Hedelmä on kuiva, avautuva ja sen pinnalla on glokidioita.
The stipe is smooth and dry on the surface and has a firm texture on the inside.
Lakin reunoilla ei ole säteittäisiä uurteita, eikä sen pinnalla ole pilkkuja erotuksena muista kärpässienilajeista.
There is no modulation of light and shade, no illusion of three-dimensionality on the surface.
Jos taas toruksen uloimman pinnan sädettä merkitään p:llä ja sisimmän pinnan sädettä q:llä (niin että R = p + q 2 {\displaystyle R={\frac {p+q}{2}}} ja r = p − q 2 {\displaystyle r={\frac {p-q}{2}}} ), toruksen pinta-ala ja toroidin tilavuus on: A = 4 π 2 ( p + q 2 ) ( p − q 2 ) = π 2 ( p + q ) ( p − q ) V = 2 π 2 ( p + q 2 ) ( p − q 2 ) 2 = 1 4 π 2 ( p + q ) ( p − q ) 2 {\displaystyle {\begin{aligned}A&=4\pi ^{2}\left({\frac {p+q}{2}}\right)\left({\frac {p-q}{2}}\right)=\pi ^{2}(p+q)(p-q)\\V&=2\pi ^{2}\left({\frac {p+q}{2}}\right)\left({\frac {p-q}{2}}\right)^{2}={\tfrac {1}{4}}\pi ^{2}(p+q)(p-q)^{2}\end{aligned}}} Koska torus on kahden ympyrän tulo, sen pinnalla olevan pisteen sijainti voidaan ilmoittaa eräänlaisella muunnetulla versiolla pallokoordinaateista.
Expressing the surface area and the volume by the distance p of an outermost point on the surface of the torus to the center, and the distance q of an innermost point (so that R = p + q/2 and r = p − q/2), yields A = 4 π 2 ( p + q 2 ) ( p − q 2 ) = π 2 ( p + q ) ( p − q ) V = 2 π 2 ( p + q 2 ) ( p − q 2 ) 2 = 1 4 π 2 ( p + q ) ( p − q ) 2 {\displaystyle {\begin{aligned}A&=4\pi ^{2}\left({\frac {p+q}{2}}\right)\left({\frac {p-q}{2}}\right)=\pi ^{2}(p+q)(p-q)\\V&=2\pi ^{2}\left({\frac {p+q}{2}}\right)\left({\frac {p-q}{2}}\right)^{2}={\tfrac {1}{4}}\pi ^{2}(p+q)(p-q)^{2}\end{aligned}}} As a torus is the product of two circles, a modified version of the spherical coordinate system is sometimes used.
