Capilano River Regional Park – Great Fir Trail. Starting at the hatchery, go across the closest bridge and turn right onto the Second Canyon Trail. Keep walking until you notice a hill on your left, which is part of the Great Fir Trail. After walking for about a minute up the hill, close to the top before it levels out, mushrooms were on left on an incline in the soil.

Notes
Hebeloma sect. Hebeloma. Cortina and inequilateral (top and bottom spores with different curvatures), slighly dextrinoid spores, distinctive fusoid ventricose cheilocystidia with cylindrical apex and ventricose base 8-10 u wide. The pileus is convex ranging from 2.3-5.0 cm broad and having a circular to oval shape. The pileus is lighter brown in the center fading to a light to whitish brown towards the margin and the edge. The edge of the pileus appears to be lined with whitish-brown remnants of a cobwebby veil. The lamellae are freely attached, broad, and a very pale brown colour. There are also acute lamellae starting from the edge of the pileus towards the center located in between the larger lamellae. The stipe is 7-9 cm long and 4-5 mm thick. It is whitish-brown being paler near the apex and browner towards the base. Note that the colours mentioned thus far were when the mushroom was fresh, but when the pictures were taken in the Herbarium they appear more of a yellow/orange brown rather than whitish brown. Also, when the mushrooms are dried they are more of a brown colour and the gills are a darker orangey-brown. The smell of the mushroom was very strong, but hard to describe. It was probably more pungent rather than aromatic. Another defining characteristic of this mushroom is the strange taste, which again is difficult to describe but is very distinct almost like burnt toast. The spore print gave a cinnamon-brown colour. Spore sizes ranged from 10-12.5 (avg. 12.5) μm x 5-10 (avg. 7.75) μm. Spores were more or less inequilateral, staining red in Melzer’s and appearing smooth in KOH, but slightly roughened in Melzer’s. Cheilocystidia were apparent on the bottom edge of the gills and were fusoid-ventricose having enlarged swollen bases and long, cylindrical necks that were hyaline in KOH. Note: I think that this mushroom belongs to either H. subsacchariolens or H. remyi because both these species had spores that were similar in size, inequilateral, and dextrinoid. Furthermore, they had fusoid-ventricose cheilocystidia and a distinct odour and taste. However, this mushroom differed from H. subsacchariolens in the size of the pileus and stipe. Also, the odour was described as fragrant rather than pungent and the spores were described as weakly dextrinoid with cheilocystidia variable in shape, which not the case in this mushroom. Hebeloma remyi differed from this mushroom in that some of the cheilocystidia were filamentous rather than fusoid-ventricose and the taste and odour were described as raphanoid which disagrees with what was observed in this mushroom. However, H. remyi spores were described as being smooth in KOH and fairly ornamented in Melzer’s, which was apparent in this mushroom.
