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
Geastrum lageniforme is mainly characterized by a mycelial layer with distinct longitudinal cracks, rays with slender tips (arachnoid-like rays), saccate basidiomata and distinctly delimited fibrillose peristome.
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.
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.
From this and the evidence of its existence in early groups one can conclude that presence of a pollination drop is ancestral in conifers, but lost from Araucariaceae and those members of Clade I and II that lack saccate
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).
Base of petals not or only slightly saccate
(0); base of petals conspicuously saccate
Sepals oblong, not saccate
at base, 1.5-2.5(-3) mm long; petals narrowly spatulate, 2.5-4.5(-5) mm long, obscurely papillate at base; anthers ovate, (0.4-)0.5-0.8 mm long.
Both species have "similar large scarlet flowers, pubescence, and peculiar saccate
appendages below which is a conspicuous clear area [extending down the claw]." However, S.
