Image of Inocybe dulcamara (Pers.) P. Kumm. 1871

Description:

Gills. - Slo.: klobuevinasta razcepljenka - Habitat: Semi-ruderal river shore overgrown with young Salix purpurea and some Alnus incana (not S. glutinosa!), a few years ago bulldozer-ed calcareous alluvial gravel, flat terrain, sunny place, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 335 m (1.100 feet), alpine phytogeographical region. - Substratum: Gravel, some silt and sand among river pebbles, nutrient poor ground (mostly fallen Salix leaves in different state of disintegration). - Comments: Several experts have been consulted for determination. No consensus has been reached yet. This is what has been proposed to be considered seriously: Tubaria conspersa (http://mycologie.catalogne.free.fr/ImagesPhoto2009-1/Tubaria_conspersa_1.jpg), Alnicola dubis = Rhodocybe dubia (Moser), Inocybe (section Mallocybe), Alnicola subconspersa (Khn. ex Orton) Bon 1979. Most probable determination seems to be Inocybe dulcamara. See reference (7) and (8). However, nothing perfectly fits to the mushrooms found according to sources available to me. Any additional help would be appreciated. Description: Growing solitary but many sporocarps scattered around. Pileus diameter 15 -30 mm (0.6 - 1.5 inch), no distinct taste or smell (I am poor in that), flesh brittle, stipe quite fibrous, hollow. Almost all pileus have distinct remnants of veil on top. SP brown. Sporocarps heavily shrunk after drying. - Spores seem smooth in profile, but show grainy structure on the surface (poor microscopy? - Tiny warts may not be visible in water?). Dimensions of spores: 9.7 (SD = 0.6) x 5.3 (SD = 0.6) micr., Q = 1.82 (SD = 0.11), n = 30. Motic B2-211A, magnification 1.000 x, oil, in water. Other scope pictures gain 400x. - Ref.: (1) Personal communication with Mr. Gregor Podgornik Mr. Anton Poler, Mr. Bojan Rot.
