Sarcosoma globosum (Sarcosomataceae, Pezizales, Ascomycota) belongs to the rarest
fungi of Lithuania and as an endangered species is listed in the Red Data Book of Lithuania
(1(E) category). Only three documented localities of this ascomycete were known until 1960.
During 2008–2009 the species was recorded again from three new localities in the
northeastern part of Lithuania. The aim of this study was to evaluate three S. globosum
populations by examination of spatial distribution, number and maturity of ascocarps.
Investigation on S. globosum ascocarp biology was carried out in 2009–2011 at each
of the three currently known localities: Žiliškės forest (Panevėžys district), Antazavė forest
(Zarasai district) and Vyžiai forest (Utena district). The fungus started to produce ascocarps in
the second part of March and the first part of April, during or just after the snowmelt. The end
of fructification occurred in the second part of May and first part of June. The development of
individual fruiting bodies lasted up to two months. Total number of fruiting bodies and spatial
distribution varied in different localities. During three years period in Žiliškės forest 10
ascocarps were observed in ca. 400 m 2 area, in Antazavė forest – 6 in ca. 2500 m 2 , and in
Vyžiai forest – 112 in ca. 100 m 2 , respectively. S. globosum exhibited annual fluctuations in
the fruiting patterns in two localities, while in Žiliškės forest it fruited annually. Major part of
ascocarps withered before reaching maturity in all populations. Mature ascocarps, i.e. those
bearing ascospores, were observed in May and only from two localities (Žiliškės and Vyžiai
forests).
