Notes:
Coprinellus saccharinus, Sweden, Eskilstuna. 18/6 – 17. Usually, all of the coprinoid mushrooms in Coprinellus sect micacei, are grouped as C. micaceus in Sweden. A couple of days back I found what looked like something other than C. micaceus sensu stricto due to the absence of caulocystidia on the stipe. Microscopy revealed that it indeed was C. saccharinus, which is not reported in Sweden as a separate species.

Description:

Pileus: 20-27 × 20-36 mm; broadly campanulate and ovoid, slightly umbonate. Light granulose velum. Color is pale cream to ocre with a darker center.

Lamellae: crowded to adnexed, sometimes free. White at first, then darkening to black. Deliquescent.

Stipe: 33-52 × 3-6 mm. White or light cream colored, radially fibrillose, thickens towards the base, hollow.

Taste – indistinct, smell – indistinct

Ecology: Growing caespitose and gregarious under Platanus and Quercus

Spores: Broadly ovoid to mitriform, more often submitriform. Reddish brown in H2O and subopaque with a rounded central germpore.

Pleurocystidia: present

Caulocystidia: abscent
