'''''Hypholoma''''' is a [genus](/source/genus) of [fungi](/source/fungi) which are quite well known due to the commonness of [sulphur tuft](/source/sulphur_tuft) (''Hypholoma fasciculare'') on stumps in [temperate](/source/temperate) woodlands. Species in this genus are easily recognizable because the dark [spore](/source/spore)s create a distinctive greenish effect on the yellow [cap](/source/pileus_(mycology)) underside. ''Hypholoma'' means "mushrooms with threads" because of the thread-like [veil](/source/partial_veil) that connects the cap to the stem when young and for the bundles of [rhizomorph](/source/rhizomorph)s which radiate outwards from the [stem](/source/stipe_(mycology)) base.[Paul Stamets, [https://books.google.com/books?id=y1fnacRg1AYC&pg=PA334 ''Growing gourmet and medicinal mushrooms''], p. 239, Ten Speed Press, 3rd ed. (2000), {{ISBN|1-58008-175-4}}]
Other well-known species are ''[H. capnoides](/source/Hypholoma_capnoides)'' and ''[H. lateritium](/source/Hypholoma_lateritium)''.
==Synonyms==
Sometimes ''Hypholoma'' has not been considered a genus in its own right, but it has been grouped together with ''[Stropharia](/source/Stropharia)'' and ''[Psilocybe](/source/Psilocybe)'' under the name of ''Geophila'', ''Naematoloma'', or ''Nematoloma''.
