THE GENERIC NAMES PROPOSED FOR HYMENOMYCETES—VI*

Brachybasidiaceae, Cryptobasidiaceae, Exobasidiaceae

M . A . DONK * *

SUMMARY

1. In this continuation of the author's nomenclatorial enumeration
not only the three families mentioned in the subtitle are taken into con-
sideration: about ten generic names of fungi which at one time or another
have been attributed to the Exobasidiaceae and which are now excluded
from the Hymenomycetes, are also dealt with.

2, The name' Cryptobasidiaceae is validly published.

INTRODUCTION.—This paper forms the sixth of a series planned to
give an annotated nomenclatorial enumeration of all generic names pro-
posed for Hymenomycetes. For some introductory remarks to the series
and the explanation of some nomenclatorial terms, see Part I (Donk in
Reinwardtia 1:199-203. 1951).

The three families mentioned in the subtitle represent the strictly
'biophilous' element (strictly parasitic in herbaceous and often green
portions of vascular host plants) of the holobasidious Hymenomycetes.
They have sometimes been considered related to the so-called Hetero-
basidiae, among which the Uredinales are reminiscent as regards their
parasitism. Of the families dealt below, Brachybasidiaceae is monotypic.
Another, Cryptobasidiaceae, has recently been delimited and surveyed by
Malencon (in Bull. Soc. mycol. France 69: 77-100. 1953).

The basidiomycetous nature of this latter family has been doubted, and
the information furnished by Malencon would seem insufficient to accept
it as being basidiomycetous for the present. That author (op. cit. p. 96)
called it "Cryptobasidieae," which is inadmissible as the required termina-
tion is '-aceae.' In addition he did not supply a Latin description. Since
I accept the family taxonomically, its name is validly published herewith:

FIG 1. Iehthyodontum sachlanii Scott & Prescott, gen. et sp. nov.; 2. Ichthyodontum
sachlanii var. parorthium Scott & Prescott var. noy.;; 3-5 Dichotypical specimens com-
bining the species and the variety; 6. 7. sachlanit. Front, side and basal views of a
semicell; 7. idem. Larger detail of the polar structure.

* Part I of the present series ("Cyphellaceae") was published in Reinwardtia 1:
199-220. 1951; Part II (Hymenolichenes), in Reinwardtia 2: 435-440. 1954; Part III
( Clavariaceae"), in Reinwardtia 2: 441-493. 1954; Part IV (Boletaceae), in Rein-
wardtia 3: 275-313. 1955; Part V (" Hydnaceae"), in Taxon 5: 69-80, 95-115. 1956.
