1979 and republished in 1986. [1] All That the Rain Promises and More…:
Glove box A biosafety cabinet ( BSC )—also called a biological safety cabinet or microbiological safety cabinet —is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with (or potentially contaminated with) pathogens requiring a defined biosafety level .
The presence, absence, or structure of the partial veil is an aid to identification of mushrooms. [2] Some fruit bodies may have both a universal and partial veil, others may have only one or the other, while many lack both types of veils. The partial veil may be membranous or cobwebby, and may have multiple layers.
A ring can be seen on the stem of this Gymnopilus junonius mushroom. An annulus is the ring-like or collar-like structure sometimes found on the stipe of some species of mushrooms. The annulus represents the remnants of the partial veil, after it has ruptured to expose the gills or other spore-producing surface.
Developed by Julius Schäffer to help with the identification of Agaricus species. A positive reaction of Schaeffer's test, which uses the reaction of aniline and nitric acid on the surface of the mushroom, is indicated by an orange to red color; it is characteristic of species in the section Flavescentes. The compounds responsible for the ...
An inoculation loop (also called a smear loop, inoculation wand or microstreaker) is a simple tool used mainly by microbiologists to pick up and transfer a small sample of microorganisms called inoculum from a microbial culture, e.g. for streaking on a culture plate.
