al., 1972 : 254); though the type species are widely different, the genus Langermannia

is frequently used by authors subdividing Calvatia (cf. Kreisel, 1962).

Quelet (1873) abandoned previous genera Lycoperdon and Bovista and created

instead Utraria and Globaria, two fully superfluous names that would have had no

Bovista. The name Globaria cannot be used at the generic rank for either is it attributed

to Quelet and illegitimate because it is superfluous (Art. 63) or it is attributed to

Schroeter and then illegitimate because it is homonymous (Art. 64). However as a

subgenus of Bovista it can certainly be used but its paternity must then be given to

Kreisel (Art. 72, note).

The latest emendation of Lycoperdon comes from the exclusion of species devoid Smarda of capillitium with the creation of the genera Vascellum by (1958) and

The actual of the be considered the Kreisel concept genus can one developed by in his study of Lycoperdaceae culminating in his monograph of Bovista of 1967.

According to that concept Lycoperdon should contain species with an endoperidium

with and opening by a pore, having a subgleba large cells, a pseudocolumella a

Typification of the genus

considered the Pers. per Pers. is currently type of the genus

in Lycoperdon. This tradition seems to go back to Cunningham (1942) or some way DEMOULIN: Typification of Lycoperdon 153

to Clements & Shear (1931) who cite the devalidated synonym L. gemmatum Batsch.

This should be choice of typification accepted following Art. 8 (first a lectotype),

Recommendation 7 B (preservation ofcurrent use) and Guide for the determination

of types § 4 C (respect of segregations).

that since the genus Lycoperdon included Myxomycetes for eighteenth century

authors, it was validly published by Linnaeus in 1753 since this is the starting point

for the nomenclature of Myxomycetes (Art. 13) and so that it must be typified

according to Linnaeus' conceptions.

This hypothesis is self destructive. Linnaeus' diagnosis published in the Genera

Fries summarises well this situation (1829 : 28): "Genus Lycoperdon (h.e. Crepitus

If the genus Lycoperdon ofLinnaeus is to be typified it seems that following already
