Madison Heights, two fungi.
Agaricus californicus []
Lawn on NW corner of Marengo and Fillmore.
| | GEN | | med mushroom, scattered, lawn |
| | ST | | 70x15mm, wavy but even width, whitish to sl brownish (whiter than cap)| ring | | thick, short, ascending, whitish, falling off in age |
sl bulb at base under ground, fresh sl sweetish odor (fades quickly after picked), hollow in v center, end not bruising |
| | CAP | | ~100mm wide, flat but wavy, shiny but breaking into v fine shallow cracks in age, whitish aging brownish, K+y/o (when young), turning yellish if rubbed |
| | FLESH | | 10mm thick in center, whitish to sl brownish, K+y/o |
| | GILL | | free, whitish to pinkish to dk brown, 10mm thick |
| | SPORE | | print med-dk brown, clear to maybe brownish, ellip-oblong, smooth, 5.1-5.7x3.6-4.5um |
This seems to match the description perfectly for a change... except the spores are way too small, grr.
(20070929) I've re-opened this case upon discovering more info on the web. In particular, mykoweb's pictures and description seems to suggest A. californicus over A. arvensis. Further, I must note now that I've yet to see a single specimen larger than about 10-12cm (and I've studied many since this first observation). Lastly, if the inference is correct, A. arvensis doesn't have as strong of a K+y reaction as A. californicus. Interestingly, neither mykoweb.com nor mushroomobserver.org mention the one as a similar species to the other. For all that the descriptions make them sound very similar (to me, at least) they must be obviously different in the field.
Coprinus plicatilis []
Lawn on NW corner of Marengo and Fillmore.
| | GEN | | minute mushroom, small groups, in lawn or dung |
| | ST | | 55x0.8mm, white to translucent, fragile |
| | CAP | | v fragile, greyish brownish translucent, 10x5mm, v convex rounded, plicate, esp brownish in center, not umbonate |
| | GILL | | black-edged or blackening in age |
| | SPORE | | print black, clearly visible at 30x, smooth, ellip, acute at one end, 15-16.5x12.5-13.5um, v dk brown to black |
Must be either
C. disseminatus or
C. plicatilis due to the minute stature, clustered habit, and pleated translucent cap. But the spores are way too big.
(20071006) Consensus seems to go with C. plicatilis.
