fluviatile, which has filamentous, clavate and fusoid-ventricose cheilocystidia however in that variety the clavate cystidia are elongate, while in case of Hebeloma mesophaeum these are saccate
This species is recognized by its lignicolous habit, presence of prominent yellowish white subiculum, caespitose growth, small saccate
basidiomata (up to 20 mm wide), and its fibrillose, distinct, and delimited peristome.
The major distinction is between saccate and non-saccate pollen with some illustration in Fig.
The primary subdivision is between saccate pollen (clades I and II) and non-saccate pollen (clades III and IV).
Volva present at the base of stipe, 14-21 X13 mm, saccate, white (4A1), covered with sand, basal rhizomorphs present.
Volva present at the base of the stipe, 24-31 X 21-25 mm, saccate, yellowish white (4A2), smooth, with basal rhizomorphs.
Even then, however, this species can be readily identified by its distinctive inflorescences, which although greatly (or entirely) divested of perigynia continue to display whitish or pale brown saccate appendages, structures which are the persistent portions of otherwise deciduous scales (Wheeler & Goetghebeur, 1997).
the latter known only from Ecuador (Wheeler & Goetghebeur, 1995, 1997), are characterized by deciduous scales and persistent saccate appendages.
Branch appendages: first branch underleaf divided to the base into a lanceolate segment and a saccate segment, first leaf transformed into two saccate lobules.
Branch appendages: first branch underleaf divided to the base into a lanceolate, bifid segment and a explanate segment, first leaf transformed into one saccate lobule.
Base of petals not or only slightly saccate
(0); base of petals conspicuously saccate
9 cm wide with three pairs of hypophyllous glands; nectariferous bracts leathery and succulent, reddish-white, saccate
or pouch-shaped, 2.
