Rosy stinkhorn
(Mutinus ravenelii)
NMV Ga 219020

Rosy stinkhorn has a receptacle dark carmine red or rose-red beneath the gleba. It has narrow pores, usually not constricted below the fertile portion. The gleba is thin, and is soon (3-4 days) disappearing. It has a strong disagreeable smell, like cat dung.
Vemeulen (1999) call this dark carmine red color raspberry-red.

Rosy stinkhorn is rather rare in the Nederlands.

It grows on grained litter and on humous soil, in parks, gardens, sphagnum reed-lands and hay-fields, also on shredded wood and straw.
From June till November (peak: september and end oktober).

In Park Spoorzicht in Diemen I've never seen stinkhorns. To my opinion it means grained litter might be not the most important factor.

Henk van Halm, in Champignons in de Jordaan (1999, p. 165), is writing that the sand below the litter is the important factor. In all the places in the Amsterdam area where he has found Rosy stinkhorn, the places were sprayed with sand in 1967. The sand used to develop the city was originally a bit calciferous and salted seasand.

It is possible that Rosy stinkhorn likes calciferous soil, but because of my observation of Rosy Stinkhorn at nature bridge Zanderij Crailo (absolute non-calciferous sand) I suggest that Rosy stinkhorn prefers non acid soil. Calc buffers acid rain, and buffers the acid from shredded wood.
