The genus Fistulinella Hennings described in 190 I from Kamerum (Africa),
and only known from there, is reported for the first time from i\<lexico. In
this connection the relationships between the African and tropical American
floras are discussed. Ji1enodora, Vismia and Voch)'sia are Angiosperms only
known from Africa and the tropics of America, including Mexico. Both African
ami . Mexican localities of Fistulinella are in the tropics. It is described F.
mex1cana. Guzmi111 as a new species of lignicolous fungi from a tropical forest
of the State of Campeche. The relationships between F. mexicana Guzm<in and
F. staudtii Henn., F. majm· (Heim) Guzman and F. minor (Heim) Guzman
(the. last two new combinati_ons in the genus Fistulinella were previously
descnbed as lxechmus) are w1dely discussed and shown in a table, and it is
preser:ncd a key _of !dentification for the four species. The genus lxechinus
dcsl?nbed by He1m ~n 1939 from Madagazcar is here considered as synonym
o~ l·tsl~tlmella _followmg_ Horak._ It i~ described the fa!11ily lxechinaceae (Heim)
(,uzman (= tnbu lxechmae Hem1) 111 the order Agancales, close to the families
Boletaccae and Strobilomycetaceae and related to the family Fistulinaceae, of
tl~e order Aphyllophorales. The cylindric and complety free tubes of the hymen_~
um and the gelatinous trama are the principal features both for the genus
l•t.mtlmdla and the new family lxallinaceae.
