The stalk and sorus also play important roles in the amoeba farms.
sorus A reproductive structure in certain amoebas, fungi and lichens.
may be covered with a membrane-like protective layer called the indusium.
Collect the spores by tapping or scraping the spore-bearing sori (singular sorus
) into an envelope, and allow them to dry for 1 day or so.
1); globose to cylindrical: 3-5 mm long; a single sorus
with one central columella of host tissue and a longitudinally rupturing peridium (Fig.
Following the work of Good (1981), sporangial maturation within a sorus
is interpreted as simultaneous rather than gradate, as interpreted earlier (Holmes, 1981).
Mature spores are released en masse as the tip of the sorus
erodes so that sudden decreases in sorus
area on a plant reflect pulses in spore release.
The larval period lasts three to four weeks after which pupation occurs in the sorus
. Adult beetles emerge after three weeks and appear to overwinter as adults at the base of the tussock (Kontkanen 1936; P.
"June is probably the least opportunistic Sorus
," Cohen explained.
But even the runner up, George Sorus
, he noted, bid $164 million and didn't have a user.
(sori)--Region where sporangia are clustered on reproductive fern fronds.
Larger pinnae mostly more than 5cm long; rhizome robust: indusium covering top of sorus
We estimated sorus
area in Pterygophora in the same way except that we measured all sori since individuals rarely had [greater than] 10 sorus-bearing sporophylls.
appalachianum are often uniformly golden brown (sometimes weakly bicolored), the leaves are often larger and widest near the base ( but not always), the spores are less than 52[micro]m, and there are usually more than 40 sporangiasters per sorus
